Improved four point contact ball bearing in two races and an improved dresser to manufacture the same

Abstract

Problem to be solved by this Invention is to manufacture an Actual Four Point Contact Ball Bearing which reduces a self friction of Bearing by 50% in compared to Deep Groove Ball Bearing. Actual Four Point Contact Ball Bearing comprises an inner race (b1), an outer race (a1), balls (d11) & cage wherein inner race & outer race have a groove made up of two circular arcs forming a Gothic arch in which Balls are accommodated & kept in position with the help of cage. In this invention the balls have a point contact at 35° (c1) with races in groove forming a gothic arch. Actual Four Point Contact Dresser comprising a Base, a Stand, a Handle, a Bearing Assembly, a Cylinder, a Piston, a Gothic Arch Guide Plate, a Lever and a Diamond which in operation dresses a Grinding wheel in Gothic Arch Formation resulting in Grinding of Gothic Arch Grooves of Outer & Inner Races of Actual Four Point Contact Bearing.
