What is the significance of tapered roller bearings?

Tapered roller bearings are dismountable bearings, and both the inner and outer rings of the bearing have tapered raceways. Depending on the number of installed roller rows, this type of bearing is divided into different designs such as single row, double row and four row tapered roller bearings.

What is the workflow for tapered roller bearings?

The inertial force of the tapered roller bearing and cage, as well as friction in the lubricant, impair the rolling and rotational accuracy of the bearing, and sliding movement between the rollers and the raceway may be detrimental to the bearing. The minimum load required for a tapered roller bearing Fmin can be estimated according to the following formula: Fmin0.02C, where dynamic load capacity, when starting at low temperatures or at high temperatures a greater load may be required Lubricant viscosity Minimum load. Often the weight of the bearing itself plus the load on the bearing exceeds the required minimum load. If the minimum load has not been reached, this bearing type must be subjected to additional radial load, such as axial preload of the bearing, in order to meet the minimum load requirements.


Why should tapered roller bearings be lubricated?

Premature failure of tapered roller bearings due to improper lubrication accounts for more than a third of the failure causes of tapered roller bearings. Sufficient grease can form an oil film between the contact surface of the rolling element and the raceway during the operation of the bearing, thereby reducing the rise of the friction temperature and the wear of the contact surface. Choosing the right bearing grease is the basis for stable bearing operation and maximum reliability.



What are the performance characteristics of tapered roller bearings?

Tapered roller bearings are mainly used to carry radial and axial combined loads, which are mainly based on radial loads. In general, it is not suitable to carry axial loads alone. This type of bearing can be installed with inner rings (with full set of rollers and cages) and outer rings. This type of bearing does not allow the shaft to tilt relative to the housing, and under the radial load an additional axial force is generated. The size of the axial clearance of this type of bearing has a big relation to whether the bearing can work normally. If the axial clearance is too small, the temperature rise is high; If the axial clearance is large, the bearing is easily damaged. Therefore, special attention should be paid to the adjustment of the axial clearance of the bearing during installation and operation. If necessary, pre-press assembly can be carried out to increase the rigidity of the bearing.
