Mechanical parts that cause the movement of the machine to stop or slow down. Commonly known as brake, brake. Brake mainly by the brake, brake and control device, etc.. Some of the brake is also equipped with brake clearance of the automatic adjustment device. In order to reduce the braking torque and the structure size, the brake is usually mounted on the high speed shaft of the device, but the safety requirements of large equipment (such as the mine hoist, elevator, etc.) should be installed in the low speed axis close to the working part of the device.
Some brakes have been standardized and series, and are manufactured for use by a professional factory.
Electromagnetic brake is a kind of ideal automatic execution element in modern industry, and it plays a key role in mechanical transmission system. Has the advantages of compact structure, simple operation, flexible response, long service life, reliable use, easy to realize long-distance control, etc..
It is mainly related to the series motor. Widely used in metallurgy, construction, chemical, food, machine tools, stage, elevator, shipping, packaging, etc. machinery and in the event of a power outage (emergency) brake and other occasions.
The resistance torque required to stop or slow down the mechanical operation of the machine is called a braking torque. Braking torque is the basis of design and selection of brake, the size of the machine is determined by the type and working requirements. The performance of the friction material (brake) used in the brake directly affects the braking process, and the main factors affecting the performance of the brake are working temperature and temperature rising speed. Friction material should have high and stable friction coefficient and good wear resistance. Friction materials for two types of metals and non metals. The former commonly used cast iron, steel, bronze and powder metallurgy friction materials, etc., the latter has leather, rubber, wood and asbestos, etc..
