Worm Gear Constraints and CAD Parts

This example models a worm gear assembly. The worm and gear are STEP files exported from a CAD system. Two Revolute Joints and a Worm Gear Constraint constrain the parts for the correct kinematic behavior.



Worm Gear Assembly Constraints Subsystem

The Worm Gear 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.
