Abstract

The utility model relates to a cylindrical roller bearing, in particular to a novel double row cylindrical roller bearing, which comprises outer rings (4), an inner ring (3), a cylindrical roller (2) and retainers; the novel double row cylindrical roller bearing is characterized in that: the outer rings (4) and the retainers are two independent sets; and the width of each outer ring (4) is one half of that of the inner ring (3). The novel double row cylindrical roller bearing has the advantages that: (1) the novel double row cylindrical roller bearing adopts two outer rings and one inner ring; the design is adopted to fully change the conventional condition that the whole set of bearing is scrapped as long as one raceway of the double-raceway outer ring of the bearing is damaged; and at present, the bearing can also be used as long as one damaged outer ring is replaced; and (2) the novel double row cylindrical roller bearing adopts electric riveting pillar retainers which have the advantages of simple structure, easy machining, light mass, small volume and the like and can save a part of space, and the number of rollers can be increased, so the rated load of the bearing is increased and further the service life of the bearing is greatly prolonged.

Description

Novel Biserial cylindrical roller bearing

Technical field

The utility model relates to roller bearing, especially novel Biserial cylindrical roller bearing.

Background technique

Normally used Biserial cylindrical roller bearing is made up of an outer ring with double raceway and an inner ring, adopts solid cage, this bearing structure is simple, have advantages such as easy for installation, flexible operation, effect is very good as carrying evenly then in using process, but it also has the shortcoming of self as follows:

(1), under some special working conditions, bearing in use has in the outer ring with double raceway row stressed bigger, another is listed as intact situation so occur in the bearing two raceway outer rings that a row raceway damages, so cause a whole set of bearing to scrap;

(2), also have this structure Biserial cylindrical roller bearing can only adopt solid cage owing to will guarantee that retainer has certain intensity,, and then limited the rated load of this airframe bearing so the roller number of bearing can not be too many.

The model utility content

The purpose of this utility model provides a kind of novel Biserial cylindrical roller bearing, thereby it can keep in repair the saving cost by changing the outer ring after bearing outer ring ball track damages, improved the bearing capacity of bearing simultaneously.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of novel Biserial cylindrical roller bearing comprises outer ring, inner ring, cylindrical roller and retainer, and its specialization is that wherein outer ring and retainer are independently two covers, and the width of each outer ring is inner ring half.

Wherein retainer adopts the rivet weld post cage.

Wherein the retainer packing ring all is installed in every suit retainer both sides.

The beneficial effects of the utility model are as follows:

(1) bearing of the present utility model adopts two outer rings and an inner ring, adopt this design, changed fully in the past as long as the bearing outer ring with double raceway has a row raceway to damage, the final result that then a whole set of bearing is scrapped, as long as now a bad outer ring is changed, bearing can also use, and makes significantly improve the working life of bearing;

(2) adopt the rivet weld post cage, advantage such as that this retainer has is simple in structure, easy processing, light weight, volume are little, and can save a part of space, can increase the roller number, thereby make the rated load of bearing increase to some extent, and then make significantly improve the working life of bearing.

Accompanying drawing 2 is a structural representation of the present utility model.

Embodiment

Come the utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 2, the utility model bearing comprises outer ring (4), inner ring (3), cylindrical roller (2) and retainer, and wherein outer ring (4) and retainer are independently two covers, and the width of each outer ring (4) is inner ring (3) half.

Wherein retainer adopts the rivet weld post cage, and in every suit retainer both sides retainer packing ring (1) is installed all.

Claims
