Abstract

The invention relates to a multiple-piece magneto-rheological fluid torque transferring device. The device has a multiple-piece layered structure, so that transferred torque is increased exponentially; the torque transferred by the device can be adjustable within a wide range by changing the current of a magnet exciting coil in the device; and under the condition that a driven shaft is fixed, the device can output adjustable and flexible torque which can be used as protecting links in a damper, a torsion applying device or a transmitting system. The device consists of a fixed supporting part, a driving rotor part, a driven rotor part, the magnet exciting coil, magneto-rheological fluid, a seal part and the like. The fixed supporting part consists of a left bearing end cap, a right bearing end cap, a shell left end cap, a shell right end cap, a left magnet yoke and a right magnet yoke. The driving rotor part and the driven rotor part consist of a driving shaft, driving discs, non-magnetic aluminum sleeves, a driven shaft and driven discs. The seal part comprises a dynamic seal ring, a seal ring baffle plate and a rubber oil seal. The multiple-piece magneto-rheological fluid torque transferring device has the characteristics of low energy consumption, wide torque adjustable range, sensitive response, excellent performance and the like.

Description

technical field [0001] The invention relates to a torque transmission (output) device, in particular to a torque transmission (output) device which is adjustable and has a large transmission (output) range. Background technique [0002] Magneto-rheological fluid materials (Magneto-rheological Fluid Materials) are considered to be a new generation of smart materials with great development potential in the field of material engineering, precisely because of their great development potential, uniqueness of magneto-rheological effects, and stable rheological properties. Its characteristics have attracted the attention of many developed countries. In view of its unique properties, magnetorheological fluid and its application devices have broad application space and market prospects in automation equipment industry, aerospace, automobile, fitness equipment and other fields. [0003] In the late 1940s, the rheological properties of magnetorheological fluids were first discovered b...
