磨削齿轮内孔是通过自动装置依次将齿轮装在有滚柱体的夹圈内,每次一只,然后在内圆磨床上由三只淬硬并磨削过的卡爪夹紧,如图所示。由于这种粗磨齿轮的偏差要求不高,就节圆而言其偏差不大于0.0044in。因此,我们决定一次磨削两只。只要加宽夹圈上的滚柱体(见图),通过夹紧滚柱体来夹紧其间的两只齿轮,并调节两只齿轮的齿宽。滚 Grinding the gear bore through the automatic device followed by the gear mounted in the cylinder with a clamping ring, one at a time, and then on the internal grinder from the three hardened and ground jaw clamped, such as Figure shows. As a result of this coarse grinding gear deviation is not high, the festival round in terms of its deviation is not greater than 0.0044in. Therefore, we decided to grind two at a time. Just widen the rollers on the clamping ring (see picture) and clamp the two gears in between by clamping the rollers and adjust the tooth width of the two gears. roll
