Vertical visual oil film power test device

Abstract

The invention discloses a vertical visual oil film power test device, which mainly comprises a prime power part, a liquid viscosity host machine, an oil film thickness regulating device, a support seat and the like, wherein an upper box cover, a lower box cover and a support plate of the liquid viscosity host machine are connected through screws to form a liquid viscosity host machine case, a sleeve passes through the upper box cover and is fixed with the upper box cover through welding, an input shaft passes through the sleeve to be connected with a driving sheet support seat, a driving friction sheet is fixedly arranged on the driving sheet support seat, a driven friction sheet is fixedly arranged on a driven sheet support seat, the driven sheet support seat is connected with an output shaft, the output shaft is connected with an output shaft fixing stop block and is fixedly arranged on the lower box cover, the output shaft is maintained not to rotate, meanwhile, the output shaft is fixed with a groove block through a pin post, the groove block is arranged on a wedge-shaped slide block, the wedge-shaped slide block moves through regulating a lead screw, and the ascending and the descending of the output shaft in the vertical direction are realized. The vertical visual oil film power test device has the advantages that the operation is convenient, the structure is simple, the detection is easy, and the functions of wide-range oil film thickness regulation, fine regulation, visible oil film flow state and the like can be realized.

Description

technical field [0001] The invention relates to a testing device, in particular to a vertical visual oil film dynamic testing device. technical background [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. [0003] 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 de...

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.
