It is the number of complete cycles in time that an actuator can perform. It is represented by Lc. It is the load that corresponds to the average of the different loads during one cycle. It is represented by m. The load can vary during the cycle and the distance the load is applied for varies (S). In order to calculate the average load the following formula is used: m = 1 x S1 2 x S2 +... Where: 1, 2,... = onstant load in N, for travel S1, S2,... S1 + S2 +... S = Travel in mm. The life of a screw in complete cycles, i.e. both directions, will be primarily determined by the screw s pitch, the travel, the dynamic load and the average load. ) The life of a ball-screw can be calculated from the dynamic load and the travel. Where: Lc = Life in complete cycles (one cycle is defined as movement in both directions) P Screw pitch in mm. S Travel in mm. = ynamic load of the screw in N. (Actuator size: F- =.000N; F- = 14.000N; F- = 24.000N; F- = 42.000N; F- = 78.000N) m = onstant average load in N. An M1 F- with a stroke of 0 mm a pitch of mm and a load of.000n in one direction and of 2.000N in the other. We calculate the average load that will be applied during one cycle and then the life of the screw in cycles. These calculations use the following average load formula: m = 1 x S1 2 x S2 +... S1 + S2 +... m = 2.000 x 0.000 x 0 0 + 0 = 2.97N Knowing the average load the life can be calculated, using the following formula: ( Lc = 0.000 S x P x m) ( Lc = 0.000.000 x x 14.000 2.97) = 1.0.000 cycles The electromechanical linear actuators require a similar lubrication to that used for ball bearings. In normal working conditions, the actuators should be greased between 800 and 2.000 operating hours (factors such as the load, the number of cycles and the screws revolutions must be taken into account). The unit is delivered lubricated with KLUBR ISOFLX TOPAS NLGI grease type 2, (IN ). When using the unit at high speeds choose type 1, and for heavy loads type. ontinuous lubrication is not advised because the alternating motion deposits too much grease on the screw filling the spindle tube and reducing the available stroke together. There will also be an increase in temperature. Precision Technology
GNRAL SIGNAION THNIAL ATA OMMNTS This general data is applicable to all the electromechanical actuators, specific technical data is shown for each model. UTY YL MAXIMUN LOA ALLOWABL The duty cycle can be defined as the relation between the running time, under load, and the total cycle time. Fc = uty cycle = T T + R x 0 Where: T = On-time with load. R = Idle time. T + R = Total cycle time. The maximun load allowable is defined as the load advised by the manufacturer. It should not be exceeded as the life of the units will be adversly effected. BASI LMNT OF MOL UTY YL IAGRAM The screw is the basic drive element and can be either ball-screw or trapezoidal. epending on the load applied the following graphs show the maximum duty cycle. TRAPZOIAL SRW Load 0% BALL-SRW Load 0% % % % 0 % uty cycle % 0 % uty cycle RLATIONSHIP BTWN LOA AN UTY YL The maximum allowable load depends on the duty cycle. The load should be reduced when the duty cycles increases. If the advised duty is exceeded the actuator can be damaged. Precision Technology 76

For this load we apply the appropriate percentage to the maximum dynamic load. If we utilise the basic actuator F-, we have a maximum dynamic load of.000n. Maximum load =.000N, (each basic model has a specific maximum load see page 11) Therefore the maximum allowable load is 0.9 x.000n = 9.000N T T + R x 0 + x 0 = 4 % FINITION OF TH RQUIR TORQU The required torque is defined as the force required in order to move actuator under load. TH RQUIR In order to calculate the required torque the following formula will be used: TORQU ALULATION P The screw s pitch in mm. Torque = P x F F Force required in N. 2.000 x x = The efficiency constant; 0.8 for the ball-screw and 0.2 for the trapezoidal screw. XAMPL OF A TORQU ALULATION SLTION RITRIA An electromechanical actuator F- with a ball screw having a pitch of has to move a load of 0 Kg. in a vertical plane. What would be the required torque?. Force = M x g = 0 x 9.81 = 2.0N Torque = 2.0 x 2.000 x x 0.8 = 2.6 Nm ( = 0.8 because it is a ball screw) We must take into account the fact that with the same actuator, for example with a screw actuator of, several different speeds can be achieved dependant on the screw s pitch (in this case it could be of, or mm/revolution). qually the gear ratio of the gear box affects the achievable travel speed.
