摘　　要：分析了汽车驱动轴锁紧螺母拧紧时,驱动轴螺旋花键与轮毂轴承直齿花键配合过盈量过大导致的轮毂轴承与驱动轴装配不贴合以及螺纹滑牙等问题。使用带扭矩传感器及角度传感器的伺服拧紧枪进行拧紧并实时采集数据,采用正转角度监控以及反转扭矩监控等拧紧监控策略进行监控,实现驱动轴螺母拧紧失效的100%检出。When the locking nut of the drive shaft is tightened,it may brings some problems,such as hub bearing is not fitted with the driver shaft and the sliding tooth fault occurrs,because the magnitude of interference between the drive shaft helical spline and hub bearing straight spline is too large.By using the tighten tools with torque sensors and angel sensors,we can set forward tightening strategies with angle monitoring and reverse loosening strategies with torque monitoring to identify problems fully in real time.
