Analysis of oil⁃off tolerance of angular contact ball bearing under condition of high speed and heavy load
According to the study of the oil⁃off fault recurrence phenomenon of the angular contact ball bearing,the initial failure mode was three⁃point contact between balls and inner rings.The three⁃point contact analysis method was used to calculate the bearing's oil⁃off tolerance;in combination with the calculation and analysis results of similar bearings,it was found that the larger the shim angle,the worse the bearing's oil⁃off capacity.The bearing had poor resistance of oil⁃off when the shim angle was 25°.Through analysis of the transient temperature distribution of the bearing after the oil⁃off,combined with the three⁃point contact analysis method,it was determined that the bearing oil⁃off withstand time of the original design state was 25 s,without the ability to withstand the oil⁃off for 30 s.According to the conclusion of the analysis,the shim angle of the bearing was reduced to 19°,and the improved bearing passed the oil⁃off verifications of test rig and engine test verification.
