The electromagnet is a key component of the electromagnetic brake, which has a great influence on the performance stability and reliability of the electromagnetic brake. When the brake is used continuously on a long slope or when the emergency brake is used at high speed, the temperature of the working parts of the brake will rise sharply. When the temperature is high to a certain level, the friction coefficient of the brake friction pair will decrease due to the influence of mechanical, physical and chemical factors,
Introduction of electromagnetic brake
The electromagnet is a key component of the electromagnetic brake, which has a great influence on the performance stability and reliability of the electromagnetic brake. When the brake is used continuously on a long slope or when emergency braking is used at high speed, the temperature of the working parts of the brake will rise sharply. When the temperature is high to a certain level, due to the influence of mechanical, physical and chemical factors, the friction coefficient of the brake friction pair decreases and the braking efficiency of the brake decreases. This phenomenon is called the thermal decay of braking efficiency, the anti-thermal decay of the brake is one of the important indicators to evaluate the performance of the brake, and then, the temperature field of the electromagnet and friction ring in different periods of the long slope is analyzed by finite element analysis method, and the accuracy of the analysis model and method is verified by experiment.
The electromagnetic brake is the actuator of the entire braking system, and the electromagnetic brake is installed on the trailer wheel. The whole device is mainly composed of electromagnet, lever transmission mechanism, front and rear brake shoes, bottom plate and friction ring.
A mechanical part that stops or slows down the moving parts in a machine, commonly known as brakes and brakes. The brakes are mainly composed of brake frames, brake parts and operating devices. Some brakes are also equipped with an automatic brake clearance adjustment device. In order to reduce the braking torque and structural size, the brake is usually installed on the high-speed shaft of the equipment, but large equipment with high safety requirements (such as mine hoists, elevators, etc.) should be installed on the low-speed shaft close to the working part of the equipment.
Some brakes have been standardized, serialized, manufactured by professional factories to choose from.
Operating principle of electromagnetic brake
The friction ring rotates with the brake drum, and the electromagnet and the drive rod are connected together by a circlip. When braking starts, the controller sends out a braking signal, and the electromagnet is energized to generate electromagnetic attraction, which is adsorbed on the friction ring. Since the electromagnet is constrained by the drive rod and slides relative to the friction ring, the friction force acting on the electromagnet drives the drive rod connected to the electromagnet to rotate around the fulcrum, and the driven end of the lever opens the two friction shoes of the brake and presses them to The brake drum generates braking torque. When the brake is over, the electromagnet is de-energized, and the suction force and friction force disappear. Under the action of the pulling force of the return spring, the friction shoe leaves the brake drum to release the brake.
Electromagnetic brake is an ideal automation actuator in modern industry, which mainly plays the role of transmitting power and controlling motion in mechanical transmission system. It has the advantages of compact structure, simple operation, sensitive response, long service life, reliable use, and easy remote control.
