Second, the bearing parts: (a) bearing parts general 1. Bearing parts bearing part One of the components that make up the rolling bearing, but does not include all the accessories. 2. Bearing ring bearing ring A ring-shaped part of a radial rolling bearing with one or several raceways. 3. Bearing washer bearing washer A ring-shaped part of a thrust rolling bearing with one or several raceways. 4. Flat retaining ring loose rib A separable, substantially flat washer with its inner or outer part as a rib for the outer or inner ring of a radial cylindrical roller bearing. 5. Separate collar A collar that has a separable "L" section and uses its outer portion as a rib for the inner ring of a radial cylindrical roller bearing. 6. Neutral ring guide ring A detachable ring in a roller bearing with two or more rows of rollers for isolating the two rows of rollers and guiding the rollers. 7. Circating ring ring A single-port ring with a constant cross section, mounted in an annular groove, axially positioning the rolling bearing in the housing or on the shaft. 8. Locking ring retaining snap ring A single-port ring with a constant cross-section that fits in the annular groove as a retaining ring to hold the roller or cage in the bearing. 9. Spacer spacer is a ring-shaped part used between two bearing rings or bearing washers or between two half bearing rings or between two half bearing washers to maintain the specified axial distance between them. 10. Seal seal An annular cover consisting of one or several parts, fixed to a ferrule or washer of the bearing and in contact with another ferrule or gasket or forming a narrow labyrinth gap to prevent oil leakage and foreign matter intrusion. . 11. The dust cover is an annular cover, usually stamped from a thin metal plate, fixed to a ferrule or washer of the bearing and extended toward the other ring or washer to cover the inner space of the bearing, but not the other A set of rings or washers are in contact. 12. Guard ring A part attached to the inner ring or shaft ring that uses centrifugal force to enhance the ability of the rolling bearing to prevent foreign objects from entering. 13. Rolling element A ball or roller that rolls between the raceways. 14. The cage cage partially encloses all or some of the rolling elements and moves the bearing parts together to isolate the rolling elements and usually also guides the rolling elements and holds them in the bearings. (II) Structural features of the bearing parts 1. Raceway The rolling bearing bears the surface of the load part and serves as a rolling track for the rolling elements. 2. Straight raceway The straight raceway in the plane perpendicular to the rolling direction is a straight raceway. 3. crowned raceway A generally cylindrical or conical raceway with a continuous micro-convex curve in a plane perpendicular to the direction of rolling to prevent stress concentrations at the contact of the roller with the raceway. 4. Spherical raceway The spherical raceway is a part of the surface of the ball. 5. Channel raceway groove The ball bearing raceway is grooved, usually a circular cross section with a radius slightly larger than the radius of the ball. 6. (groove) shoulder (groove) side of the groove (rolling). 7. Flange The rib protrudes from the narrow shoulder of the raceway surface parallel to the rolling direction. It is used to support and guide the rolling elements and keep them in the bearing. 8. Guide the surface of the cage. cage riding land The cylindrical surface of the bearing ring and washer to guide the cage in the radial direction. 9. Ferrule face The ring (washer) face is perpendicular to the ferrule (washer) surface of the ferrule (washer) axis. 10. Bearing bore bearing bore The inner bore of a rolling bearing inner ring or shaft ring 11. Cylindrical bore The inner bore of a bearing or bearing part whose base wire is substantially straight and parallel to the bearing shaft or the bearing part axis . 12. tapered bore The internal bore of a bearing or bearing component whose busbar is substantially straight and intersects the bearing shaft or the bearing component axis. 13. Bearing outer surface bearing outer surface The outer surface of the outer ring or race of the rolling bearing.
