Use and installation of aligning roller bearings



Main applicable cage: stamping steel plate reinforced cage (suffix E, few domestic).Stamping steel plate retainer (suffix CC), glass fiber reinforced polyamide 66 retainer (suffix TVPB), machined brass two-piece retainer (suffix MB).Machined brass integral cage (suffix CA), stamped steel plate cage (suffix JPA) for vibration occasions.Vibration case brass cage (suffix EMA).Bearing codes may be different for the same structure.

Main applications: papermaking machinery, reduction gear, railway vehicle axle, rolling mill gear box bearing, rolling mill roller, crusher, vibrating screen, printing machinery, woodworking machinery, various industrial reducer, vertical centering bearing with seat.[2]

The installation

The aligning roller bearing is equipped with a drum roller bearing between the inner ring with two raceways and the outer ring with a spherical raceway.The curvature center of the outer ring raceway surface is consistent with the bearing center, so it has the same centering function as the automatic centering ball bearing.In the case of deflection of the shaft and shell, it can automatically adjust the load and the axial load in two directions.Radial load capacity, suitable for heavy load, impact load.Inner ring inner diameter is taper hole bearing, can be installed directly.Or use the fixed sleeve, remove the cylinder installed on the cylindrical shaft.The cage USES steel plate stamping cage, polyamide forming cage and copper alloy car cage.

For self-aligning bearings, an intermediate mounting ring is used to prevent the outer ring from tilting and rotating when the bearing with the shaft is loaded into the box shaft hole.It should be remembered that the ball bearings of some sizes of self-aligning ball bearings protrude from the side of the bearing, so the middle mounting ring should be recessed to prevent damage to the ball bearings.A large number of bearings are generally installed by mechanical or hydraulic pressure method.[3]

For detachable bearings, the inner ring and outer ring can be installed separately, which simplifies the installation process, especially when both inner and outer rings need interference fit.When loading the shaft with inner ring in place into the bearing box with outer ring, attention must be paid to check whether the inner and outer rings are correctly aligned to avoid scratching the bearing raceway and rolling parts.If cylindrical and needle roller bearings use an inner ring with no flange retaining edge or an inner ring with a flange edge on one side, it is recommended to use the mounting sleeve.The outer diameter of the sleeve shall be equal to the inner raceway diameter F, and the tolerance standard for machining shall be d10.The needle roller bearing of the stamping outer ring is preferably installed with a spindle.
