Different bearing layout is introduced

SKF bearing type has a lot of, different ways of SKF bearing type has a different layout, China bearing network according to detailed understanding of SKF bearing knowledge, what are the following main share some bearing layout, hope to be of help. A, positioning/non bearing only by interference fit for axial positioning of bearing ring is not enough. Usually, the need to adopt some appropriate methods for axial positioning of bearing ring. Positioning bearing inner and outer ring should be on both sides of the axial fixation. Integral structure for the positioning of bearings, angular contact ball bearing, for example, a bearing ring with tighter ( Usually the inner ring, , it is necessary to axial fixation; Another bearing ring is relative to the mounting surface to the earth's axis to move freely. The separable structure of locating bearing, cylindrical roller bearing, for example, inside and outside the ring needs to be fixed axial. Working in the machine tool applications, the end bearing is usually transmitted from shaft to the bearing axial load to locate the spindle. Therefore, usually work end bearing axial positioning, while the drive end bearing can be axial free to move. Second, adjust the bearing arrangement such as: the centripetal bearing generally has three different arrangement: back-to-back arrangement ( The wide-brimmed relative) ； Type arrangement (face to face The narrow edge relative) ； Synthetic array layout ( The joint) 。 They can be close together in pairs, also can use gaskets or sleeve is separated, some design layout according to the requirement of the spindle bearing arrangement of three or more together. High-speed spindle, Such as the circular grinding tool) Most used single bearing, and compression spring is commonly used to eliminate the clearance between the ball and bearing inner and outer ring. Back-to-back arrangement in this way after installation, bearing of the ball bearing with inner and outer contact wires, namely, the line of contact Angle along the rotation axis direction diffusion, thus increase the radial and axial rigidity, resistance to deformation ability is the largest. Face-to-face type decorates installation in this way, the points of contact ball bearings with inner and outer ring of attachment, namely the convergence line of contact Angle along the rotation axis direction, bearing inner ring out of outer ring at the same time, when the two bearing outer ring clamp together, began to eliminate the original clearance between the outer ring. Synthetic array layout to choose this way to install bearing, two have additive load centripetal ball bearings can share the work load. This layout makes parallel to and with the bearing contact Angle, but in order to ensure the installation of axial stability, must be in both sides respectively to put two same bearing. Three, cross fixed
