Study on the Tooth Surface Generation of Spiral Involute Gear

Aiming at hobboing the cylindrical spiral involute gear,it builds a dish-shaped spiral involut gear to make it possible to hob this gear.According to the space meshing principle,the special processing method and the tooth face equations of the working tooth surface,derives the tooth foot surface of the dish-shaped spiral involute gear by means of the tooth face equations of the vitul rack.This method can generate three-demensional coordinates of points on the tooth surfaces of the the dish-shaped spiral involute gear in MATLAB,provide the precise solid model of the dish-shaped spiral involute gear with three-demensional coordinates of points on the generated tooth surfaces in Pro/E,lays a good foundation for the contact analysis and finite element analysis of the dish-shaped spiral involute gear.
