Description

Wheel rim lubricating device

Technical Field

The utility model belongs to the technical field of rail vehicle makes, specifically be a rim lubricating arrangement.

Background

When the train runs to a small curve section, the rim of the guide wheel at the outer rail side is in contact with the rail track pitch angle/track pitch surface, and the contact pressure is large and accompanied by impact, and meanwhile, the sliding velocity component in the contact spot is large, so that the serious abrasion of the wheel track is caused, the running resistance of the train is increased, and the problems of noise pollution and the like are caused. Along with the development of railway transportation towards high speed and heavy load, the contact condition of the wheel rail is further worsened, and the problem of wheel rail abrasion is more and more serious, so that a large number of steel rails and wheel pairs are scrapped in advance, the energy consumption of train operation is increased, and even the vehicles are derailed.

In order to reduce wheel-rail wear, a currently common measure is wheel-rim lubrication. The wheel flange lubrication is that proper lubricant is applied to the wheel edge of the wheel by a strict control method, and dry sliding friction with high friction coefficient is changed into lubricated sliding friction with low friction coefficient, so that the wheel rail abrasion and train operation energy consumption are reduced, the turning wheel and rail changing period is prolonged, and the train operation safety is improved.

The common structure of dry lubrication is to mount a wheel rim lubricator on a bogie frame, mount a carbon lubricating block and a constant force spring in the lubricator, the carbon lubricating block contacts with the wheel rim under the action of the constant force spring and transfers a lubricating medium to the wheel rim to realize the purpose of lubrication, the constant force spring is mounted on a guide rail, and the guide rail is mounted on a carbon brush box, as shown in fig. 1, the mounting structure of the existing guide rail and carbon brush box is that a nut 3 is fixed on an L-shaped part 101 at the tail end of the guide rail 1, and the bolt penetrates through the side wall of the carbon brush box and the nut 3 to fix the guide rail on the carbon brush box.

Disclosure of Invention

To the problem that exists among the above-mentioned prior art, the utility model provides a simple structure, convenient to use's rim lubricating arrangement.

The utility model provides a wheel rim lubricating arrangement, including the carbon brush box that is used for installing the carbon block, the carbon brush box front and back end all has the opening, is equipped with the carbon block guide rail in the carbon brush box, and carbon block guide rail tail end is L shapes, and carbon block guide rail curb plate is equipped with the constant force spring that is used for pushing away the carbon block, carbon brush box rear end bottom plate has the recess, carbon block guide rail L shape tail end is equipped with inside first kink, first kink front side is in the recess, and the rear side department that lies in the kink of carbon block guide rail L shape tail end on the both sides wall of carbon brush box rear end is equipped with the trompil, and trompil department pegs graft and has the guide rail round pin, and guide rail round pin one side is opened there is the pinhole, and pinhole department is connected with.

Further, the bolt is an R pin.

Furthermore, the tail end of the carbon slide block guide rail is also provided with a forward second bending part.

The utility model discloses a rim lubricating arrangement, guide pin and the cooperation of lubricant block guide rail, through R round pin fixed position, when needing to change dress lubricant block, only need pull open the R round pin, take out the guide pin, take out the lubricant block guide rail, the carbon lubricant block of packing into, the lubricant block guide rail of impressing again inserts the guide pin again, and the card is gone into the R round pin and can be accomplished the operation of changing the carbon slider, simple structure, convenient to use.
