(I'm not sure where this would be on topic)
I need something to help drive a wheel. A bearing will be stuck on a shaft that will be connected to a DC motor. The shaft cannot be allowed to apply reverse force on the motor. I can explain further if necessary.
What I want is something like a ratcheting wrench uses. Apparently there are ratcheting devices to drive the wheel of a bicycle but what I've seen of those would be too large. It needs to be no more than about 1 inch maximum diameter.
So, is there such a thing as a ratcheting bearing? Something similar?
What I mean by "ratcheting" is that the bearing will turn freely in one direction but won't turn in the other direction.
By the way. I recall a clicking sound made by some geared bicycles when coasting, was that made by a ratcheting device? Just curious.
