Slewing Bearings

It is a way to withstand the large axial load, radial load and overturning moment loads such as large-scale integrated bearings

Rolling

1. Ball ball rolling 2. Roller has its axis of symmetry and the vertical axis line Ren Yiping plane showed a circular cross-section rolling. 3. The ball (roller) bearing the whole within a particular all ball (roller). 4. The ball (roller) group within a rolling ball (roller). 5. Cylindrical Roller roller outer surface of the bus is basically a straight line and parallel with the roller axis line. 6. Needle length and diameter, the larger the ratio of small-diameter cylindrical roller, the general length of the diameter between 3 to 10 times, but the diameter of usually not more than 5mm. Needle head can have several shapes. 7. Tapered Roller roller outer surface of the bus is basically a straight line and intersecting with the roller axis line, usually cut cone. 8. (Convex) spherical roller roller convex outer surface in the plane containing its axis line to the convex arc. 9. Concave roller roller at the outer surface of the plane containing the axis line within the concave arc. 10. Symmetric spherical roller spherical roller outer convex surface of the roller through the middle of the plane perpendicular to their axis lines on both sides are symmetrical. 11. Non-symmetric convex spherical roller spherical roller through the roller outer surface of the central axis line perpendicular to their plane on both sides of a non-symmetrical. 12. Convexity essentially cylindrical roller or the outer surface of conical roller roller axis line that contains the plane, convex curve was continuous to prevent the roller in contact with the raceway end to produce stress concentration. 13. Dressing roller in the roller end of the outer surface, its diameter slightly amended in order to prevent the roller and raceway contact stress concentration end. 14. Spiral roller made of steel spiral section around the roller. 15. Roller face the basic axis perpendicular to the roller surface end of the line. 16. Roller or large end of tapered roller bulk of symmetric spherical roller end. 17. Roller small end of tapered roller or spherical roller symmetrical face a small head. 18. Chamfered roller roller end face connected with the outer surface of the surface.

 

 

Bearing washer

1. Axis mounted on the shaft bearing ring gasket. 2. Seat installed here within the bearing washers. 3. In both sides of the raceway ring bearing washers, Thrust bearing for double row rolling elements between the two. 4. Self-aligning ball seat with seat back to accommodate the axis line and a permanent seat axis angular displacement between the lines. 5. Aligning seat washers for aligning seat ring and the shell to withstand the thrust washers between the surface, the surface is concave spherical surface and aligning the ball on the back seat match.

 

Structural characteristics of bearing parts

1. Roller bearings under the load part of the surface, for rolling the rolling track. 2. Straight roller rolling in the direction perpendicular to the plane of the bus for the line roller. 3. Convexity roller rolling in the direction perpendicular to the plane convex curve was continuous basic cylindrical or conical roller to prevent the roller and raceway contact of stress concentration. 4. Spherical ball raceway raceway portion of the surface. 5. Channel ball bearing raceway groove shape, usually an arc-shaped cross section, slightly larger than the radius of its radius. 6. (Groove) groove shoulder (roll) side of road. 7. Rib prominence in the raceway surface and rolling direction parallel to the narrow shroud. To support and guide the rolling elements and keep it in the bearing. 8. Guide the cage surface of the cylindrical bearing rings and gasket surface to the radial guide cage. 9. Ring (gasket) face perpendicular to the ring (washer) axis line of the ring (gasket) surface. 10. Bearing bore or shaft bearing inner ring bore 11. Cylindrical bore bearing or bearing part of the inner hole, the bus was basically straight line or with the bearing axis parallel to the axis of bearing parts. 12. Conical bore bearing or bearing part of the inner hole, the bus was basically a straight line and with the bearing or bearing part axis line intersects the axis line. 13. Bearing outer surface of the bearing outer ring or the outer surface of seat. 14. Ring (gasket) chamfered bearing bore or the outer surface of one end connected with the ring ring (gasket) surface. 15. The more process slots in the bearing ring or bearing wall or flange gaskets to facilitate grinding the root of the open trench or slot. 16. Seal (contact) surfaces in contact with the seal sliding surface. 17. Seals (dust cover) slot to maintain the bearing seal (dust cover) of the slot. 18. Snap ring groove to maintain the snap ring groove. 19. Lubrication groove in the bearing part on the slot used for the transmission lubricant. 20. Lubrication hole in the bearing parts, and used to transport the lubricant holes on rolling.

 

 

Double row angular contact ball slewing bearing (slewing ring)

Double-row slewing bearing has three seat, steel balls and isolation blocks can be directly discharged into the upper and lower raceway, according to stress conditions, arranged from top to bottom two rows of steel balls of different diameters.
