1 引言要对锥齿轮加工过程进行控制,并且确定齿轮箱中各齿轮付的传动比,先决条件是能够对锥齿轮的实际齿形进行精密测量,而且还应具有高度的重复性。到目前为止,在锥齿轮或锥齿轮付的实际测量方面,所采用的测量方法(如单面啮合方法和接触斑点方法)主要是测定其综合误差。由于各种锥齿轮的齿形都很复杂,并且彼此间差异很大——这取决于锥齿轮的各种不同的加工方法,迄今只有在特殊情况下,而且要相当大的费用才有可能对锥齿轮作单项误差测量。鉴于对齿面名义几何形状按点进行计算的
1 Introduction To control the bevel gear manufacturing process and to determine the gear ratios delivered by the gears in the gearbox, the prerequisite is a precise measurement of the actual gear shape of the bevel gear and a high degree of repeatability. So far, the measurement methods used for the actual measurement of bevel gears or bevel gears, such as the one-side meshing method and the contact spot method, have mainly been to determine their combined errors. Due to the complexity of the tooth profiles of the various bevel gears and their wide variations from one another, depending on the various processing methods of the bevel gears, it has so far been possible only in exceptional circumstances and at considerable expense Bevel gear for single error measurement. In view of the nominal surface geometry of the point-by-point calculation
