摘要: 为满足航空、航天、汽车、风能等行业发展对特殊结构齿轮的需要,针对现有齿轮加工方法无法完成非贯通、无退刀槽内斜齿加工的问题,提出一种全新概念的齿轮加工方法——剐齿。从齿轮切削加工的实现、切屑的形成、切屑的排出等角度出发,给出剐齿概念和剐齿加工的特点。依据相错轴螺旋齿圆柱齿轮啮合原理,解释剐齿加工原理。根据剐齿原理,确定剐齿加工所需运动,并推导各个运动之间的关系,建立剐齿加工运动模型。应用微分几何知识,推导切削点处的相对运动速度,分析相对运动速度的影响因素,证明剐齿切削实现的可行性。利用自行设计的数控剐齿机床和刀具进行加工验证。最后给出结论,提出需要进一步展开的研究工作。

Abstract: To meet the requirements of the special structure of gear in aviation, aerospace, automotive, wind energy and other industry, a new method of gear machining, gear slicing, is proposed to improve the limitation of current gear machining method for not run-through inner gear without recess. The concept and characteristics of gear slicing are proposed in view of the realization of gear machining, chip formation, and the exclusion of chip. The principle of gear slicing is opened out based on the meshing principle of staggered axial helical gears. According to the principle of gear slicing, the movements required in gear machining and the relationship between the movements are made certain. So the movement model is established. The relative speed at cutting point is learned and the factors affecting the speed are analyzed to prove the feasibility of gear slicing based on the knowledge of differential geometry. A machining practice is performed using the slicing machine tool and slicing cutter designed by self to prove the feasibility of gear slicing again. Finally, the conclusion is made and the topics of further research are pointed out.
