Rack and Pinion Mates
With rack and pinion mates, linear translation of one component (the
rack) causes circular rotation in another component (the pinion), and
vice versa.
You can mate any two components to have this
type of movement relative to each other. The components do not need to
have gear teeth.
Similar to other mate types, rack and pinion mates do not prevent interference
or collisions between components. To prevent interference, use Collision Detection or Interference
Detection.
To add a rack and pinion mate:
Click Mate
(Assembly toolbar) or Insert,
Mate.
In the PropertyManager,
under Mechanical Mates, click
Rack Pinion
.
Under Mate Selections:
For Rack,
select a linear edge, sketch line, centerline, axis, or cylinder.
For Pinion/Gear,
select a cylindrical face, circular or arc edge, sketch circle or arc,
axis, or revolved surface.
Under Mechanical
Mates:
For each full rotation of the pinion, the
rack translates a distance equal to
multiplied by the
pinion diameter. You can specify either the diameter or the distance by
selecting one of the following:
Pinion pitch
diameter. The diameter of the selected pinion appears in the box.
Rack travel/revolution.
The diameter of the selected pinion, multiplied by
, appears
in the box.
You can override the value
in the box. To revert to the default value, delete the override value.
The background color of the box is white for the default value, and yellow
for the override value.
