Study on contact stress of cylinder gear and tooth profile modification of offset press

Abstract

The cylinder gear is an important part of offset press. It has great significance to ensure the speed of the cylinder gear constant and stable. In this paper, the finite element analysis software ANSYS is used to analyze the gear tooth deformation on influence of gear meshing transmission performance, and it comes to the conclusion that the gear before modification exists interference and stress concentration phenomenon. Adopting a method of cylinder gear-tooth profile modification for gear tooth, it shows that the gear tooth interference and the stress concentration phenomenon disappear after the modification, the gear-bearing capacity is greatly improved, and the gear runs more smoothly.
