Loss Reduction of Rolling Bearings for Automobile

Abstract

The role of rolling bearings is to support rotational motion with low friction. Although the friction is low in rolling bearings, it does not mean that friction does not occur at all. Many rolling bearings are used in automobiles. Therefore, if it is possible to reduce the friction loss in the rolling bearings, it can contribute to reducing the fuel consumption of the automobile. In this paper, we introduce representative techniques for reducing the friction in automotive bearings.

An Experimental and Numerical Evaluation of Seal Strictness on Ball Bearing Performance

“…T.Sada and his colleagues examined friction loss reduction of ball bearings [4]. Ł.Gorycki and his colleagues analyzed the impact of the cage type on the frictional moment of ball bearings and showed that the type of cage used in ball bearings has a significant impact on the frictional moment [5].…”

“…As friction force increases, ball bearing life decreases [4]. Theoretically, we have 2 main equations to calculate the friction force [10].…”

An Experimental Study of Surface Damage on Rolling Bearings in Low Lambda Conditions

“…Rolling bearings have seen fast progress in manufacturing and design over the last decade, with broad usage in a variety of sectors [1][2][3][4][5]. It is widely accepted that the application of rolling bearings has advantages in terms of reducing cost, size, weight, and friction.…”
