Abstract
The utility model relates to a holder of cylindrical roller bearing, including keeping the frame foundation and setting up the holder lid on keeping the frame foundation terminal surface, keep frame foundation and holder lid to adopt closing -up fixed, and keep on the terminal surface of frame foundation the wide outward flange of depended wheel even set up with the rivet hole of closing -up, evenly set up a plurality of roller caulking groove on keeping the frame foundation, and set up a rivet hole between adjacent roller caulking groove. The utility model provides a big problem of the present cylindrical roller bearing retainer rivet hole site processing degree of difficulty, improved bearing retainer riveting intensity simultaneously, pressure to keeping the ware when having reduced the riveting has improved bearing riveting speed and bearing life -span.
Description
Technical field
The utility model relates to retainer technical field, particularly relates to a kind of retainer of roller bearing.
Background technique
The retainer of roller bearing is made up of the maintenance stand of copper body and retainer lid two-part, stand and retainer lid is wherein kept to adopt rivet interlacement, play the effect of separation and pilot bearing roller, the riveted mode of existing frivolous serial cylinder roller bearing retainer seat and retainer lid is for knocking riveted, it is long that the riveted time is knocked in craft, efficiency is low, and the rivet hole position difficulty of processing of existing maintenance stand and retainer lid is large, error is large, easy generation retainer distortion and there is the problem of riveted insufficient strength, affects bearing working life.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of retainer of roller bearing, solve the problem that existing cylinder roller bearing retainer rivet hole position difficulty of processing is large, improve retainer riveted intensity simultaneously, pressure to retainer when decreasing riveted, improves bearing riveted speed and bearing life.
The utility model is achieved through the following technical solutions: a kind of retainer of roller bearing, comprise and keep stand and be arranged on the retainer lid kept on stand end face, described maintenance stand and retainer lid adopt closing-up to fix, and keep the wide outward edge of roller on the end face of stand that the rivet hole with closing-up is evenly set, described maintenance stand is evenly arranged several roller caulking grooves, and a rivet hole is set between adjacent roller caulking groove.
Further, described rivet hole is arranged about keeping the Central Symmetry of stand, and rivet hole is equal to the distance of adjacent roller caulking groove.
Further, on the end face of described retainer lid, the wide outward edge of roller evenly arranges the butt riveted joint hole of docking with rivet hole.
Compared with prior art, the beneficial effects of the utility model are: the utility model passes through the rivet hole optimal design on the maintenance stand of retainer, to originally be arranged on the rivet hole kept on stand end face neutral position, change and be located at the wide outer peripheral position of the roller keeping stand end face, and keep rivet hole equal to the distance of adjacent roller caulking groove, position, the hole processing space solved in the past because of rivet hole is little, the problem that difficulty of processing is large, and improve work efficiency, rivet hole is by retainer edge placement simultaneously, improve retainer Integral riveting intensity, pressure to retainer when decreasing riveted, improve bearing riveted speed and bearing life.

Fig. 4 is the retainer lid side cutaway view of the utility model cylinder roller bearing retainer.
Wherein: 1, keep stand; 2, roller caulking groove; 3, rivet hole; 4, retainer lid; 5, butt riveted joint hole.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-4, the utility model relates to a kind of retainer of roller bearing, comprise and keep stand 1 and be arranged on the retainer lid 4 kept on stand 1 end face, described maintenance stand 1 and retainer lid 4 adopt closing-up to fix, and keep the wide outward edge of roller on the end face of stand 1 that the rivet hole 3 with closing-up is evenly set, described maintenance stand 1 is evenly arranged several roller caulking grooves 2, and a rivet hole 3 is set between adjacent roller caulking groove 2, described rivet hole 3 is arranged about keeping the Central Symmetry of stand 1, and rivet hole 3 is equal to the distance of adjacent roller caulking groove 2, on the end face of described retainer lid 4, the wide outward edge of roller evenly arranges the butt riveted joint hole 5 of docking with rivet hole 3.
In sum, the utility model easily produces retainer distortion and riveted insufficient strength for existing during existing frivolous serial cylinder roller bearing retainer riveted assembling, affect the problem in bearing working life, the maintenance stand 1 that cylinder roller bearing retainer riveted is fixed and the rivet hole optimal design of retainer lid 4.
The rivet hole 3 being originally positioned at end face neutral position on stand 1 will be kept, change and be located at the wide outer peripheral position of the roller keeping stand end face, and keep rivet hole equal to the distance of adjacent roller caulking groove, the change of position, hole is carried out to rivet hole 3, position, the hole processing space solved in the past because of rivet hole is little, the problem that difficulty of processing is large, and improve work efficiency, and combine employing rivet heat distortion mode riveted, rivet hole 3 is by retainer edge placement simultaneously, improve retainer Integral riveting intensity, pressure to retainer when decreasing riveted, improve bearing riveted speed and bearing life.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
