Planetary magnetorheological transmission device based on shear-extrusion effect

Abstract

The invention provides a planetary magnetorheological transmission device based on a shear-extrusion effect, and belongs to the technical field of mechanical transmission. According to the planetary magnetorheological transmission device based on the shear extrusion effect, a driven outer cylinder is assembled between a left end cover and a right end cover, wherein a gear ring sleeve is assembledon the inner wall of the driven outer cylinder; an input shaft is rotationally connected with the left end cover and the right end cover through bearings; an output shaft is arranged on the outer side of the right end cover; a magnetic conduction sleeve is arranged on the input shaft; a planetary gear is arranged between the magnetic conduction sleeve and the gear ring sleeve; the planetary gearis meshed with outer teeth of the magnetic conduction sleeve and inner teeth of the gear ring sleeve; the two ends of the magnetic conduction sleeve and the two ends of the gear ring sleeve are sealedthrough sealing assemblies to form a closed space; the closed space is filled with magnetorheological fluid; a coil framework is arranged on the input shaft; a magnet exciting coil is arranged on thecoil framework; and the magnet exciting coil is electrically connected with an external power supply. The planetary magnetorheological transmission device has the beneficial effects that large-torquetransmission can be realized, transmission is uniform, the magnetorheological fluid is not influenced by centrifugal force, and real-time adjustment of torque and rotating speed can be realized.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a planetary magneto-rheological transmission device based on the shear-extrusion effect. Background technique [0002] The magnetorheological transmission device is a mechanical transmission device that utilizes the good magneto-rheological effect of magnetorheological fluid to transmit power torque. Magnetorheological fluid is a kind of viscous liquid with high reliability and wide application range. It is a suspension composed of tiny soft magnetic particles with high magnetic permeability and low magnetic hysteresis and non-magnetic liquid. Magneto-rheological fluid exhibits low-viscosity Newtonian fluid characteristics under zero magnetic field conditions, and high-viscosity, low-fluidity Bingham fluid characteristics under strong magnetic field conditions. Macroscopically, magnetorheological fluids have a time unit of milliseconds. The interior rapidly chang...
