Do you know the spherical roller bearing installation and clearance?

spherical roller bearing installation:
The spherical roller bearing is equipped with a roller-shaped roller bearing between the inner ring having two raceways and the outer ring having a spherical race. The center of curvature of the raceway surface of the outer ring is identical to the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and outer casing are deflected, the axial load in both directions can be automatically adjusted. The radial load capacity is large, and it is suitable for heavy load and impact load. The inner ring inner diameter is a tapered bore bearing that can be mounted directly. Or use the adapter sleeve and the removal cylinder to mount on the cylindrical shaft. The cage uses a steel stamping cage, a polyamide forming cage and a copper alloy cage.

For spherical roller bearing installation, the intermediate mounting ring prevents the outer ring from tilting and rotating when the shafted bearing is inserted into the housing shaft hole. It should be remembered that some sizes of self-aligning ball bearings protrude from the side of the bearing, so the intermediate mounting ring should be recessed to prevent damage to the ball. A large number of bearings are generally installed by mechanical or hydraulic indentation.

For detachable spherical roller bearing installation, the inner and outer rings can be mounted separately, which simplifies the installation process, especially when the inner and outer rings require an interference fit. When loading a shaft with the inner ring in place into a bearing housing that already contains an outer ring, care must be taken to check that the inner and outer rings are properly centered to avoid scratching the bearing raceways and rolling parts. If the cylindrical and needle bearing are fitted with an inner ring without flange ribs or an inner ring with flanged sides on one side, it is recommended to use a mounting sleeve. The outer diameter of the sleeve shall be equal to the inner ring raceway diameter F, and the tolerance for machining shall be d10. Drawn cup needle roller bearings are preferably mounted using a mandrel.

Besides spherical roller bearing installation, maybe you want to know its clearance:
For the axial clearance of the spherical roller bearing, the adjusting nut on the journal, the adjusting washer and the thread in the bearing housing hole can be used, or the pre-tightening spring can be used to adjust. The size of the axial clearance is related to the arrangement of the bearing when it is installed, the distance between the bearings, and the material of the shaft and the bearing housing, which can be determined according to the working conditions. For high-load and high-speed spherical roller bearing installation, when adjusting the clearance, the influence of temperature rise on the axial clearance must be considered, and the amount of clearance caused by temperature rise is estimated, that is, axial travel.

The gap should be adjusted to a larger size. For spherical roller bearing installation with low speed and vibration, no clearance installation or preload installation is required. The purpose is to make the roller and the raceway of the spherical roller bearing have good contact, and the load is evenly distributed to prevent the roller and the raceway from being damaged by the vibration shock. After adjustment, the size of the axial clearance is checked with a dial gauge. The method is to first fix the dial gauge to the fuselage or the bearing seat, so that the dial gauge contact bears against the smooth surface of the shaft, and pushes the shaft along the axial direction, and the maximum swing amount of the hands is the axial clearance value.
