Installation Methods and Suggestions for Tapered Roller Bearings

What is tapered roller bearing
The ability of a single row tapered roller bearing to bear axial load depends on the contact Angle, that is, the outer ring raceway Angle. The greater the Angle, the greater the axial load capacity. The largest amount of tapered roller bearings is single row tapered roller bearings. Double row tapered roller bearings of small size are used in the front wheel hub of the car. Four rows of tapered roller bearings are used in heavy machines such as large cold and hot rolling mills.

Structural characteristics of tapered roller bearings
1. Tapered roller bearings are separated bearings. In general, especially in the "Rolling Bearings Centripetal Bearing Tolerances", the outer ring and inner component of tapered roller bearings within the size range involved are 100% universal and interchangeable.
2. The Angle of the outer ring of tapered roller bearings and the diameter of the outer raceway have been standardized as well 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.
3. Tapered roller bearings are mainly used for bearing combined radial and axial loads, which are mainly radial loads. Compared with angular contact ball bearings, the bearing capacity is large and the limit speed is low.

Installation method for tapered roller bearings
Put the small end of the bearing into the journal first, and install the bearing to the specified position to be fixed by tapping the large end surface. According to the bearing size and working condition, the current bearing installation mostly adopts two forms of cold installation and hot installation. Cold method installation generally adopts some auxiliary tools to install bearings; Thermal installation generally adopts heating method to make the inner diameter of the bearing expand for installation.

Installation recommendations for tapered roller bearings
1. It is suggested that when installing the bearing, the user can choose the appropriate assembly mode, such as cold or hot, according to the bearing size and working condition. When the cold installation is used, the installation sleeve should be used with the installation as far as possible, which can effectively avoid abnormal impact on other positions of the bearing and ensure that the end face and journal are vertical when the bearing is installed. When the field can not be installed by the sleeve, the copper rod should be placed on the inner ring of the bearing, and the hammer should be used to beat it symmetrically and circulatively in the diameter direction. It should not be too hard, and it should be paid attention not to bear the impact on other positions other than the inner ring of the bearing.
2. Improve the installation technology of installers, operate in accordance with the correct requirements of bearing installation, and prevent the damage of bearings caused by operation errors, especially violent operation.
