节流器直接影响静压及动静压轴承的性能,采用内部节流的轴承相比外部节流不易堵塞,且具有反馈能力,但节流器要占据相当大的面积,造成轴承尺寸增大。为减小传统节流腔的面积,将节流腔改为圆台柱销形式,结构简单,不额外增加轴承尺寸,通过有限元计算得到了该节流方式下动静压径向轴承的静、动态特性系数。 Throttles directly affect the static pressure and dynamic and static pressure bearing performance, the use of internal throttle compared to the external throttle is not easy to plug, and has the ability to feedback, but the throttle to occupy a considerable area, resulting in increased bearing size. In order to reduce the area of ​​the traditional throttle chamber, the throttle chamber is replaced by the truncated cone pin. The structure is simple and the bearing size is not increased. The static and dynamic dynamic and dynamic pressure radial bearings under the throttling mode are obtained through the finite element method Characteristic coefficient.
