摘　　要：随着风力发电的持续发展,大兆瓦级齿轮箱已成为主流趋势;作为齿轮箱的关键零部件,内斜齿圈的加工需求很难通过传统的铣削设备满足。为了突破现有加工设备的限制,并提升齿面余量的一致性,本文通过NX进行内斜齿圈参数化建模,并考虑了热处理变形和齿根区域优化等因素,从而极大地提高了建模准确性。结合实践证明,经过加工后的齿轮精度和余量均满足工艺要求,这对类似零件的机械加工具有一定借鉴意义。With the continuous development of wind power generation,large megawatt gear boxes have become the mainstream.As a key part of the gear box,the machining demand of the inner helical gear is difficult to be met by the traditional milling equipment.In order to break through the limitations of the existing machining equipment and improve the consistency of the tooth surface allowance,this paper uses NX to conduct parametric modeling of the inner helical gear,and considers the factors such as heat treatment deformation and tooth root region optimization,thus greatly improving the modeling accuracy.Practice proves that the precision and allowance of the gear after machining meet the technological requirements.This study has certain reference significance for the machining of similar parts.
