Spherical roller bearings have two rows of rollers, which mainly bear radial loads, but can also bear axial loads in any direction. It has high radial load capacity, especially suitable for working under heavy load or vibration load, but cannot bear pure axial load. The outer ring raceway of this type of bearing is spherical, so its alignment performance is good and it can compensate for the coaxiality error. There are two rows of symmetrical spherical rollers, the outer ring has a common spherical raceway, and the inner ring has two raceways inclined at the same angle to the axis of the bearing. It has good self-aligning performance. When the shaft is bent or installed out of center The bearing can still be used normally at the same time. The alignment varies with the bearing size series. Generally, the allowable alignment angle is 1~2.5 degrees. This type of bearing has a large load capacity, and the bearing can withstand radial load. The double-acting axial load has good impact resistance. Generally speaking, the allowable working speed of spherical roller bearings is low. Spherical roller bearings are divided into two different structures: symmetrical spherical rollers and asymmetrical spherical rollers according to the cross-sectional shape of the rollers. Asymmetrical spherical roller bearings are early products, mainly for maintenance services for the main engine, and the new design of the main engine Symmetrical spherical roller bearings are rarely used. The internal structure has undergone a comprehensive improvement design and parameter optimization. Compared with the earlier produced spherical roller bearings, it can withstand greater axial load. The operating temperature of this bearing It is lower, so it can meet the requirements of higher speed. According to the inner ring with or without ribs and the cage used, it can be divided into two types: C type and CA type. C type bearings are characterized by no inner ring ribs and steel plate Stamping cage, CA type Teruien bearings are characterized by ribs on both sides of the inner ring and the use of car-made solid cages. In order to improve the lubrication of the bearing, the outer ring can be provided with an annular oil groove and three oils. Hole spherical roller bearings are represented by the bearing post code /W33. According to user requirements, spherical roller bearings with inner ring oil holes can also be supplied. In order to facilitate customer installation and replacement of bearings, inner holes can also be provided The taper of the spherical roller bearing bearing, the taper of the taper hole is 1:12, and the post code is K. In order to meet the requirements of special users, the bearing with the inner hole taper of 1:30 can also be provided, and the post code is K30. Bearings with taper holes can be directly mounted on the tapered journal with a lock nut, or can be mounted on the cylindrical journal with the aid of an adapter sleeve or a withdrawal sleeve.
