On pages 106-108 of the book "Study on Fluid Shearing Transmission Mechanism of Fluid-Viscous Speed-governing Clutch" by Huang Jiahai of Zhejiang University in April 2011, he disclosed a manually adjustable liquid-viscous speed-governing clutch, which relies on the lock on the input shaft. Tighten nuts and fixing screws to manually adjust the distance between the active and passive plates, but every time you adjust the distance between the active and passive plates, you must disassemble the box, and then install the box after the adjustment, which is inconvenient and time-consuming. and other shortcomings
CN103790998A discloses a double-plate fluid-viscous speed-regulating clutch. The two oil circuits of the input control oil and the input working oil in the device are relatively complicated, the processing of the relevant parts is difficult, and the test function of accurately adjusting the size of the oil film gap cannot be performed. , CN103790997A discloses a manual adjustment type fluid-viscous adjustment clutch, the distance between the main and passive friction plates in the device is realized by the mutual movement of the fine thread connection manual adjustment adjustment sleeve and the second support sleeve, but this test The device cannot perform the test function of the soft start condition

Description
technical field [0001] The invention relates to a liquid-viscous speed-regulating clutch, in particular to a liquid-viscous speed-regulating clutch test device capable of performing soft-start and speed-regulating double working condition simulation test functions. Background technique [0002] The hydraulic viscous clutch is based on Newton's law of internal friction, using the viscosity of the liquid or the shearing action of the oil film to transmit power, and adjusting the oil film gap to adjust the torque by controlling the oil pressure. As a new type of fluid transmission, the fluid-viscous speed-regulating clutch has broad engineering application prospects in speed regulation and energy saving of high-power fans and water pumps, and soft start of belt conveyors. [0003] The oil film in the gap of the friction pair of the hydraulic viscous speed clutch is the main object of theoretical research. Through the basic theory of fluid mechanics and numerical simulation meth...
