(...) Using a unit of energy for torque would be very strange. You get an energy if you turn s.th. against a torque through some angle (expressed in radians, I think). Angles have no unit (or just 1), hence the units of torque and energy are equal. (...) (25 years ago, 5-Apr-01, to lugnet.robotics.rcx)

Ok, this is called a "Slip Gear" or "Torque Gear" It is used to prevent over rotation by means of an internal clutch, the 2.5 - 5.0 NCM I belive means the range of operable force applied before the clutch disengages.

I think it is called a "clutch" gear. It is used in place of a regular gear when the gear train that it is in may get locked up. It will then slip, which will prevent damage to the motor. I imagine it has other uses too... -HTH -Andy Lynch ----- (...) (25 years ago, 3-Apr-01, to lugnet.robotics.rcx)
