Tapered roller bearing structural features

Tapered roller bearings are mainly exposed to the radial diameter, axial load. Load bearing capacity depends on the outer ring raceway angle, angle the greater carrying capacity. This kind of bearing is a separate type bearings, according to the number of columns bearing rolling elements into single row, double row and four-row tapered roller bearings. Single row tapered roller bearing clearance to be adjusted during installation; double row and four-row tapered roller bearing clearance in the factory based on user requirements given, not to be user adjusted.
Tapered roller bearings have tapered inner and outer ring raceways, tapered roller arranged between the two. All conical surface projection lines in the bearing axis with a little together. This design makes tapered roller bearings particularly suitable for bear compound (radial and axial) loads. Most of axial load bearing capacity is determined by the contact angle α; α angle the greater the axial load capacity is higher. Angle size to calculate the coefficient of e said; e larger the value, the greater the contact angle, the bearing axial load greater applicability.
Tapered roller bearings are usually separated type, that is with roller and cage assembly of inner components of the cone with the conical outer ring (outer ring) installed separately.
Tapered roller bearings are widely used in automotive, mill, mining, metallurgy, plastics machinery and other industries.
Tapered roller bearings are in the process means the emergence of scars secondary reason is: bearing means being sprung When assembling the inner and outer skew; or perhaps the process of being assembled in the device and load the emergence of strikes, culminating in the emergence of bearing scars .
When the device is in accordance with tapered roller bearings to stop work norms, not to form a number of achievements, such as the form or when there is no way means, Gulu and raceway bearing surface formed on the emergence of the linear bearing scars will form. Deep groove ball bearing means indirect response to the precision, the number and function of bearing life during use.
All aspects of tapered roller bearings are better quality though, but the rolling bearings are precision components, its use should also be carefully carried out. Regardless of how high-performance bearings, if used improperly, it will not get the expected performance.
