Structure and working principle

The brake yoke, the excitation coil springs, disc, armature, spline sleeve, mounting screws, etc., the brake device mounted on the flange (or motors) the rear stretch; sleeve and the spline shaft brake disc coupling.
The brake coil when the rated excitation voltage (DC), the electromagnetic force pull armature, the armature from the brake disc (released), then the drive shaft with the brake disc or start normal operation, when the separation or broken drive power, the brake is off at the same time, then the pressure in the armature spring force to the armature and the brake disc friction torque between the flanges, the drive shaft speed to stop. The brake thermal environment is poor, the drive shaft is long continuous work, if conditions allow, you can brake work, keep the voltage is converted to 70% -80% of the rated voltage to reduce fever.
4 Qian Dai electromagnetic brake chain tail electromagnetic brake
The moving parts of the mechanical stop or slow down the mechanical parts. Commonly known as brakes, brake. Qian Dai primarily by electromagnetic brake brake frame, brake components and control devices and other components. Some of the electromagnetic brake is also equipped with an automatic brake clearance adjustment device member.
Some electromagnetic brake has been standardized and serialized by a professional factory for selection. teflon hose Qian Dai electromagnetic brake is an ideal modern industrial automation actuators, mainly from the transmission system in the mechanical power transmission and control of movement and so on. Compact structure, simple operation, sensitive response, long life, reliable, easy to implement remote control and so on.
It is mainly with the series motor support. Widely used in metallurgy, construction, chemical, food, machine tools, stage, elevators, ships, packaging machinery, and when power (risk prevention) braking and other occasions.
So that the mechanical moving parts to stop or slow down the drag torque must be applied is called the braking torque. Braking torque is the design, selection based on the brake, and its size is determined by the type of machinery and work requirements of the decision. Brake friction material used on the (brake parts) directly affects the performance of the braking process, which will affect the performance of the main factors for the operating temperature and temperature rise speed. Friction material should have a high and stable coefficient of friction and good wear resistance. banjo fitting Metallic and non-metallic friction material sub categories. The former are commonly used cast iron, steel, bronze and powder metallurgy friction material, which has leather, rubber, wood and asbestos.
