Rack and Pinion Assembly Testrig

This example models a gear and a toothed bar (rack). The necessary blocks for the rack and pinion assembly are contained in a masked subsystem with the key parameters exposed in a dialog box.

Rack and Pinion Assembly Constraints Subsystem

The Rack and Pinion Constraint requires that the rest of the mechanism hold the two frames to which it is connected in alignment. This subsystem has the necessary constraints and parameterized Rigid Transform to hold the frames in the right position and orientation.
