摘　　要：推导了双列角接触球轴承径向游隙、轴向游隙、接触角和沟心距及原始径向游隙之间的相互关系 ,给出了双列角接触球轴承内、外圈沟心距及公差的确定方法。利用该方法 ,在轴承合套时 ,不用对沟心距进行分组就能保证1 0 0 %的合套率。附圈 2幅 ,表 2个。The correlations between radial clearance,axial clearance,contact angle and groove center distance,original clearance have been infered for the double row angular contact ball bearings.The determining method for groove center distance of inner ring,outer ring and its tolerance of double row angular contact ball bearing has been given. Using this method, 100% qualified assembly ratio could be achieved,without grouping rings the groove center distance during the bearing assembly .
