Cushions trap air at the end of stroke by blocking or restricting the discharge port. The trapped air is diverted through a small needle valve which generates a back pressure on the discharge side of the piston. This back pressure resists the forces exerted on the internal parts of the rotary actuator, thus causing a slowing of the external mass. Stroke adjustors are screw-type adjustable stops at end of rotation. They should be used when the exact final position of rotation is best determined on the assembled machinery or when final position requirements may vary with different machine set ups. CAUTION: Cushion needles should be set between one half and one full turn from seated position. Setting should result in continuous speed reduction throughout the cushion length. Needle adjustment is set too far closed when there is an abrupt change in speed as the actuator enters the cushion. Never operate with needle in seated position or unscrewed beyond the point where the seal relief in the thread is visible. CAUTION: Cushion needle adjustment is a crucial factor in achieving optimum cushion performance. If the needle valve setting is too far open cushion capacity will be reduced or rendered ineffective; if set too far closed, cushion action will generate shock and pressure spikes in excess of actuator rating. NOTE: Cushions and stroke adjustors are not available on the same cylinder end cap for standard models. Consult factory for special design considerations. A S E R I E S M O O G F L O - T O R K 9

When properly sized and adjusted, cushions may also provide smooth deceleration, external energy absorption and noise reduction. Cushions trap fluid at the end of stroke by blocking or restricting the discharge port. The trapped fluid is diverted through a small needle valve which generates a back pressure on the discharge side of the piston. I N T E R N A L S T R O K E A D J U S T O R A N D A D J U S T A B L E C U S H I O N ST ROKE ADJUSTORS Stroke adjustors are screw-type adjustable stops at end of rotation. They should be used when the exact final position of rotation is best determined on the assembled machinery or when final position requirements may vary with different machine set ups. ST ROKE ADJUSTORS & ADJUSTABLE CUSHION Adjustable cushion and stroke adjustors are combined as a single end of stroke option. The Ohio Oscillator design moves the cushion engagement position along with the end of stroke adjustment so the full engagement length of the cushion is retained at any stroke adjustment setting. CAUTION: Cushion needles should be set between one half and one full turn from seated position. Setting should result in continuous speed reduction throughout the cushion length. Needle adjustment is set too far closed when there is an abrupt change in speed as the actuator enters the cushion. Never operate with needle in seated position or unscrewed beyond the point where the seal relief in the thread is visible. A S E R I E S O H I O O S C I L L A T O R The back pressure resists the forces exerted on the rack by the propelling action of the actuator and the slowing of external mass which imparts engery into the actuator through the shaft. A check valve is included to bypass the cushion action at the start of rotation in the reverse direction. NOTE: Cushions needle adjustment is a crucial factor in achieving optimum cushion performance. If the needle valve setting is too far open, cushion capacity will be reduced, or rendered ineffective; if set too tight, cushion action will generate shock and pressure spikes in excess of actuator rating. * C A U T I O N : S t r o k e A d j u s t o r s a n d c u s h i o n s s h o u l d n e v e r b e a d j u s t e d w h i l e t h e s y s t e m i s u n d e r p r e s s u r e.

29 E N D C A P O P T I O N S EXTERNAL ST ROKE ADJUSTORS External stroke adjustors permit 0-30º of adjustment at the end of rotation. The adjustor stop, which contains the port, is set in position with a wrench on external flats and locked in place with a jam nut against a thread seal. M O D E L S T O M O D E L S A N D U P CUSHIONS Cushions are designed to provide smooth deceleration, external energy absorption and noise reduction, over the last 15º of rotation. Cushions trap fluid at the end of stroke by locking or restricting the discharge port. The trapped fluid is diverted through a small needle valve which generates a back pressure on the discharge side of the piston. This back pressure resists the forces exerted on the internal parts of the rotary actuator, thus causing a slowing of the external mass. IN TERNAL ST ROKE ADJUSTOR & ADJUSTABLE CUSHION The 0-5º internal stroke adjustor and the adjustable cushion are combined into a single option. This design permits the full cushioning effect at any stroke adjustment setting. CAUTION: Cushion needles should be set between one half and one full turn from seated position. Setting should result in continuous speed reduction throughout the cushion length. Needle adjustment is set too far closed when there is an abrupt change in speed as the actuator enters the cushion. Never operate with needle in seated position or unscrewed beyond the point where the seal relief in the thread is visible. CAUTION: Cushion needle adjustment is a crucial factor in achieving optimum cushion performance. If the needle valve setting is too far open, cushion capacity will be reduced, or rendered ineffective; if set too far closed, cushion action will generate shock and pressure spikes in excess of actuator rating. H Y D R A U L I C S E R I E S A D J U S T A B L E C U S H I O N IN TERNAL ST ROKE ADJUSTORS Internal stroke adjustors permit 0-5º of adjustment. A threaded bushing within the end cap is set in position by a hex wrench inserted through the port and locked in place with a set screw. *NOTE: When ordering a double rack model with stroke adjustors it is necessary to order end of stroke adjustors for both cylinders. When only one stroke adjustor is used for end of stroke adjustment on a double rack model the maximum operating pressure must be limited to bar. *NOTE: Cushions and external stroke adjustors are not available on the same cylinder end cap for standard models.

When properly sized and adjusted, cushions may also provide smooth deceleration, external engery absorption and noise reduction. Cushions trap fluid at the end of stroke by blocking or restricting the discharge port. The trapped fluid is diverted through a small needle valve which generates a back pressure on the discharge side of the piston. This back pressure resists the forces exerted on the rack by the propelling action of the actuator and the slowing of external mass which imparts energy into the actuator through the shaft. A check valve is included to bypass the cushion action at the start of rotation in the reverse direction.

Like the air units, setting the stroke adjustment does not affect cushion engagement length. However, the amount of cushion effect is not adjustable in this option. The fixed cushion orifice is sized to absorb the propelling torque developed on the working side of the actuator at speeds of less than 90º/sec and may not be sufficient to adequately stop additional inertial loads imparted through the shaft.

54 A P P L I C A T I O N E X A M P L E S, R O T A R Y M O T I O N E N G I N E E R I N G The torque required to put a load into motion by a rotary actuator is the sum of the static torque, the dynamic torque and the gravitational torque. Static torque is the torque of friction, dynamic torque is the torque required to accelerate to desired speed and gravitational torque is the torque necessary to lift a weight against gravity. It is suggested that an actuator with reserve capacity of at least 20 percent be selected to accommodate variations within the system. ROTATION IN VERTICAL PLANE The maximum torque required to rotate the weight (W) thru an angle Ø in a vertical plane will occur when the arm is horizontal. This torque is determined by the equation: T = Wr. If the arm mass is significant its effect on the torque required must be calculated. As the arm approaches vertical the required torque becomes less because the arm length (r) becomes shorter as a function of the sine of the angle. The torque required at any position can be determined by: T = Wr sin Ø HORIZON TAL ROTATION OF SUPPORTED WEIGHT The previous example does not include any considerations for friction. Friction Torque (T f ) can be determined by the product of the weight (W), the coefficient of friction (C f ) and the bearing radius (r b ). T f = W C f r b Bearing This is important because energy built up during uniform acceleration must be absorbed during deceleration by a build up of back pressure in the actuator cylinder. Since energy in must equal the energy out, if the rotary actuator is used to decelerate the load, any reduction in deceleration time will result in increased back pressure which may be damaging to the rotary actuator and other system components. In all circuits this back pressure must be absorbed into the existing system. Consider that acceleration energy equals torque times the angle of acceleration (T a θ a ). In terms of kinetic energy it is: E k = Jω 2 2 The deceleration torque required to stop the load is kinetic energy divided by the angle of deceleration: T d = Jω 2 2θ d Since deceleration energy must equal acceleration energy (T d θ d =T a θ a ) and actuator pressure is proportional to torque, we can set up a simple example of angular travel and pressure. EXAMPLE: If a load is uniformly accelerated thru 100º rotation at 69 bar, you can determine the deceleration pressure to stop the load in 80º by the following: 100º x 69=Pressure to decelerate=86 bar 80º ANOTHER EXAMPLE: Uniformly accelerate a load thru 165º rotation at 34.5 bar, then stop the motion within the last 15º of rotation: NOTE: (W) should include the weight of the turntable as well as the load. Torque (T f ) required to overcome friction must be added to the acceleration torque (T a ) prior to selecting the proper rotary actuator model. The friction torque can be subtracted from the deceleration torque if desired. HORIZON TAL ROTATION OF UNSUPPORTED WEIGHT The torque (T a ) required to accelerate (rotate) unsupported weight in a horizontal plane can be determined by: T a = J O< Where J = Wr 2 g Angular acceleration (α) is usually uniform and can be determined by: α = (ω 2 - ω 1 ) Where ω= (θ 2 - θ 1 ) (t 2 -t 1 ) (t 2 -t 1 ) CAUTION: See Caution note on Page 31. DECELERATION Deceleration torque is often the least understood and in many cases the most important requirement to be considered. The time required to decelerate the load within a given angle of rotation should usually be longer than the time required to accelerate the same load to a required speed. 165º x 34.5 bar=pressure to decelerate=379 bar 15º Accel.@ 34.5 bar Deceleration pressure of 379 bar to dissipate the kinetic energy during the last 15º of rotation may prove to be destructive to the system. Another example illustrates the use of flow control valves to control output flow. A mass accelerated through 40º at 138 bar, then moving at constant speed for 125º, will generate a destructive deceleration pressure of 368 bar to dissipate the kinetic energy within the last 15º of rotation. 40º x 138=Pressure to decelerate=368 bar 15º Constant Speed 125º 138 bar 379 bar 368 bar In addition, since it is difficult and in many cases impractical to remove system pressure during deceleration, one must consider the torque developed by the system pressure while driving the load through the deceleration distance (rotation) in addition to the kinetic energy already existing. The optional MOOG FLO-TORK built-in cushions are designed to help decelerate the load during the last 15º of rotation. The deceleration pressure should not exceed the rated pressure of the rotary actuator model selected. 54 M O O G F L O - T O R K E N G I N E E R I N G

55 Q U A N T I T I E S A N D F O R M U L A S F O R R O T A R Y M O T I O N TORQUE is a force that produces rotation of a shaft. It is measured by the product of the force (F) and the perpendicular distance from the line of action of the force to the centerline of rotation (r). T = F r ROTATION results when an unbalanced torque acts on a body producing an angular acceleration. The torque to accelerate is the product of the body s moment of inertia about its axis of rotation (J) and the angular acceleration (α). T = J α MOMEN T OF IN TERIA of a body is determined by the distribution of its mass about the axis of rotation. It tends to resist any change in angular velocity. J = mr 2 See table page 56 ANGULAR ACCELERATION is the rate of change of angular velocity and is expressed in radians per second per second. If angular velocity changes from ω O at time O to ω t at time t in time (t), the average angular acceleration is: α = ω t - ω O t ANGULAR VELOCITY is the rate of angular rotation about an axis and is expressed in radians per second. If a body moves through a rotation of θ radians in a time of t seconds, the average angular velocity is: ω= θ t ANGULAR ROTATION is the arc traveled in rotary motion and can be expressed in degrees, revolutions or radians. One radian is the angle defined from the center of a circle by an arc that is equal in length to the radius. r -Arc length equal to radius 1 revolution = = 2π radians 1 radian = KINETIC ENERGY is the energy of a mass in motion. It is a function of the moment of inertia (J) and the square of the angular velocity (ω) expressed as: E k = 1/2 J ω 2 EQUATIONS FOR ANGULAR MOTION are analogous to those for linear motion: v = at s = 1/2at 2 v 2 = 2as ω = αt θ=1/2αt 2 ω 2 = 2αθ If v o and ω o denote the initial linear and angular velocity then v = v o + at s = v o t + 1/2at 2 v 2 = v 2 o + 2as ω = ω o + αt θ=ω o t + 1/2αt 2 ω 2 = ω 2 o + 2αθ ANALOGOUS LINEAR & ANGULAR QUAN TITIES Linear Displacements s s = θr Angular Displacement θ Linear Velocity v v = ωr Angular Velocity ω Linear Acceleration a a = αr Angular Acceleration α Mass (Inertia) m J = mr 2 Moment of Inertia J Force F T = Fr Torque T Linear: F = ma E k = 1/2mv 2 Work = Fs Power = Fv Angular: T = Jα E k = 1/2Jω 2 Work = Tθ Power = Tω DEFINITIONS Symbol Units of Measure a = Linear Acceleration m/s 2 C f = Friction Coefficient dimensionless C T = Torque Coefficient Nm/bar E c = Cushion Energy Joules E f = Friction Energy Joules E g = Gravitational Energy Joules E k = Kinetic Energy Joules E p = Propelling Energy Joules E T = Total Energy Joules F = Force N g = Acceleration due to Gravity 9.81 m/s 2 J = Moment of Inertia kg (m) 2 m = Mass = W/g kg P = Pressure bar r = Radius m r a = Radius Arm Length m r b = Radius of Bearing m s = Linear Displacement m T = Torque Nm T a = Torque of Acceleration Nm T d = Torque of Deceleration Nm T f = Torque of Friction Nm T p = Torque of Propulsion Nm t = Time sec v = Linear Velocity m/s W = Weight N α = Angular Acceleration rad/sec 2 θ = Angular Displacement rad θ a = Angle of Acceleration rad θ d = Angle of Deceleration rad Ø = Angle of Arm to Vertical deg Ø = Average Angle from Vertical deg ω = Angular Velocity rad/sec E N G I N E E R I N G E N G I N E E R I N G M O O G F L O - T O R K 55

Setting should result in continuous speed reduction throughout the cushion length. Needle adjustment is set too far closed when there is an abrupt change in speed as the actuator enters the cushion. Never operate with needle in seated position or unscrewed beyond the point where seal relief in the thread is visible. CAUTION: Cushion needle adjustment is a crucial factor in achieving optimum cushion performance. If the needle valve setting is too far open, cushion capacity will be reduced or rendered ineffective; if set too far closed, cushion action will generate shock and pressure spikes in excess of actuator rating. 56 M O O G F L O - T O R K E N G I N E E R I N G

57 C U S H I O N C A P A C I T Y A N D S I Z I N G High rotational velocity and/or large mass in rotary motion can cause damaging impact at the end of stroke. Deceleration and absorption of rotating system energy can be achieved with cushions, external shock absorbers or fluid circuit devices which reduce speed as the actuator approaches the end of travel. Cushions are the simplest design alternative, but consideration must be given to the cushion energy absorption capacity. Exceeding rated cushion capacity can reduce actuator life or result in severe actuator damage. To determine if a cushion is suitable for the application, calculate the total energy that must be absorbed and compare with the cushion capacity rating. ENERGY OF APPLICATION E k = Energy of mass in motion (kinetic energy) E k = 1/2 J ω 2 E p = Propelling energy of actuator E p = P p C t θ d E g = Gravitational energy of lifting or lowering weight E g = Wr a θ d sinø Total Energy, where: E t = E k + E p ± E g E g is added if weight is falling or E g is subtracted if weight is rising NOTE: If weight is rotating in horizontal plane, the gravitational energy is zero. HORIZON TAL ROTATIONAL DECELERATION Two 22.6 kg parts are positioned diametrically opposed on a 68 kg lb rotary transfer table which swings through 180º in a horizontal plane. The table radius is 1.27 m in and the radius to the parts is 1.02 m Rotational velocity of the table as it enters the cushion deceleration arc is 80º/sec or ( ) 1.40 rad/sec. A model 3700 actuator operating at 103 bar has been selected to propel the load. VERTICAL ROTATIONAL DECELERATION A material handling rollover mechanism transfers a 45 kg machine part through 180º in a vertical plane from a 9 o clock to a 3 o clock position. The radius arm to the part grippers is 1.02 m and the effective weight and radius of the arms and grippers can be approximated by two 1.02 m long rods weighing 32 kg a piece. Rotational velocity of the mechanism as it enters the cushion deceleration arc is 40º/sec or ( ) 0.70 rad/sec. A Model actuator operating at 138 bar has been selected to propel the load. KINETIC ENERGY E k = 1/2 J ω 2 Moment of Inertia J = J arm + J load J arm = 2 M a r 2 a = 2 (32 kg) (1.02 m) 2 = 22.2 kg m J load = M I r 2 I = (45 kg) (1.02 m) 2 = 47 kg m 2 J = J arm + J load = = 69.2 kg m 2 E k = 1/2 J ω 2 = 1/2 (69.2 kg m 2 ) (.70 rad/sec) 2 = 16.9 kg m 2 = 16.9 Joules s 2 PROPELLING ENERGY E p = P p C t θ d Torque Factor (C t ) for Model (8.19 Nm/bar) Deceleration Arc (θ d ) for Model (.34 rad) E p =P p C t θ d = (138 bar) (8.19 Nm/bar) (.34 rad) = 384 Joules GRAVITATIONAL ENERGY E g = Wr a θ d sinø Wr a = 9.81 m [(45 kg)(1.02 m) + 2(32 kg)(1/2)(1.02m)] = 770 Nm s 2 Deceleration Arc (Ø d ) for Model (0.34 rad or 19.6 o ) Ø=1/2 (Ø enter +Ø end ) E N G I N E E R I N G KINETIC ENERGY E k = 1/2 J ω 2 Moment of Inertia J = J table + J load J table = M t r 2 t = (68 kg) (1.27 m) 2 = 54.8 kg m J load = M I r 2 I = ( kg) (1.02 m) 2 = 47 kg m 2 J = J table + J load = = kg m 2 Ek = 1/2 J ω 2 = 1/2 (101.8 kg m 2 ) (1.40 rad/sec) 2 = 99.7 kgm 2 = 99.7 Joules s 2 PROPELLING ENERGY E p = P p C t θ d Torque Factor (C t ) for Model 3700 (2.02 Nm/bar) Deceleration Arc (θ d ) for Model 3700 (.33 radians) E p = P p C t θ d = (103.4 bar) (2.02 Nm/bar) (0.33 radians) = 68.9 Joules GRAVITATIONAL ENERGY E g = 0 for horizontal rotation TOTAL ENERGY E t = E k + E p ± E g E t = Nm = Joules Total energy to be absorbed in the example is Joules. The cushion capacity of Model 3700 when properly adjusted is Joules. This is adequate to meet the deceleration requirement. Ø enter =Ø end - θ d = 90 o o = 70.4 o Ø=1/2 (70.4 o + 90 o ) = 80.2 o Ø end = 90 3 o clock sin Ø =.99 E g = Wr a θ d sinø = (770 Nm)(.34 rad)(.99) = 259 Joules Ø enter = 70.4 o θd =19.6o TOTAL ENERGY E t = E k + E p ± E g E t = Nm = Joules Total energy to be absorbed in the example is Joules. The cushion capacity of Model is 711 Joules. This is adequate to meet the deceleration requirement. When the energy developed exceeds the capacity of the cushion, consider the following: l REDUCE WEIGHT OF OBJECT IN MOTION l REDUCE ROTATIONAL VELOCITY l EMPLOY EXTERNAL SHOCK ABSORBERS l ADD PROPORTIONAL HYDRAULICS TO THE CIRCUIT TO REDUCE PROPELLING ENERGY DURING DECELERATION. CAUTION: Cushion needle adjustment is a crucial factor in achieving optimum cushion performance. If the needle valve setting is too far open, cushion capacity will be reduced or rendered ineffective; if set too tight, cushion action will generate shock and pressure spikes in excess of actuator rating.

58 L I N E A R D R I V E E N G I N E E R I N G LINEAR DRIVE WITH MOOG FLO-TORK ROTARY ACTUATORS USING HARMONIC MOTION The advantages of using rotary actuators, combined with harmonic-motion-producing linkages, compared to the straight line cylinders, are derived from the principle of converting a constant speed rotating motion to a sinusoidal (sine-wave) motion which produces maximum linear force where needed for acceleration... and just the opposite force for deceleration and stopping the load. Meanwhile, you develop maximum linear speed during the middle of the 180º rotation cycle. Acceleration control is easy to achieve and usually is limited only by the available hydraulic or pneumatic power. Deceleration is usually the big problem and the speed of any reciprocating or oscillating motion is normally limited by the ability to control deceleration. Deceleration valves are expensive, difficult to field-adjust and susceptible to tampering and to malfunction from contaminated oil or air. A simple flow control valve to maintain constant speed of the rotary actuator can, when combined with harmonic linkage, decelerate the load smoothly to rest. HIGH SPEED -SMOOTH SPEED CON T ROL Controlled acceleration and deceleration... with the MOOG FLO-TORK rotary actuator rotating at a constant speed. You can go faster and smoother using rotary actuators than with any other method. GEN TLE ACCELERATION You have the maximum mechanical advantage where you need it... at the beginning of the travel. Force arrow shows maximum force in the direction of start-up to get you started faster. SPEED Maximum velocity is when the load is halfway to its destination. Smooth acceleration to that point... then smooth deceleration. GEN TLE DECELERATION You have the maximum mechanical advantage where you need it... at the end of the travel. Deceleration is a mirror reflection of acceleration and the load will be slowed down by the rotary actuator automatically. 58 M O O G F L O - T O R K E N G I N E E R I N G

59 F T H Y D R A O L I C Dim D BEARING LOAD CAPACITIES BEARING LOAD CAPACITIES - MOOG FLO-TORK hydraulic rotary actuator bearings are sized to accept external loads. This feature often allows the shaft to be mounted directly to the rotary actuator without flexible couplings and outboard bearings, utilizing the MOOG FLO-TORK actuator as the bearing. MAXIMUM EXTERNAL RADIAL LOAD L MODEL (mm) 900/ / / / / MODEL BA R N N N N N N N N N N MAXIMUM EXTERNAL THRUST LOAD T E N G I N E E R I N G *CAUTION: L is the maximum allowable external radial load at the maximum distance D (distance from housing to middle of keyway as shown on the chart as dimension D). To find L match the model and maximum operating pressure to find the maximum external radial load L on the rotary actuator. T is the maximum allowable external thrust load. To find T, match the model and maximum operating pressure to find the maximum thrust load on the rotary actuator. For combined radial and thrust loads consult factory. SPECIAL CONSIDERATIONS 1. SPECIAL SYSTEM DESIGN consideration must be given to applications that involve high speed rotation, high cycle life, eccentric external loading conditions, or when the actuator maximum allowable pressure is exceeded. These design considerations may include internal or external shock absorbers, external controlled stops, special material or hardness treatment for actuator internal parts and special hydraulic system controls. 2. CUSHIONS are available on MOOG FLO-TORK air and hydraulic rotary actuators. MOOG FLO-TORK s adjustable cushions will help absorb deceleration forces smoothly through the last 15º of rotation. 3. POSITION HOLDING OR BRAKING is possible by using holding valves or pilot operated checks. The MOOG FLO-TORK rotary actuator provides positive holding when used with good quality holding or locking valves. 4. SPEED CONTROL can be accomplished by controlling the fluid being exhausted from the rotary actuator (meter-out). Meter-out speed control is preferred to meter-in control, as it prevents runaway or cavitation. Consult factory for rotational speeds exceeding 90º in one (1) second. 5. CROSS-OVER RELIEF VALVES may be required to limit shock pressures and protect components in the system. 6. SYSTEM CLEANLINESS-The life and reliability of rotary actuators as well as other fluid power components are largely dependent upon system cleanliness. The best service life can be obtained by: A) Complete flushing of each segment of the hydraulic circuit before connecting to the rotary actuator. B) Providing suction line filters of 100 mesh screen or finer and pressure line filters of 25 micron nominal or finer. 7. SLOW ROTATION - The enclosed gear cases of MOOG FLO-TORK hydraulic rotary actuators are filled sufficiently with gear oil to lubricate the moving parts by immersion and splashing. In applications with slow rotation caution must be taken to insure that lubricant reaches upper gear components. 8. HOLLOW SHAFT - A high strength steel shaft with full length key engagement is recommended to mate with MOOG FLO-TORK s high strength hollow shaft pinion. SPECIAL DESIGNS The following are examples of MOOG FLO-TORK designs to satisfy special customer applications: A) THREE POSITION ACTUATORS B) AIR-OIL ACTUATORS FOR AIR OPERATIONS WITH OIL SPEED CONTROL C) NON TIE-ROD DESIGN D) SPRING RETURN E) MANIFOLD PIPING F) BUILT-IN CONTROL VALVES For special designs please forward a completed Application Specification Guide to MOOG FLO-TORK, Inc.
