Composite bearing within the cylindrical empty bearing installation method
2016-01-29
Cylindrical inner air bearing installation:
When the bearing ring and shaft or housing bore are a tight fit, apply a special mounting sleeve barrel while the bearing pressed into the shaft or bearing housing.
Separate bearing installation due to the inner and outer rings, respectively, can be easily mounted to the shaft or bearing housing. At this point should attract attention is to be already installed inner shaft has been installed the outer ring of the bearing box , try to keep it concentric to prevent abrasions rolling elements and raceways.
Tight fit of the bearing inner ring and the shaft, the outer ring bearing hole is relatively loose fit of the non-separation of bearings for installation, available in the press will be installed on the shaft bearing and the shaft together with the bearing mounted together to the bearing hole inside, if the bearing is small, it can also be a relatively soft metal hammer tap sets
When the bearing size is large, since the required installation force large or heavy duty work thus bearing a greater interference with the use of cold state problems during installation, you will need to pre-heat the bearing inner ring or housing after installation. When hot installation, the heating temperature should be strictly controlled. When heating bearings, the maximum heating temperature should not exceed 1200C, it should generally be in the 80 ~ 1000C. Bearings with shields or seals can not be heated, otherwise it will cause the loss of lubricant. Induction heating method can be beauty, oil bath heating method.
Composite bearing outer ring and the bearing hole tight fit, when the inner ring and the shaft is relatively loose fit, can be mounted on the bearing shaft.
The end face of the bearing ring to the force, but the striking force must be evenly distributed in the bearing rings.
