The Measurement and Evaluation Method of Global Error of Spiral Bevel Gear
This paper offers a method of spiral bevel gear’s global error measurement and evaluation based on three-coordinate measurement according to the characteristics of spiral bevel gear. The 3d solid modeling built in UG was regarded as the gear’s ideal factor of measure and error evaluation; the values of the measured points in the real gear tooth surface by CMM were regarded as the gear’s real factor. The global error of spiral bevel gear was reflected by the difference surface which was fitted by the deviation between real tooth surface and theoretical tooth surface. This method is very effective and feasible by measuring and evaluating the automobile rear axle’s driven gear.
