Abstract
The utility model relates to a double -row tapered roller bearing for passenger train gearbox, it includes two inner circles on the suit transmission input shaft, the inner ring spacer of setting between the inner circle, the first inward flange of setting on the inner circle lateral wall and second inward flange, the holder of setting between first inward flange and second inward flange, the tapered roller of setting in the holder, the suit sets up the outer lane in the tapered roller outside, the setting is at the outward flange of outer lane lateral wall one side, the setting is in the surpassed distance groove of outward flange root, it is inboard that the setting is located the second inward flange at first inward flange, the utility model discloses compact structure, simple to operate, the rigidity is better, can bear two -way axial load and radial load.
Description
Technical field
This utility model relates to a kind of double-row conical bearing for passenger train gear box.
Background technology
Using single-row tapered roller bearing 32017 in being presently used for passenger train gear box input, be combined into the unit form of the two back-to-back installations of set, a combination thereof structure is limited by part single-width and finished product height thereof；Axiality is poor, and limited by bi-directional axial and radial capacity to base bearing, bending resistance square ability is poor；Countershaft can not be the most bidirectionally limited.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of compact conformation and the double-row conical bearing for passenger train gear box easy for installation.
For solving the problems referred to above, technical solution adopted in the utility model is:
This utility model includes the inner ring on two suit transmission input shaft, the cone spacer being arranged between inner ring, the first inward flange being arranged on inner ring lateral wall and the second inward flange, it is arranged on the retainer between the first inward flange and the second inward flange, the taper roller being arranged in retainer, suit is arranged on the outer ring outside taper roller, it is arranged on the outward flange Y of side, lateral wall, outer ring and is arranged on the grinding undercut of outward flange root, first inward flange is positioned at inside the second inward flange, first inward flange is less than the second inward flange, the endoporus of inner ring and power shaft interference fit, root at the first inward flange and the second inward flange is respectively arranged with grinding undercut.
Inner ring, outer ring and taper roller are GCr15 and Quenching Treatment further.
Use and have the beneficial effects that produced by technique scheme:
This utility model can substitute for the tapered roller bearing unit form assembled back-to-back by two sets 32017, in contrast, this utility model not only compact conformation, easy for installation, rigidity is preferable, it is possible to bearing two-way axial load and radial load (dynamic loading Cr:223KN, dead load Cor:402KN), bearing capacity is bigger, having stronger bending resistance square ability, countershaft have fine bidirectionally limited function；The axially and radially play that this utility model has been adjusted, convenient installation, effectively improve serviceability and the life-span of change speed gear box, by favorable comment and the trust of client.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, outer ring；2, inner ring；3, taper roller；4, cone spacer；5, outward flange；6, endoporus；7, the first inward flange；8, the second inward flange；9, grinding undercut；10, retainer.
Detailed description of the invention
As shown in Figure 1, this utility model includes the inner ring 2 on two suit transmission input shaft, the cone spacer 4 being arranged between inner ring 2, the first inward flange 7 and the second inward flange 8 being arranged on inner ring 2 lateral wall, it is arranged on the retainer 10 between the first inward flange 7 and the second inward flange 8, the taper roller 3 being arranged in retainer 10, suit is arranged on the outer ring 1 outside taper roller 3, it is arranged on the outward flange 5 of side, lateral wall, outer ring 1 and is arranged on the grinding undercut 9 of outward flange 5 root, first inward flange 7 is positioned at inside the second inward flange 8, first inward flange 7 is less than the second inward flange 8, endoporus 6 and the power shaft interference fit of inner ring 2, root at the first inward flange 7 and the second inward flange 8 is respectively arranged with grinding undercut.Processing performance can be improved by grinding undercut.
Further, inner ring 2, outer ring 1 and taper roller 3 are GCr15 and Quenching Treatment.
This utility model can substitute for the tapered roller bearing unit form assembled back-to-back by two sets 32017, in contrast, this utility model not only compact conformation, easy for installation, rigidity is preferable, it is possible to bearing two-way axial load and radial load (dynamic loading Cr:223KN, dead load Cor:402KN), bearing capacity is bigger, having stronger bending resistance square ability, countershaft have fine bidirectionally limited function；The axially and radially play that this utility model has been adjusted, convenient installation, effectively improve serviceability and the life-span of change speed gear box, by favorable comment and the trust of client.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in previous embodiment still can be modified by it, or wherein portion of techniques feature is carried out equivalent；It is combined being apparent to multiple technical schemes of the present utility model as those skilled in the art.And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model embodiment technical scheme.
