Problems solved by technology

However, for the sensitivity test of related static pressure devices, it is difficult to measure the small friction force with high sensitivity. In the past, it could only be tested by experienced people. There are many uncertain factors such as personnel differences, emotional factors, etc. Perceptual judgment
No quantitative judgment on its flexibility

Abstract

The invention provides a method used for measuring the frictional torque of a hydrostatic bearing and other hydraulic devices. The invention provides the highly-sensitive method for measuring the magnitude of the frictional torque of the hydrostatic bearing device in a working condition. The measurement of large frictional force is generally simple, while the measurement of small highly-sensitive frictional force of the hydrostatic bearing and the like is difficult. The method provided by the invention can meet the measurement need of the devices. According to the invention, a simple method is used to accurately measure high-precision design; accurate performance evaluation is realized; the work efficiency is improved; through the application of a period of time in actual work, a large number of test data are acquired; the performances of the hydrostatic device are objectively reflected; and compared with a previous empirical perception method, the effect of the method is more obvious.

Description

technical field [0001] The invention is a method with high sensitivity for measuring the friction torque of hydraulic devices such as hydrostatic bearings. Background technique [0002] The hydrostatic bearing is provided with pressure oil from an external lubricating oil pump to form a pressure oil film to bear the load. The friction pairs are separated by the pressure oil film during start-up and operation, and the sliding resistance comes only from the fluid viscosity. The friction factor is small, the working life is long, and the stability is stable. high sex. Hydrostatic bearings are suitable for a wide range of working conditions, ranging from precision instruments with loads measured in grams to heavy equipment with loads of thousands of tons. With the great improvement of hydrostatic bearing technology in recent years, it is also widely used in high-performance hydraulic test benches. However, for the sensitivity test of related static pressure devices, it is diff...
