Abstract
The utility model relates to a tapered roller bearing filled up with rollers, which comprises a bearing inner ring, a bearing outer ring and tapered rollers. The utility model is characterized in that: a salient stage arranged on a small retaining edge of the bearing inner ring is opposite to the small end faces of the tapered rollers arranged between the bearing inner ring and the bearing outer ring, a concave surface is arranged on the big end face of each tapered roller, the concave surfaces abut against limiting pieces on a big retaining edge of the bearing inner ring, and a row of tapered rollers between the bearing inner ring and the bearing outer ring are tangent. The utility model has the advantages of greatly improving the rated burden of the bearing, consequently increasing the load carrying capacity of the bearing, enlarging the space between the rollers for storing grease, accordingly facilitating the lubrication of the bearing, and in this way increasing the load carrying capacity of the bearing while improving the lubrication of the bearing.
Description
Technical field
The utility model relates to a kind of roller bearing, particularly a kind of tapered roller bearing of completely adorning roller.
Background technique
Traditional single-row tapered roller bearing structure is formed (see figure 1) by outer ring, inner ring, roller, retainer at present, retainer plays guiding and isolates the effect of roller, owing to will guarantee the strength and stiffness of retainer, the deck-siding of retainer will be by enough sizes, the beam of these retainers is distributed between the roller, thereby the space that has taken circumference is restricted the increase of roller quantity, thereby define the increase of the rated load of bearing, along with the load that the industrial development bearing requires to bear is more increased, traditional conical bearing structure is restricted.
Summary of the invention
The purpose of this utility model is to remove traditional retainer in the prior art the single-row tapered roller bearing structure, has vacateed more space on interior raceway, thereby can increase the quantity of roller, and then can improve the bearing capacity of bearing.A kind of tapered roller bearing of completely adorning roller of the utility model design, comprise bearing inner race, bearing outer ring, tapered roller, it is characterized in that: on the little rib of bearing inner race, have an outstanding step relative with the small end face of tapered roller between bearing inner race and bearing outer ring, on the large end face of tapered roller, inner concave is arranged, margining tablet on the large-flange of inner concave and bearing inner race is inconsistent, and the row tapered roller between bearing inner race and bearing outer ring is tangent mutually.The utility model has the advantages that the rated load that can significantly improve bearing, thereby increase bearing load carrying capacity, the space of the storage grease between the roller increases, and can help the lubricated of bearing more, can improve the lubricated of bearing like this when increasing the bearing ability to bear.
Description of drawings
Fig. 1 is the single-row tapered roller bearing structural representation of prior art,
Fig. 2 is a structural representation of completely adorning the tapered roller bearing of roller of the present utility model,
Fig. 3 is the A portion enlarged diagram of Fig. 2 of the present utility model,
Below in conjunction with accompanying drawing to the detailed description of the invention:
Specific implementation method
Comprise bearing inner race 1, bearing outer ring 2, tapered roller 3 among Fig. 2,3, it is characterized in that: having an outstanding step 5 relative on the little rib 4 of bearing inner race 1 with the small end face 6 of tapered roller 3 between bearing inner race 1 and bearing outer ring 2, on the large end face 7 of tapered roller 3, inner concave 8 is arranged, margining tablet 10 on the large-flange 9 of inner concave 8 and bearing inner race 1 is inconsistent, and the row tapered roller 3 between bearing inner race 1 and bearing outer ring 2 is tangent mutually.
The tapered roller bearing of completely adorning roller of the present utility model is compared with Fig. 1 bearing among Fig. 2,3, saved original retainer, can increase the quantity of tapered roller 3, generally can increase by 1 to 3 tapered roller 3, tapered roller 3 can fill up the circumference of raceway, in order to guarantee that tapered roller 3 does not come off from interior raceway position, the inconsistent of inner concave 8 arranged installing on the external diameter on the big shelves limit 9 of bearing inner race 1 on the large end face 7 of a margining tablet 10 and tapered roller 3, guarantee that tapered roller 3 and bearing inner race 1 form a whole, and can rotate stably.
The bearing of this structure has overcome original retainer and has taken up room, thereby make tapered roller can be covered with the interior raceway of tapered roller bearing, thereby can increase the rated load of bearing, can make unidimensional bearing can bear bigger load, owing to removed retainer, increase the storage area of bearing grease, the working life of improving the lubricated raising bearing of bearing simultaneously, this bearing is fit to heavily loaded use occasion, especially heavy-duty car wheel hub occasion more.
