类似空心支座这样的机械零件,在横载面重心周围有许多支撑筋,从而形成了一个坚固的整体构件。下面介绍几种确定这些支撑筋尺寸的方法。我们把这些支撑筋视为一根支撑筋来计算。环形空腔支撑筋尺寸计算公式为: r_r=D[1+(d/D)~2]/8式中r_r-环形空腔支撑筋直径; D-圆形外径; d-圆环内径。方形空腔支撑筋尺寸计算公式为: r_b=(H/6 2~(1/2))[1+(h/H)~2]式中r_b-方形空腔支撑筋断面边长; Mechanical parts, such as hollow bearings, have a number of struts around the center of gravity of the transverse plane, forming a solid, integral part. Here are some ways to determine the size of these tendons. We count these struts as a brace. The size of the annular cavity support rib is calculated as: r_r = D [1+ (d / D) ~ 2] / 8 where r_r - diameter of the annular cavity support ribs; D - circular outer diameter; d - annular inner diameter. The size of the square hollow support bar is calculated as follows: r_b = (H / 6 2 ~ (1/2)) [1+ (h / H) ~ 2] where r_b-
