Influence of Technical Parameters on Contact Pressure in Straight Bevel Gear Meshing

Abstract:

Wear is one of the main failure modes of gears in the meshing performance, and contact pressure is the key factor to determine the wear of gears. The main purpose of this paper is to investigate the contact pressure distribution and evolution laws in straight bevel gear meshing. Based on a 3D FE model of the specific loaded assembling straight bevel gear pair, the influence of friction coefficient f, torque T and elastic modulus E on the contact pressure of straight bevel gear in a meshing circle is studied. The results show that the contact area and contact pressure increase dramatically with the increase of the torque. The contact area decreases and the contact pressure increases with the increase of elastic modulus. Friction coefficient almost has no effect on the contact area and contact pressure. This research has great theoretical significance to reveal the wear mechanism and improve the meshing performance of straight bevel gears.
