高铁圆锥滚子轴承滚子与滚道间的接触分析
Contact analysis between roller and raceway of tapered roller bearing of high-speed rail
摘要
Abstract
Based on Hertz contact theory and roller strip theory,this paper has made the numerical analysis on contact properties between roller with different convexities and raceway of tapered roller bearing of high speed rail.The contact stress and contact load calculation models between roller and raceway are established and the example analysis is made on CRH3 high-speed rail (HSR) axle box bearing and the stress and load distribution in the direction of roller generatrix are solved and the optimal roller crowning of logarithmic curve roller is calculated under the condition of full load.Results show that the degree of stress concentration on roller is associated with the magnitude of load,logarithmic profile of roller can only reduce and fails to eliminate the stress concentration,the optimal roller crowning is lightly less than theoretical convexity.关键词
