Problems solved by technology

Such as foreign magneto-rheological patents: a double-disc magneto-rheological clutch disclosed in U.S.Pantent 5896965, a multi-disc magneto-rheological clutch disclosed in U.S.Pantent 5823309; A radial self-pressurized magnetorheological fluid clutch, a centrifugal magnetorheological fluid clutch disclosed in CN01137376.6, but these patents have less consideration for the heat dissipation of the clutch, and the heat dissipation characteristics are not good, so they cannot be applied to long-term sliding. Poor working conditions, low slip power

Embodiment Construction

[0012] The present invention and an embodiment are further described below in conjunction with accompanying drawing:

[0013] As shown in the accompanying drawings, the double-disc magneto-rheological clutch of the present invention is mainly composed of a fixed part and a rotating part. Shell 8, 13, excitation coil 11, rotating sealing ring 14, magnetic isolation ring 12 and oil inlet and outlet 9, 1; the rotating part includes driving shaft 3, rotating blade 7, driving disc 10, driven disc 15, driven The shaft 18 and the magnetorheological fluid sealed between the master and slave discs. The main and driven shafts 3 and 18 are respectively arranged on the left and right magnetic conduction shells 8 and 13 on the main and driven shafts 3 and 18, and the left and right magnetic conduction shells 8 and 13 are buckled and fixed together. The shafts 3 and 18 are connected to the magnetic isolation bearing blocks 6 and 16 through the bearing 5, the lock nut 4 compresses the beari...

Abstract

The invention relates to a double-disk type magnetorheological clutch which comprises a driving disk, a driven disk, a magnetorheological fluid, a transmission shaft, a rotating blade, a magnetic conduction shell, a magnet exciting coil, an insulation ring, a fluid inlet, a fluid outlet, a bearing and a sealing element, wherein the driving disk is connected to a driving shaft; the driven disk is connected to a driven shaft; the magnetorheological fluid is filled between primary and secondary magnetic conduction disks through the fluid inlet; a sealing ring device is rotated so as to keep the magnetorheological fluid between the two disks; the magnet exciting coil is fixed in the magnetic conduction shell with no need of an electric brush; and the magnetorheological fluid is sealed between the two disks, and the rotating blade is arranged on the transmission shaft. The rotating blade is rotated under the driving of the transmission shaft, so air is guided to circularly flow through an air vent, and the excellent radiating property is maintained. The double-disk type magnetorheological clutch has the advantages of compact structure and good radiation property, and can be used for natural air cooling.

Description

technical field [0001] The invention relates to a magnetorheological clutch, in particular to a double-disk magnetorheological fluid clutch suitable for transmission machinery. Background technique [0002] The traditional fluid viscous transmission technology is a new form of fluid transmission developed from abroad in the mid-1970s. It is based on Newton's law of internal friction, using the shearing action of the oil film to transmit torque, and controlling the transmission torque by changing the thickness of the oil film. size. It is characterized by high speed regulation sensitivity and good stability, and the output speed can be adjusted steplessly within the range of 0-100%. However, it requires a huge oil supply system and complex control devices, which is bulky and expensive. [0003] Magnetorheological fluid is a smart material that can produce significant rheological properties under the action of a magnetic field. In the past ten years, due to its superior rhe...
