Problems solved by technology

However, when the electromagnetic force attracts the armature 15, it needs to overcome the force of the spring 16. When the electromagnetic force generated by the stator 11 is not strong enough, the excessive force of the spring 16 will cause the overall response time of the brake to be long
At the same time, the friction plate 12 may be deflected during operation due to size problems. During the deflection process, it will inevitably rub against the armature 15 and the baffle plate 13. In addition to noise, abnormal wear will also occur. When the friction plate 12 wears to To a certain extent, the braking performance of the brake is invalid

Abstract

The invention provides a friction plate assembly, a braking device and a motor. The friction plate assembly comprises a first elastic piece, a first friction plate and a second friction plate, whereinthe first friction plate is coaxial with the second friction plate; the first elastic piece is between the first friction plate and the second friction plate, and the restoring force of the first elastic piece makes the first friction plate and the second friction plate away from each other. The friction plate assembly has a high degree of freedom, and the operation balance can be improved. The braking device with the friction plate assembly can q make a quick response, the operation balance is improved, and abnormal wear is avoided.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to a friction plate assembly, a brake and a motor. Background technique [0002] The brake is an important basic component, which integrates mechanical, electrical and electronic technologies, and is mainly used for precise control and braking of rotating mechanisms such as motors. The brake is installed in the servo motor. When the servo motor is working, if the response time of the brake is long, and the response time of the brake is longer than the response time of the motor, then the motor starts and the brake does not start, which will cause abnormal wear of the brake, brake failure, and potential safety hazards. . At the same time, since the friction plate is a non-rigid material, during the braking process, the friction plate will rotate several times, and the friction will work until the braking is completed. During this process, the friction plate will deflect the angle, ca...
