Abstract

The invention discloses a harmonic reducer wave generator hybrid lubrication analysis method in the field of hybrid lubrication analysis, and the method comprises the following steps: establishing a Reynolds equation through taking the density of a lubricant in linear contact with the outer wall of a wave generator and the inner wall of a flexible gear, distribution pressure in a solution domain,oil film thickness, object surface speed and lubricant viscosity as parameters; solving the numerical value by adopting composite iteration; establishing an equivalent lubrication model, a relation model of a film thickness ratio and an influence factor, and calculating an equivalent curvature radius, an equivalent load and a relative movement speed, so the problem that the existing analysis method cannot accurately and effectively analyze the mixed lubrication between the inner wall of a flexible gear and the outer wall of a wave generator in the XB-60-100 type harmonic reducer is solved.

Description

technical field [0001] The invention relates to the field of mixed lubrication analysis, in particular to a method for analyzing mixed lubrication of a wave generator of a harmonic reducer. Background technique [0002] It is estimated that 1 / 3 to 1 / 2 of the world's energy is currently consumed in various forms of friction. In general machinery, parts scrapped due to friction account for about 80% of all failed parts. Lubrication is one of the effective measures to reduce friction and wear. Using modern lubrication technology can greatly save energy and improve the service life of mechanical parts. In the mixed lubrication state, both hydrodynamic lubrication and asperity peak contact exist, so the performance analysis of mixed lubrication has been a difficult point for a long time. The traditional mixed lubrication analysis method usually calculates the minimum oil film thickness or the center oil film thickness, and uses this to measure the quality of the lubrication sta...
