摘要：基于滚动轴承动力学理论，建立了三溉波滚道圆柱滚子轴承的动力学分析模型，并以某型号三瓣波滚道圆柱滚子轴承为例，分析了不同滚道结构与工况参数下的轴承载荷分布。结果表明：三瓣波滚道圆柱滚子轴承的承载范围随滚道轮席最低点半径及滚道轮廊高低点间差值的增大而减小；随着滚道轮席最低点半径所在基圆圆度的增加，滚子与滚道间的总接触载荷变化很小，最大滚动体载荷逐渐增加；随着外圈安装旋转角的增大，
滚子与滚道间的总接触载荷基本不变，最大滚动体载荷逐渐减小，滚子与滚道间的载荷分布更加均匀。关键词：圆柱滚子轴承；三波滚道；动力学；结构参数；载荷分布

Abstract: The dynamics analysis model for cylindrical roller bearings with trilobe raceways is established based on dy-namics theory of rolling bearings. Taking a certain type of cylindrical roller bearings with trilobe raceways as an exam-ple, the load distribution of bearings with different structures of raceways is investigated under different operating condi-tion parameters, The results show that the range for carrying capacity of cylindrical roller bearings with trilobe raceways is decreased with the increase of radius of raceway profile at the lowest point and difference between high and low point of raceway profile. With the increase of roundness of base circle at the lowest point, the total contact load between roll-ers and raceways changes little, and the maximum rolling element load increases gradually. With the increase of instal-lation rotation angle of outer rings, the total contact load between rollers and raceways barely changes when the maxi-mum rolling element load decreases gradually, and the load between rollers and raceways has a more uniform distribu-tion.
