AI Technical Summary

Technical Problem

Existing heavy ball bearings suffer from increased friction, wear, higher energy consumption, reduced performance, and maintenance needs due to their weight, which compromises their efficiency and longevity, especially in high-speed applications.

Method used

The design and manufacturing process of ball bearings are modified by introducing curved profiling or corrugation over the outer and inner surfaces of the rings through a bar/tube drawing process, reducing weight while enhancing strength and cooling efficiency.

Benefits of technology

The modified ball bearings achieve up to 22%-24% weight reduction in the outer ring and 18%-20% in the inner ring, with improved fatigue strength, 40% higher load capacity, and 7% better thermal performance, leading to enhanced operational efficiency and reliability.

Abstract

The present invention discloses a light weight ball bearing with enhanced strength and cooling effect. The weight of the said ball bearing is reduced by drawing curved profiling / corrugation over the inner surface (201) of inner ring (200) and outer surface (101) of the outer ring (102) through bar / tube drawing process wherein a steel bar is converted into a hollow tube and subsequently cold drawn through a profiled die. The said technical modifications reduce the raw material / weight of outer ring by up to 22-24% and reduce the raw material / weight of the inner ring by up to 18-20%. The said profiled ball bearing has 10% increase in fatigue strength, 40% higher push / pull load capacity and 7% improvement in heat transfer efficiency, thus the said profiling enhances the strength and cooling effect of ball bearing along with weight reduction of the same.
