摘　　要：针对推力圆柱滚子轴承工作过程中滚子两端线速度不同引起的滚动体打滑、温度升高等现象,结合双列推力圆柱滚子轴承的结构特点,对滚动体布置方式及保持器结构进行优化,提出两种优化方案。优化后轴承充分利用轴承内部空间,且改善因滚动体两端线速度不同导致的回转不平稳现象;优化后轴承与同尺寸的传统轴承相比,具有承载能力高、结构紧凑、回转稳定性好,且部分零件能通用等优点。In view of the phenomenon of rollers skid and temperature rise caused by different roller velocity at both ends of thrust cylindrical roller bearing in working process,combining with the characteristics of the structure of double row cylindrical roller thrust bearing,the rolling element arrangement and retainer structure are optimized,and two optimization schemes are put forward.It makes full use of the internal space of the optimized bearing.It also improves the rotation instability caused by different linear velocities at two ends of the rolling body.Compared with the traditional bearing of the same size,the optimized bearing has the advantages of high load capacity,compact structure,good rotation stability,and some parts can be used in general.
