Slicing Technology for Cylindrical Gears

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.
