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