Abstract
The utility model discloses a high locating spline shaft. The spline shaft comprises a shaft body consisting of a front end part, a spline part I, a spline part II, a cylinder part, a spline part III and a back end part, wherein retainer ring grooves are formed between the spline part I and the front end part as well as between the spline part I and the spline part II; a retainer ring groove is formed between the spline part II and the cylinder part; a retainer ring groove is formed between the spline part III and the back end part; the spline part I, the spline part II and the spline part III are all provided with edges projected outwards; the edges are parallel to the upper end surfaces of the respective splines; protection cones are arranged on the end surfaces of the front end part and the back end part. The high locating spline shaft has the advantages that the structure is simple; the edges are arranged on the spline parts for effectively locating the positions of transmission parts matched with the spline parts, so that the matching is more compact, the deviation abrasion of the transmission parts is reduced, and the service life of the transmission parts is prolonged; the protection cones of the front end part and the back end part can effectively protect the end surface of the shaft body, so that the operation is more stable.
Description
Technical field
The utility model belongs to mechanical transmissioning technology field, especially relates to a kind of high location splined shaft.
Background technique
Motor is the power take-off mechanism of various Motor Vehicle, the output of its power source be mainly by various axles and with the coordinating of gear, as common pto＝power take-off, it plays an important role splined shaft in power system.Existing splined shaft is general main to be comprised of columned axis body, then on the external cylindrical surface of axis body, offers spline part, and this spline part is by mating connection with transmission part, and then drive axis body rotates.But the locating face that there is no transmission part on existing splined shaft, when long-time use, this transmission part is connected to easily skew wearing and tearing a little on splined shaft, has a strong impact on the actual transmission effect of transmission part, after long-time use, easily cause damage, be therefore necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existing for above-mentioned prior art, provides a kind of simple in structure, can effectively reduce the height location splined shaft that transmission part weares and teares and extends its working life.
To achieve these goals, the technological scheme that the utility model adopts is: a kind of high location splined shaft, comprise the axis body being formed by front end, one of spline, two of splines, columnar portion, three of splines and rearward end, between two of one of described spline and front end and splines, be provided with circlip groove, between two of described splines and columnar portion, be provided with circlip groove, between three of described splines and rearward end, be provided with circlip groove; On three of one of described spline, two of splines and splines, be provided with the edge of outwardly convex, described edge is parallel to each other with the upper-end surface of spline separately; On the end face of described front end and rearward end, be provided with and protect cone.
The described cone that protects is for semi-enclosed structure.
Described edge is 1:5 with the ratio of each self-corresponding spline height.
Adopt after said structure, the advantage that compared to the prior art the utility model had is: of the present utility model simple in structure, edge is set on spline part and can effectively locates the position of the transmission part being mated, make its cooperation compacter, reduce the skew wearing and tearing of transmission part, extend its working life; Front end thereafter end protect the end face that cone can effectively be protected axis body, make its more stable work.
Accompanying drawing explanation
Fig. 1 is plane structure schematic diagram of the present utility model.
Fig. 2 is the cone plane structure schematic diagram that protects of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated, the following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, is shown in shown in Fig. 1 and Fig. 2: a kind of high location splined shaft, comprises axis body and protect cone 40; Described axis body consists of front end 10, one 11 of spline, two 12 of splines, columnar portion 13, three 14 of splines and rearward end 15.Between two 12 of one 11 of described spline and front end 10 and splines, be provided with circlip groove 20, between two 12 of described splines and columnar portion 13, be provided with circlip groove 20, between three 14 of described splines and rearward end 15, be provided with circlip groove 20, circlip groove 20 can allow gear not easy to wear and rotate more stable in rotation process after back-up ring is installed.The edge 30 that is provided with outwardly convex on three 14 of one 11 of described spline, two 12 of splines and splines, the upper-end surface of described edge 30 and separately spline (11,12,14) is parallel to each other and the height ratio between it is 1:5.On the end face of described front end 10 and rearward end 15, be provided with and protect cone 40; the described cone 40 that protects is for semi-enclosed structure; its opening end and each self-corresponding end end face are fitted, and can effectively protect so in the course of the work the end face of axis body, make its more stable work.
