Bearing in the installation process will encounter many technical terms, duplex bearing Co., Ltd., Dongguan City, summed up the following terminology commonly used and the corresponding term analysis, welcomed the reference, if there is an error please give correct!
1. Contact angle vertical to axis line plane (radial) and after the bearing ring or washer drive to rolling body force between the line of action (nominal role of line) angle.
The diameter of the inner (outer) of the inner (outer) of a ball in the ball bearing inner (outside) of the 2 ball group.
Inner (outer) diameter of the inner (outer) diameter of the inner (outer) of a row of rollers in the 3 roller group.
4 nominal bearing ring width two end theory (the distance between the back of the washer). To limit the width of the radial bearing (thrust bearing height).
5. The actual bearing width centripetal bearing axis line with limited width of bearing ferrule actual end two tangential intersection plane distance. Defining bearing width with the end face of the inner ring and the end face of the outer ring.
6 the actual width of the actual bearing width deviation of the actual width of the bearing and the difference between the nominal width.
7 the difference between the maximum and minimum radial distance between the inner hole surface and the fixed point on the inner hole surface and the fixed point of the inner ring of the bearing ring in different angular positions of the inner ring of the bearing ring Kia. At the corners of the above points or in the vicinity of the rolling elements on both sides of the inner and outer ring or inner ring back edge of the block (tapered roller bearing) in contact with the bearing parts in normal relative position.
8 the difference between the maximum and minimum radial distance between the outer diameter surface and the relative inner ring at different angular positions of sets of bearing rings. At the angle of the above points or in the near both sides of the rolling elements should be in the inner, outer ring or inner ring back edge of the block (tapered roller bearing) in contact with the bearing parts in normal relative position.
9. The complete bearing inner ring end face of the raceway beating SIA inner ring at different angular positions, in from the inner ring axis radial distance is equal to the inner ring raceway contact diameter half, inner ring base end with respect to the outer ring of a fixed point between maximum and minimum axial distance difference. Inside and outside the roller should be in contact with all the rolling body.
. the complete bearing outer ring end face of the raceway beating outer ring at different angular positions, in from the outer axis of radial distance is equal to the outer ring raceway contact diameter half, ring base end with respect to inner ring of a fixed point difference between the maximum and minimum axial distance. Inside and outside the roller should be in contact with all the rolling body.
11. The end of inner hole of the bearing beating SD in the distance the radial distance from the axis of the inner ring is equal to the rolling contact diameter half of the vertical axis line of the ring and the plane of the ring base end between the maximum and minimum axial distance.
