| Spherical roller bearings have double row rollers, the outer ring has a shared spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This ingenious structure makes it have self-aligning performance, so it is not easily affected by the angle between the shaft and the bearing box seat on the error or the shaft bending, and is suitable for the occasions where the installation error or the shaft deflection causes the angle error. In addition to bearing radial load, the bearing can also bear axial load acting in both directions. 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 an angle to the bearing axis, which has good self-aligning performance. The bearing can still be used normally, and the centering performance varies with the bearing size series. Generally, the allowable centering angle is 1~2.5 degrees. The load capacity of this type of bearing is large, and the bearing can withstand radial load in addition to radial load The axial load acting in both directions has good impact resistance. Generally speaking, the allowable working speed of spherical roller bearings is low. Types and characteristics of self-aligning roller bearings: The inner ring of type C bearing has no baffle on both sides, two cages, and a movable middle baffle ring between two rows of spherical rollers. When the bearing is running, the middle retaining ring can move AXIally to play a compensating role. When the bearing bears axial load, the load of the two rows of rollers can be adjusted so that the load is uniform and the stress concentration and the force of the single row of rollers can be avoided. CA bearing inner ring on both sides of the baffle, there is a cage, two rows of spherical roller between (or not) a movable baffle ring, bearing running, the middle baffle ring can be axial movement, play a role in compensation, when bearing under axial load can adjust the load of two rows of roller, so that the uniform load, avoid stress concentration. If there is no active baffle, its function is borne by the cage. The inner ring of a self-aligning roller bearing with a fixed guard has a guard on both sides, a fixed middle guard in the middle, and two cages. Although the roller and C, CA bearing roller are spherical roller, the length of the roller is not symmetric in the axial direction. When the bearing is running, the middle retaining ring can not move axially, but it guides the roller well. When the bearing bears axial load, it can not adjust the load of the two rows of rollers, and it is easy to force the single row of rollers or produce stress concentration. Although the structure has the tendency to be replaced by C and CA bearing, it still has certain advantages in some applications, such as the occasions where the axial load is not large and the vibration load is large.Roller Bearing manufacturers website:http://www.sdzrbearing.com/bearing/roller-bearing/ |
