Abstract
The utility model relates to a universal joint, in particular to a rzeppa universal joint which comprises a bell-shaped casing. A connecting annular surface is arranged on the outer surface of the bell-shaped casing, a gear ring is connected onto the connecting annular surface in sleeved mode, a connecting shaft is arranged at one end of the bell-shaped casing, a star-shaped sleeve, a cage and a steel ball are arranged in the bell-shaped casing, the steel ball is located between the outer wall of the bell-shaped casing and the outer surface of the star-shaped sleeve, and the inner wall of the star-shaped sleeve comprises a spline surface and an inclined surface connected with the spline surface. The rzeppa universal joint is simple in structure and convenient to connect, and mainly solves the technical problem that a constant velocity universal joint is complicated in structure, two ends of the universal joint are connected inconveniently, and stability is poor in the prior art.
Description
Technical field
The utility model relates to a kind of universal joint, especially relates to a kind of rzeppa universal joint.
Background technique
Rzeppa universal joint is that automobile is with the critical component in the universal joint drive spindle; The usability of rzeppa universal joint and quality life-span directly influence the view of people to automobile itself; Along with popularizing of automobile, people require increasingly high to the travelling comfort of vehicle operation performance and use.For a long time, constant velocity universal joint exists all the time and is easy to generate noise and vibration, short-life defective in the using process.Chinese patent discloses a kind of rzeppa universal joint, and (notice of authorization number: CN2690657), it comprises outer race, star sleeve, retainer and steel ball, and retainer is contained in the outer race inner ball surface; Steel ball places in six fenestras of retainer; And contact with the star sleeve outer spherical surface, the outer race inner ball surface is made up of three sections variation circular arcs, and wherein the radius of arc at two ends is identical; The radius of arc of intermediate section is different from the radius of arc at two ends, these three sections smooth connections of circular arc; After the assembling, the outer spherical surface of retainer contacts with the circular arc at outer race inner ball surface two ends, has the gap between outer race inner ball surface intermediate section circular arc and retainer outer spherical surface.But this constant velocity universal joint two ends are not that easily stability is good inadequately when connecting external member.
The model utility content
The utility model provides a kind of simple in structure, the convenient rzeppa universal joint that connects, and it mainly is to solve comparatively complicacy of existing in prior technology constant velocity universal joint structure, the universal joint two ends connect inconvenient, stable imperfect technical problem.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The rzeppa universal joint of the utility model; Comprise outer race, the outer surface of described outer race is provided with the connection anchor ring, on described connection anchor ring, is socketed with gear ring; End at outer race is provided with coupling shaft; Outer race inside is provided with star sleeve, retainer and steel ball, and steel ball is between outer race outer wall and star sleeve outer surface, and the star sleeve inwall comprises spline surface and the plane of inclination that links to each other with spline surface.Outer surface at outer race is provided with gear ring, can outer connection member, and make things convenient for transmission and be connected.End at outer race is provided with coupling shaft, is provided with spline surface at the star sleeve inwall simultaneously, makes things convenient for universal joint that transmission is carried out in the parts connection that two needs rotate each other, and is simple in structure, easy to operate.
As preferably, described outer race is provided with the gyration center mark, and described gyration center mark is positioned at the plane that intersect spline surface and plane of inclination.Make the steel ball running more freely, guarantee freely to rotate each other that it is little to wear and tear by two members that universal joint connects.
As preferably, on coupling shaft, be provided with involute outer spline, can be connected with the motor differential mechanism of automobile like this.
As preferably, have involute inner spline on the spline surface of described star sleeve internal surface.Can be connected with the axostylus axostyle of vehicle like this.
Therefore, the rzeppa universal joint of the utility model is provided with gear ring on the coupling shaft of an end of outer race; Conveniently be connected with external member; Improve universal joint power, other parts of universal joint and Motor Vehicle are connected through external splines in the involute, simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model.
Component, position and numbering among the figure: outer race 1, star sleeve 2, steel ball 3, retainer 4, gear ring 5, involute outer spline 6, involute inner spline 7, gyration center mark 8, plane of inclination 9, coupling shaft 10.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment:
As shown in Figure 1, rzeppa universal joint comprises outer race 1, and the outer surface of outer race 1 is provided with the connection anchor ring, on described connection anchor ring, is socketed with gear ring 5, is provided with coupling shaft 10 at an end of outer race 1, on coupling shaft 10, is provided with involute outer spline 6.Outer race 1 inside is provided with star sleeve 2, retainer 4 and steel ball 3, and steel ball 3 is between outer race 1 outer wall and star sleeve 2 outer surfaces, and star sleeve 2 inwalls comprise spline surface and the plane of inclination that links to each other with spline surface 9.Have involute inner spline 7 on the spline surface of star sleeve 2 internal surfaces.Change centre mark 8 once in the plane that intersect spline surface and plane of inclination.
During use, at involute outer spline 6 place's junctor motor vehicle engine differential mechanisms of outer race 1, involute inner spline in star sleeve 27 connects the axostylus axostyle of automobiles bottom, the more whole device Motor Vehicle of packing into is got final product.
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.
