When the bearing inner ring and the shaft are tightly cooperated, and the outer ring bearing housing hole is a loosely coupled non-detachable bearing device; the bearing can be first mounted on the shaft; then the shaft is mounted together with the bearing to the bearing housing hole Inside; if the bearing is small; you can also use a soft metal hammer to tap the end face of the ferrule to force the bearing to reach; but the tapping force must be evenly distributed on the bearing ring.
The bearing outer ring and the bearing housing hole are tightly cooperative, and the inner ring and the shaft are loosely coupled; the bearing can be first mounted on the shaft.
When the bearing ring is tightly engaged with the shaft or housing bore, a special device sleeve is used to press the bearing onto the shaft or housing.
The device for the separate bearing can be easily attached to the shaft or the bearing housing because the inner ring and the outer ring can be easily removed. At this point, it should be paid attention to the fact that the shaft that has been installed inside the inner ring is pierced into the bearing box with the outer ring installed; try to keep it concentric; to prevent scratching the rolling body and the raceway.
When the bearing scale is large; because the required device force is large; or the bearing cooperation with heavy load operation is too large, it is difficult to select the cold state device; then it is necessary to heat the bearing inner ring or the bearing seat beforehand. Carry out the device. In the hot state device; the heating temperature should be strictly controlled. When heating the bearing; the heating temperature should not exceed 1200C; usually it should be 80~1000C. The bearing with dust cover or sealing ring can not be heated; otherwise it will form lubricant Lost. Heating method can be selected by electric induction, oil bath heating and other methods.
