Roller and cage assemblies for radial (thrust) roller bearings. When required; roller types can be added to this section; for example "needle and cage thrust assemblies" or "cylindrical rollers and cages centripetal Component".
four. Scale (a) scale plan and series 1. Scale plan
A system or table containing the dimensions of a rolling bearing.
2. Bearing series bearing series
A specific set of rolling bearings; with progressively added dimensions; in most cases there is the same contact angle and there is a certain relationship between the physical dimensions.
3. Scale series dimension series
Width series or combination of height series and diameter series; tapered roller bearings also contain viewpoints.
4. Diameter series diameter series
Part of the current normative scale plan in China; the series of bearing outer diameters; for each gauge bearing inner diameter; there is a series of outer diameters; and there is often a specific relationship between the two diameters.
5. Width series width series
Part of the current normative scale plan in China. The series of bearing widths; the inner diameter of the bearing for each diameter series;
6. Height series
China's current standard thrust bearing scale plan part of the bearing height of the series; bearing diameter for each diameter series; there is a series of heights.
7. View series series angle series
China's current specification of tapered roller bearings is part of the scale plan. A specific size of the contact angle.
(2) Axis line, plane, direction 1. Bearing axis
The theoretical axis of rotation of the rolling bearing; the radial bearing, ie the inner ring axis; the thrust bearing, the shaft axis.
2. Inner ring (shaft) inner ring (shaft washer) axis
The inner cylinder of the inner ring (shaft ring) or the inner cylinder of the conical hole or the axis of the inscribed cone.
3. Outer ring (housing washer) axis If the outer ring of the outer ring is cylindrical; then the outer core of the external cylindrical axis is the outer ring axis; if it is the outer It is spherical; it passes through the outer surface of the outer ring of the outer ring; the line straight to the reference end face of the outer ring; the axis of the outer ring.
4. Conical inner ring (outer ring) axis line cone (cup) axis
The axial line of the inner ring (outer ring) of tapered roller bearings.
5. Radial plane
A plane that is straight to the axis of the axis; a plane parallel to the reference plane of the ferrule or the tangential surface of the back of the gasket; can be considered as a radial plane.
6. Radial radial direction
The direction of the axis through the axis in the radial plane.
7. Axial plane
The plane that accommodates the axis of the shaft.
8. Axial axial direction
Parallel to the direction of the bearing axis, straight to the ferrule reference end or the back of the washer; can be considered axial.
9. Radial (axial) distance
