国内航空发动机传动机构中高精度的圆柱齿轮的齿型基本上采用理论渐开线作为其设计齿型。为了满足更高的传动要求,在部分齿轮上也采用了渐开线修缘齿型(见图1a)。精磨齿型的手段主要是用瑞士MAAG磨齿机。
The gear type of the high-precision cylindrical gear in domestic aero-engine transmission basically adopts the theoretical involute as its design tooth shape. In order to meet the higher transmission requirements, some of the gears are also involute involute type (see Figure 1a). The main means of grinding gear type is Switzerland MAAG gear grinding machine.
