For small-module spiral bevel gear

a new machining process is proposed.The pinion is adopted traditional double-side machining method.Designing gear machining parameters

the gear two tooth surfaces are controlled separately to suit for pinion tooth surface.According to above machining process

small-module spiral bevel gear machining parameters are designed to fulfill good meshing property

and its accurate 3D model is created.Under UG software environment

the gear virtual assembly and interference checking are completed.The small-module spiral bevel gear tooth surfaces are designed to have good meshing property

and the 3D model can be applied for the gear molding machining process

such as powder metallurgy

precision forging

injection molding

etc.The above research provided a theoret ical foundation on small-module spiral bevel gear precision

high efficiency and energy saving manufacturing.Key words Small-module Spiral bevel gear 3D model Molding machining process
