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

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.

Bearing parts

Bearing parts Zonglun

1. Composed of rolling bearing parts of the various components, but does not include all of the attachments. 2. Bearing ring with one or more roller bearings to the heart of the circular parts. 3. Bearing washers with one or more thrust roller bearing ring parts. 4. Flat ring is basically a detachable flat washer, with its inner or outer part of the heart as a cylindrical roller bearings to the outer or inner ring of a wall. 5. Oblique collar (detachable) with a detachable "L" shaped cross-section of the ring, with its external part as cylindrical roller bearings to the inner heart of a wall. 6. In the ring with two or more columns in the roller of a roller bearing detachable circle, used to isolate the two rollers and guide rollers. 7. Stop ring has a constant cross-section of single rings, installed in the ring ditch, a roller bearing or the shaft in the axial position inside the enclosure. 8. Locking ring has a constant cross-section of single rings, mounted on the ring ditch as a roller or ring to keep the bearing cage. 9. Every circle is a circular parts, for two washers between the bearing rings or bearings or bearing rings or between the two half bearing washer between the two halves so that they are provided between the axial distance. 10. Ring formed by one or more parts of the ring cover, fixed to the bearing washer and a ring or rings or gaskets with another contact or the formation of the labyrinth of narrow gap, to prevent oil leakage and foreign matter. 11. Dust cover is a circular cover, usually made of sheet metal stamping, fixed in a ring or a washer bearing on, and extends towards the other rings or washers, hidden inside the bearing space, but not with another ring or gasket contact. 12. Retainer ring attached to the inner ring or shaft of a part, using centrifugal force to enhance the bearing capacity to prevent foreign matter. 13. Rolling in the groove between the rolling ball or roller. 14. Retainer part or parcel number of rolling, and with the movement of bearing parts together, to isolate rolling, and rolling guide and usually keep their bearings.

Combination of three-row roller slewing bearing (slewing ring)

Three-row roller slewing ring has three seat down and separated from their respective radial groove, making the load of each row of rollers can be determined exactly, can withstand the various load carrying capacity is four products in the largest of the shaft, the radial structure of firm sizes are larger, especially for applications that require large diameter heavy-duty machinery, such as bucket wheel excavators, wheeled cranes, ship cranes, ladle turret, and large-tonnage cranes and other machinery on.

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.

The assembly is very easy to open, the upper and lower bearing raceway arc angles is 90 °, can withstand large axial forces and tipping moment. When the radial force is greater than 0.1 times the axial force to be specially designed raceway. Double-row slewing bearing axial and radial dimensions are large, solid structure, especially for applications that require above average diameter of the tower cranes, truck cranes and other handling machinery.

Single-row crossed roller slewing bearing (slewing ring)

Single-row crossed roller slewing ring, composed of two seat, compact, light weight, high precision manufacturing and assembly space is small, the installation of high precision cross-roller arrangement of 1:1, can withstand the axial force, the larger radial force and tipping moment. Are widely used in lifting the transport, construction machinery and military products.

Single-row four point contact ball slewing bearing (slewing ring)

Single-row four point contact ball bearing slewing ring formed by the two seat, compact, light weight, ball and four-point arc raceway contact, can withstand the axial force, radial force and tilting moment. Rotary transfer machines, welding operation machine, small and medium sized construction machinery such as cranes and excavators can be used.

Wheel bearing seal

Wheel bearing seal on the one hand has been filled with grease to prevent leaking, the other is to prevent outside dust, impurities and moisture intrusion inside the bearing affect their work. In slewing bearing most of the heavy work at low speed, so the seal type bearings with rubber seals and labyrinth seals two structures. The rubber seal structure itself has a simple structure, small space, sealing performance and reliable and has been widely used, but the downside is that when the rubber seal at high temperature aging of early loss of lip seal and easy, so at high temperatures work under working conditions should be adopted turntable bearing labyrinth seal.
