Purpose

Under the influence of loading, manufacturing, installation and other factors, the axis of sleeve bearing and journal will not be aligned, which will have a great impact on running stability and life of bearing. The existence of oil groove can effectively improve the life of sleeve bearing and working efficiency. The lubrication performance of two and three grooves sleeve bearing considering journal misalignment is analyzed.

Design/methodology/approach

To solve the difference of discontinuous position of oil film thickness, it is necessary to use the flow balance relationship in the finite control space, and oil film thickness equation of multi-groove sleeve bearing considering journal misalignment is gained.

Findings

The friction and bearing capacity of journal bearing with oil groove increase with the increase of journal inclination angle. At the same journal inclination angle, the bearing capacity of two-axial groove journal bearing is larger than that of three-axial groove journal bearing, but the friction of two-axial groove journal bearing shows the trend of the first bigger and then smaller than that of three-axial groove journal bearing.

Originality/value

The research has great significance to optimize bearing lubrication performance and increase bearing working life.

考虑轴颈不对中的多槽滑动轴承润滑性能分析

目的

在载荷、制造、安装等因素的影响下，滑动轴承与轴颈的轴线不会对齐，这将对轴承的运行稳定性和寿命产生很大影响。油槽的存在可以有效提高滑动轴承的寿命和工作效率。分析了考虑轴颈不对中的二槽和三槽滑动轴承的润滑性能。

设计/方法/方法

为了解决油膜厚度不连续位置的差异，需要利用有限控制空间中的流动平衡关系，得到考虑轴颈不对中的多槽滑动轴承油膜厚度方程。

发现

带油槽的轴颈轴承的摩擦和承载能力随着轴颈倾角的增加而增加。在轴颈倾角相同的情况下，两轴槽轴颈轴承的承载能力大于三轴槽轴颈轴承，但两轴槽轴颈轴承的摩擦力呈先大后小的趋势。三轴向槽轴颈轴承。

原创性/价值

该研究对优化轴承润滑性能、提高轴承工作寿命具有重要意义。
