Abstract
The utility model relates to a railway freight car is with two effect elasticity side bearing roll bearing structure, it includes side bearing seat, roller axle and roller, the roller rotates and supports the roller is epaxial, its characterized in that: the both ends of roller axle are square column shape structure, the cooperation of square column shape structure sets up is seting up in the square groove on the side bearing seat. The utility model discloses because adopt the middle section be cylindrical structure, both ends for the roller axle of square column shape structure, the roller rotates to be connected cylindrical structural, and the cooperation of the square column of roller axle shape structure sets up in the square groove of side bearing seat, consequently, the emergence rotation under can not the drive at the roller under the restraint in the square groove of side bearing seat of roller axle.
Description
Technical field
The utility model relates to a kind of railway truck double-acting elastic side bearing rolling supporting structure, belongs to rolling stock technical field.
Background technology
The side bearing of current railway goods train bogie mostly is double-acting elastic side bearing, and the roller of side bearing adopts sliding bearing structure.Due to roller, operationally pressure is larger; in addition often can get rusty in plain bearing inside; cause Roller Shaft usually together can rotate with roller; and after Roller Shaft rolls; the height of roller can be caused to change (because the Support Position of roller is for eccentric), thus cause curve passing through to pass through hydraulic performance decline.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of railway truck double-acting elastic side bearing rolling supporting structure, and this supporting construction can solve the problem that Roller Shaft and roller rotate simultaneously effectively.
For achieving the above object, the utility model is by the following technical solutions: a kind of railway truck double-acting elastic side bearing rolling supporting structure, it comprises side bearing, Roller Shaft and roller, described roller is rotatably supported in described Roller Shaft, it is characterized in that: the two ends of described Roller Shaft are square column type structure, and described square column type respective outer side edges is arranged in the square groove be opened on described side bearing.
The stage casing of described Roller Shaft is cylindrical structural, and described roller is rotatably connected on the cylindrical structural of described Roller Shaft.
Described in each, the end face of square column type structure is arcwall face.
The fitting surface of described Roller Shaft and described roller scribbles dry lubrication material.
Described dry lubrication material is molybdenum disulphide.
The utility model is owing to taking above technical scheme, it has the following advantages: 1, the utility model Roller Shaft that stage casing is cylindrical structural owing to adopting, two ends are square column type structure, roller is rotatably connected on cylindrical structural, and the square column type respective outer side edges of Roller Shaft is arranged in the square groove of side bearing, therefore, Roller Shaft can not rotate under the constraint of side bearing square groove under the drive of roller.2, the utility model owing to scribbling dry lubrication material on the fitting surface of Roller Shaft and roller, therefore both can reduce the friction force between Roller Shaft and roller, also can prevent fitting surface from getting rusty.3, the end face of steering column is arranged to arcwall face by the utility model, and it can play the effect being convenient to identify in fitting process, thus prevents from installing by mistake.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present utility model;
Fig. 2 be the utility model roller with Roller Shaft coordinate schematic diagram;
Fig. 3 is the schematic side view of Fig. 2.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figures 1 to 3, the utility model proposes a kind of railway truck double-acting elastic side bearing rolling supporting structure, it comprises side bearing 1, Roller Shaft 2 and roller 3, and wherein, roller 3 is rotatably supported in Roller Shaft 2.The stage casing of Roller Shaft 2 adopts cylindrical structural, on the cylindrical structural that roller 3 is rotatably connected on Roller Shaft 2 and with the center of circle of cylindrical structural for center of turn.The two ends of Roller Shaft 2 adopt square column type structure, and square column type respective outer side edges is arranged in the square groove be opened on side bearing 1.Define coordinating between square groove with steering column structure the constraint in Roller Shaft 2 rotation direction, thus ensure that Roller Shaft 2 can not be rotated with roller 3.
Further, the end face being positioned at the steering column at Roller Shaft 2 two ends is arranged to arcwall face, can play the effect being convenient to identify like this in fitting process, to prevent from installing by mistake.
Further, Roller Shaft 2 with the fitting surface of roller 3 scribble dry lubrication material, both can reduce the friction force between Roller Shaft 2 and roller 3, also can prevent fitting surface from getting rusty.Particularly, dry lubrication material can adopt molybdenum disulphide.
The utility model is only described with above-described embodiment, and the structure of each parts, setting position and connection thereof all can change to some extent.On the basis of technical solutions of the utility model, all improvement of carrying out individual part according to the utility model principle or equivalents, all should not get rid of outside protection domain of the present utility model.
Claims (5)
