Description

Magnetic powder brake with temperature protection mechanism
Technical Field
The invention relates to the technical field of magnetic powder brakes, in particular to a magnetic powder brake with a temperature protection mechanism.
Background
Magnetic powder brake, english name: magnetic particle brakes (commonly known as magnetic particle brakes, naturally cooled) are based on electromagnetic principles and utilize magnetic particles to transmit torque. It has the characteristic of basically linear relation between exciting current and transmission torque. The device can transmit certain torque under the condition of not relating to the slip, and has the advantages of high response speed, simple structure, no pollution, no noise, no impact vibration, energy conservation and the like. The magnetic powder brake is an automatic control element with multiple purposes and excellent performance. The tension control device is widely applied to unwinding and winding tension control in paper making, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy, tablet presses and other related winding processing industries. Magnetic particle brakes are also often used for dynamometer loading and braking of transmission machinery, among other things.
The magnetic powder brake is formed by combining a transmission unit (input shaft) and a driven unit (output shaft). In the space between the two sets of cells, granular magnetic powder (volume of about 40 μm) is filled. When the magnetic coil is not electrically conducted, torque is not transmitted from the transmission shaft to the driven shaft, but when the coil is electromagnetically electrified, magnetic powder is attracted by the action of magnetic force to generate a hardening phenomenon, and the torque is transmitted between continuous sliding. Magnetic particle brakes are a superior automatic control element. The magnetic powder is used as a working medium, and the exciting current is used as a control means, so that the aim of controlling braking or torque transmission is fulfilled. The output torque and the exciting powder current have good linear relation and are irrelevant to the rotating speed or slip, and the device has the advantages of high response speed and simple structure.
Due to the characteristics of the magnetic powder brake, the magnetic powder brake is widely applied to unwinding and winding tension control in paper making, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy and other related winding processing industries. In addition, the magnetic powder clutch can also be used for buffer starting, overload protection, speed regulation and the like. Magnetic particle brakes are also often used for dynamometer loading and braking of transmission machinery, among other things. The existing magnetic powder brake often has the following defects:
1. the existing magnetic powder brake often causes element damage or aging due to overheating in the operation process, thereby affecting the operation of the magnetic powder brake equipment or reducing the stability of the magnetic powder brake equipment, further affecting the use of the equipment and reducing the service life of the device.
