Digitalization and Meshing Performance Analysis on Tooth Surfaces of Hypoid Gear
Digitized hypoid gear’s surface model, which is constructed by NURBS method, can set free the constraints of conventional processing technique in the process of designing and manufacturing hypoid gear. The digitalization of tooth surfaces of hypoid gears consists of three parts: building large gear’s NURBS model, calculating small tooth surface’s character parameters based on actual requirements and small tooth surface’s digitalization. The digitalization of tooth surfaces can be realized by machining simulation, and the key points are how to establish equations of cutter head and grids of gear solid, and how to judge correct trace points in the process of machining simulation. With the aid of digitized model of hypoid gear, tooth contact analysis can be accomplished by regular motion of two NURBS tooth surfaces.
