检验外齿轮方圆摆差时,齿轮套在心轴上,并加在顶尖间,其次将一定直径的滚柱依次放在各齿槽间,用千分表在垂直位置于滚柱顶面上进行测量,如图1所示。这样,齿轮转动一周后,千分表读数的最大和最小之差别即为齿轮节圆摆差。 但是;在检验内齿轮节圆摆差时,这个方法具体实行起来便不 Test gear outside the radius of the swing, the gear sets in the mandrel, and add between the top, followed by a certain diameter of the rollers in turn on the alveolar, with a dial gauge in the vertical position on the roller to measure the top surface ,As shown in Figure 1. In this way, the gear after a week of rotation, the maximum and minimum dial indicator reading difference is the gear pitch difference. However, when testing the pitch circle of the internal gear, this method is not implemented in practice
