Two-way-controlled liquid viscosity speed regulation clutch

Abstract

The invention discloses a two-way-controlled liquid viscosity speed regulation clutch comprising a transmission mechanism, a control mechanism and a box body. Control oil ways are arranged in a driving shaft and a driven shaft and do not communicate with an axial lubricating oil pipe of the driving shaft; a first radial oil way in a driving shaft transparent cover communicates with the first axial oil way of the driving shaft; a second radial oil way in the driving shaft transparent cover communicates with the second axial oil way of the driving shaft and a third radial oil way in a first piston cylinder; and a first radial oil way in a driven shaft transparent cover communicates with the first axial oil way of the driven shaft and a second radial oil way in a third piston body cylinder. According to the two-way-controlled liquid viscosity speed regulation clutch, the control oil ways are arranged in the driving shaft and the driven shaft, pipelining is omitted, the structure is compact, the part volume is reduced, and the integration degree is high. Besides, a ball head plunger reset mechanism is adopted, abrasion is reduced, and the service life of a workpiece is prolonged.

Description

technical field [0001] The invention relates to a speed regulating clutch, in particular to a two-way controlled liquid viscous speed regulating clutch. Background technique [0002] The hydraulic viscous speed regulating clutch is a kind of energy-saving device for hydraulic transmission. Its definition is that the speed of the active part is constant, and the speed of the driven part can realize stepless speed regulation by controlling the thickness of the oil film. It has good speed regulation performance and can be widely used It is used for speed regulation of high-power pumps, fans and various working machines in petroleum, chemical industry, metallurgy, electric power, coal and other industries, which can effectively solve the problems of throttling loss and energy waste caused by water pumps, fans and other working machines. , the energy-saving effect is remarkable; at the same time, it can avoid the impact on the power grid caused by the frequent starting of the mot...

AI Technical Summary

Problems solved by technology

The various technical solutions proposed by these Chinese patents have their own advantages, and have also solved some difficult problems in practical applications. However, their lubricating oil circuit, control oil circuit, control mechanism, and transmission mechanism are similar, and they all adopt one-way control. The piston body is pressed tightly, the active and passive friction plates are unevenly stressed, the friction pair is eccentrically worn, and the power transmission is not stable, which affects the stability of the hydraulic viscous speed control device.
