Function and application of tapered roller bearing

Tapered roller bearings have tapered inner ring and outer ring raceways, with tapered rollers arranged between them. The projection lines of all conical surfaces meet at the same point of the bearing axis. This design makes tapered roller bearings particularly suitable for bearing complex (radial and axial) loads. The axial load capacity of bearing is mainly determined by contact angle α Determined; α The greater the angle, the higher the axial load capacity. The angle is expressed by the calculation coefficient e; The larger the e value is, the larger the contact angle is, and the greater the applicability of bearing to bear axial load is.

Tapered roller bearings are usually of separate type, that is, the tapered inner ring assembly consisting of an inner ring with roller and cage assembly can be installed separately from the tapered outer ring (outer ring).

Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.

The secondary reasons for the scar of tapered roller bearing in the process of installation are: the inner ring and outer ring of the bearing are skewed during installation and assembly; Or it may be the emerging load in the process of installation and assembly, which finally forms the bearing emerging scar.

When installing tapered roller bearings, it should be stopped according to the working specifications to avoid many problems. If the form or method of the device is not correct, linear scars will be formed on the raceway surface and rolling surface of the bearing. The device of deep groove ball bearing indirectly reflects the precision, life and function of the bearing when it is used.

Although the quality of tapered roller bearings and other aspects are relatively good, rolling bearings are precision components, and their use must be carried out with corresponding caution. No matter how high performance bearings are used, if they are used improperly, they will not achieve the expected high performance. Precautions for the use of bearings are as follows:

(1) Keep tapered roller bearings and their surroundings clean.

Even small dust that cannot be seen by the eyes will bring bad effects to the bearing. Therefore, keep the surroundings clean to prevent dust from invading the bearing.

(2) Use with caution.

When the tapered roller bearing is strongly impacted in use, it will produce scars and indentations, which will become the cause of the accident. In serious cases, cracks and fractures may occur, so attention must be paid.

(3) Use appropriate operating tools.

Avoid replacing existing tools and use appropriate tools.

(4) Pay attention to the corrosion of tapered roller bearings.

When operating the bearing, the sweat on the hands will be the cause of rust. Pay attention to the operation with clean hands, and wear gloves as much as possible.
