新型风电增速箱齿圈销孔制造工艺研究

Research on new pin hole process for wind power gear box ring gear

增速箱齿圈是连接箱体和扭力臂的核心部件,圆周上销孔的位置度是齿圈制造工艺的一个难点。提出了一种新型的齿圈销孔加工方法,即采用卧式加工中心,并设专用的夹具进行定位。该方法在保证齿圈销孔位置度的前提下,大大提高了生产效率。

Ring gear is a core component connecting the gear box and the torque arm. It is difficult for pin holes position to manufacture process. The paper presents a new method for pin hole process,which is used to horizontal machining center and special fixture for positioning. This method can guarantee the position of the pin hole and meanwhile increase productivity greatly.
