Hello! There is a part in my RIS set which i have never used. Nor can I think of what it could be used for, or describe it without using words like "weird" and "what the". It's a thick white gear, 1 stud wide by three studs in diameter. One one (...) (23 years ago, 2-Apr-01, to lugnet.robotics.rcx)

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 ----- (...) (23 years ago, 3-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. Nano Centemeter of force. In (...) (23 years ago, 3-Apr-01, to lugnet.robotics.rcx)

(...) Actually it rotates separately only above a certain torque (if you don't know what torque is, think force), that's the 2.5 - 5.0 Ncm mentioned on the inscription. You can use it to prevent damage to your model when your gear train is stalled. (...) (23 years ago, 3-Apr-01, to lugnet.robotics.rcx)

Oh ya, and I used one in the Neck of the Hexapod-armature. So when the neck moved all the way to the Right or Left, the slip gear kicked in and it would'nt break it's own neck. (...) (23 years ago, 3-Apr-01, to lugnet.robotics.rcx)

Don't punish yourself! At least you rendered the symbols from the gear correctly. There are at least four errors in the message I was responding to: (1) confusing the prefix n for nano with the unit symbol N for newton; (2) attaching two prefixes (...)

(...) 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. (...) (23 years ago, 5-Apr-01, to lugnet.robotics.rcx)
