- Abstract
Taking QJ214 four point contact ball bearings as research objects, an optimization model is established with dynamic load rating and friction torque of the bearings as objective functions, and curvature radius coefficient of inner raceway and outer raceway, diameter of steel ball, pitch diameter of ball set and original contact angle of the bearings as design variables. The genetic algorithm is used to optimize the bearings, and the change of contact angle of the bearings is studied based on quasi-static model of the bearings. After optimization, curvature radius coefficient of inner raceway and outer raceway, diameter of steel ball, pitch diameter of ball set, contact angle are respectively 0.520, 0.531, 17.600 mm, 97.811 mm, 35, and the optimized working contact angle of the bearings is greater than gasket angle. The results show that the dynamic load rating increases by 1.592%, and the frietion torque decreases by 4.051%.
