The invention relates to a high-axial-force deep groove ball bearing which comprises an outer ring, an inner ring, an outer retainer, an inner retainer and a plurality of steel balls. The inner surface of the outer ring comprises a first cylindrical surface, a second cylindrical surface and a plurality of first curved surfaces with arc sections. The outer surface of the inner ring comprises a third cylindrical surface, a fourth cylindrical surface and a plurality of second curved surfaces with arc sections. The outer retainer and the inner retainer are matched in a clamped mode and arranged between the outer ring and the inner ring. According to the high-axial-force deep groove ball bearing, through the structural design of the inner retainer and the outer retainer, the structure of first arc-shaped openings in the outer retainer, the structure of second arc-shaped openings in the inner retainer, and steel ball containing spaces formed by the first curved surfaces of the outer ring and the second curved surfaces of the inner ring, the capability of the bearing to bear axial force is increased by about three times, and the performance of the bearing is improved.
Description
technical field [0001] The invention belongs to the technical field of bearings, relates to the technical field of bearings for automobiles, in particular to a deep groove ball bearing with high axial force and its application. Background technique [0002] The rolling of the car wheel is realized by the bearing between the hub and the steering knuckle in the hub unit. During the movement of the vehicle, the bearing not only bears the radial force but also bears the axial force. The bearings in the current automobile hub unit are mainly tapered roller bearings and steel ball bearings. [0003] In the process of automobile design, try to reduce the friction of the mechanical system, improve the mechanical efficiency, save fuel and reduce emissions. The rolling friction coefficient of steel ball bearings is smaller than that of tapered roller bearings, but the ability of steel ball bearings to withstand axial force is poor, so they can only be used in small vehicles. Tapere...
