These Knowledge Of Magnetic Powder Clutch

The hollow shaft magnetic powder clutch transmits torque through the magnetic powder under the electromagnetic effect, has a linear relationship between the excitation current and the transmission torque base, and is an automatic control element with superior multi-purpose performance. The hollow shaft magnetic powder clutch is divided into two types: the inner shell rotating hollow shaft magnetic powder clutch and the outer casing rotating hollow shaft magnetic powder clutch. When the magnetic powder clutch and the clutch are used for continuous sliding of winding and unwinding, the product and the service life are used. There are differences in conditions.

        The hollow shaft magnetic powder clutch is usually used in conjunction with the tension detector. The tension controller automatically controls the torque of the hollow shaft magnetic powder clutch to make the tension constant. Generally, the hollow shaft magnetic powder clutch operates in a slip state, and the tension is controlled by the torque of the hollow shaft magnetic powder clutch in order to keep the tension constant. When the excitation current remains the same, the torque will be transmitted steadily without being affected by the change in speed. This feature is used in tension control, and only needs to adjust the excitation current to accurately control the torque, so as to achieve the purpose of controlling the tension.

  Let us explain to you the installation points of the rotating magnetic powder clutch of the hollow shaft housing:
1. In order to prevent the braking of the cooling stator from causing additional influence (ie load) on the bearing inside the hollow shaft housing rotating the magnetic powder clutch, please additionally set the side holes and clearance of the cage, and do not tighten in the axial direction.

2. The input side and the shaft must be connected using a flexible coupling, and the concentricity, straight angle, etc. of each axis must be controlled within the allowable range of the flexible coupling used. In addition, when bolts are inserted into the shaft end of the hollow shaft magnetic powder clutch, in order to prevent the bearing inside the magnetic powder clutch from being subjected to abnormal load, reserve a certain axial clearance on the elastic coupling.
3. When driving the pulley, in order to avoid additional load on the bearing inside the magnetic powder clutch, it is necessary to control the load within the allowable range.

       Magnetic powder clutch is an important type of electromechanical equipment. We hope that everyone can maintain and maintain equipment in time to make it better put into production.
