Troubleshooting and maintenance of hysteresis clutch

Troubleshooting and maintenance of hysteresis clutch

 

 

 

 

But in the production, there will also be failures. So, what are the main failures of the hysteresis brake?

 

 

 

1. The square coupling between the motor shaft and the impeller shaft falls off after loosening, the motor shaft idles and the hydraulic cylinder does not act.

 

 

 

2. The hydraulic push rod of the brake release is bent and deformed, and the brake release is not in place.

 

 

 

3. The hydraulic pushrod brake spring is broken and the brake cannot be closed.

 

 

 

4. The movable hinge point of the brake frame is stuck, and the opening and closing action of the brake is slow or not.

 

 

 

5. The movable hinge pin of the brake frame is loose, and the brake does not work in place;

 

 

 

6. The brake belt and brake wheel are seriously worn, and the brake torque is reduced or lost.

 

 

 

7. The driving motor of the hydraulic push rod brake breaker is out of phase, and the motor and the brake breaker do not act.

 

 

 

 

How to deal with the stuck hysteresis brake and the causes are as follows:

 

 

 

1、 Cause of the sticking of the hysteresis brake

 

 

 

1. Due to the long time of transportation or placement, the hysteresis between the two groups of units of the hysteresis brake is scattered to one side. If the excitation is not done before the start-up, the hysteresis brake will be stuck.

 

 

 

2. The manufacturing accuracy of the hysteresis brake is low, and the concentricity of the rotor is not enough, resulting in uneven or stuck output torque.

 

 

 

3. In the production process of hysteresis brake, excessive hysteresis is sealed.

 

 

 

4. The use of inferior magnetic particles can cause seizure.

 

 

 

2、 In view of the above situation, the following solutions are suggested

 

 

 

1. When choosing to buy the hysteresis brake, choose the product with guaranteed quality.

 

 

 

2. Under the condition of no excitation, the drive side rotates as fast as possible (below 1800rpm) for about 1 minute, and then the excitation current is set at the rated 1 / 4-1 / 5. On the one hand, the drive side rotates, on the other hand, it opens in 5 seconds, closes in 10 seconds, and exhausts excitation for about 20 times.

 

 

 

3. Before formal operation or after the device moves, it must be operated evenly before formal operation. In this way, it can produce smooth torque and even operation.

 

 

 

 

 

Application scope

 

 

 

Ys hysteresis products, with its high precision, high speed and stable performance, have become the manufacturers pursuing high-precision equipment in the torque control industry. At the same time, it has greatly improved product quality and machine production efficiency, and accelerated the industrial upgrading of the equipment industry. Ys hysteresis technology is widely used in the control of tension and torque in the winding process, such as wire and cable, optical fiber cable, paper, textile, printing, paper making, packaging, metal foil, fiber, rubber, film, film, etc. The load can be simulated on a test bench or a dynamometer with tiratron. (application models such as: in the application of winding equipment such as straight twister, wrapping machine, stringer, strander, enameled wire equipment, pulling machine, rewinding machine, optical fiber coating machine, optical fiber cable wrapping machine, winding machine, etc.)

 

 

 

characteristic

 

 

 

1. Non contact torque transmission: the air gap of the brake or clutch of the mechanical component, which changes continuously and then becomes constant to avoid any wear

 

 

 

2. Continuously adjustable torque: brake torque or transferable torque is only dependent on current, largely independent of speed, and is continuously effective from zero to speed.

 

 

 

3. High power continuous mode, overload: the power brake series can sustain high power continuously. It can withstand overload in a short time

 

 

 

4. High speed, up to 12000rpm

 

 

 

5. Systems for brakes and clutches and generally available control components are standardized for most applications.
