Power-off electromagnetic brake capable of achieving electric brake release and electric brake recovery

Abstract

The invention relates to a power-off electromagnetic brake capable of achieving electric brake release and electric brake recovery. An armature is arranged on the right side of a magnetic yoke, a compressed spring is disposed between the magnetic yoke and the armature, a pin hole is formed in the upper side of the magnetic yoke, a brake disc is arranged on the right side of the armature, a motor end cap is disposed on the right side of the brake disc, release screws are disposed in the magnetic yoke, one end of each release screw is connected to an L-shaped release plate, the other end of each release screw is connected with the armature, the number of the release screws is two, the two release screws are symmetrically arranged with a main shaft as the center, one side of the L-shaped release plate is provided with a manual release handle, and a traction electromagnet is disposed on one side of the manual release handle and penetrates through the L-shaped release plate to enter the pin hole in the upper side of the magnetic yoke. The power-off electromagnetic brake is simple in structure and high in practicality, and can electrically or manually control a brake release state and a non-brake state.

Description

technical field [0001] The invention relates to the technical field of automatic actuators, in particular to a power-off electromagnetic brake capable of electrically releasing the brake and electrically recovering the brake. Background technique [0002] The electromagnetic power-off brake is a kind of friction brake that is disconnected when the power is turned off, and the spring is used to press the brake disc when the power is off, thereby generating frictional braking. It is mainly used for Y series motors to be matched with YEJ electromagnetic power loss brake motors. This kind of brake has the advantages of compact structure, convenient installation, wide adaptability, low noise, high working frequency, sensitive action and reliable braking. Ideal automation actuator. [0003] At present, if the electromagnetic power-off brake wants to release the braking state when the power is off, it is necessary to grasp the manual release handle and pull it backwards. At this t...

AI Technical Summary

Problems solved by technology

When the handle is put down, the armature will return to the state of pressing the brake disc under the action of the spring force, so that it returns to the state of braking. When the electromagnetic brake on some mechanical equipment is installed at high altitude or far away from the operating table When turning the car or debugging, it is necessary to release the braking state of the motor or the machine, so it is necessary to manually pull the manual release device. However, when you release the release handle, the brake will resume the braking state. If you want to release the brake, you must always pull the manual release device and cannot relax it. This not only poses a safety hazard but is also very inconvenient to the staff in a high-altitude or remote state.
