The invention relates to the technical field of clutch parts, and discloses a magnetic powder clutch for an automatic control system. The magnetic powder clutch comprises a shell, a coil device is arranged in the middle of the inner wall of the shell in a sleeving manner, a driving disc is movably arranged on one side of the inner ring of the coil device in a sleeving manner, and a driven disc is movably arranged on the other side of the inner ring of the coil device in a sleeving manner. The space between the driving disc and the driven disc is filled with magnetic powder, the surface, corresponding to the side face of the driving disc, of the coil device is fixedly sleeved with a main sealing air ring, and the surface, corresponding to the side face of the driven disc, of the coil device is fixedly sleeved with an auxiliary sealing air ring. According to the magnetic powder clutch for the automatic control system, a middle moving rod is promoted to drive a rubber ring to move and deform back and forth through rotary extrusion of the driving disc, so that the magnetic powder above the rubber ring is gathered towards the middle of the shell, the problem of non-uniform distribution of the magnetic powder due to the factors such as centrifugal force generated by idling of the driving disc is solved, the effect of hardening and transmitting torque of the magnetic powder during electrification is ensured, and normal operation of transmission work of the magnetic powder clutch is maintained.
Description
technical field [0001] The invention relates to the technical field of clutch components, in particular to a magnetic powder clutch for an automatic control system. Background technique [0002] The magnetic powder clutch is a clutch device based on the electromagnetic principle and using magnetic powder to transmit torque. It is composed of an active component and a driven component. The space between the two components is filled with granular magnetic powder, and the coil is electromagnetically energized. , Attracting magnetic powder to produce hardening phenomenon makes the active component drive the driven component to rotate. It has the advantages of fast response, simple structure, no pollution, no noise, no shock and vibration, etc. It is widely used in printing, packaging, papermaking and textiles and other fields. [0003] However, there are still some defects in the use of the magnetic powder clutch: First, when the magnetic powder clutch is not energized and the a...
