Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Example 1
As shown in fig. 1-5, a deep groove ball bearing comprises an outer ring 1, an inner ring 2 arranged in the outer ring 1, a cage 3 arranged between the outer ring 1 and the inner ring 2, and rolling bodies 4 arranged in pockets 3.3 of the cage 3; the retainer 3 is in a steel ball guiding form, the retainer 3 comprises a retainer seat 3.1 and a retainer cover 3.2, the retainer seat 3.1 is buckled with the retainer cover 3.2 to form a plurality of pockets 3.3, specifically, each pocket 3.3 is formed by buckling concave spherical surfaces respectively arranged on the retainer seat 3.1 and the retainer cover 3.2, a rolling body 4 in each pocket 3.3 is respectively provided with a contact point with each concave spherical surface, and the radial orthographic projection surface of each pocket 3.3 is similar to an ellipse. When the cage 3 is used, when the rolling bodies 4 roll on the raceways of the outer ring 1 and the inner ring 2, one contact point is respectively arranged between each rolling body and each concave spherical surface in the pocket 3.3, and the cage 3 body is guided by two-point contact between the rolling bodies 4 and the pockets 3.3, so that the cage operates more stably.
The buckling surfaces of the retainer base 3.1 and the retainer cover 3.2 are provided with mutually matched positioning shoulders, specifically, the buckling surface of the retainer base 3.1 is provided with a first positioning shoulder 3.1a, the buckling surface of the retainer cover 3.2 is provided with a second positioning shoulder 3.2a, and the first positioning shoulder 3.1a and the second positioning shoulder 3.2a are buckled to form a stepped buckling surface. During installation, the retainer seat 3.1 and the retainer cover 3.2 are quickly positioned in the radial direction and the axial direction through the positioning circular bead, and can effectively prevent mutual radial movement after being fixed, so that the bearing capacity of the bearing is improved, and the service life of the bearing is prolonged.
