A. respectively, are provided with adapter shaft between described separate rotational axes.The utility model can solve goods train severe duty and be produced continuing noise by sharp radius curve, even occurred gnawing the problem of rail, compact conformation, easy to make, is applicable to dissimilar bogie truck.
Description
Technical field
The utility model relates to the improvement of machinery industry Railway wheelset, specifically, relates to and is a kind ofly suitable for the goods train independent wheelset of goods train heavy-duty low-speed by inner curve.
Background technology
Goods train produces continuing noise problem at severe duty by small curve radius rail, be due to the bogie truck of goods train by inner curve time, because outside radius in rail is different, foreign steamer is identical with interior cireular frequency of taking turns, linear velocity is different, under the banks effect of tractive force, bogie truck is run on bend with maximum inclination position, namely bogie truck front-wheel to guide wheel rim recline outer rail run, the right guide wheel rim of the trailing wheel interior rail that reclines runs, the wheel rim making two-wheeled right and tread form the running state of " roll and slide " at the side of Outer Rail and end face, namely continuous print frictional noise is produced.Existing goods train bogie truck is welding frame type bogie, wheel is to being left and right linked wheel, the differential motion of left and right wheel can not be realized, keep two-wheeled to parallel in driving process, 4 orthogonal positions of track adjusting wheel are run, therefore, when maximum inclining position runs, the power applied wheel track is larger, and the noise of generation is also large.
How to overcome the above problems, be then the problem that the utility model faces.
Summary of the invention
The purpose of this utility model is that solving goods train severe duty is produced continuing noise by sharp radius curve, even occurred gnawing the problem of rail, a kind of goods train independent wheelset structure is provided, by the left and right engaged wheel of goods train welding frame type bogie to being replaced by independent wheelset, the noise that effectively can solve train is large, wheel gnawing rail problem.
In order to solve the problems of the technologies described above, the technical solution of the utility model is,
A kind of goods train independent wheelset, comprise left and right two wheels, described left and right two wheels have independently S. A. respectively, are provided with adapter shaft between described separate rotational axes.That is, left wheel has left-handed rotating shaft, and right wheel has dextral shaft, and left and right S. A. is respective independent rotational structure, and is connected by adapter shaft.
Further, described left and right two wheels are connected with respective S. A. interference fit respectively.
Further, the S. A. of described left and right two wheels is measure-alike, and axis is consistent.
Further, described adapter shaft comprises middle cylindrical body and the connecting portion at two ends, and the connecting portion at described two ends is connected with left-right rotary rotating shaft respectively, and arranges swivel bearing in junction.
Further, described connecting portion has groove and engaging lug, and described left rotation and right rotation shaft extension is entered in described groove and is connected with the connecting portion of adapter shaft by described swivel bearing.
Further, the end of described connecting portion also arranges flange, and the engaging lug of described flange and connecting portion is bolted.
Further, between described flange and left-right rotary rotating shaft, felt seal ring is set.
Wherein, described swivel bearing adopts tapered roller bearing.
Further, the forward and backward of described swivel bearing is respectively equipped with forward and backward end ring, and described front bearing back-up ring and left-right rotary rotating shaft are bolted, to give S. A. spacing.
Wherein, described adapter shaft welding fabrication, the cylindrical body namely in the middle of adapter shaft is welded and fixed with the connecting portion at two ends respectively.
The utility model is the engaged wheel commonly used by goods train is left and right independent wheelset to STRUCTURE DECOMPOSITION, left and right separate rotational axes and wheel interference fit integral, Flange joint is passed through with adapter shaft, for ensureing that vehicle wheel rotation is flexible, install swivel bearing additional at the rotary part of left and right separate rotational axes and adapter shaft.
The utility model can solve goods train heavy duty produces noise problem by little curve, is applicable to dissimilar bogie truck.
The utility model compared with prior art has the following advantages and good effect:
1, the utility model can make goods train under heavy-duty low-speed running state, left and right wheels decoupling zero, effectively can prevent left and right wheels " roll and slide ", thus reduces running noises.
2, goods train heavy duty can be solved by little curve, wheel gnawing rail problem.
3, compact conformation, easy to make, be that a kind of goods train shown unique characteristics is taken turns structure, ensure that Heavy-haul Freight train is by nonstandard track.
Accompanying drawing explanation
Fig. 1 is the structure cutaway view of goods train independent wheelset specific embodiment described in the utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Shown in figure 1, in a kind of structure cutaway view of goods train independent wheelset, comprise left wheel 1, left-handed rotating shaft 2, right wheel 3, dextral shaft 4, left wheel 1 is connected with left-handed rotating shaft 2 interference fit, and right wheel 3 is connected with dextral shaft 4 interference fit, and left and right revolute axes configuration is all identical with size, axis is consistent, independently can rotate, be independent of each other.Specifically, adapter shaft 5 is set between left and right S. A., is connected as a single entity by adapter shaft 5.
Adapter shaft 5 comprises middle cylindrical body 51 and the connecting portion 52 at two ends, and cylindrical body 51 adopts solid drawn pipe here, the similar flange arrangement of connecting portion 52 at two ends, and the solid drawn pipe in the middle of adapter shaft is welded and fixed with the connecting portion 52 at two ends respectively.
Connecting portion 52 has groove 521 and engaging lug 522, and left and right S. A. stretches in groove 521, and configures single-row tapered roller bearing 6 on connecting portion 52 and installation surface opposite, left and right S. A. junction, the connection realizing between the two by tapered roller bearing 6.The forward and backward of tapered roller bearing 6 is respectively equipped with front bearing back-up ring 61, rear bearing back-up ring 62, and front bearing back-up ring 61 is connected by bolt 63 with left-right rotary rotating shaft, to give left-right rotary rotating shaft spacing.
