Effect of adjustment parameters of machine tool cutting on tooth contact of spiral bevel gear

The adjustment parameters of machine tool cutting play an important role in the tooth contact of spiral bevel gear. How to optimize the adjustment parameters of machine tool cutting and establish the calculation model of gear load distribution and load distribution are the main contents

(1) Based on the spatial meshing principle, the meshing state of spiral bevel gear is analyzed, the adjustment parameters of machine tool cutting are optimized, and the initial clearance of tooth surface and possible contact point pairs are accurately calculated.

(2) Based on the theory of elasticity and finite element, the finite element model of spiral bevel gear contact calculation and the algorithm of finite element mesh generation are established.

(3) The three-dimensional contact finite element method is used to analyze the load distribution between the teeth, the load distribution on the tooth surface and the change of the shape of the contact zone.
