Gear hobbing accuracy

Under extremely complex conditions, the bearing capacity, service life, safety and meshing tooth surface contact behavior of high-performance gear transmission are directly related to the macro and micro morphology and microstructure distribution of gear matrix and tooth surface. Therefore, the design requirement of controllable micro morphology and texture of...
