Abstract

A kind of bearing equipped with riveter connection retainer, it is made of outer ring, inner ring, roller and retainer, retainer is equipped between inner ring and outer ring, roller is installed on retainer, outer ring is no centre rib structure, and retainer is made of holding stand and retainer lid, and stand is kept to be equipped with riveter, retainer lid is equipped with lubrication groove by riveter with stand riveting, holding stand is kept.The bearing equipped with riveter connection retainer of the utility model, it is simple in structure, it is easy to assembly, longer roller, nest generally applicableization of electric riveting machine are housed, retainer carries lubrication groove, reduce processing technology, improve assembling speed, the load born increases, lubricating condition increases, and the service life is used in the use for improving bearing.

Description

A kind of bearing equipped with riveter connection retainer

Technical field

The utility model is related to technical field of bearings.

Background technology

The retainer bearing parts important as one, its effect are that rolling element is equally spaced, are distributed on raceway Circumference on to prevent work when rolling element between mutually collide and rub.It guides and rolling element is driven to be rolled on correct raceway. The quality of its accuracy of manufacture and quality directly affects the service life of bearing.

Traditional retainer structure is as depicted in figs. 1 and 2, and retainer 5 is pectination type retainer, is commonly used in rolling mill four circle In the structure of column roller bearing FC, FCD, FCDP, outer ring structure as shown in figure 3, be equipped with centre rib 10, assembly when it is usual One dress roller notch of bearing outer ring band, after the row of roller one put in, another row are then entered from notch loading, however, roller Influence in assembling process because of the size of notch, retainer outer diameter to factors such as the inclusion quantities of roller, when assembly sometimes It needs to be made it into the percussion of rubber hammer, so raceway has gouge in assembly, and the copper of indentation, there retainer, which is cut, to fall off In Bearing inner it is difficult to remove, labor intensity also increases, low production efficiency.

Utility model content

In order to solve the above problem existing for traditional bearing retainer and outer ring, the utility model provides a kind of with new The bearing of retainer structure.

The utility model technical solution used for the above purpose is：A kind of axis equipped with riveter connection retainer It holds, is made of outer ring 3, inner ring 4, roller 1 and retainer 2, retainer 2 is equipped between inner ring 4 and outer ring 3, is installed on retainer 2 Roller 1, outer ring 3 are no centre rib structure, and retainer 2 is made of holding stand 6 and retainer lid 9, and stand 6 is kept to be equipped with riveting First 7, retainer lid 9 is riveted by riveter 7 with stand 6 is kept.

The holding stand 6 is equipped with lubrication groove 8.

The bearing equipped with riveter connection retainer of the utility model, the included circle riveter of retainer and lid cooperation riveting, knot Structure is simple, easy to assembly, and longer roller, nest generally applicableization of electric riveting machine are housed, and retainer carries lubrication groove, reduces and adds Work technique, improves assembling speed, and the load born increases, and lubricating condition increases, and the service life is used in the use for improving bearing.

Specific implementation mode

The bearing equipped with riveter connection retainer of the utility model, by outer ring 3,2 structure of inner ring 4, roller 1 and retainer At being equipped with retainer 2 between inner ring 4 and outer ring 3, roller 1 installed on retainer 2, outer ring 3 is no centre rib structure, such as Fig. 9 institutes Show.As shown in figs. 4-7, retainer 2 is made of holding stand 6 and retainer lid 9, and stand 6 is kept to be equipped with riveter 7, retainer Lid 9 is riveted by riveter 7 with stand 6 is kept, and keeps stand 6 to be equipped with lubrication groove 8, integral installation structure is as shown in Figure 8.

The included circle riveter 7 of the bearing retainer of the utility model and the cooperation riveting of retainer lid 9, this structure is because of outer ring 3 reduce a centre rib with traditional outer ring ratio, and such roller can be lengthened in design, then improve the load of bearing；Dress Timing roller does not have to enter from notch loading, decreases outer ring machining gap this procedure, not only saves processing cost Also improve efficiency of assembling；Retainer carries the direct Vehicle Processing of round end, is not necessarily to wire cutting, and processing is simple；Rivet weld nest can when rivet weld Several with specification, it is convenient can to reduce cost riveting again when doing tooling in this way for generalization；Retainer band oil-way, more preferably Improve bearing lubrication condition.

The utility model is described by embodiment, and those skilled in the art know, new not departing from this practicality In the case of the spirit and scope of type, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, at this Under the introduction of utility model, it can modify to these features and embodiment to adapt to particular situation and material without taking off Spirit and scope from the utility model.Therefore, the utility model is not limited to the particular embodiment disclosed, and is owned The embodiment fallen within the scope of claims hereof belongs to the scope of protection of the utility model.
