Radial multi-layer magneto-rheological clutch

Abstract

The invention discloses a radial multilayer type magneto-rheological clutch which mainly comprises an output shaft, a left disk, a housing, a supporting disk, rotors, coils, a right disk and an input shaft. A cavity is formed by the surrounding of the left disk, the right disk and the housing arranged between the left disk and the right disk; the output shaft is fixedly connected to the outer surface of the left disk; the part, which extends into the cavity, of the input shaft is connected with the supporting disk by a flat key; rotors I, rotors III, rotors II and rotors IV are fixedly arranged at intervals on the left and right end faces of the supporting disk along the radial direction, wherein the rotors II and the rotors IV are arranged on the inner surfaces of the left disk and the right disk in a manner of being interleaved and matched with the rotors I and the rotors III; equal even numbers of rotors are respectively and uniformly arranged along the respective peripheral direction; the rotors are also respectively wound with the coils; gaps are formed between the rotors on different circumferences; magneto-rheological fluid is filled in the gaps. The radial multilayer type magneto-rheological clutch utilizes the radial working gaps and radial multilayer stacking, has a large transmitting torque and has a compact structure; the coils on the rotors also can be flexibly disassembled and replaced.

Description

technical field [0001] The invention relates to a magneto-rheological clutch, in particular to a radial multi-layer magneto-rheological clutch which utilizes a radial working gap, radially multi-layer superimposes, can provide large torque output, and can flexibly replace coils. Background technique [0002] The so-called clutch is a device that uses "off" and "on" to transmit mechanical motion and power. For a long time, the friction clutch has been the most widely used and the oldest type of clutch, but it is prone to heat, wear and noise. In order to improve the reliability of the clutch transmission and reduce the weight of the clutch transmission device, a magnetic powder clutch appeared later. This type of clutch is made by adding magnetic powder between the driving part and the driven part of the transmission device, and the magnetic powder is in a loose state when no power is applied. The active part and the driven part are in the "off" state, and the magnetic powde...
