转臂行星轮孔的公差,主要是指其中心和太阳轮中心之距离的公差和二行星轮孔中心间所夹中心角的公差(或换算为斜长公差)。这两项公差至今没有统一的标准,其公差确定及标注方法存在问题,对此谈谈我们的看法。 The tolerances of the orbiting planet gear hole mainly refer to the tolerance of the distance between its center and the center of the sun gear and the tolerance of the center angle between the centers of the two planet gears (or is converted into oblique tolerances). There is no uniform standard for these two tolerances so far, and there are problems with the methods for determining and labeling tolerances. Let’s talk about our views.
