Study on contact load and preload characteristics of cylindrical roller bearings with triple-lobe raceway

The suitable preload design of cylindrical roller bearing with triple-lobe raceway can avoid effectively sliding damage. To realize the characteristics analysis bearing, quasi-static numerical model is established and solved by improved Newton-Raphson method. Taking a as an example, effects mounting radial clearance, outer waveform value, load rotational speed on maximum contact are analyzed. results show that be controlled adjusting clearance value according to conditions. temperature trend predicted characteristic verified test. It indicates guide quantitative raceway.
