Double Row Angular Contact Ball Bearing
Double row angular contact ball bearing
Double row angular contact ball bearing can bear a large radial load mainly radial and axial combined load and moment load, to limit the axial displacement of the two sides of the shaft. Mainly used to limit the shaft and shell two-way axial displacement of the components in the double row angular contact ball bearing between the inner and outer ring can be tilted limited, allow the tilt angle depends on the internal clearance of the bearing, bearing size, internal design and the role of the force and moment on the bearing, and the maximum allowable tilt angle should ensure that the bearing does not produce too high additional stress. If there is a tilting angle between the inner and outer ring of the bearing, it will affect the life of the bearing, and at the same time cause the bearing running accuracy to decrease and the running noise to increase.
Double row angular contact ball bearing
Double row angular contact ball bearings generally use a nylon keep frame or brass solid keep frame. Double angular contact ball bearing installation should be noted, although the bearing can bear two-way axial load, if one side has a ball loading gap, it should be noted not to let the main axial load through the side of the gap groove edge. In the use of bearings should be careful not to load the ball notch on the side of the raceway to bear the main load.
Mounting forms
Angular contact ball bearing fast and easy automatic selection book can provide selection, angular contact ball bearing mounting forms, there are back-to-back, face-to-face and tandem arrangement of three. Back-to-back (two bearings of the wide end face relative) installation, bearing contact angle line along the direction of the rotary axis diffusion, can increase its radial and axial support angle rigidity, resistance to deformation capacity of the largest; face to face (two bearings of the narrow end face relative) installation, bearing contact angle line towards the rotary axis direction convergence, its support angle rigidity is smaller.
As the inner ring of the bearing extends out of the outer ring, when the outer ring of the two bearings are pressed together, the original clearance of the outer ring is eliminated, which can increase the preload of the bearing; Tandem arrangement (the wide end face of the two bearings in one direction) when installed, the contact angle line of the bearing in the same direction and parallel, can make the two bearings share the same direction of the working load. However, when using this mounting form, in order to ensure the axial stability of the installation, two pairs of bearings in a tandem arrangement must be installed at the opposite ends of the shaft.
