国产数控机床加工风电齿轮箱体轴承孔研究

Study of Manufacturing Wind Gear Box by Using Local NC Boring Machine

介绍了2.5MW风电行星式齿轮组合箱体轴承孔设计要求,国外与国内加工风机齿轮箱条件的不同,阐述了如何用国产数控设备加工出高精度和高位置度轴承孔的齿轮箱体的方法。

This paper introduces the design requirement of the gear holes on the 2.5 MW wind gear box along with the difference in design and manufacturing of the NC machine between America and China. It gives the method to meet the design requirement of manufacturing these gear holes with tight true-position by using the domestic made boring NC machines.
