Tapered roller bearings belong to separate type bearings, and both the inner and outer rings of the bearings have tapered raceways. This type of bearing is divided into different structural types based on the number of rows of installed rollers, such as single row, double row, and four row tapered roller bearings. Single row tapered roller bearings can withstand radial loads and axial loads in a single direction. When the bearing is subjected to radial load, an axial component will be generated, so another bearing that can withstand the opposite axial force is needed for balance.
The ability of a single row tapered roller bearing to withstand axial load depends on the contact angle, i.e. the angle of the outer ring raceway. The larger the angle, the greater the axial load capacity. The most commonly used tapered roller bearing is a single row tapered roller bearing. In the front wheel hub of a sedan, small-sized double row tapered roller bearings are used. Four row tapered roller bearings are used in heavy-duty machines such as large cold and hot rolling mills.
1.APPLICATION FEATURES
.
(1)Has a high load carrying capacity, and is able to withstand a certain degree
of axial impact load.
(2)
Need to ensure the service life of bearings under a high
load;Initially, bearings lubricated by grease, and later use oil to lubricate.
2.PERFORMANCE.
(1)
The service life is relatively high under high loads, general requirements of 3~5 times theory life.
(2)
In the gearbox, foreign matters can enter bearings easily, require bearings have a high compressive strength and wear resistance.
3.ADVANTAGE
.
To ensure the service life, we have made improvements in the following two aspects:
(1)
Rings manufactured by high-purity specialty quality bearing steel.
(2)
Steel balls are from famous brand manufactures, that effectively guarantee materials and processing accuracy.
(3)
The bearing rings are manufactured by high speed forging +cold rolling, and do Nitrocarburizing on the raceway surface.
4.Design Structures.
(1)
Sealed with tri-lips light contact structure -- having a high sealing performance, and suitable for high-speed operation.
(2)
Using oil reservoir structured cages -- increase the lubrication capability of bearings.
(3)
Optimize the groove curvature of outer ring and the raceway of inner ring -- suitable for high-speed and reduce axial movement.
(4)
Both inner and outer bearing rings of high-emission vehicles are used forging process or nitriding treatment -- increase raceway strength, improve crush resistance, and abrasion resistance.
