减速箱总成如图1所示,其中齿轮平均寿命是国外同类产品的1/2～1/4,究其原因是由于齿轮副之间的相对位置变化太大所致。 从图2和图1上可以看出,影响两齿轮相对位置的参数为24.01mm±0.03mm,这一尺寸长期以来无法 Gearbox assembly shown in Figure 1, in which the average life expectancy of gears is 1/2 ~ 1/4 similar foreign products, the reason is due to the relative position between gear pairs change too much. As can be seen from Figure 2 and Figure 1, the parameters that affect the relative position of the two gears are 24.01 mm ± 0.03 mm, a dimension that has not been available for a long time
