摘　　要：该文分析了汽车主锥中圆锥滚子轴承的预紧力与轴向位移、压紧轴承的锁紧螺母拧紧力矩之间的关系,以及轴向位移量与启动摩擦力矩之间的内在联系,并研制出具有锁紧螺母预紧力矩和轴承启动摩擦力矩自动测量功能的主锥自动装配设备的控制系统。该系统以工控机为控制核心,以VisualC++作为软件开发工具,使系统既具有较高的稳定性及灵活性,又有直观、友好用户界面。控制系统对锁紧螺母拧紧力矩和轴承摩擦力矩采用闭环控制的实时测量,可精确控制轴承的预紧力,提高主锥总成的装配质量和生产效率。The relation among the bevel drive pinion bearing preloads, axial displacement and locknut screwing moment and the relation between the frictional moments were analyzed in this article. Based on the analysis, the control system of the equipment of automatic assembling bevel drive pinion was developed, which had the function of automatic measuring screwing moment and start-up friction moment. Having industrial PC as control centre and using the software Visual C＋＋ as developmental tool, the control system can have control over the bearing preloads accurately by means of closed-loop real-time measuring screwing moment and start-up friction moment, and the assembling quality and efficiency of bevel drive pinion assembly are improved accordingly.
