精锻直齿伞齿轮的精度评定内容,也是由运动精度、工作平稳性精度、齿的接触规范和侧隙的结合形式组成.精锻齿轮的运动精度和工作平稳性精度主要由电极的同项精度,精锻模的电加工精度和精锻齿轮的锻后加工保证;侧隙范围主要由精锻齿轮的安装距来保证,而安装距是由锻后加工球面(或定位基准面)的 Accuracy of precision forged spur bevel gear content, but also by the accuracy of the movement, the work of the stability of precision, tooth contact specifications and the combination of backlash form.Forging precision gear forging accuracy and job stability mainly by the same electrode Precision, forging precision machining precision forging gear and after forging processing guarantee; backlash range mainly by forging gear installation distance to ensure that, and installation distance from forging processing spherical (or positioning datum)
