Angular Contact Ball Bearing Friction Torque Fluctuation Analysis

For low friction moment angle contact ball bearing, using energy conservation, research angle contact ball bearing parts work surface of corrugated degrees on bearing friction moment fluctuations sex of effect, from theory diagonal contact ball bearing parts work contact surface of corrugated degrees site value, and harmonic order times and bearing friction moment fluctuations sex of relationship for analysis, to out effect angle contact ball bearing friction moment fluctuations sex of within, and outside roll road and steel ball work surface of main corrugated degrees harmonic order times and corresponding of stress vibration frequency, and test validation. Research results showed that: both inside and outside rings roll road of kZ times, and kZ/2 times harmonic and two species different harmonic of and or of poor is equal to kZ times of harmonic order times is incentive angle contact ball bearing friction moment fluctuations sex of main harmonic order times, outside roll road incentive harmonic corresponds to of stress vibration frequency for kZ (NC NE), within roll road incentive harmonic corresponds to of stress vibration frequency for kZ (NI NC); steel ball work surface corrugated degrees of I times harmonic diagonal contact ball bearing of friction moment fluctuations sex up incentive role, Steel ball surface waviness of the odd harmonics of the angular contact ball bearing friction torque fluctuation will not affect excitation corresponds to the harmonic frequency of the steel balls for 2 KNB. Study on the processing technology of angular contact ball bearings for low friction moment parameters controlling ...
