Generally, the rotation stopping end of the motor spindle 3 is generally non-circular, and the rotation stopping groove is matched with the rotation stopping end, so that the rotation stopping end cannot rotate relative to the rotation stopping groove.
The guiding device is mounted on the mounting base 1 and guides the axial movement of the moving unit 2, where the axial direction refers to the axial direction of the motor spindle 3, and is also the axial direction of the rotation stopping groove, such as a D-shaped groove. Meanwhile, the guide device should be capable of limiting rotation to prevent the movement unit 2 from rotating relative to the mounting base 1, that is, when the guide device is used, the movement unit 2 is prevented from rotating relative to the motor base, and then the motor spindle 3 is prevented from rotating relative to the motor base through the rotation stopping groove.
Wherein catch bar 4 passes through threaded connection with mounting base 1, and the axis direction of this screw thread is unanimous with guider direction, is parallel with the axis of motor spindle 3 or coaxial setting promptly, and one end links to each other with motion unit 2, so when catch bar 4 rotates relative mounting base 1, because threaded connection's relation, so catch bar 4 moves along the screw thread axial, and the axial promotion motion unit 2 along motor spindle 3 moves promptly, establish the end of splining at motor spindle 3 with the groove cover that splines that promotes motion unit 2, and then play the effect of splining.
When the hand-rotating mechanical motor brake is applied, the mounting base 1 and the motor base are relatively fixed, and the rotation stopping groove of the moving unit 2 is aligned with the rotation stopping end of the motor spindle 3.
