Do you know the structural characteristics of tapered roller bearing cup and cone?

3,529 Published by Nov 14,2022

Tapered roller bearing cup and cone mainly bear radial and axial combined loads. The bearing load carrying capacity depends on the raceway angle of the outer ring, the larger the angle, the greater the load carrying capacity. Tapered roller bearings are widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other industries. This article briefly introduces the advantages of tapered roller bearings, the classification of tapered roller bearings, and the structural characteristics of tapered roller bearings for everyone to understand.

The most used of tapered roller bearing cup and cone are single row tapered roller bearings. In the front wheel hub of the car, small double-row tapered roller bearings are used. Four-row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills.

Advantages of tapered roller bearings

Tapered roller bearings mainly bear radial and axial combined loads. The bearing load carrying capacity depends on the raceway angle of the outer ring, the larger the angle, the greater the load carrying capacity. This type of bearing is a separable type bearing and is divided into single, double and quadruple rows of 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; Double and four row tapered roller bearing clearance has been given according to user requirements at the time of delivery and does not require user adjustment.

Tapered roller bearings have a tapered inner ring and an outer ring raceway in between. The projection lines of all tapered surfaces converge at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for composite (radial and axial) loads. The axial load capacity of a bearing is largely determined by the α contact angle; The greater the α angle, the higher the axial load capacity. The angle size is expressed by the calculation factor e; The greater the e-value, the greater the contact angle and the greater the suitability of the bearing for axial loads.

Tapered roller bearings are usually separable, i.e. a tapered inner ring assembly consisting of an inner ring with rollers and a cage assembly can be mounted separately from the tapered outer ring (outer ring).

Tapered roller bearing structural features

The type type number for tapered roller bearings is 30000, and tapered roller bearings are separable bearings. In general, especially in the size range of tapered roller bearings in GB/T307.1-94 "Rolling bearing radial bearing tolerances" is 100% interchangeable between the outer ring and the inner component.

The angle of the outer ring and the diameter of the outer raceway have been standardized to be the same as the external dimensions. Changes are not allowed at design and manufacturing time. This results in a worldwide interchangeability between the outer ring and the inner assembly of tapered roller bearing cup and cone.

Tapered roller bearing cup and cone are mainly used to accommodate combined radial and axial loads that are mainly radial loads. Compared with angular contact ball bearings, the load carrying capacity is large and the limiting speed is low. Tapered roller bearings are capable of accommodating axial loads in one direction and are able to limit axial displacement in one direction of the shaft or housing.
