The invention proposes a planetary magneto-rheological transmission device based on a shear-extrusion effect, which belongs to the technical field of mechanical transmission. This is a planetary magneto-rheological transmission device based on the shear-extrusion effect. The driven outer cylinder is installed between the left end cover and the right end cover. The inner wall of the driven outer cylinder is equipped with a gear ring sleeve. The input shaft is connected to the left end cover and the right end through bearing rotation. Cover, the output shaft is set on the outside of the right end cover, the magnetic sleeve is set on the input shaft, the planetary gear is set between the magnetic sleeve and the gear ring sleeve, the outer teeth of the planetary gear and the magnetic sleeve, and the inner teeth of the gear ring sleeve Mesh, the two ends of the magnetic sleeve and the gear ring sleeve are sealed by the sealing assembly to form a closed space, the closed space is filled with magnetorheological fluid, the input shaft is equipped with a coil skeleton, the coil skeleton is provided with an excitation coil, and the excitation coil is electrically connected to the external power supply. The beneficial effect of the invention is that large torque transmission can be realized, the transmission is uniform, the magnetorheological fluid is not affected by centrifugal force, and the real-time adjustment of torque and rotation 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...
