Plane 1 contact angle perpendicular to the bearing axis line (radial plane) and by the bearing ring or washer drive for the joint effect of rolling line (nominal angle between the line of action).
2 ball group (OD) bearing a ball inside (outside) with cylinder diameter.
3 roller group (external) diameter radial contact roller bearings within a column roller inner (outer) connected to the cylinder diameter.
4 nominal bearing ring width two theory end (the distance between the washer on the back). To define a radial bearing (thrust bearing width height).
The two tangent plane intersection distance between the axial lines of the 5 actual bearing width radial bearing and limit bearing ferrule end face of the width of the actual. The width of the bearing inner ring and outer ring end face of a face.
6 actual bearing width and nominal width deviation between actual bearing width.
Beat Kia inner ring at different angular positions when the 7 sets of radial bearing inner ring and outer ring, inner hole surface relative to the maximum and minimum radial distance between the fixed points of difference. In the angular position of the points or rolling body in the vicinity of the both sides and inner, outer ring raceway back edge (or inner ring of tapered roller bearings in the bearing parts contacting) that is opposite to normal.
Beat Kea outer ring at different angular positions when the 8 sets of radial bearing outer ring outside diameter surface relative to the inner ring, and the maximum and minimum radial distance between a fixed difference. In the angular position of the points on both sides at or in the vicinity of the rolling body shall be within the inner ring, outer ring raceway or the back wall (tapered roller bearing) is in contact bearing parts in position relative to normal.
9 sets of bearing inner ring end face of inner ring raceway beating Sia at different angular positions, at a distance from the inner ring axis radial distance is equal to the inner ring raceway contact diameter at half, inner ring reference between a fixed point with respect to the outer ring of the maximum and minimum axial distance difference. The inner, outer raceway shall all contact with the rolling body.
10 sets of bearing outer ring end face Sea beating raceway outer ring at different angular positions, at a distance from the outer axis of radial distance is 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, outer raceway shall all contact with the rolling body.
Beat Sd 11 end faces the holes in the radial distance from the axis of inner ring raceway contact diameter is equal to the half of the difference, maximum and minimum axial distance perpendicular to the ring axis plane and the reference face of ring.
