3 jaw chuck design

[Anonymous]

Hi ,does anyone have detailed design drawings of a typical 3 jaw chuck including the spiral scroll wheel and the matching teeth on the underside of each jaw ?? the spiral scroll seems easy to draw and extrude but i cannot get the jaw teeth to mate properly when using joints thanks Alan h.

There are a few models on GrabCad. 

Contact set would be the usual way of animating it, but they are notoriously bad. 

You could try a Slider plus Revolute joint with a Motion link between them.  That would probably need a few hidden bodies to make it work.
