Why does tapered roller bearing produce noise during use?
- 2025-03-03
Conical roller bearings mainly bear radial and axial combined loads, and the bearing capacity depends on the raceway angle of the outer ring. The larger the angle, the greater the bearing capacity. This type of bearing belongs to the separated type bearing, which is divided into single row, double row, and four row tapered roller bearings according to the number of rolling elements in the bearing. The clearance of single row tapered roller bearings needs to be adjusted by the user during installation; The clearance of double row and four row tapered roller bearings is given according to user requirements at the time of product delivery and does not require user adjustment.
Conical roller bearings have conical inner and outer raceway, with tapered rollers arranged between the two. The projection lines on the conical surface converge at the same point along the bearing axis. This design makes tapered roller bearings suitable for withstanding composite (radial and axial) loads. The axial load capacity of bearings is largely determined by the contact angle α; The larger the alpha angle, the higher the axial load capacity. The angle size is represented by the calculation coefficient e; The larger the value of e, the greater the contact angle, and the greater the applicability of the bearing to withstand axial loads.
Conical roller bearings are usually of the separated type, which means that the conical inner ring assembly consisting of rollers and cage components can be installed separately from the conical outer ring (outer ring). Conical roller bearings are widely used in industries such as automobiles, rolling mills, mining, metallurgy, and plastic machinery.
The secondary reason for the appearance of scratches on tapered roller bearings during the installation process is that the inner and outer rings of the bearing are skewed during installation and assembly; Or perhaps it is the emergence of charging loads during the installation and assembly process, ultimately forming bearing burst marks.
When installing tapered roller bearings, it is necessary to stop according to the working specifications. If the form or method of the installation is not appropriate, it will cause linear scratches on the raceway surface and groove surface of the bearing. The device of deep groove ball bearings indirectly reflects the precision, lifespan, and functionality of the bearings during operation.
