Problems solved by technology
Due to the inherent defects of the cold heading process, the end face of the rivet head and the end face of the bearing cage are not tightly bonded, and gaps are likely to occur
During the use of the bearing, vibration is prone to occur, resulting in fretting wear between the rivet and the bearing cage, causing the rivet to fail in advance, further causing the bearing to fail, thereby reducing the reliability of the entire mechanical equipment

The invention discloses a bearing retainer riveting device and a riveting method. The bearing retainer riveting device comprises a tool base; the limiting groove is formed in the tool base and used for containing an inner ring of a bearing to be riveted; the supporting ring is arranged on the outer side of the limiting groove and used for placing a retainer of the bearing to be riveted; the positioning holes are formed in the supporting ring and used for positioning the riveting columns, and the riveting columns are installed in the riveting holes in the retainer and inserted into the positioning holes to be positioned. Compared with the prior art, the bearing retainer riveting device and the riveting method provided by the invention have the advantages that a straight-rod rivet without a rivet head can be riveted, the structure is simple, the operation is convenient, and the reliability of a bearing is higher.
Description
technical field [0001] The present application relates to the technical field of bearing cage installation, and more specifically, to a riveting device and riveting method for a bearing cage. Background technique [0002] Bearing is an important part that supports the rotating body in the process of mechanical transmission. It is used to reduce the friction coefficient of mechanical load during the operation of the equipment and reduce the energy consumption of mechanical equipment. The bearing mainly includes the inner ring of the bearing and the outer surface of the bearing. Ring, cage and rolling body, the cage is located between the inner ring of the bearing and the outer ring of the bearing, the rolling body is installed in the pocket of the cage, the main purpose of the cage is to keep the rolling bodies at an appropriate distance from each other, It can prevent the rolling elements from colliding and rubbing against each other during work. [0003] When the bearing c...
