An improved TEHL analysis of textured roller bearings consider various texture parameters and slip

Abstract

Purpose

The purpose of this study is to reveal the lubrication performance of textured roller bearings under various texture size, texture depth, texture types and slip.

Design/methodology/approach

In the present study, the improved thermal elastohydrodynamic lubrication method based on the surface texturing of the textured roller bearings is proposed, and then the effect of texture size, texture depth, texture types and slip on the contact pressure, film thickness and temperature distribution are analyzed systematically.

Findings

The results show that the pressure decreases and the film thickness increases on the contact area because of the surface texturing. The temperature increases first and then decreases as the texture size increases, and then the temperature increases as the texture depth and the slip increases. Compared to circle and square texture, cross texture can obviously decrease the temperature on the contact area. The effectiveness of the proposed method is verified.

Originality/value

This study can help to reduce friction and wear of textured roller bearings.
