Abstract
The utility model relates to the field of machinary, a cylindrical roller bearing for on locomotive especially. It includes outer lane, inner circle, roller, keeps frame foundation and holder lid, inner circle terminal surface height be greater than outer lane terminal surface height, frame foundation and the holder lid that keeps adopt bronze ZCuAL10Fe3Mn2 to make, a rivet is cylindrical for installing the roller. Produced axial displacement when this bearing can adapt to the locomotive turn has the wearability, and impact toughness has better intensity, and has simplified technology, has improved efficiency.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of roller bearing on locomotive.
Background technique
Roller bearing on locomotive, as shown in Figure 1, has the feature of general roller bearing, and existing higher radial bearing capacity, is also applicable to higher rotating speed, the feature that inside and outside circle can be installed respectively; But must require structurally for railway transport, some particular/special requirement of aspect such as play, retainer, thus ensure safety reliability; And because be ceaselessly operate, consume also very fast, fabricating cost is also higher.
Model utility content
The purpose of this utility model is to provide a kind of roller bearing on locomotive.
The purpose of this utility model is achieved through the following channels: a kind of roller bearing on locomotive, and it comprises outer ring, inner ring, roller, maintenance stand and retainer lid, and described inner ring face height is greater than cycle surface height; Described maintenance stand and retainer lid adopt bronze ZCuAL
10fe
3mn
2make; Be cylindrical for installing the rivet of roller.
A kind of roller bearing on locomotive of the utility model, improves in the following aspects:
One is that the structural design of bearing adopts reinforced E structure, and compared with prior art as shown in Figure 1, cylindrical roller used increases, and can carry larger dynamic load and dead load; Inner ring height is greater than the structural design of cycle surface height, and what produce when can adapt to locomotive turning moves axially;
Two is that Bearing fittings retainer material adopts bronze ZCuAL
10fe
3mn
2, have more wear resistance, impact toughness than HPb59-1 brass retainer originally used, there is better intensity;
Three is that the rivet of riveted uses columniform rivet to substitute the rivet of cup head, only need adopt hydraulic cold riveter just can a riveted, does not need the riveted resembling snap rivet, must heat separately one by one and press separately, thus simplify technique, improve efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is roller bearing structural representation in prior art;
Fig. 2 is the utility model structural representation;
In figure, 01: outer ring, 02: inner ring, 04: roller, 06: keep stand, 16: retainer lid, 09: rivet.
Embodiment
As shown in Figure 2, a kind of roller bearing on locomotive of the utility model, it comprises outer ring 01, inner ring 02, roller 04, keeps stand 06 and retainer lid 16, it is characterized in that: described inner ring 02 face height is greater than outer ring 01 face height; Described maintenance stand 06 and retainer lid 16 adopt bronze ZCuAL
10fe
3mn
2make; For installing the rivet 09 of roller 04 for cylindrical.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change can expected without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
