INVESTIGATION OF THE EFFECT OF FRICTION FORCE ON DAMAGE FORMATION IN SPUR GEARS

Abstract

Gears are perhaps one of the important components used in machinery to transmit motion and power. Transmission of force and motion occur at the same moment for mutual working gears. Transmission of the force and motion from a gear to another is a result of rolling-sliding contact of tooth surfaces each other. This rolling-sliding contact causes some stresses on surface and subsurface. In this study, analysis of stresses on surface and subsurface due to rolling-sliding contact on tooth surfaces are carried out. In the solution of the problem, different friction coefficients between tooth surfaces and are taken as the variables. The contact analysis between tooth surfaces is based upon Hertz elastic contact theory and for the numerical solution ANSYS 54 finite element program code is used.
