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.

对带纹理的滚子轴承的改进的TEHL分析考虑了各种纹理参数和滑移

目的

这项研究的目的是揭示在各种纹理尺寸，纹理深度，纹理类型和打滑情况下，纹理滚子轴承的润滑性能。

设计/方法/方法

本研究提出了一种改进的热弹性流体动力润滑方法，该方法基于带纹理的滚子轴承的表面纹理化，然后纹理尺寸，纹理深度，纹理类型和滑移对接触压力，膜厚和温度分布的影响系统地分析。

发现

结果表明，由于表面纹理化，在接触区域上压力降低并且膜厚度增加。温度随着纹理大小的增加先升高，然后降低，然后温度随着纹理深度和滑移度的增加而升高。与圆形和方形纹理相比，十字纹理可以明显降低接触区域的温度。验证了所提方法的有效性。

创意/价值

这项研究可以帮助减少纹理滚子轴承的摩擦和磨损。
