helix_angle¶
- property WormWheel.helix_angle: Angle
Helix angle of the worm wheel. It must be an instance of
Angle.The maximum allowable value of helix angle depends on the
pressure_angle.Once set at the worm gear instantiation, it cannot be changed afterward.
Returns¶
AngleThe helix angle of the worm wheel.
Raises
TypeErrorIf
helix_angleis not an instance ofAngle.ValueErrorIf
helix_angleis greater than the maximum allowable helix angle, depending onpressure_anglevalue.
