Characteristics And Fault Analysis Of Magnetic Powder Clutch With Double Outshaft
Release Date:31/08/2019
The double-outlet magnetic powder clutch is based on the electromagnetic principle and uses magnetic powder to transmit torque, and has a linear relationship between the exciting current and the transmitting torque.It can transfer certain torque when it has nothing to do with slip, and has the advantages of quick response, simple structure, no pollution, no noise, no impact vibration and energy saving, etc. It is a kind of multi-purpose and superior automatic control element.The drive body (input end) and the driven body (output end) of the dual-shaft magnetic powder clutch are on the concentric shaft, and there is a magnetic gap between them and supported by the shaft, which can rotate freely. A magnetic powder (ferromagnetic powder) with high conductivity is filled in the middle of the magnetic gap and an excitation coil is arranged around the base to ensure the passage of magnetic flux. When the drive body is rotated without excitation, the magnetic powder is attached to the working face of the drive body due to centrifugal force.
The most common abnormal phenomena of dual-shaft magnetic powder clutch are insufficient torque, continuous skid, high temperature or short service life. The main reasons are as follows:
1. The reason for the insufficient torque may be that the magnetic powder clutch selection does not meet the needs of the machine and the force is not enough to satisfy the load level, etc.
2, The cause of continuous skid may be caused by excessive load or continuous sliding working time is too long.
3. The reason of high temperature is directly related to the working time of the dual-out-of-shaft magnetic powder clutch, as well as the load and operating environment.
4, Short service life with the daily operation, daily maintenance has a great relationship, in addition, and the quality of magnetic powder is also a direct relationship, and so on.
