Spherical roller bearings in two raceway inner ring and raceway for the spherical outer ring, equipped with drum-shaped roller bearings. Outer ring raceway surface of the center of curvature and bearing the same, so with self-aligning ball bearings with the same self-aligning function. In the shaft, shell deflection occurs, you can automatically adjust the load and the axial load in both directions. Radial load capacity, suitable for heavy load, shock load situation. The inner diameter of the inner ring is a tapered bore bearing that can be mounted directly. Or use an adapter sleeve that is mounted on the cylinder shaft. Cage use of steel stamping cage, polyamide forming cage and copper alloy car cage.
For self-aligning bearings, the use of an intermediate mounting ring prevents tilting and rotation of the outer ring when mounting the shaft bearing into the housing shaft bore. It should be remembered that balls of self-aligning ball bearings of some dimensions protrude from the sides of the bearing, so that the intermediate mounting ring should be recessed to prevent damage to the balls. A large number of bearings are generally used mechanical or hydraulic pressure into the installation method.
For separable bearings, the inner ring and outer ring can be installed separately, thus simplifying the installation process, especially when the inner and outer rings are required when the interference fit, especially. In the inner ring has been installed in place of the shaft into the bearing housing has been included in the outer ring, you must pay attention to check whether the inner and outer ring alignment to avoid scratching the bearing raceway and rolling components. If cylindrical and needle roller bearings are provided with inner rings without flanged ribs or inner rings with flanged edges on one side, a mounting sleeve is recommended. The outer diameter of the sleeve shall be equal to the diameter of the inner ring raceway F, and the tolerance for machining shall be d10. Drawn cup needle roller bearings are best installed using the mandrel. |
