Abstract
The invention relates to a high-load conical roller bearing. The high-load conical roller bearing comprises an outer ring, an inner ring, a conical roller and a holder. A conical outer roller path for the conical roller to roll is arranged on the peripheral face of the inner ring. A blocking edge is arranged on one side of the conical outer roller path of the inner ring. A flange is arranged on the part, located at one end of the conical roller, of the blocking edge. The holder is provided with a folded edge bent inwards and matched with the flange to fix the holder. The conical roller bearing replaces an inner ring small blocking edge in a traditional roller bearing, and the bearing is machined more conveniently; the phenomena of cracks and chippings of the small blocking edge in the traditional bearing thermal processing and assembling process are avoided; meanwhile, expansion is not needed any more before the holder is assembled, and shrinkage is not needed any more in the assembling process; and compared with the prior art, by means of the conical roller bearing with the structure, the length of the roller can be increased, and the bearing has high bearing capability.
Description
Technical field
The present invention relates to roller bearing technical field, be specifically related to a kind of high loading tapered roller bearing.
Background technique
The rolling element of tapered roller bearing is tapered roller, belongs to separable type bearing, and the cone assembly be made up of roller, retainer and inner ring and cup form (as shown in Figure 1).Single-row tapered roller bearing inner ring has size two ribs, little rib Main Function, for pinning roller and retainer, ensures not being separated of inner ring assembly.The existence on shelves limit no doubt can play the effect of the combination of inner ring assembly, but the interior raceway of bearing can be made to shorten, the confined space of bearing is caused not make full use of, little rib position often has quenching crack to occur, in use often there is block phenomenon, in addition, due to the existence on little shelves limit, inner assembly in an assembling process, need increase the expansion of retainer and assembling contraction process.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, a kind of high loading tapered roller bearing is provided, eliminate the inner-ring small flange in conventional roller bearings, make the processing of bearing convenient, avoid traditional bearing in heat treatment and assembly process, appear at the crackle on little shelves limit and fall block phenomenon, and retainer no longer needs expansion before assembly, no longer shrinks in assembly process, the length of roller can also be increased, make bearing have higher bearing capacity.
The present invention is the deficiency solved the problems of the technologies described above, the technological scheme adopted is: a kind of high loading tapered roller bearing, comprise outer ring, inner ring, tapered roller and retainer, the outer peripheral surface of inner ring has the tapered outer raceways rolled for tapered roller, the side of described inner ring tapered outer raceways is provided with rib, and rib is provided with flange near tapered roller one end, described retainer has and bends inwards and the flange coordinated with flange with fixed retainer.
Further improvement as a kind of high loading of the present invention tapered roller bearing: the inner ring radius of described flange is less than the outer shroud radius of flange, after assembling, the flange of retainer and the flange of inner ring form the mechanism mutually fastened.
Further improvement as a kind of high loading of the present invention tapered roller bearing: described rib is arranged on the large end face of inner ring, the small end face of inner ring is cancelled and arranges rib.
Further improvement as a kind of high loading of the present invention tapered roller bearing: described retainer comprises large end ring, little end ring and connects the horizontal bar of large end ring and little end ring, adjacent two horizontal bars become the tapered pocket hole for placing tapered roller with large end ring and small end collar, flange is arranged on the large end ring of retainer.
beneficial effect
Tapered roller bearing of the present invention, eliminate the inner-ring small flange in conventional roller bearings, make the processing of bearing convenient, avoid traditional bearing in heat treatment and assembly process, appear at the crackle on little shelves limit and fall block phenomenon, and retainer no longer needs expansion before assembly, no longer shrink in assembly process, the tapered roller bearing of this structure can increase the length of roller compared with before, makes bearing have higher bearing capacity.

Fig. 2 is the structural representation of tapered roller bearing of the present invention;
Fig. 3 is the structural representation of tapered roller bearing internal ring of the present invention;
Fig. 4 is the structural representation of tapered roller bearing retainer of the present invention;
Mark in figure: 1, outer ring, 2, inner ring, 3, tapered roller, 4, retainer, 5, flange, 6, large end face, 7, large end ring, 8, little end ring, 9, rib, 10, flange.
Embodiment
As in Figure 2-4: a kind of high loading tapered roller bearing, comprise outer ring 1, inner ring 2, tapered roller 3 and retainer 4, retainer 4 comprises large end ring 7, little end ring 8 and connects the horizontal bar of large end ring 7 and little end ring 8, adjacent two horizontal bars and large end ring 7 and little end ring 8 surround the tapered pocket hole for placing tapered roller 3, and flange 5 is arranged on the large end ring 7 of retainer 4.The outer peripheral surface of inner ring 2 has the tapered outer raceways rolled for tapered roller 3, the side of described inner ring 2 tapered outer raceways is provided with rib 9, rib 9 is arranged on the large end face 6 of inner ring 2, and rib 9 is provided with flange 10 near tapered roller 3 one end, retainer 4 has and bends inwards and the flange 5 coordinated with flange 10 with fixed retainer 4, and the inner ring radius of flange 5 is less than the outer shroud radius of flange 10.After tapered roller bearing assembling, the flange of retainer and the flange of inner ring form the mechanism mutually fastened, and jointly realize the inseparability of inner ring assembly with tapered roller 3, and tapered roller 3 comparatively conventional bearings lengthens, and realize the object improving load.
More than illustrate just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skill in the art understand, when not departing from the spirit and scope that claim limits; many amendments, change or equivalence can be made, but all will fall within protection scope of the present invention.
