Problems solved by technology
[0007] (3) Most of the cast aluminum rotor structure is "L" type, with weak load bearing and impact resistance, large volume and heavy weight, requiring a large space for installation;
[0008] (4) The friction plate made by stamping process is mostly used between the electromagnetic brake and the rear end cover of the motor. The flatness of the friction plate is difficult to control, which will directly affect the noise and service life of the brake

A braking force adjustable long-life electromagnetic power-off brake relates to the technical field of electromagnetic brakes, can adapt to different braking torque requirements as the same type of brake, effectively reduces the type selection of the brake, and reduces the cost of arranging a plurality of manufacturing production lines for the brake. According to the long-service-life electromagnetic power-off brake with the adjustable braking force, one end of a compression spring is embedded in a spring hole of a stator shell, the other end of the compression spring makes contact with one side of an armature, and a cast-aluminum rotor is of a T-shaped structure; a threaded hole is drilled in the position, located at the bottom of the compression spring, of the stator shell, the concave-end inner hexagonal flat head screw is embedded into the stator shell in a threaded connection mode, and the flat head position of the concave-end inner hexagonal flat head screw is located at the compression spring. The other two sides of the two friction plates make contact with the armature and one side of the flange plate respectively, a U-shaped groove is formed in the surface of the side, close to the friction plates, of the flange plate, and an outer spigot is formed in the other side of the flange plate.
Description
technical field [0001] The invention relates to the technical field of electromagnetic brakes, in particular to a long-life electromagnetic power-off brake with adjustable braking force, in particular to an electromagnetic brake capable of freely adjusting the braking force. Background technique [0002] At present, the electromagnetic power-off brake is the most common type of brake, and it is also the most widely used brake. Its application fields include nuclear power, wind power, automobiles, smelting, elevators, lifting and transmission, etc.; therefore, electromagnetic brakes The market is vast and various. [0003] However, since the electromagnetic power-off brake is provided by the compression spring to provide positive pressure for the armature, the friction between the armature and the friction plate produces a braking effect, so the spring force is an extremely important parameter. However, the adjustment of the spring force of the existing electromagnetic power...
