Slewing Bearings

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

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.

 

 

Wheel bearings use:

1. Trailer: This type of bearings used in several applications, the most important used in the transport sector, agricultural trailers, irrigation systems and airport luggage rack. The application of the vehicle, passing the bearing axial load, radial load and torque. In other applications, most of them are transferring axial load. Jinyuan manufacturing trailers wheel bearings. 2. Wind power: wind turbine bearings typically include yaw bearings, pitch bearings, transmission bearings (main shaft and gearbox bearings.) Jin and Yuan to provide the yaw bearing and the pitch bearings. Tower and yaw bearings installed in the cockpit of the junction, pitch bearings installed in each blade root and hub joints. Each wind turbine with a pitch yaw bearings and three sets of bearings. 3 Solar energy: solar panel rotation is a good increase in energy solutions. As Jin and Yuan has a very compact bearing design, supply, Europe's largest solar farm. 4. Medical devices; j, Jin and Yuan developed high-precision bearings, low noise, high life, high reliability, series of wheel rotation spindle bearing medical devices, has been widely used in gamma knife, CT machines, MRI machines and other medical equipment . 5. Robot: Industrial robots and other equipment. Jinyuan wheel bearings installed in the robot joints, this structure can be incredibly high in close rotation.

Turntable rotation bearing material: 50Mn, 42CRMO, GCR15SIMN, 9CR18MO wheel bearings precision: P0, P6, P5, P4, P2 accuracy from low to high, the price will be from low to high.

 

 

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.
