摘　　要：以WR3258152型汽车水泵轴承为研究对象,通过全面考虑各种影响因素,建立了计算实际工况下该轴承所承受载荷的公式,并根据所计算的载荷,运用Lundberg-Palmgren寿命理论对该轴承的寿命进行了计算,结果表明,WR3258152型汽车水泵轴承中的两列滚动轴承未能实现等强度设计,寿命差距较大。The WR3258152 automotive water-pump bearing is investigated.After considering various influencing factors comprehensively,the suitable calculation models are summarized and developed.The water-pump bearing＇s life is also predicted with the Lundberg-Palmgren method according to the results of the specific load calculations.The life calculation shows that the two rows of rolling elements of the WR3258152 water-pump bearing have difference in life,which means that they did not realize equal strength requirement.
