The bearing will encounter many technical terms in the installation process, Dongguan city double Bearing Co., summed up the following terminology commonly used and the corresponding analytical terms, please refer to, if there is a mistake to welcome!
The contact angle of 1 plane perpendicular to the bearing axis line (radial plane) and by the bearing ring or washer transmission to the joint effect of rolling line (nominal line) between the two.
The diameter of the inner (outer) cylinder of a ball in the inside diameter of the 2 ball group.
The diameter of the inner (outer) cylinder of a roller in the radial contact roller bearing of the 3 roller group.
4 nominal bearing ring width two end theory (the distance between the back of the washer). To define the width of the radial bearing (thrust bearing height).
Two tangent plane intersection and the distance between the center line of 5 actual bearing width and limit bearing radial bearing width of the actual end of the ring. Bearing width is defined by inner ring face and outer ring end face.
6 bearing actual width deviation bearing actual width and nominal width difference.
7 the radial runout of the inner ring of the inner ring of a complete set of bearings is the difference between the maximum and minimum radial distance between the inner surface of the inner ring and the fixed point of the outer ring at different angular positions. The angular position of the point above or on the two sides of the rolling body should be in contact with the inner or outer raceway or the inner side of the back side of the ball (tapered roller bearing) in contact with the inner surface of the bearing parts in a normal position.
8 sets of bearing outer ring radial runout Kea outer ring in different angular position, the outer diameter of the surface and the inner ring of a fixed between the maximum and minimum radial distance difference. The angular position of the above points or the rolling bodies on both sides of the point should be in contact with the inner or outer ring raceway or the back side of the inner ring (tapered roller bearing).
9 sets of bearing inner ring end face inner ring raceway beating Sia in different angular positions, from the inner ring axis radial distance is equal to the diameter of the inner ring raceway contact half, inner ring with respect to the reference face between the outer ring of a fixed point of maximum and minimum axial distance difference. The inner and outer raceways shall be in contact with all rolling elements.
10 sets of bearing outer ring raceway outer ring end face runout at different angular positions, from the outer axis of radial distance equal to the diameter of outer ring raceway contact at half, and between the inner ring base end relative to a fixed point of maximum and minimum axial distance difference. The inner and outer raceways shall be in contact with all rolling elements.
The 11 end of the bearing hole to beat Sd in the radial distance of inner ring axis is equal to the diameter of the raceway contact half, difference of maximum and minimum axial distance perpendicular to the ring axis plane and the reference face of a ring.
