Structural classification of spherical roller bearings
The center of curvature of the raceway of the outer race is consistent with the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the axle and shell are bent, the axial load in two directions can be automatically adjusted. Radial load capacity, suitable for heavy load and impact load. Inner diameter is tapered bore bearings can be installed directly. Or the use of tight sets, the demolition cylinder installed on the cylindrical shaft. The cage uses a steel plate holder, a polyamide forming cage and a copper alloy car holder. For self-aligning bearings, the use of an intermediate mounting ring prevents the outer ring from tilting and rotating when the axle bearing is loaded into the shaft bore of the housing. It should be borne in mind that some of the self-aligning ball bearings protrude from the side of the bearing, so the middle ring should be recessed to prevent damage to the ball. A large number of bearings are generally installed by mechanical or hydraulic pressing.
Mainly applicable cage: stamping steel reinforced cage (suffix E, very few in China). Stamped steel cage (suffix CC), glass fiber reinforced polyamide 66 holder (suffix TVPB), machined brass two piece holder (suffix MB). Machined brass monolithic cage (suffix CA), vibrating case, steel plate holder (suffix JPA). Brass holder in vibration case (suffix EMA). There are different codes on the bearings of the same structure. Main uses: paper machine, speed reducer, railway vehicle axle, rolling mill gear box bearing, roller mill, crusher, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reducer and vertical self-aligning bearing seat. Spherical roller bearings have two raceways in the inner and outer ring raceways between spherical assembly, a drum shaped roller bearings.
