Taper Roller Bearing's Design

➔ Taper roller bearings have

>> Inner ring raceway >> Outer ring raceway>> Tapered rollers

➔ It is designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

➔ The projection lines of the raceways meet at a common point on the bearing axis to provide true rolling and low friction.

Taper Roller Bearing's Design

➔ The axial load carrying capacity of tapered roller bearings increases with increasing contact angle . α

➔ The size of the angle is related to the calculation factor e.

➔ The larger the value of e, the larger the contact angle.

➔ A single row tapered roller bearing is typically adjusted against a second tapered roller bearing.

Single Row Taper Roller Bearings

➔ Single row tapered roller bearings are separable as shown in figure.

➔ That is the inner ring with roller and cage assembly (cone) can be mounted separately from the outer ring (cup).

Components

➔ Taper Roller Bearings are separatble and have the following components :

- Outer Ring

- Inner Ring

- Roller assembly

➔ Roller assembly is containing the rollers and a cage

Components

➔ The non-separable inner ring and roller assembly is called the cone, and the outer ring is called the cup.

➔ Internal clearance is established during mounting by the axial position of the cone relative to the cup.

Applications

➔ In many applications tapered roller bearings are used in back-to-back pairs so that axial forces can be supported equally in either direction.

➔ Pairs of tapered roller bearings are used in car and vehicle wheel bearings where they must cope simultaneously with large vertical (radial) and horizontal (axial) forces.
