The advantages of taper roller bearing

Tapered roller bearing inner ring and outer ring of tapered roller, roller for cone type, type of bearings is separable. Main structural form in scroll to mention the number of columns are: divided into single row taper roller bearings, double row taper roller bearings, four row circular cone roller bearings.

According to the contact Angle of the size of the division are:

Small cone Angle (9 ° < a 25 ° or less)

Big cone Angle (> 25 °)

Tapered roller bearing the axial bearing capacity depends on the contact Angle of a, both outer ring raceway Angle, the bigger the contact Angle of a, the greater the axial bearing capacity. Angle size by calculating coefficient of e, e value, the greater the contact Angle is larger.

Generally are not allowed to have tilted axis relative to the shell hole, if you have tilted the biggest no more than 2 ". Because such as the production process requirements, needs as a rolling bearing of rolling mill, inevitably will be affected by the force of bending roll and axis tilted more than 2 ", bearing roller and race will generate additional stress, thus increase the bearing load and shorten the service life of bearing. So DMD tapered roller bearing roller and raceway contact shape with modification, especially the rolling mill with four row circular cone roller bearings, besides has the contact shape modification, the columns clearance and the inner ring with roller neck and contact all have special design, can effectively solve the problem caused by the force of bending roll bearing life expectancy. Double row tapered roller TDI structure (series 370000) two outer ring, the inner ring and outer ring of the spacer ring, clearance by circle, to adjust the thickness of the insulation thickness of baffle can be used to adjust the double row circular cone roller bearings of interference. Its performance with two single row circular cone roller bearings installation performance similar to face to face, and export-oriented double row circular cone roller bearings TDO structure (series 350000), compared with less space for installation, but is a bit poor rigidity, neutral not sensitive compared to the right.
