axial deformation and bearing stiffness have a significant impact on the contact path direct and transmission error of spiral bevel gears.Based on the finite element analysis of contact theory
the construction methods of the model with Machining errors
assembly errors
axial deformation and bearing stiffness is given.Using a pair of hypoid gear model
the change rules of transmission error and contact path under various errors is researched.This provides an effective analysis method for the high-quality spiral bevel gear design.
