Abstract

The invention discloses a hydro-viscous drive characteristic testing system, and is applicable to simulating oil film power drive characteristic between rotary interfaces on various working conditions. The hydro-viscous drive characteristic testing system mainly comprises a base, a motor, a coupler, a torque sensor, a hydro-viscous drive device and a hydraulic control system. The hydro-viscous drive device comprises an input shaft, an output shaft, a driving friction plate, a driven friction plate, a left supporting plate, a right supporting plate, a shell, a sealing component and the like. The hydraulic control system mainly comprises a motor, a double-pump, a proportional spill valve, an electromagnetic reversing valve, a throttling valve, a flowmeter, a filter, a pressure transmitter, an oil tank and the like. The hydro-viscous drive characteristic testing device and the system are implemented according to the operation principle of utilizing shear force of an oil film between the friction plates to transmit power and regulating transmission torque by changing the thickness of the oil film or rotational speed of the motor. The hydro-viscous drive characteristic testing system is simple in structure, low in cost, convenient to operate, safe and reliable, can be used for researching on characteristics of flow field, pressure field, temperature field and transmission torque of the oil film between the rotary interfaces on various working conditions, and has practicability in a wide scope.

Description

technical field [0001] The invention relates to a fluid-viscous transmission characteristic testing system, which is especially suitable for simulating the power transmission characteristics of oil films between rotating interfaces under various working conditions, and studying the flow field, pressure field, temperature field and transmission torque of oil films between rotating interfaces, and is a liquid-viscosity test system. Provide certain technical support for the design of the transmission device and the application and promotion of hydroviscous transmission technology. Background technique [0002] Using the viscosity or shearing action of liquid to transmit torque, also known as liquid viscous transmission (referred to as liquid viscous transmission), is a new form of fluid transmission developed from abroad in the mid-1970s. It is based on Newton's law of internal friction, The transmission torque is controlled by changing the thickness of the oil film. It is char...
