Abstract

The utility model relates to a novel double-retainer-ring combined cage for cylindrical roller bearings, which consists of a retainer ring A (1), a retainer ring B (2), upright posts (3), rivets (4),equidistributed holes (5) and oil grooves (6). The cage has the following characteristics that: each part is of a separate structure and can be separately assembled, both the retainer ring A (1) and the retainer ring B (2) are provided with the equidistributed holes (5), the upright posts (3) are arranged between the retainer ring A (1) and the retainer ring B (2), the upper and the lower ends ofthe upright posts (3) are provided with the rivets (4) which are inserted into the equidistributed holes (5) to connect the retainer ring A (1) and the retainer ring B (2) together, and both curved sides of each upright post (3) are provided with the oil grooves (6). The utility model has the following advantages that: compared with the prior art, the cage solves the defects of the low wear resistance and inconvenient use of the product by adopting iron material and the separate structures, and moreover, the material selection is convenient, the cost is low, and the popularization is easy.

Description

Novel roller bearing double block ring combination retainer

Technical field

The utility model relates to a kind of bearing part, specifically a kind of novel roller bearing double block ring combination retainer.

Background technique

At present, retainer of the prior art is an integral structure, and material is copper, and shortcoming is not wear-resisting, use inconvenience, and cost is bigger, the waste resource.

Summary of the invention

The purpose of this utility model is to provide a kind of retainer of split-type structural, the novel roller bearing double block ring combination retainer that each parts can independent partial installation.

The technological scheme that its technical problem that solves the utility model adopts is: it comprises back-up ring A (1), back-up ring B (2), column (3), fourth of the twelve Earthly Branches head (4), halving hole (5), oil groove (6), it is characterized in that being between each parts split-type structural, can independently assemble, be provided with halving hole (5) on back-up ring A (1) and the back-up ring B (2), be provided with column (3) between back-up ring A (1) and the back-up ring B (2), column (3) two ends up and down is provided with fourth of the twelve Earthly Branches head (4), fourth of the twelve Earthly Branches head (4) connects back-up ring A (1) and back-up ring B (2) by inserting halving hole (5), the both sides cambered surface of column (3) is provided with oil groove (6), oil groove (6) can be deposited less amount of lubrication oil, in use, this novel roller bearing double block ring combination retainer can lubricating bearings, thereby solves in the product using process not wear-resisting, the shortcoming that life-span is short.

The beneficial effects of the utility model are, the utility model is compared with prior art, and this novel roller bearing double block ring combination retainer adopts ferrous material and split-type structural to solve the shortcoming that product is not wear-resisting, use is inconvenient, and draws materials conveniently, cost is lower, is beneficial to popularization.
