Brake switches between on-position and releasing on-position, and in the first braking parts and the second braking parts a braking parts are set
There is the axially extending axial projection along central axis, another braking parts is provided with accommodation space, wherein, under on-position,
Axial projection is located in accommodation space and forms circumferential spacing cooperation；In the case where releasing on-position, axial projection and accommodation space
Separate to release circumferential spacing cooperation.
In the schematical embodiment, central axis is the axis of motor shaft 1, and the first braking parts are fixedly installed on electricity
To realize rotatably arranged with and the second braking parts un-rotatably set in the circumferential relative to central axis on arbor 1
For being acted under the driving of drive device 2 in first braking parts so as to which the rotation of limiting motor axle 1 is braked to realize.Second
It is to be set by a braking parts in the first braking parts and the second braking parts in that braking parts, which are acted in the first braking parts,
The axially extending axial projection of mandrel line, what another braking parts set accommodation space to realize.If the first braking parts are set
Axial projection, then the second braking parts set accommodation space, if the first braking parts set accommodation space, the second braking parts set axle
To projection.
Under the driving effect of drive device 2, when axial projection is located at accommodation space, axial projection and accommodation space
So as to form circumferential spacing cooperation, the axial rotation of motor shaft 1 is limited peripheral material contact, so as to realize braking；Work as axial direction
When projection separates with accommodation space, axial projection does not contact with the peripheral entity of accommodation space to be come so as to release circumferential spacing cooperation
Braking is released, motor shaft 1 is limited without rotation so as to rotate.Brake of the present invention is compared to existing friction catch structure
Traditional structure that braking is realized by friction plate is eliminated, is reduced because friction disc wear causes braking moment to reduce, nothing
The problem of legal system is moved, at the same can also fast braking, reduce braking time, improve the service life of brake and safe and reliable
