Rolling element bearings are widely used in the industry and automobiles. Contact area between the races and balls plays an important role for the formation of elastohydrodynamic lubricant film. Formation of elastohydrodynamic lubricant film is the deciding factor for the life of the bearing. To increase the life it is important to maintain the lubricant film between the ball and races. Hertz has given the idea to calculate the contact area. Aim of this present paper is to calculate the elliptical and circular contact area for the rolling element bearing 6007, 6207, 6307&6407 at different load. And comparison is also made for elliptical and circular contact area.

Abstract


Rolling element bearings are widely used in the industry and automobiles. Contact area between the races and balls plays an important role for the formation of elastohydrodynamic lubricant film. Formation of elastohydrodynamic lubricant film is the deciding factor for the life of the bearing. To increase the life it is important to maintain the lubricant film between the ball and races. Hertz has given the idea to calculate the contact area. Aim of this present paper is to calculate the elliptical and circular contact area for the rolling element bearing 6007, 6207, 6307&6407 at different load. And comparison is also made for elliptical and circular contact area.
