Abstract

The invention relates to a high-speed power-off electromagnetic brake. The high-speed power-off electromagnetic brake comprises a shell, a movable component, a static component, an end cover and an output shaft. The movable component comprises a movable friction disc, a plate spring, a connecting disc and a screw. The movable component comprises a static friction plate, magnetic steel, a magnetismconduction ring, a copper coil and a positioning check ring. In order to ensure stable work of the brake under the high rotating speed of 12000rpm, bearings are additionally arranged at the two endsof the output shaft of the brake in the aspect of structural design; and in order to prevent the movable friction plate from damaging the plate spring under high-speed rotation, a connecting disc is used as a guide rod for axial movement of the movable friction plate through clearance fit of concentric rings during design, and the structural design can also effectively avoid the influence of centrifugal force on the radial position of the movable friction plate, so that it is ensured that the brake can work normally under the effect of complex external force.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to a de-energized brake capable of realizing the braking function at a high rotational speed, which is used to match with the motor to realize the power-on electrolytic braking and power-off locking functions of the mechanism. Background technique [0002] Electromagnetic brakes are mainly matched with motors and are widely used in various industrial fields. They have the advantages of simple structure, convenient operation and light weight. The power-off electromagnetic brake can provide a certain braking torque when the power is off, realize the function of locking, and prevent the mechanism from misoperation when the power is off. Domestically produced electromagnetic brakes have problems such as single types, poor reliability, and short service life. [0003] The de-energized electromagnetic brake used in the field of weaponry, on the one hand, is limited in size and ma...
