摘要
基于Houpert给出的赫兹点接触椭圆参数及弹性变形量的计算公式,在进行力学分析的基础上,建立了一个考虑滚子直径误差联合载荷作用下球面滚子轴承(SRB)滚子-滚道点接触法向载荷及轴心轨迹的计算模型,并用算例研究了单个滚子存在直径误差与多个滚子存在直径误差对球面滚子轴承滚子载荷及轴承轴心轨迹的影响.计算结果表明:滚子存在正的直径误差时,其最大载荷将增大;滚子存在负的直径误差时,其最大载荷将减小;滚子的直径误差将极大地影响球面滚子轴承的轴心轨迹.
Based on the calculation formulae for Hertz-point contact elliptical parameters and elastic deformation values from Houpert,the mechanical analysis is conducted.A calculation model,including contact normal loading among spherical roller,bearing roller and tray point and axis track,is established under combined loading with roller diameter errors.In addition,the impacts of single and multiple roller diameter errors upon roller loading and axis track are speculated using computational cases.As such,it is indicated that the maximum roller loading increases while the positive roller diameter error exists.On the contrary,the maximum roller loading decreases while the negative roller diameter error occurs.In addition,the roller diameter error significantly impacts the roller axis track.
