油气润滑滚动轴承最佳供油量试验研究

Study on the Optimum Oil Feeding for the Rolling Bearing Lubricated with Oil-air

在自行研制的油气润滑滚动轴承的试验装置上,研究了在不同载荷下供油量变化对油气润滑滚动轴承外圈温度的影响过程。结果表明,发现随着载荷的升高,最佳供油量的数值不断增大,表明油气润滑在不同的工况条件下要采用不同的最佳供油量进行工作,才能实现最佳的油气润滑效果。

On the developed experimental rig of rolling bearing lubricated by oil-air, the influence of magnitude of oil feeding on the temperature of the out ring under different load and speed was studied. It is found that the optimum oil feeding increases with the load increase, which indicates that the oil-air lubrication can realize satisfactory result only when the rolling bearing is fed with optimum oil flow rate.
