Analysis of SKF angular contact ball bearings combined with selected skills

SKF bearing angular contact ball bearings is the role of the geostationary ring and rotating ring with the stationary part of the mount (usually bearing) and rotating parts (usually the axis) with consolidation, enabling the rotation passed load and limited movement system relative to the stationary system the basic tasks of the position.
On shafts and in housings, requirements of angular contact ball bearings in radial, axial and tangential direction, three fixed its position. Radial and tangential orientation achieved through the tight fit of the bearing rings-production, axial location and only in a few cases with tight fit; General subject to axial components, such as cover and retaining ring, limit the axial position in the context of clearance.
When choosing a tie should focus on the following four points:
(1) the circumferential surface for SKF bearing rings should have good supporting force evenly and to reduce distortion and can give full play to the carrying capacity of the bearing.
(2) the rings cannot be sliding along the tangent at its surface, doing so could damage the mating surfaces.
(3) the free end of SKF bearings must be commensurate with the length of the shaft and housing bore change, that is, must have the capacity to adapt to swim axial position within a certain range.
(4) care must be taken to enable SKF bearing installation and removal easy, saving time and labor costs.
SKF bearing dimensional accuracy and precision of rotation is according to ISO and JIS Standards. For machinery requiring high precision and high speed, grade 5 or above is recommended-precision angular contact ball bearings, rigid, when bearing rolling element and the Raceway contact surface pressure on elastic deformation. Some mechanical elastic deformation needs to be kept to a minimum. Roller bearings are smaller than the elastic deformation of the ball bearings.
