1、滑动轴承装配
1. Sliding bearing assembly
同一传动中上轴承中应在一条直线上，即保持其同轴度。轴承座接触须紧密、牢靠地固定在机体。机械运转时，轴承座不可以与机体发生相对位移。轴瓦合缝处位置的垫片不应与轴接触，离轴瓦内径边缘一般不宜大于1mm。
In the same transmission, the upper bearing should be in a straight line, that is, keep its coaxiality. The contact of bearing seat shall be tightly and firmly fixed on the machine body. When the machine is running, the bearing seat can not move relative to the body. The gasket at the joint of the bearing bush shall not contact with the shaft, and the distance from the edge of the inner diameter of the bearing bush shall not be more than 1 mm.
2、滚动轴承装配
2. Rolling bearing assembly
滚动轴承安装在对开式轴承座内时，轴承盖和轴承座的接合面间应无空隙，但轴承外圈两侧的瓦口处应留出一些间隙。凡稀油润滑的轴承，不准加润滑脂。滚动轴承允许采用机油加热进行热装，油的温度不可以高于100摄氏度。
When the rolling bearing is installed in the split type bearing seat, there should be no gap between the joint surface of the bearing cover and the bearing seat, but some gap should be left at the Bush mouth on both sides of the bearing outer ring. Grease is not allowed for bearings lubricated with thin oil. Rolling bearings are allowed to use oil heating for hot charging, and the oil temperature can not be higher than 100 ℃.

3、联轴器装配
3. Coupling assembly
不同联轴器的装配，应符合有关联轴器标准的规定。
The assembly of different couplings shall comply with the provisions of relevant coupling standards.
4、传动皮带、链条和齿轮装配
4. Assembly of drive belt, chain and gear
每对皮带轮或链条装配时两轴的平行度偏差不应大于0.5/1000；两轮的轮宽度的中平面应在同一平面上（指两轴平行），其偏移量：三角皮带轮或链轮不大于1mm，平皮带不应大于15mm。
During the assembly of each pair of belt pulley or chain, the parallelism deviation of two shafts shall not be greater than 0.5g1000; the middle plane of the width of two wheels shall be on the same plane (it means that the two shafts are parallel), and its offset: the triangle belt pulley or sprocket shall not be greater than 1mm, and the flat belt shall not be greater than 15mm.
