Description

Grooving device for tapered roller bearing retainer

Technical Field

The utility model belongs to the technical field of bearing processing, and particularly relates to a grooving device for a retainer of a tapered roller bearing.

Background

At present, tapered roller bearings are widely used in various industries in the mechanical field, and are a standard part commonly used in mechanical equipment. Roller bearings are widely available, but most of the conventional roller bearings include an inner ring with rollers and a bearing cage and a separable inner ring, and the bearing cage functions to partition and fix the rollers, prevent contact between the rollers, provide a lubrication space, and guide the rollers to roll, thereby minimizing friction and heat generation. The bearing cage has a plurality of equidistant windows for isolating and guiding the rollers, wherein the connection between the windows, called a window beam, serves to connect and increase the strength of the cage.

The tapered roller bearing retainer structure is influenced by the small flanges of the roller and the inner ring, and the retainer hole beam is forced to be bent and deformed by an expansion process before assembly so as to be smoothly installed in the roller and the inner ring. And during assembly, the shrinkage die is used for shrinking the lintel of the retainer, so that the retainer is restored to the original designed final processing state, and the bearing is ensured to be correctly sleeved. The expansion and contraction process is that the retainer is forced by a mould to be bent and deformed, so that the retainer is difficult to recover to the final processing state of the original design after contraction, and the bending and straightening of the window beam influence the strength of the retainer. Through measurement and verification, the plain line of the slope pressing surface of the retainer after shrinkage is obviously changed from the initial state. The change directly influences the contact state of the roller and the retainer pressing surface, influences the quality indexes of the bearing such as the play, the rotation flexibility and the like, and accordingly greatly shortens the service life of the heavy-duty bearing.

The subsequent installation mode is carried out after the window beam of the retainer is grooved, so that the retainer is prevented from being punched and expanded. The assembled retainer is still maintained in the original design final machining state, so that the traceability of data is convenient to detect, the stability of the bearing clearance is ensured, and the overall quality of the bearing is improved. In the process of slotting the retainer, how to install and fix the retainer so as to be adapted to cutting equipment, and the problem of important consideration is to ensure the adaptability of the perpendicularity and the like of a window beam to be slotted and a cutting knife and the stability of the cutting process.
