A polyclutch slipper controls torque for intermittent, continuous or overload slip. It will drive in both directions, slip when torque setting is reached, and resume driving as the load is reduced. Slippers are excellent as continuous drag brakes, protection against accidental or intentional overloads, for "soft starts", slip at end of stroke etc. Torque control in one direction only can be provided by combining a Slipper with a POLYCLUTCH Hub Pak.
The Slipper is a small precision device containing a number of brass plates interfaced with an improved long life friction material. Soft springs maintain pressure on the friction members, assuring constant torque. An adjacent member of your mechanism can often be used as the Slipper housing. Backlash of 6° is standard; 2° backlash available on request. Adjustable Torque: For shaft to shaft coupling. Set screw housings in both housing and cartridge.
Fixed torque clutches available (shortens length and torque - factory pre-set). P.O.A. Example: The SAS20-6 can dissipate 6 Watts continuously. This translates to:
| in lbs |
@ rpm |
@ % slip |
% slip means within 5 mins. max. time period, e.g. 25%=25s of slip, 75s of rest, not 25/75 mins. As a rule, slip speed in rpm x torque in in-lbs x duty cycle in % x 0.011 = Watts |
