Advantages and applications of self-aligning ball bearings in high temperature resistance

wallpapers Tech 2020-11-20
The self-aligning ball bearing is an indispensable basic part of mechanical equipment. Because of its good sealing function, long service life, and self-aligning function, it can be said that it occupies an important position in the bearing field. So what are the advantages and applications of self-aligning ball bearings in high-temperature resistance?
 
1. What is a self-aligning ball bearing?
 
A self-aligning ball bearing is a bearing with spherical balls installed between the inner ring and the outer ring of the spherical surface of the two raceways. The outer diameter of the self-aligning function bearing and the inner diameter of the bearing seat is spherical cooperation, and there is an active centering function between the two, which can compensate for the misalignment of the axis caused by the device error and the deformation of the device bottom surface.
 
2. The definition of self-aligning ball bearing
 
The center of curvature of the raceway surface of the outer ring of the self-aligning ball's high-temperature bearing is consistent with the bearing center, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and housing are bent, it can be adjusted automatically without increasing the bearing burden. The self-aligning ball's high-temperature bearing can bear radial load and axial load in the second direction.
 
Large radial load capacity, suitable for heavy load and shock load. Bearings whose inner diameter is a tapered bore can be directly installed. Or use an adapter sleeve or a disassembly tube to install it on the cylindrical shaft. The cage uses steel stamping cages and copper alloy car cages.
 
3. Advantages of self-aligning ball bearings
 
(1) When the shaft or housing is deflected, it can be adjusted automatically and has self-alignment without increasing the bearing burden.
(2) Self-aligning ball bearing has a large radial load capacity, which is suitable for heavy load and shock load.
(3) Good seismic performance and long service life.
(4) Better sealing function
(5) Concentricity errors caused by machining, installation and shaft deformation can be compensated.
 
4. Application places of self-aligning ball bearings
 
Self-aligning ball bearings are suitable for bearings that can cause considerable shaft deflection or misalignment, such as fine appearance, low noise motors, automobiles, motorcycles, woodworking machinery, textile machinery drive shafts, mining machinery, electromechanical Equipment, plastic machinery, work equipment, medical equipment, fitness and sports equipment and general machinery, etc.
