Tapered roller bearings belong to the separation type bearings, bearing the inner and outer ring have tapered raceway, its inner ring and a set of tapered rollers by the basket-shaped keep frame envelope into an inner ring assembly, the outer ring can be separated from the inner ring assembly, tapered roller bearings between the outer ring and the inner component is 100 percent can be universal interchangeable use, bearing designed to adapt to the combined load, that is, the simultaneous action of radial and axial load, the raceway extension line The extensions of the raceways intersect at the same point on the axis of the bearing to achieve true rolling and therefore low frictional torque during operation. The axial load capacity of tapered roller bearings increases as the contact angle increases. The size of the contact angle is related to the calculation coefficient, the higher the value, the greater the contact angle.
Single tapered roller bearing can bear radial load and single direction axial load, axial load capacity depends on the contact angle, namely the outer ring raceway angle, the larger the angle, the greater the axial load capacity. When bearing radial load, will produce an axial force, so when another can bear the opposite direction of the axial force bearing to be balanced, compared with angular contact ball bearings, bearing capacity increased, the limit speed is reduced.
