静压轴承就是由外部把润滑油强制地打入轴承间隙内,形成油膜,由油膜的静压来支承负载的轴承。这样,尽管轴承的二个面之间完全没有相对运动,也可保持其润滑状态。由于由外部供给高压油,所以它就可以具有较高的承载能力。这种轴承使轴与轴承由油膜完全分离开,所以轴承的摩擦阻力很小,尤其是起动摩擦阻力几乎等于零,它具有适于高速运转,较低的轴承运转温度,较好的减震性等优点。因此,近年来已引起人们的广泛注意。
Hydrostatic bearings are forced by the external oil into the bearing clearance, the formation of oil film, the static pressure from the oil film to support the load bearing. In this way, even though there is absolutely no relative movement between the two faces of the bearing, it can maintain its lubrication state. Because of the external supply of high-pressure oil, so it can have a higher carrying capacity. This bearing shaft and bearing completely separated from the oil film, so the bearing frictional resistance is very small, especially the starting frictional resistance is almost equal to zero, it has suitable for high speed operation, lower bearing operating temperature, better shock absorption, etc. advantage. Therefore, in recent years, people have drawn wide attention.
