Abstract
The utility model discloses an adapter, which comprises an adapter main body, wherein the adapter main body is provided with an inner arc surface and an outer plane, the outer plane is tangential with a top point of the inner arc surface, three arc grooves are arranged inside the inner arc surface, the widths of the arc grooves on two sides are identical, the width of the intermediate arc groove is greater than that of the arc grooves on two sides, and the adapter is characterized in that an inward concave part is arranged inside the intermediate arc groove, and the top of the inward concave part is of a plane. The adapter is reasonable in structure; and the inward concave part is arranged inside the intermediate arc groove, and the top of the inward concave part is of the plane, so that the uniformity in stress of the adapter and a bearing which is matched with the adapter can be effectively improved, and the service life of the adapter can be prolonged.
Description
Technical field
The utility model relates to a kind of adapter for railway truck.
Background technology
Two bogie side frames are arranged in the freight train bogie truck, bearing saddle assembly is installed respectively in the rear and front end of a bogie side frame, link to each other with the bearing of wheel shaft by bearing saddle assembly, also be that bearing saddle assembly is to borrow the power transmission assembly that connects bogie side frame and bearing in the thing train bogie, the adapter of prior art is with the mode power transmission of lateral deviation line contact, because the contact position is stressed large, adapter and the bearing meeting discontinuity that cooperates with adapter, make local stress too large, unbalance loading, the easy situation such as stuck occur easily, thereby affect the service life of adapter.
Summary of the invention
The purpose of this utility model provides a kind of adapter of rational in infrastructure, long service life.
The technical scheme that realizes the utility model purpose provides a kind of adapter, comprise the adapter body, described adapter body is provided with intrados and outerplanar, the tangent setting in the summit of described outerplanar and intrados, be provided with three arc grooves in the described intrados, the arc groove width on both sides equates that middle arc groove width is greater than the width of the arc groove on both sides, be provided with inner fovea part in the described medial arc groove, the top of described inner fovea part is plane layout.
Further, be provided with dashpot at the arc groove back side on described both sides.
The utlity model has positive effect: of the present utility model rational in infrastructure, in the medial arc groove, be provided with inner fovea part, the top of described inner fovea part is plane layout, and the shaft strength that can the Effective Raise adapter cooperates with it is even, can prolong the service life of adapter.
Description of drawings
For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings, wherein:
Fig. 1 is the structural representation of watching from intrados to outerplanar of the present utility model.
Fig. 2 is the structural representation from watching to the outerplanar intrados of the present utility model.
The specific embodiment
(embodiment 1)
Fig. 1 and Fig. 2 have shown a kind of specific embodiment of the present utility model, and wherein Fig. 1 is the structural representation of watching from intrados to outerplanar of the present utility model.Fig. 2 is the structural representation from watching to the outerplanar intrados of the present utility model.
See Fig. 1 and Fig. 2, a kind of adapter, comprise adapter body 1, adapter body 1 is provided with intrados 2 and outerplanar 3, and the tangent setting in summit of outerplanar 3 and intrados 2 is provided with three arc grooves 4 in the intrados 2, arc groove 4 width on both sides equate, middle arc groove 4 width are provided with inner fovea part 5 greater than the width of the arc groove on both sides in the medial arc groove 4, the top of inner fovea part 5 is that plane 6 arranges.
Arc groove 4 back sides on both sides are provided with dashpot 7.
Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection domain of the present utility model.
