Conical extrusion-shearing type magnetorheological clutch

Abstract

The invention discloses a conical extrusion-shearing type magnetorheological clutch. An iron core input disc is fixed at a front end of an input shaft and an armature output disc sliding axially is arranged at a front end of an output shaft, or the armature output disc sliding axially is arranged at the front end of the input shaft and the iron core output disc is fixed at the front end of the output shaft; a containing cavity is formed between the iron core input disc and the armature output disc; magnetorheological fluid is filled in the containing cavity; a sealing ring for sealing the magnetorheological fluid in the containing cavity is arranged on the periphery of the containing cavity; a coil for driving the armature output disc to move axially to the iron core input disc is further arranged in a working cavity; and an adjusting device for adjusting the volume of the containing cavity is further arranged between the iron core input disc and the armature output disc. The conical extrusion-shearing type magnetorheological clutch has the advantages that: when the clutch is in the working state, through attraction to the armature output disc by a magnetic field generated by the coil, the volume of the containing cavity is reduced, and meanwhile, an extrusion and shearing force is generated against the magnetorheological fluid, so as to transfer a greater torque; in addition, the conical extrusion-shearing type magnetorheological clutch is small in volume, reliable in performance, compact in structure, and good in effect.

Description

technical field [0001] The invention relates to a conical squeeze-shear type magneto-rheological clutch. Background technique [0002] Magnetorheological fluids are widely used in aerospace / mechanical processing / precision engineering / construction / Medical and other fields. [0003] The magneto-rheological clutch realizes the functions of coupling and separation of the clutch through the control of the strength of the external magnetic field, and can even realize the stepless change control of the torque transmission. It overcomes the shortcomings of traditional clutches such as easy wear and high noise, with its simple structure, no mechanical wear, low noise, quick response (within 10 milliseconds), low energy consumption, stepless speed regulation and better integration with computer technology Combining the advantages of realizing intelligent control has aroused extensive research by domestic and foreign scholars and industrial circles, and has made remarkable progress ...
