一、静压轴颈轴承设计多孔质静压气体轴颈轴承结构尺寸示意图如图10所示,同静压滑动止推轴承一样,假定忽略多孔质材料的内部阻抗,并假定只有内孔进行过阻塞处理,因此具有节流作用。轴承各部分尺寸标于图上并假设轴承有效长度2L,直径D=2R,轴承半径方向间隙C_r,轴的偏心率ε。图11(a)、(b)中给出了长径比L/R=1的气体轴承在供气压力比p_s/p_a=4,10两种不同值时的承载能力曲线,图的横轴为供气系数的二分之一(r_3/2),纵轴为无量纲载荷能力 First, hydrostatic journal bearing design Porous hydrostatic porous bearing geometry diagram shown in Figure 10, the same with the static pressure sliding thrust bearing, assuming that the internal impedance of porous material is ignored, and assume that only the bore was blocked Therefore, it has a throttling effect. Bearing the size of each part marked on the map and the assumption that the effective bearing length 2L, diameter D = 2R, bearing radial clearance C_r, shaft eccentricity ε. Fig. 11 (a) and (b) show the bearing capacity curves of gas bearings with aspect ratio L / R = 1 at two different values ​​of supply pressure ratio p_s / p_a = 4 and 10, Is one-half of the air supply coefficient (r_3 / 2) and the vertical axis is dimensionless load capacity
