What is this mehanism called? 1

[ask34]

Does anyone know what this mechanism is called? The mechanism is used in cordless drills to prevent rotation when you tighten the chuck.

I am trying to find any design guidelines for this mechanism.

This one below I removed from a Xiaomi Wowstick electric screwdriver. The parts seem to be sintered or metal injection molded.

- a cam clutch
- a sprag clutch

Looks like what I call a "one-way bearing". PIC Design calls it a Roller Clutch.

I've used them successfully on a couple projects.

Roller clutch it is... from my woodworking shop, it's the same principle as a pin mandrel.
