Taper roller bearing design
Tapered roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The
Projection lines of all the tapered sufaces meet at a common point on the bearing axis. Their design makes taper roller
Bearings particularly suitable for the accommodation of combined (radial and axial) loads.
Inner ring (cone), an outer ring (cup), a cage and rollers which are profiled to distribute the load evenly.
They have high radial and axial (thrust) load capacities at low to intermediate speeds.
Classification and Models of Tapered Roller Bearings:
1. Single-row Tapered Roller Bearings (30000 series)
Note: Carry radial loads based joint loads of radial loads and axial joint loads. Bearings with big cone angle
Withstand radial loads based radial loads and axial joint loads, generating added axial force under radial loads.
Therefore, they are arranged in pairs to take radial loads. The external axial force shall be larger than
Additional axial force for exclusive use. 313 series bearings has big contact angle (from 27° To 30° ), for taking
Large axial loads. Contact angle of other series of bearings is from 10° To 18° .
2. Double Row Tapered Roller Bearings (35000 series)
Note: This type of bearings has an outer ring and two inner rings, between which spacer ring is arranged. The
Clearance is adjusted by changing thickness of spacer ring. The bearings are capable of taking both radial
And axial loads in two directions. The axial deflection in two directions of shaft and housing could be limited
Among bearing clearance range.
3. Four Row Tapered Roller Bearings (330000 series)
Note: This type of bearings has spacer rings for adjusting clearance in both inner rings and outer rings. Similar
To the performance of double row tapered roller bearings, they have large load carrying capability and low limit
Speed. They are mainly used in heavy machinery, such as rolling mills etc.
Application
Taper roller bearing could used in automobiles, high-precision machine tool, high frequency motor, centrifuge, gear spindle, etc.
Single row tapered roller bearings compose of a outer ring and a inner ring with a group of conical roller
Sustained by basket shape cage. Outer and inner ring components can be separated, according to the
Rule of ISO conical roller bearing outline dimension standard, any conical roller bearing with standard model
Can be interchanged by it's inner or outer ring internationally. That's means the same model outer ring, except
External dimension and tolerance should accord with ISO492 (GB307) regulation, Inner ring components of
Coning angle and component cone diameter and so on must comply with the relevant provisions of the
Exchange too.
