Laminated type high-power magneto-rheological fluid clutch

Abstract

The invention discloses a laminated type high-power magneto-rheological fluid clutch. The laminated type high-power magneto-rheological fluid clutch comprises a primary transmission shaft (4), a left rotary magnetic conductance side board (6), a magnet exciting coil (8), a fixing magnetic conductance outer shell (9), a right rotary magnetic conductance side board (14), a secondary transmission shaft (17), a magnetic conductance board (18), a plurality of layer-adjustable inner layer primary friction plate groups (3), outer layer primary friction plate groups (7), outer layer secondary friction plate groups (12) and inner layer secondary friction plate groups (15), inner layer small magnetic isolation ring groups (2), outer layer small magnetic isolation ring groups (5), an inner layer large magnetic isolation ring (13) and an outer layer large magnetic isolation ring (20). Compared with the prior art, the laminated type high-power magneto-rheological fluid clutch adopts a plurality of friction plate groups for transmission, effectively disperses a heat source, reduces the heat dissipation difficulty, utilizes cooling water for cooling, and obviously improves the transmission power and the heat dissipation effect. When the transmitted power is insufficient, a mode of increasing the layers of the friction plate groups can be adopted, and controllable operation of the transmitted power is easy to achieve.

Description

technical field [0001] The invention relates to a magneto-rheological fluid clutch, in particular to a laminated high-power magneto-rheological fluid clutch, which is mainly used in power transmission of high-power machinery and vehicles such as mines and metallurgy. Background technique [0002] Magnetorheological fluid is a new type of intelligent material, which is mainly composed of soft magnetic particles, base carrier fluid and surface additives. Under the action of a magnetic field, it will have a significant rheological effect, that is, when there is no external magnetic field, the performance It is in a free-flowing state and has Newtonian fluid behavior. Under the action of an external magnetic field, the particles in the magnetorheological fluid are arranged in a chain structure along the direction of the magnetic field, and instantly change from a free-flowing state to a semi-solid state, showing Bingham fluid behavior. The shear yield stress can be controlled, a...

Problems solved by technology

The above-mentioned magneto-rheological fluid clutches all have a disadvantage, that is, the power that can be transmitted is low, and the heat dissipation effect achieved is limited, which cannot meet the power transmission requirements of high-power occasions such as mines and metallurgy.
