The installation of separable bearings is that the inner ring and the outer ring can be easily installed on the shaft or the bearing seat separately. At this time, it should be noted that the shaft with the inner ring is inserted into the bearing box with the outer ring. , Try to keep it concentric to avoid scratching the rolling elements and raceways. When installing a non-separable bearing with a tight fit between the inner ring and the shaft and the outer ring housing hole is a loose fit, the installation of the separable bearing is easy to install on the shaft or the housing because the inner ring and the outer ring can be installed separately At this time, it should be noted that when inserting the shaft with the inner ring into the bearing box with the outer ring, try to keep it concentric to prevent scratches on the rolling elements and raceways. When installing a non-separable bearing with a tight fit between the inner ring and the shaft of an imported bearing, and the outer ring housing hole is a loose fit, the bearing can be installed on the shaft with a press, and then the shaft and the bearing can be installed in the bearing seat. In the hole, if the bearing is small, a softer metal hammer can also be used to lightly hit the end face of the ring to force the bearing to work, but the striking force must be evenly distributed on the bearing ring.　　 When the outer ring of the bearing has a tight fit with the housing hole, and the inner ring has a loose fit with the shaft, the bearing can be installed on the shaft first. When the bearing ring is in a tight fit with the shaft or bearing seat hole, a special mounting sleeve barrel is used to press the bearing onto the shaft or bearing seat at the same time. 　 　 When the bearing size is large, due to the larger installation force, Or when the bearing under heavy load has a large fit and it is difficult to install it in a cold state, it is necessary to preheat the inner ring of the bearing or the bearing seat before installation. When installing in a hot state, the heating temperature should be strictly controlled. When heating the bearing, the maximum heating temperature should not exceed 1200C, generally 80~1000C. Bearings with dust caps or seals should not be heated, otherwise the lubricant will be lost. The heating method can be electric induction beauty, oil bath heating and other methods.
