1·In the dimensional plans, several outside diameters and width dimensions are assigned to each bearing bore diameter (Figures 1.761.78 and Table 1.9).

在尺寸方案，几个外径和宽度尺寸被标示为每个轴承孔直径(数字1.761.78和表1.9)。

2·When grinding the bearing ring, the outside diameter of it was taken as locating datum to process the outer raceway with the assistance of electromagnetic centerless clamper.

轴承环磨削过程中，以轴承环外径作为定位基准，在电磁无心夹具上磨削轴承环外滚道。

3·The shaft is fixed to the wheel body and arranged uniformly on the tooth path, and the outside diameter of the bearing or the shaft sleeve jacketed on the shaft is as wide as the tooth path.

所述轴固联于轮体，等分排列于齿道上，套于轴的轴承或轴套的外径与齿道等 宽。
