Re: Window motor to toughbox?

We've attached a window motor to a CIMplebox for our arm, but we had to machine a keyed adapter shaft to go from the plastic window motor adapter to the small gear. It seems to be working quite well so far; the gear reduction produces an ideal rate of rotation and sufficient torque to lift our manipulator.

A chain-based system would work, but you still have to find a way to attach the sprocket to a gear. The KOP sprockets are just too narrow to fit over the adapter without modification.

Either system would require a lot of structural support, since the window motor adapter isn't firmly attached to the motor axle. Bearings on the axle are also a good idea, to prevent cantilevering.

Also, the metal shaft doesn't rotate, so cutting away the toothed plastic bit won't do you any good.
