Antifriction design method for tapered roller bearing

An antifriction design method for a tapered roller bearing comprises the following steps: firstly, carrying out stress analysis on the tapered roller bearing under a certain working condition, establishing a mechanical equilibrium equation, solving deformation parameters of the bearing, and solving the sum of offsets generated by influences of the deformation parameters and bearing structure parameters on three-line intersection points; the absolute value of the product of the contact load of the roller and the outer ring and the offset of the three-line intersection points is used for reflecting the friction temperature rise caused by stress deformation, and the overall QeL value of the bearing is reduced by adjusting the design tolerances of the diameter of the roller of the bearing, the diameter of a raceway of the inner ring, the thickness of a large flange of the inner ring, the angle of the raceway of the outer ring and the angle of the raceway of the inner ring. Meanwhile, the requirement for high asse
