Tapered roller bearing

Conical roller bearings belong to separable bearings, with tapered raceways on both the inner and outer rings. The outer ring can be separated from the inner ring component, and the bearing is designed to adapt to combined loads, namely radial and axial loads acting simultaneously. The extension lines of the raceways intersect at the same point on the bearing axis to achieve true rolling, thus having low friction torque during operation. The axial load capacity of tapered roller bearings increases with the increase of contact angle. The size of the contact angle is related to the calculation coefficient, and the larger the value, the larger the contact angle.

Single row tapered roller bearings can withstand radial loads and unidirectional axial loads. The axial load capacity depends on the contact angle, that is, the outer raceway angle. The larger the angle, the greater the axial load capacity. The tapered roller bearing adopts an optimized three convex design method. By simulating the working conditions, suitable convexity requirements are found to reduce contact stress and improve the fatigue life of the bearing.
