一、静压轴承的基本原理及其两种节流形式:图中所示为我厂二成品车间SASL315×400特大无心磨床改装后之静压轴承原理示意图。其中采用的节流器是薄膜反馈式。为了便于说明问题,我们仅举位于主轴上下的一对油腔和相应的薄膜反馈节流器为例,即:当主轴没有受到径向载荷W作用时,进入各油腔的压力油把主轴悬浮在轴承的中心,这时各油腔的间隙及油腔压力相同,便保持着平直状态。从图中可看出:当薄膜处 First, the basic principle of hydrostatic bearings and two forms of throttling: The figure shows the two plants I finished two workshops SASL315 × 400 eccentric centerless grinder modified hydrostatic bearings schematic diagram. Which uses the throttle is a thin film feedback. In order to illustrate the problem, we only take the case of a pair of oil chamber located above and below the spindle and the corresponding film feedback throttle, for example: when the spindle is not subjected to radial load W, pressure oil into the oil chamber to the spindle At the center of the bearing, the gap between the oil chambers and the oil chamber pressure are the same at this moment, and the flat state is maintained. Can be seen from the figure: When the film Department
