Why are more and more people choosing spherical roller bearings?

Spherical roller bearings are suitable for angular errors caused by installation errors or shaft deflections. In addition to bearing radial loads, the bearing can also accommodate axial loads acting in both directions.

What types of spherical roller bearings are there?

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 of main motor, newly designed symmetrical spherical roller of main motor Bearing bearings are currently rarely used The internal structure has been extensively improved, Designed and optimized Compared with the spherical roller bearings of early production, it can withstand greater axial loads The operating temperature of this bearing is lower, therefore it is lower can meet the requirements of higher speed. Depending on whether the inner ring has ribs or not and the cage is used, it can be divided into spherical roller bearings type C and CA. The type C bearing is not characterized by an inner ring The ribs and the steel stamping cage are adopted, and the characteristics of the CA bearings are that on both sides there are ribs s of the inner ring and a solid car cage.

What concrete measures are there to improve the black skin of the raceway edge of the outer ring of spherical roller bearings?

Concrete measures to improve the black skin of the outer ring raceway edge of spherical roller bearings:

(1) Strictly control the width dimension deviation of the ferrule during turning to create conditions for turning the raceway;

(2) Strictly control the position error of the raceway during turning;

(3) Reduce the radius of curvature of the raceway of the outer ring appropriately during turning to suppress the heat treatment deformation;

(4) Reduce the grinding addition when turning raceway to improve grinding efficiency. It is apparent that most of the one-sided black skin of the outer ring raceway of the spherical roller bearing is caused by excessive groove position deviation or excessive height deviation during rotation, while the double-sided black skin of the raceway is mainly caused by heat treatment deformation.

Why are more and more people choosing spherical roller bearings?

1. The radial load bearing capacity of spherical roller bearing is large. Easy to install, it can be installed directly or installed with a clamping sleeve and mounting cylinder on the cylindrical shaft.

2. The spherical roller bearing can withstand a certain axial load. The raceway of the outer ring of this bearing type is spherical and can withstand large radial loads. Therefore, it has a self-aligning performance and is not affected by the misalignment of the shaft and B. the bearing housing or the deformation and deflection of the shaft, and can compensate for the coaxially error.

3. Spherical roller bearings have two rows of spherical rollers, the outer ring has a common concave ball raceway, the inner ring has two concave raceways inclined at an angle to the bearing axis, and the curvature center of the outer ring raceway is the same as that of the bearing.

4. In addition to bearing radial load, the spherical roller bearing can also bear bidirectional axial load and its combined load. The load-bearing capacity is large and it has good anti-vibration and impact resistance.
