Tapered Roller Bearing Structure And Installation Knowledge

What is tapered roller bearings

Tapered roller bearings refer to radial thrust rolling bearings with tapered rollers. There are small cone angles and large cone angles. The small cone Angle mainly bears the combined radial and axial load, which is mainly radial load. It is often used in double use and installed in reverse. The inner and outer seat rings can be installed separately, and the radial and axial clearance can be adjusted during installation and use. The large cone Angle mainly bears the combined axial and radial loads which are mainly axial loads. Generally, it is not used to bear the pure axial load alone, but can be used to bear the pure radial load when it is configured.

Characteristics of tapered roller bearings

Tapered roller bearings are mainly used to bear radial load and axial combined load.Compared with angular contact ball bearings, the bearing capacity is large and the limit speed is low.Tapered roller bearings are capable of bearing axial loads in one direction and can limit the axial displacement of the shaft or housing in one direction.

Application of tapered roller bearings

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

Tapered roller bearing structure and installation knowledge

Structure of tapered roller bearings: the type code of tapered roller bearings is 30000, tapered roller bearings are separated bearings. In general, especially in GB/T307.1-94 "Rolling Bearings Centripetal Bearing Tolerances" involved in the size range of tapered roller bearings between the outer ring and the inner component is 100 percent universal interchangeable use.

The Angle of the outer ring and the diameter of the outer raceway have been standardized as the outer dimension. It is not allowed to change during design and manufacture. In order to make the taper roller bearing between the outer ring and the inner component can be used in the world.

Tapered roller bearings are mainly used to bear radial load and axial combined load. Compared with angular contact ball bearings, the bearing capacity is large and the limit speed is low. Tapered roller bearings are capable of bearing axial loads in one direction and can limit the axial displacement of the shaft or housing in one direction.

Installation of tapered roller bearings: adjust the axial clearance for the installation of tapered roller bearings, the axial clearance can be adjusted by adjusting nuts on the journal, adjusting gaskets and threads in the bearing seat holes, or by means of pre-tightening springs. The size of axial clearance is related to the arrangement of bearing installation, the distance between bearings, and the material of shaft and bearing seat, which can be determined according to the working conditions.

For tapered roller bearings with high load and high speed, when adjusting clearance, the influence of temperature rise on axial clearance must be taken into account, and the clearance reduction caused by temperature rise should be estimated. In other words, the axial clearance should be appropriately adjusted to a larger extent.

For bearings with low speed and vibration, no clearance installation should be adopted, or pre-load installation should be applied. The purpose is to make the roller and raceway of tapered roller bearings have good contact, the load is evenly distributed, and to prevent the roller and raceway from being damaged by vibration impact. After adjustment, the size of axial clearance is checked by dial gauge.
