Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the existing optical interference film thickness measurement method based on the ball and disc cannot accurately reflect the oil film thickness state in the actual bearing, and to provide a thrust ball bearing light interference linear oil film thickness detection method, which can simulate the thrust ball bearing Complicated working conditions when placed vertically, and to detect the thickness of the oil film between the raceway and the roller at different positions, to conduct online observations of the grease supply at the entrance of the point contact area at different speeds and the evolution of the overall grease pool, and to monitor the After the test, the lubrication distribution form (grease whisker) in the bearing is measured and observed

Abstract

The invention discloses a thrust ball bearing optical interference linear oil film thickness detection method, aiming at the problem that an existing optical interference film thickness measuring method based on a ball disc cannot accurately reflect the thickness of an oil film in a bearing. The thrust ball bearing optical interference linear oil film thickness detection method comprises the stepsof: after a gap between a steel ball and a retainer is filled with lubricating grease, attaching a thrust ball bearing retainer steel ball assembly to a steel thrust ball bearing ring, so that a glass thrust ball bearing ring and the thrust ball bearing retainer steel ball assembly bear loads; then, shooting oil film light interference images between the steel ball in the thrust ball bearing retainer steel ball assembly and a raceway of the glass thrust ball bearing ring in rotating and rotation-stopping states of the glass thrust ball bearing ring by means of a microscope high-speed camera sequentially, and observing the shape of a second-phase grease pool; and finally, taking down the thrust ball bearing retainer steel ball assembly and the steel thrust ball bearing ring, shooting the morphology of grease whiskers in the raceway of the steel thrust ball bearing ring to obtain a grease whisker angle mean value. The thrust ball bearing optical interference linear oil film thickness detection method can analyze the oil film state and a backflow mechanism of base oil during actual operation of a bearing.

Description

technical field [0001] The invention belongs to the technical field of testing and relates to detection of bearing oil film thickness, in particular to a method for detection of thrust ball bearing light interference linear oil film thickness. Background technique [0002] As one of the basic components in mechanical equipment, rolling bearings have many advantages such as small sliding friction coefficient, high degree of industrial standardization, compact structure, and easy start-up. They are widely used in industry, transportation, agriculture, home appliances, aerospace, and national defense. Applications in many fields have a major impact on the development of the global machinery industry 4.0. As the most strategic basic industry in our country, it is the object of our country's focus and research. On the basis of the past 60 years of development, my country's bearing industry has already possessed considerable independent development capabilities, strong technical ...
