Abstract

The embodiment of the invention discloses an oil film clutch. The oil film clutch comprises a transmission system, a control system and a speed regulating system, wherein the transmission system comprises a driving shaft, a supporting plate, a driving friction sheet, a driven friction sheet, a driven drum, a driven plate and a driven shaft; the control system, comprising a piston, an elastic element and a positioning plate, is positioned in the transmission system; the speed regulating system is arranged on the driven shaft and is positioned in a spring displacing chamber; and the speed regulating system comprises an oil tank, a first directional valve, a second directional valve, a first oil channel hose, a second oil channel hose, a third oil channel hose, a signal amplifier, a pressuresensor and a control circuit. According to the oil film clutch in the embodiment, oil can be automatically drained and supplemented for the speed regulating system, so that the problem of speed fluctuation of the oil film clutch under controlled oil pressure less than 0.5MPa can be reduced; and the stability and the accuracy of the output rotating speed of the oil film clutch can be improved.

Description

technical field [0001] The invention relates to the technical field of clutches, in particular to an oil film clutch, and also to a fluid-viscosity speed regulating device that can be applied to a low-voltage system and can suppress speed fluctuations. Background technique [0002] The oil film clutch belongs to the transmission device, and the technology it uses is the hydro-viscous drive (HVD) technology based on Newton's law of internal friction, which uses the shearing effect of the oil film between the main and passive friction plates to transmit power. It can work under slipping conditions for a long time, and can realize synchronous transmission between the main and driven shafts. The oil film clutch has excellent speed regulation performance and can realize stepless speed regulation. The oil film clutch is widely used in the speed regulation of some high-power water pumps, fans and other working machines, which can effectively solve the energy waste problem caused b...
