Problems solved by technology

At present, the theoretical research on liquid viscous transmission technology has achieved considerable results, but the progress in experimental research has been slow, mainly because of the lack of test devices that are easy to operate, simple in structure, and easy to detect.
Previously, CN103790998A had disclosed a double-plate fluid-viscous speed-regulating clutch, which manually adjusted the thickness of the oil film between the active and passive plates through fine threads, and adjusted the power output of the oil film. However, the adjustable range of the oil film thickness was too small. The adjustment gap is too large, the accuracy is difficult to guarantee, and the internal oil film flow state is invisible, etc.

Abstract

The invention discloses a vertical visual oil film power testing device, which mainly includes a driving force part, a liquid viscous main machine, an oil film thickness adjusting device, a support and the like. The upper box cover, the lower box cover and the support plate of the liquid viscous main engine are connected by screws to form the liquid viscous main engine casing. The sleeve passes through the upper box cover and is welded and fixed with it. The input shaft passes through the sleeve and connects to the active plate support. The friction plate is fixed on the active plate support; the passive friction plate is fixed on the passive plate support, the passive plate support is connected to the output shaft, the output shaft is connected to the fixed block of the output shaft, and is fixed on the lower box cover to keep the output shaft not Rotate, while the output shaft and the groove block are fixed by pins, the groove block is placed on the wedge-shaped slider, and the wedge-shaped slider moves by adjusting the screw to realize the vertical rise and fall of the output shaft. The invention has the advantages of convenient operation, simple structure, and easy detection, and can realize functions such as large-scale adjustment of oil film thickness, fine adjustment, visible flow state of oil film, and the like.

Description

technical field [0001] The invention relates to a testing device, in particular to a vertical visual oil film dynamic testing device. Background technique [0002] With the development of society, energy saving and consumption reduction have become a topic of common concern. The introduction of fluid viscous speed clutches into the soft start and speed regulation process of large mechanical equipment can greatly reduce equipment energy consumption and improve equipment working stability. The hydraulic viscous clutch is a device developed by applying liquid viscous transmission technology. It is a transmission device that uses liquid as the working medium and adjusts the output speed and torque by changing the thickness of the oil film between the friction pairs. . At present, considerable achievements have been made in theoretical research on liquid viscous transmission technology, but progress in experimental research is slow, mainly because of the lack of test devices tha...
