Screw Mate

A Screw mate constrains two components to be concentric, and also adds a pitch relationship between the rotation of one component and the translation of the other component.

Translation of one component along the axis causes rotation of the other component according to the pitch relationship. Likewise, rotation of one component causes translation of the other component.

Similar to other mate types, screw mates do not prevent interference or collisions between components. To prevent interference, use Collision Detection or Interference Detection.

To add a screw mate:

  1. Click Mate (Assembly toolbar) or Insert > Mate.
  2. In the PropertyManager, on the Mechanical tab, click Screw .
  3. Under Mate Selections, select the rotation axes on the two components for Entities to Mate .
  4. Under Mate Type:
    Option Description
    Revolutions/length_unit Specifies the number of revolutions of one component for each length unit the other component translates.

    Click Tools > Options > Document Properties > Units to specify the document's unit of length.

    Distance/revolution Specifies the distance that one component translates for each revolution of the other component.
    Reverse Changes the direction of movement of the components relative to each other.
  5. Click .
