摘　　要：为了满足新能源汽车电机高转速和大扭矩的设计要求,文章在输入轴上采用了整体式四点接触球轴承代替普通深沟球轴承的设计思路,利用Masta软件分析轴承受力及寿命情况,并通过台架和整车进行试验验证,计算结果与实验情况符合较好,满足客户使用要求,这说明四点接触球轴承在能源减速器高速轴上的应用是可行的。In order to meet the design requirements of high speed and high torque of new energy vehicle motors,this paper adopts the design idea of integral fourpoint contact ball bearings instead of ordinary deep groove ball bearings on the input shaft,uses Masta software to analyze the bearing force and life,and verifi es the test through the bench and the whole vehicle,and the calculation results are in line with the experimental situation to meet the requirements of customer use,which shows that the application of four-point contact ball bearings in the high-speed shaft of energy reducer is feasible.
