【 摘 要 】

A method of three-dimensional precise modelling is given based on the basic meshing principle of spiral bevel gear. With the help of the spherical involute equation and the base conic helix equation, a series of data points of tooth profile and tooth trace are calculated by programming with MATLAB, according to the known basic parameters of spiral bevel gear. Then the exact curve is generated, and it is introduced into the UG environment for modelling. Taking the automobile rear axle driven gear as an example, the concrete method of the 3D solid modelling is illustrated. It is proved that the 3D accurate modelling method is feasible and effective by its application in the measurement and evaluation of the tooth surface error of the spiral bevel gear.
