带油槽的轴承轴心轨迹研究

On Calculating the Journal Center Orbit of a Bearing with a Semi-Circumferential Groove

本文就部分周向油槽轴承轴心轨迹计算作了简单介绍,提出一种新的计算方法。通过对有槽轴承和无槽轴承压力分布的比较,明显地看出有槽轴承承载能力削弱了。如果油槽按本文建议开设,那末最小油膜厚度基本上不会减薄。

In this paper,a new method for calcuating the journal center orbit of a bearing with a semi-circumferential oil groove is presented.By comparing the plessure distributions in both bearings with and without oil groove,it is found that the load capacity of the bearing with an oil groove decreases apparently,Computational results show that a easonally located partially-circumferential oil groove will not obviously reduce the minimum oil film thickness of the bearing.
