Problems solved by technology
[0004] When the electromagnetic brake is working, the electromagnetic coil and the friction plate will generate a lot of heat. If the heat is not dissipated in time, the efficiency and life of the brake will be affected. The increase in temperature will increase the energy consumption of the electromagnetic coil
[0005] "A motor brake" disclosed in CN201174638Y, the motor brake is provided with a fan wheel cooling device, although the fan wheel can play a certain role in cooling, but the cooling effect is not ideal
If the ambient temperature is higher than the temperature of the brake, the fan becomes the heater of the brake instead; in addition, the general electromagnetic brake uses a single-voltage power supply, and the electromagnet coil is energized for a long time, regardless of the holding and pulling voltages. Quite bad for energy saving

The invention relates to a high-temperature resistant and energy-saving electromagnetic brake, which comprises a magnetic yoke body (1), an electromagnetic coil (2), an armature (3), an armature reset spring (8), a static friction disc (4) and a dynamic friction disc (5). An internal water chamber (100), an external water chamber (101) and a communicating pipe (104) are arranged inside the magnetic yoke body (1), and a water inlet pipe (102) and a water outlet pipe (103) are arranged on the magnetic yoke body (1). The water inlet pipe (102) and the water outlet pipe (103) are respectively communicated with the internal water chamber (100) and the external water chamber (101) which are communicated by the connecting pipe (104). The electromagnetic brake adopts a circulating water cooling mode to dissipate heat for friction discs and the electromagnetic coil, which has good heat dissipation effect and reduces the energy consumption of the electromagnetic coil. In addition, the water flow direction of the circulating water, which first enters the internal water chamber of the magnetic yoke body and then flows to the external water chamber, can not only increase the heat dissipation effect, but also effectively prevent the damage to the electromagnetic coil caused by heat radiation at high temperature.
Description
technical field [0001] The present invention relates to brakes, in particular electromagnetic brakes. Background technique [0002] The existing electromagnetic brake mainly includes a yoke body, an electromagnetic coil, an armature, an armature return spring, and two friction plates; Connected to the mechanical rotating shaft, the two friction plates are respectively fixed on the armature and the yoke body, and the two friction plates face each other. [0003] The working principle of the electromagnetic brake is: during mechanical braking, the electromagnetic coil is energized, and the armature is subjected to the electromagnetic attraction force to overcome the action of the armature return spring and move axially on the mechanical shaft, leaning against the yoke body, and the two friction plates contact and rub. Friction brakes the mechanical shaft. [0004] When the electromagnetic brake is working, the electromagnetic coil and the friction plate will generate a lot o...
