ROTARY MOTION CONTROL

ROTARY MOTION CONTROL Technical Data Sheet Nexen Mechanical Torque Limiter Family PMT / PMK / PMC 2TC 2CC ECC PCC Mechanical Torque Limiter The trend in industry is to design and incorporate more automation into production processes. Machines are becoming more accurate, requiring a higher degree of precision. They are becoming faster, using servo and DC drive technology, and they are more rigid to withstand the dynamic loads necessary to increase capacity and productivity. Torque overloads caused by material jams, operator error, or a whole host of unforeseen reasons pose a significant threat to machine downtime. Machine downtime in an automated production environment is very costly. Broken components, costly technicians, and long lead times for custom components can make the difference between operating profitably or not. The use of a patented torque limiter will isolate the driving from the driven elements within a matter of milliseconds, once the torque reaches a preset overload value. Features Precise overload protection Absolutely backlash-free and torsionally rigid Compact, simple design Disengagement detection is achieved through indexing ring movement Low residual friction following disengagement Low moment of inertia Disengagement within milliseconds Double bearing support of pulley/sprocket

Overview Order using model descriptions only 1 2 MTLXXX - XXX - XX - XXX-XXX - XX/XXX - XXX - XX - XXX - X FIELD 1: Specify MTL size 1,, 0, 10, 0, 0, 00, 00, 100 or 0 9 7 FIELD 2: Select the type of MTL PMT (Pilot Mount/ Tapered clamping hubs) lock the torque limiter to the shaft with a series of cap screws that are alternately and evenly tightened. PMK (Pilot Mount/ Keyed bore) do not have set screws to retain the unit on the shaft. Use shaft collars to fix position of the MTL on the shaft. Setscrews are not an option with this design. PMC (Pilot Mount/ Clamp Collar) lock the torque limiter to the shaft with a single clamp collar. 2CC: Coupling with two clamp collars and a integral, bellows coupling 2TC: Coupling with two Tapered clamping hubs and a integral, bellows coupling PCC: Coupling with two clamp collars/and a conical, press-fit insert. The unit dis-mounts without loosening the collars ECC: Coupling with two clamp collars with an elastomer (spider) coupling FIELD : Select the interface function SP (Single Position) most coonly used, advantage is automatic re-engagement, resets at a single point every 0 degrees. Overloads are sensed with a proximity sensor. MP (Multi-Position) applications include slow speed, single directional shafts like those used on conveyors or mixers. Overloads are sensed with a proximity sensor. FD interfaces are used where a proximity sensor is not an option. Low residual friction of the full disengagement version allows for multiple revolutions of the clutch to take place with minimal wear. Re-engagement is not automatic; the spring must be manually moved into position after an overload occurs. The Full Disengagement MTL re-engages manually every 0º (six positions). Other positions available on request. FIELD : Specify the bore size; refer to the maximum bores sizes in the selection chart. Specify a bore diameter for both ends of the coupling. (Example A: 1 thru bore: 1.000 ) (Example B: 2 thru bore: 2MM ) (Example C: 1 & 1.2 bores: 1.000-1. ) FIELD : Specify the torque range; multiple torque ranges are shown for each model size. Select the torque range that provides the trip-torque in the middle of the range to allow for torque setting adjustment either up or down. Always list torque range in newton meters. Single Position Multi-Position FIELD : Specify the trip-torque setting. This is the torque level where the MTL disengages to protect the components in the drive train. Always list trip-torque in newton meters. FIELD 7: Specify the unit finish if non-standard. Standard material is black oxide steel. Optional material is stainless steel, designated as SS in this field. Note: Stainless steel MTL s are three times the cost of a standard unit. FIELD : Specify the overall length for billows couplings (re: dimension A in the product catalog). The shortest overall length given in the catalog for billows type couplings provides more lateral and radial stiffness than the longest overall length. The longest overall length provides more misalignment than the shortest overall length. FIELD 9: Specify the optional seal for the actuation ring. The seal provides protection from dirt and liquid contamination and is appropriate for food service and light wash-down environments. The seal also contains the bearing grease in the MTL. See rear cover of this document for MTL Facts. (Example: S for seal, nothing for no seal) 2 Full Disengagement

The adjustment range (min/max) is also marked on the adjustment nut (1). The customer can adjust the disengagement torque as long as it falls into the range () indicated on the adjustment nut. The adjustment range may not be altered during setting. To adjust the disengagement torque, loosen the locking screws () and rotate the adjustment ring using a spanner wrench to the desired new setting. Tighten the three locking screws () and test the torque limiter. All size 10 MTL units are hand adjusted.

Product Selection Based on Torque Requirements As a rule, torque limiters are selected according to the required disengagement torque. This rating must be greater than the torque necessary for normal machine operation. The necessary disengagement torque is determined in accordance with the drive specifications. The following calculations have proven themselves as rule of thumb solutions. Disengagement Torque or Start-up Torque Without a Load T KN = Rated Torque of the Torque Limiter T AS = Peak Torque of Motor T KN = Rated Torque of the Torque Limiter P AN = Drive Power (kw) N = Speed of Drive (RPM) T KN = Rated Torque of the Torque Limiter = Angular Acceleration S A = Load Factor S A = 1 (Uniform Load) S A = 2 (Non-Uniform Load) S A = (Jerky Load) Values for S A = 2 - are usual for servo drives on machine tools Start-up Torque With a Load t = Acceleration Time (s) = Angular Speed In (s- 1 ) n = Speed of Drive (RPM) J L = Moment of Inertia on Load Side (kgm 2 ) J A = Moment of Inertia on Drive Side (kgm 2 ) T AS = Peak Torque of Motor T AN = Rated Torque of the Torque Limiter = Angular Acceleration S A = Load Factor S A = 1 (Uniform Load) S A = 2 (Non-Uniform Load) S A = (Jerky Load) Values for S A = 2 - are usual for servo drives on machine tools. t = Acceleration Time (s) = Angular Speed In (s- 1 ) n = Speed of Drive (RPM) J L = Moment of Inertia on Load Side (kgm 2 ) T AN = Load Torque J A = Moment of Inertia on Drive Side (kgm 2 ) T AS = Peak Torque of Motor Machine Tool - Feed Force Torque Spindle Drive Timing Belt Drive T AN = Load Torque S = Spindle Pitch F V = Feed Force = Spindle Efficiency T AN = Load Torque d o = Sprocket Diameter F V = Feed Force () (N) () (N) Spindle Motor Timing Belt Drive Conversion Formulas kw (kilowatt) = 0.7 x hp Nm (Newton-meter) = in-lbs /.

THE NEXEN ADVANTAE The trend in industry is to design and incorporate more automation into production processes. Machines are becoming more accurate, requiring a higher degree of precision. Machine downtime in an automated production environment is very costly. Broken components, expensive technicians, and long lead times for custom components. The use of a Nexen Mechanical Torque Limiter isolates the driving from the driven elements within a matter of milliseconds. This can be the difference between operating profitably or not. Features Adjustment range engraved on the outer diameter Actual values marked rather than percentages Adjustable without removal from the application Patented preload for zero backlash Small, guided actuation ring for fast reaction Double bearing support fo pulley / sprocket Large bores possible MTL Facts Always use Proximity Sensor #1 with MTL applications Disengagement response time is 1- msec Single position and multi position MTL s will try to re-engage if the drive is not shut down. It is always best to have a quick and automatic reengagement because MTL s can show wear that is significant enough to cause re-adjustment or replacement after 1000 disengagements. Special units available for high temperature operation up to 00 F MTL s are tuned by adjusting the spring height. CW rotation decreases the spring force and CCW rotation increases the spring force. MTL s are coonly set in the middle of the torque range. A spanner wrench is available for torque adjustment for sizes 1-0. Model MTL10 is hand adjusted. No wrench needed.
