A brief introduction to tapered roller bearings

 

 

Abstract:

Tapered roller bearings mainly bear combined radial and axial loads, which are mainly radial. The load-bearing capacity of the bearing depends on the raceway angle of the outer ring. The larger the angle, the greater the load-bearing capacity. This type of bearing is a separable bearing and 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 clearance of double-row and four-row tapered roller bearings has been set according to user requirements before delivery and does not require user adjustment. “

A brief introduction to tapered roller bearings

Tapered roller bearings mainly bear combined radial and axial loads, which are mainly radial. The load-bearing capacity of the bearing depends on the raceway angle of the outer ring. The larger the angle, the greater the load-bearing capacity. This type of bearing is a separable bearing and 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 clearance of double-row and four-row tapered roller bearings has been set according to user requirements before delivery and does not require user adjustment. “

Tapered roller bearings have conical inner and outer raceways, with tapered rollers arranged between them. The projection lines of all conical surfaces converge at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for carrying combined (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle α; the larger the α angle, the higher the axial load capacity. The size of the angle is expressed by the calculation coefficient e; the larger the value of e, the larger the contact angle, and the greater the suitability of the bearing for bearing axial loads. Tapered roller bearings are usually of the separable type, that is, the tapered inner ring assembly consisting of an inner ring with a 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.
