Multi-piece magnetorheological fluid electromagnetic clutch

Abstract

The invention discloses a multi-piece magnetorheological fluid electromagnetic clutch which is in a multi-piece structure. A plurality of gaps between drive and driven friction plates are filled with magnetorheological fluid serving as medium, a plurality of magnetorheological fluid operating ring surfaces are formed, magnetic field intensity of the gaps is high, distribution of the gaps is reasonable, high torque can be transmitted, high transmission power can be controlled with low excitation current, automatic control is easy to implement, and engaging and disengaging can be stabilized. Input and output shafts, both provided with end bearings, and a housing form a whole installed inside a frame. The multi-piece magnetorheological fluid electromagnetic clutch is compact in structure, high in rigidity, convenient to mount and maintain, simple in structure, high in reliability, stable in transmission, and applicable to various small- and medium-sized automatic devices and servo drivers.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic clutches, in particular to a multi-plate magnetorheological fluid electromagnetic clutch. Background technique [0002] A clutch is a device that uses "off" and "on" to transmit mechanical motion and power. Due to the rapid development of modern science and technology and industry, higher and higher requirements are put forward for clutch transmission, mainly high load capacity, high efficiency, high reliability, small size, light weight, quick separation and engagement, smooth and no impact , It is required to realize long-distance automatic operation and control in various automation equipment. [0003] For a long time, friction clutches have been the most widely used and have the longest history of a type of clutch, but they are prone to heat and wear. In order to improve the quality and reliability of the clutch transmission and reduce the weight of the clutch transmission, people ha...
