Problems solved by technology

However, in the actual working state of rolling bearings, the motion state becomes more complicated due to the revolution and rotation of the balls, especially when the angular contact bearings are running at high speed, the balls include a certain degree of spin motion in addition to rolling and sliding
However, the existing measuring devices can only simulate the specific working conditi

Abstract

The invention provides a simulation experimental apparatus for a lubrication condition of an antifriction bearing and a measuring method thereof. The apparatus comprises an operating platform; a drive unit is arranged on the operating platform and is used for driving an elastodydrodynamic contact couple unit; and the elastodydrodynamic contact couple unit is connected with a loading unit; meanwhile, the elastodydrodynamic contact couple unit and an optical measurement unit are cooperated with each other. According to the measuring method of the apparatus, the method comprises the following steps that: a preparation process, a localization and adjustment process for an antifriction bearing; a driving process; and a measurement analysis process. A motion state of the antifriction bearing can be observed directly; simultaneously, a lubrication state of a lubrication oil film in the antifriction bearing are measured and analyzed, so that experimental data are provided for a theoretical research and improvement on an engineering technology.

Description

technical field [0001] The invention belongs to the field of lubricating oil film measurement of high-stress contact fluids, in particular to an experimental device and method for measuring lubricating oil film under real motion conditions of rolling bearings. Background technique [0002] In practical engineering, rolling bearings are widely used. In the 1930s, the combination of Reynolds lubrication theory and Hertz contact theory led to the rapid development of research on the lubrication mechanism of rolling bearings. In the basic research field of lubrication theory, researchers tend to use the most concise mathematical model to respond to more complex lubrication problems and reveal the lubrication mechanism. Existing measuring devices for high-stress lubricating oil film are almost all based on figure 1 The mathematical equivalent model is shown, whereby the contact mode between the ball and the inner and outer rings of the bearing is equivalent to the contact betwe...
