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。
The actual shape of a spiral bevel gear is a very important factor affecting its dynamic performance. This paper introduces the scanning measurement, data processing and application method of spiral bevel gear tooth surface with virtual conjugate datum, that is, the datum surface of the gear adopts the theoretical tooth surface calculated by machine tool setting parameters, while the pinion The reference plane uses the imaginary pinion tooth surface that is conjugate to the large gear. As a result of two-dimensional probe for tooth surface measurement, effectively avoiding the friction between the probe and the tooth surface, both to maintain high accuracy, but also for rapid measurement. At the same time, this kind of measurement adopts the method of continuous scanning, which has large amount of information and high speed, and is suitable for the tooth surface quality control and control of spiral bevel gears in mass production. Because the scanning measurement adopts the virtual conjugate reference tooth surface, the position and shape of the contact spot on the tooth surface can be judged from the measured data, so that the tooth surface quality can be managed and controlled intuitively and effectively.
