The setting of the structure so that after iron core power loss, spring can quickly by armature be pushed to friction plate on armature with
Brake disc fits, so that the structure of entire brake is more stable, and further improves the braking effect of brake.
In above-mentioned electromagnetic power-off brake, the brake disc is equipped with elastic piece, and the elastic piece turns down to form gear
Piece, spline is offered in the brake disc, and the baffle can be embedded in spline and fit with the side wall of spline.
The setting of the structure, so that brake disc can stop operating under the action of armature, baffle energy in motor operation
Rotor is buffered to the impact force of brake disc ontology, the easy for installation and stability of elastic piece is preferable, after prolonged use, still
Preferable buffer function can be played.
Compared with prior art, this electromagnetic power-off brake has the advantage that
1, it is connected on armature and fixed plate using by friction plate, and two friction plates are located at the both ends of brake disc,
It can be attracted with iron core to which armature only needs to meet, friction plate can be used the biggish material of frictional force and be made, therefore armature
It is more with the selection of friction plate, more sufficiently.
2, the setting of recess, so that armature is when towards iron core or far from iron core movement, guide post is generated with armature
Friction is small, while also facilitating the installation of guide post, further improves the braking effect of brake.
