Abstract
The utility model relates to a tapered roller bearing, in particular to a tapered roller bearing with an inner ring rib, aiming at solving the technical problems that the existing tapered roller bearing is worse in quality since an inner ring in the bearing is a common rib and a tapered roller is easy to get out of the inner ring when the tapered roller is used; the assembled tapered roller bearing is also worse in quality since the tapered roller bearing is more complex to assemble because a plurality of small end faces of retainers in the tapered roller bearings are in parallel with the end face of an outer ring and the like. The tapered roller bearing comprises an inner ring (1) and an outer ring (2), wherein a retainer (3) is arranged between the inner ring and the outer ring, and a row of tapered rollers (4) are arranged on the retainer. The tapered roller bearing is characterized in that one end of the inner ring (1) is provided with a large rib (5), the large rib is arranged at the outer end of each tapered roller, and the large rib is step-shaped.
Description
Technical field
The utility model relates to a kind of roller bearing, especially relates to a kind of tapered roller bearing of interior astragal rib.
Background technique
Automobile has generally comprised inner ring, outer ring with bearing, is fixed with single-row by retainer or the biserial roller between the Internal and external cycle.Chinese patent discloses a kind of sealing double-row conical bearing (notice of authorization number: CN 2625638Y) of new structure, it comprises an outer ring with double raceway, two single raceway inner rings, two retainers, a cone spacer between two row rollers and inner ring, the external diameter of outer ring are " V " font, each adaptively has a skeleton in the exterior edge face of two retainers, the all suitable seal ring that is combined with on each skeleton, the sectional shape of skeleton, seal ring is like channel-section steel, and the material of seal ring is a rubber.Chinese patent also discloses a kind of double-row conical bearing (notice of authorization number: CN 2864213Y) of two sides band dust-proof cover, it is made up of outer ring, inner ring, tapered roller, retainer and spacer ring, the bearing outer ring both ends of the surface have dust-proof cover, and the outer ring is directly as the working surface that supports.But the inner ring in these two kinds of bearings is common rib, tapered roller in use, from inner ring, deviate from easily, so inferior quality of product, and the retainer small end face that adopts in this class tapered roller bearing all flushes with cycle surface, cause the product assembling comparatively complicated, can cause the inferior quality of assembling back product equally.
The model utility content
The utility model provides a kind of tapered roller bearing of interior astragal rib, it mainly is that the inner ring that solves in the existing in prior technology bearing is common rib, tapered roller in use, from inner ring, deviate from easily, so inferior quality of product, and the retainer small end face that adopts in this class tapered roller bearing all flushes with cycle surface, causes product assembling comparatively complicated, can cause the technical problem of the inferior quality etc. of assembling back product equally.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The tapered roller bearing of a kind of interior astragal rib of the present utility model comprises inner ring and outer ring, is provided with retainer between inner ring and the outer ring, retainer is provided with a row tapered roller, one end of described inner ring is provided with large-flange, and large-flange is located at the tapered roller outer end, and large-flange is a ladder-type.The large-flange of ladder-type is set at the large end face place of inner ring, not only helps the rolling of tapered roller, and can prevent that tapered roller from deviating from from inner ring, improve the quality of product.The outer surface of inner ring and the internal surface of outer ring all are provided with the conical surface, and the angle of the conical surface is consistent with the angle of tapered roller outer surface, are convenient to tapered roller and roll.The inside of inner ring is provided with through hole, can be used for the cross-under flange plate.
As preferably, described large-flange has an inclined-plane of being close to the tapered roller large end face, and the upper end on inclined-plane connects vertically disposed step.The internal surface of step does not contact the tapered roller large end face, can prevent the tapered roller that weares and teares like this.
As preferably, have the appearance indent on the inner ring at described tapered roller two ends.Hold in the indent to be marked with grease, can at any time lubricant oil be injected between tapered roller and the inner ring, reduce the wearing and tearing of tapered roller, increase the service life.Hold indent simultaneously and can prevent that also dust from entering between tapered roller and the inner ring, further increase the service life.
As preferably, the small end face of described retainer is lower than the plane, outer ring.The small end face of retainer is lower than the plane, outer ring, and promptly the small end face of retainer is outwards given prominence to the plane of outer ring, helps the assembling of product, and improves the quality of product.
Therefore, the utility model is provided with the large-flange of ladder-type at the outer end of inner ring end face, can prevent that like this tapered roller from deviating from, improve the quality of product, and be arranged to be lower than the plane, outer ring at the small end face of retainer, help the assembling of product like this, simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering among the figure: inner ring 1, outer ring 2, retainer 3, tapered roller 4, large-flange 5, appearance indent 6.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the tapered roller bearing of a kind of interior astragal rib of this example, as Fig. 1, inner ring 1 and outer ring 2 are arranged, be provided with retainer 3 between inner ring and the outer ring, retainer is provided with a row tapered roller 4, and the small end face of retainer is lower than the plane, outer ring.Have on the inner ring 1 at tapered roller two ends and hold indent 6.One end of inner ring is provided with large-flange 5, and large-flange is located at the tapered roller outer end, and large-flange is ladder-type, and promptly large-flange has an inclined-plane of being close to tapered roller 4 large end faces, and the upper end on inclined-plane connects vertically disposed step.
During use, on flange plate or bearing support, inner ring is fixed, can be made into employed tapered roller bearing unit on the automobile by the crimping of snap ring, nut or flange plate in the cross-under of the inside of inner ring 1.
The above only is a specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
