将传统的内部节流形式进行改进,最大限度地减小节流腔的面积,用于静压向心轴承时避免了外部节流器容易堵塞的缺点,同时增加了工作油腔的有效面积,从而提高静压支承的承载能力和刚度。计算了采用该节流形式的静压向心轴承在不同节流比下的无量纲承载力和无量纲静刚度,并与相同工况下毛细管节流和小孔节流静压支承特性系数进行了比较。
The traditional form of internal throttle to be improved to minimize the area of the throttle chamber for static pressure radial bearings to avoid the shortcomings of the external throttle easily blocked at the same time increase the effective area of the working oil chamber, Thus increasing the hydrostatic bearing capacity and stiffness. The dimensionless bearing capacity and the dimensionless static stiffness of the hydrostatic radial bearing with throttle mode at different throttle ratios were calculated and compared with those under the same operating conditions A
