摘要

为了降低空调滑片式压缩机的摩擦功耗，对其所用圆柱滚子轴承的摩擦功耗特性进行了研究。基于滚动轴承动力学理论，考虑周期性载荷因素，建立了压缩机用圆柱滚子摩擦功耗数学模型，在此基础上分析了轴承工况参数和结构参数对圆柱滚子轴承摩擦功耗特性的影响规律。研究结果表明：在满足轴承使用要求前提下，选取较大的径向游隙有利于降低轴承的摩擦功耗；圆柱滚子轴承存在合理的保持架引导间隙和保持架兜孔间隙，使得轴承摩擦功耗最小；随着滚子个数增加，轴承摩擦功耗增加，在保证轴承承载能力前提下，可以适量减少滚子数量，以降低轴承摩擦功耗；新型滑片式压缩机摩擦功耗比传统型降低了39%.

Abstract

In order to reduce the frictional power loss of air-conditioning vane compressor, based on the dynamics theory of rolling bearing, a frictional power loss model of cylindrical roller bearing for air-conditioning vane compressor is established considering the periodic load factor. The influences of working condition and structural parameters on the frictional power loss characteristics of cylindrical roller bearing were analyzed. The results show that a larger bearing radial clearance is beneficial to reduce the frictional power loss under the certain conditions. The frictional power loss can be minimized by using reasonable cage guiding clearance and cage pocket clearance. The frictional power loss of bearing increases with the increase in the number of rollers. The number of rollers can be reduced to decrease the frictional power loss of bearing within the loading capacity of bearing. The frictional power loss of the improved vane compressor is 39% less than that of the conventional ones. Key
