What is a tapered roller bearing
Tapered roller bearings are separable bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single-row, double-row, and four-row tapered roller bearings according to the number of rows installed. Single row tapered roller bearings can bear radial load and single direction axial load. When the bearing bears the radial load, it will produce an axial component force, so when it needs another bearing that can bear the axial force in the opposite direction to balance it.
Tapered roller bearings refer to radial thrust rolling bearings with tapered rollers as rolling elements. There are two kinds of small cone angles and large cone angles. The small cone angle mainly bears the combined radial and axial load based on the radial load. It is often used in double use, reverse installation, the inner and outer races can be installed separately, and the radial and axial clearance can be adjusted during installation and use; The large taper angle mainly bears the combined axial and radial load mainly based on the axial load. Generally, it is not used to bear the pure axial load alone, but can be used to bear the pure radial load when configured in pairs (the ends of the same name are installed relative to each other).
The ability of single-row tapered roller bearings to withstand axial load depends on the contact angle, that is, the outer ring raceway angle. The larger the angle, the greater the axial load capacity. The most used tapered roller bearing is the single-row tapered roller bearing. Small-sized double-row tapered roller bearings are used in the front wheel hubs of cars. Four-row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills.
Tapered roller bearings application
Tapered roller bearings are mainly subjected to combined radial and axial loads based on the radial direction. 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 is a separable bearing, which is divided into single-row, double-row, and four-row tapered roller bearings according to the number of rows of rolling elements in the bearing. The clearance of single-row tapered roller bearings needs to be adjusted by the user during installation; the clearances of double-row and four-row tapered roller bearings have been set at the factory according to user requirements and do not require user adjustment.
The tapered roller bearing has a tapered inner ring and an outer ring raceway, and the tapered rollers are arranged between the two. All the projection lines of the cone surface converge at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for bearing compound (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle α; the larger the angle α, the higher the axial load capacity. The size of the angle is expressed by the calculation coefficient e; the greater the value of e, the greater the contact angle, and the greater the applicability of the bearing to bear the axial load.
Tapered roller bearings are usually separated, that is, the tapered inner ring assembly composed of the 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 automobiles, rolling mills, mining, metallurgy, plastic machinery, and other industries.
