Abstract
The utility model relates to a universal joint, in particular to a spherical shaft and Y-pipe universal joint. The spherical shaft and Y-pipe universal joint is mainly used for solving the technical problems that if installed in engineering machinery, a traditional universal joint is easy to rupture and has a shorter service life and the like when in use because a cross shaft is adopted by the traditional universal joint and the universal joint is provided with four pin shafts in the prior art. The spherical shaft and Y-pipe universal joint comprises a Y-pipe (1). A through hole (2) is arranged in the Y-pipe. The spherical shaft and Y-pipe universal joint is characterized in that three pin shafts of the Y-pipe (1) are respectively connected with a ball ring assembly (3); each ball ring assembly comprises an inner ring (4) and an outer ring (5); a roller pin (6) is arranged between each inner ring and each outer ring; and both ends of each roller pin are respectively provided with an elastic collar (7).
Description
Technical field
The utility model relates to a kind of universal joint, especially relates to a kind of spherical axial triradius universal joint.
Background technique
Universal-joint cross trunnion of the prior art is generally all formed by middle axis body and with the arm that middle axis body links into an integrated entity.Chinese patent discloses a kind of high tenacity Hooke's joint (notice of authorization number: CN 2464984Y); It comprises cross axle and is arranged on the needle roller around the cross axle spindle nose and puts and outer ring that needle roller is outer; The end of outer ring is provided with packing holder, on said packing holder, is provided with seal ring skeleton and seal placed on it; And the inboard of seal is provided with tilting outer lip and inside middle lip and the inner lip of lip successively, and two lips contact with the axle journal of cross axle; Tiltedly be provided with the grinding undercut of annular between internal face and the needle roller end face ring, the plane of technology groove connects really in flat end needle rollers end face and the bearing.What but this universal joint adopted is cross axle, if be installed in the engineering machinery, because it has four bearing pins, is easy to generate fracture when therefore using, and working life is shorter.
The model utility content
The utility model provides a kind of spherical axial triradius universal joint; It mainly is that what to solve that the existing in prior technology universal joint adopts is cross axle, if be installed in the engineering machinery, because it has four bearing pins; Therefore be easy to generate fracture when using, the technical problem that working life is short etc.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The spherical axial triradius universal joint of the utility model comprises trident, and trident inside is provided with through hole; All be connected with a ball assembly on three bearing pins of described trident; The ball assembly includes inner ring and outer ring, is provided with needle roller between inner ring and the outer ring, and the two ends of needle roller are provided with circlip.After all installing the ball assembly on three bearing pins of trident, the ball assembly can be rotated around bearing pin, and spider can be packed in the housing, thereby realizes the function of trident universal joint through spider, ball assembly.Owing to have only three bearing pins on the spider, so its join strength with the spider body is stronger, use can be born bigger power in engineering machinery the time, and difficult quilt twists off, fractures, and working life is longer.
As preferably, the side of the bearing pin of described trident is cambered outwards arc surface, and the end face of bearing pin is a sphere.Like this between the bearing pin of trident and the inner ring for line contacts, inner ring is comparatively smooth and easy rotationally, makes whole trident universal joint turn to convenient.
As preferably, the end of described through hole is provided with chamfering.Chamfering is set, is convenient to spider is assemblied in the trident universal joint.
Therefore, the utility model can not only play the effect of universal joint, and can make the intensity of whole trident universal joint stronger through the ball assembly is installed on three bearing pins of spider, can use in engineering machinery, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model;
Accompanying drawing 2 is a kind of structural representations of the utility model trident;
Accompanying drawing 4 is a kind of structural representations of the utility model ball assembly.
Component, position and numbering among the figure: trident 1, through hole 2, ball assembly 3, inner ring 4, outer ring 5, needle roller 6, circlip 7, arc surface 8, sphere 9, chamfering 10.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: the spherical axial triradius universal joint of this example; Like Fig. 1, Fig. 4, a trident 1 is arranged, trident inside is provided with through hole 2; All be connected with a ball assembly 3 on three bearing pins of trident; The ball assembly includes inner ring 4 and outer ring 5, is provided with needle roller 6 between inner ring and the outer ring, and the two ends of needle roller are provided with circlip 7.Like Fig. 2, Fig. 3, the side of the bearing pin of trident is cambered outwards arc surface 8, and the end face of bearing pin is a sphere 9, and the end of through hole is provided with chamfering 10.
During use, in the through hole 2 of trident 1, load onto axle, on three bearing pins of spider, install ball assembly 3, whole universal joint is encased in the housing gets final product again.
The above is merely the specific embodiment of the utility model; But the structure characteristic of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
Claims (3)
1. spherical axial triradius universal joint; Comprise trident (1); Trident inside is provided with through hole (2), it is characterized in that all being connected with a ball assembly (3) on three bearing pins of described trident (1), and the ball assembly includes inner ring (4) and outer ring (5); Be provided with needle roller (6) between inner ring and the outer ring, the two ends of needle roller are provided with circlip (7).
