Dry multi-piece friction electromagnetic disc type power-off brake

Abstract

The invention discloses a dry multi-piece friction electromagnetic disc type power-off brake. The power-off brake comprises a brake body, wherein a mounting seat is arranged at the bottom of the brakebody, a damping device is fixedly mounted on the lower surface of the mounting seat, and a shell is fixedly mounted on the upper surface of the mounting seat; a bearing is fixedly mounted on the front surface of the shell, a force applying shaft is rotatably mounted in the bearing, and a force applying bearing is fixedly mounted outside the bearing; and the front surface, close to the outer sideof the force applying bearing, of the shell is provided with external threads. By arranging the damping device, the influence caused by vibration to the brake body is reduced, the situation that internal parts in the brake body are damaged due to vibration is avoided, a good braking effect is guaranteed, the normal use of the brake body is guaranteed, accident is avoided, and unnecessary injury isreduced; and by arranging a dustproof device, a dustproof effect is achieved, so that the situation that impurities such as dust enter the brake body is avoided, and the burden of the internal partsis alleviated.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to a dry multi-disc friction-electromagnetic disk-type power-loss brake. Background technique [0002] A brake is a device that has the functions of slowing down, stopping or maintaining a stopped state of moving parts or moving machinery. It is a mechanical part that stops or slows down moving parts in machinery, commonly known as brakes or brakes. [0003] At present, the commonly used brakes do not have a shock absorption function. During use, the internal parts of the brake are loosened due to vibration, resulting in poor braking effect and affecting normal use, which may lead to serious accidents and unnecessary damage; the dustproof effect of the brake is poor. It is easy to cause dust and other impurities to enter the interior of the brake, which increases the burden on internal parts, shortens the service life, and affects normal use; the heat dissipation effect of the brake ...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used brakes do not have a shock absorption function. During use, the internal parts of the brake are loosened due to vibration, resulting in poor braking effect and affecting normal use, which may lead to serious accidents and unnecessary damage; the dustproof effect of the brake is poor. It is easy to cause dust and other impurities to enter the interior of the brake, which increases the burden on internal parts, shortens the service life, and affects normal use; the heat dissipation effect of the brake is poor. When braking, a large amount of heat is generated due to friction, and the heat is not dissipated in time. It is easy to cause damage to the brake and cause accidents issued, there are certain security risks
