In the utility model, the partition structure between the wearing plate and the transverse retainer is simple; the characteristics of the material and the structure are fully utilized to implement all functions of the traditional carrying saddle, and further the abrasion part of the worn carrying saddle can be only changed and maintained, instead the whole structure is scrapped, and in the meantime, the service life of the wearing plate can be prolonged to the maximum extent.
Description
Technical field
The utility model belongs to rolling stock design and manufacturing technology field, especially belongs to railway goods train bogie design and manufactures, the particularly split type adapter of railway goods train bogie.
Background technology
Tradition " three-major-items " formula railway goods train bogie adopts without axle box tapered roller bearing structure, and the draw bail of wheel shaft and bogie side frame generally adopts adapter structure.For ease of vehicle, smoothly by curve, adapter and side frame guide laterally and are longitudinally all leaving certain gap.When vehicle operating, this gap can change, and especially when by curve, this gap variable quantity changes with radius of curve, adapter vertical, horizontal gear is come in contact with bogie side frame, and then produce abrasion, and especially laterally abrasion are particularly serious.Traditional adapter adopts integral structure, transverse gear directly wears away with bogie side frame, in utilization process, carry out repair welding bogie side frame and adapter according to the abrasion loss of adapter and bogie side frame again, both increased the maintenance capacity of bogie side frame, adapter, simultaneously because bogie side frame, adapter are important carrying steel casting, directly can exert an adverse impact to the reliability of part carrying out repair welding, further adapter belongs to middle-size and small-size smart mold casting workpiece, impact on other fit dimensions after repair welding is larger, thereby often after rib wears away limit, directly scraps and cause larger waste.Thereby in railway goods train bogie, necessary employing one can guarantee traditional adapter all functions, can make again only to change after adapter abrasion, repair abrasion position and new bearer saddle structure that unlikely whole mechanism scraps.
Summary of the invention
The utility model discloses the split type adapter of a kind of railway goods train bogie according to the deficiencies in the prior art.Problem to be solved in the utility model is to provide one can guarantee traditional adapter all functions, can make again only to change after adapter abrasion, repair abrasion position and new bearer saddle structure that unlikely whole mechanism scraps.
The utility model is achieved through the following technical solutions:
The split type adapter of railway goods train bogie, described adapter is arranged in side frame guide, comprises top, saddle, longitudinally gear and transverse gear, it is characterized in that: described transverse gear has by round pin and is connected detouchable wearing plate with bogie side frame fitting surface.
Described transverse gear coordinates direction middle part to have located lateral groove with bogie side frame, along the vertical transverse gear round pin that arranges, through hole is installed; Wearing plate is "T"-shaped structure, and the pin of "T"-shaped structure is provided with wearing plate round pin through hole is installed; The "T"-shaped pin of wearing plate is embedded and is fixed in positioning groove by round pin.
Described wearing plate is high molecular abrasion-proof nylon material.
The utility model adapter is machine up moulding after overall smart mold casting, and its top, saddle and longitudinal gear are still conventional confguration, and rubber pad attachment face is arranged at top, and saddle is bearing fit face, and longitudinally gear is for limiting the longitudinal travel of bogie side frame and adapter; Adapter is expanded letter formula structure, and adapter is arranged on after bogie truck, and side frame guide gear drops on adapter two transverse gear inner sides; Adapter transverse gear adopts middle part to offer positioning groove, uses and is fixedly connected with wearing plate along the vertical transverse gear round pin installation through hole of offering; Coordinating wearing plate with transverse gear is "T"-shaped integral structure, and its driving surface middle part rear side is location and installation pin, and installation foot is provided with wearing plate round pin through hole is installed; When installation, "T"-shaped installation foot embeds in the positioning groove of transverse gear, by round pin, wearing plate is fixed on to adapter.Round pin is by flat gasket and spring cotter locking.
Compared with prior art the utlity model has following beneficial effect:
1, adapter and bogie side frame side friction face adopt Split type structure, only have wearing plate wearing and tearing in utilization process, and abrasion only need change wearing plate and needn't overhaul or scrap adapter after limit, can extend adapter service life, raising bogie truck economy.
2, wearing plate adopts high molecular abrasion-proof nylon material, both there is higher resistance to abrasion, contact abrasion during with bogie side frame transverse gear, friction coefficient between high molecular abrasion-proof nylon non-metallic material and bogie side frame transverse gear metallic material friction pair can more formerly all adopt the friction coefficient between metallic material significantly to reduce, friction force between friction pair is reduced and reduce the abrasion of material, simultaneously, because bogie side frame metallic material is larger than the hardness of wearing plate high molecular abrasion-proof non-metallic material, therefore, when bogie side frame transverse gear and the contact friction of adapter wearing plate, thereby the preferential abrasion of non-metallic material reduce bogie side frame abrasion, reduce the maintenance capacity of bogie side frame, improve bogie side frame serviceability.
3, wearing plate adopts T-shaped structure directly to embed and be contained in the special structure of adapter, and fix by round pin structure, the T-shaped structure of wearing plate coordinates with the positioning groove of transverse gear middle part horizontally set, its abrasion are stressed more excellent, mounting structure is more stable, can further extend wearing plate service life, is convenient to install, change simultaneously, especially be convenient to directly dismantle on the line, change, improved the maintainability of bogie truck.
The utility model wearing plate and transverse gear partition are simple for structure, make full use of the characteristic of material and structure, realize and can guarantee traditional adapter all functions, can make again only to change after adapter abrasion, repair abrasion position and new bearer saddle structure that unlikely whole mechanism scraps, extend most possibly the service life of wearing plate simultaneously.
