螺旋锥齿轮齿面扫描式测量法及其应用研究

螺旋锥齿轮的实际齿面形状是影响其动力学性能的一个非常重要的因素。本文介绍了采用虚拟共轭基准面的螺旋锥齿轮齿面的扫描式测量、数据处理及应用方法，即大齿轮的基准面采用的是由机床设定参数计算出的理论齿面，而小齿轮的基准面采用的是与大齿轮共轭的假想小齿轮齿面。由于采用了二维测头进行齿面测量，有效地避免了测头与齿面间摩擦力的影响，既能保持高精度，又能进行快速测量。同时，该种测量采用连续扫描的方法，信息量大、速度快，适合于大批量生产中的螺旋锥齿轮的齿面质量管理与控制。由于扫描式测量采用了虚拟共轭基准齿面，所以从测量数据本身就可以判断齿面的接触斑点位置与形状，因而可以直观、有效地对齿面质量进行管理与控制。

Surface error measurement of spiral bevel gears using scanning measurement

The gear tooth flank form is a very important factor to dynamic performance of spiral bevel gears. The scanning measurement method is developed to measure tooth flank form using virtual conjugate reference tooth flank. In this paper the usage of this method and the data processing method for spiral bevel gears are introduced. The wheel reference tooth flank is the theoretical tooth flank calculated by machine setting, and the pinion reference tooth flank is the conjugate one to the wheel reference tooth flank. Because the scanning measurement machine uses a 2D senor, so the bad influence of friction between the probe and tooth flank on the measured results can be avoided,therefore the scanning measurement has great information and enables quick, fully automated high precision measurement of tooth profile and lead. The method is suitable for control and management of tooth flank form quality of spiral bevel gears for mass production. Because the scanning measurement makes use of virtual conjugate reference tooth flank, the shape and location of tooth contact pattern can be directly judged from measured tooth flank form data, and the control and management of the tooth flank form quality can be carried out visually and effectively.
