Any suggestions for a simple clutch to protect an output gear from self destruction? A gearmotor can generate 2-3 times the published stall torque depending on the dynamics of the system.
My preference is limit switches in this electrical actuator, but the customer sometimes dictates the config. Another approach is a current limiter, which creates high resistance at overload. Upon removing the voltage, the current limiter quickly resets. The current limiter is not an option here because there is one already: slow acting and rated at high current.
- Gear on shaft with collar; belleville spring behind it with adj nut. A little complex but compact.
- A one way ratchet clutch made from plastic. The tapered fingers were acetal. A two way clutch could be made the same way by changing 90 deg stops to 45 deg.
- USA Tolerance Rings (dot com) is showing a tolerance ring for limited slip gears on shafts. The mfr says that it has to be developed on an individual basis.
Any other ideas for simple clutches?

RE: Gearmotor Clutch to protect output gear
output of the motor? Is it hydraulic,
electric or ? I think this would be
a cheaper solution.
