一般小孔节流式静压轴承的进油都是经过与油腔数量相同的油路,通过各自的节流器进入油腔。结构比较复杂,制造和维修也不方便。我们设计了一种进油路较为简单的四油腔静压轴承,见附图。其各参数的选取与一般静压轴承完全相同,所不同的是四个油腔只用了一根进油管,四个节流器就加工在轴承体上。压力油从进油管压入沉割槽内,沉割槽加工在轴承体外圆周上(也可加工在压入轴承体的箱体孔内圆周上),分别从轴承体上的四个节流器进入油腔。我们曾耽心过节流器加工在轴承体上,经过长时间的使用,由于压力油的流动摩擦,节流小孔是否会
The general small orifice throttling hydrostatic bearings into the oil through the same number with the oil chamber, through their respective throttle into the oil chamber. Complex structure, manufacturing and maintenance is not convenient. We have designed a simple oil into the four-chamber hydrostatic bearings, see photo. The selection of its parameters and the general hydrostatic bearings exactly the same, the difference is that only four oil chamber into a pipe, the four throttle on the processing of the bearing body. Pressurized oil into the undercut from the inlet pipe, undercut groove processing in the outer circumference of the bearing body (which can also be machined in the bearing body into the housing hole on the inner circumference), respectively from the bearing body of the four restrictor Into the oil chamber. We have been worried about the throttle processing in the bearing body, after a long period of use, due to the flow of pressure oil friction, throttle orifice will
