Abstract
The utility model discloses a spline shaft. The spline shaft comprises a shaft body composed of a spline section and a round shaft section, wherein the surface of the shaft body is provided with quenching layers. The spline shaft provided by the utility model has the advantages that the surface hardness of the spline shaft is increased through the surface hardening of the spline shaft, so that the spline shaft is not easy to rupture, and the service life of the spline shaft is prolonged.
Description
Technical field
The utility model relates to a kind of splined shaft, and concrete is a kind of novel splined shaft.
Background technique
At present, splined shaft uses milling and gear hobbing to make usually, because cutting causes whole fracture easily, the moment of torsion strength is low, and the surface hardness of splined shaft is not enough, makes splined shaft rupture easily in working long hours, and causes having an accident; And splined shaft in use can have friction with other part always, and the time has been grown and will damage splined shaft, therefore needs a kind of novel splined shaft of design to satisfy user's demand.
The model utility content
The utility model proposes a kind of splined shaft, improved the surface hardness of splined shaft, make splined shaft be not easy fracture, increased the wear resistance of splined shaft, also guaranteed the toughness of splined shaft simultaneously, increased the working life of splined shaft.
The technical solution of the utility model is achieved in that a kind of splined shaft, comprises the axle body that is made of spline segment and circular shaft section two-part, and described axle body surface is provided with quench hardened case.
Further, the quench hardened case surface of the spline segment of described axle body also is provided with wear resistant coating.
Further, described wear resistant coating is the WC coating.
Further, the case depth of the quench hardened case of described axle body surface is 1.0-2.0mm, and surface hardness is 55-60HRC.
Further, the case depth of the quench hardened case of described axle body surface is 1.5mm, and surface hardness is 58HRC.
The beneficial effects of the utility model are: by to the splined shaft surface hardening, increased the surface hardness of splined shaft, make splined shaft be not easy fracture, and by the spline segment part surface being increased wear resistant coating, increased the wear resistance of splined shaft, guarantee the toughness of splined shaft simultaneously, thereby increased the working life of splined shaft.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model embodiment's structural representation;
Among the figure: 1, axle body; 2, spline segment; 3, quench hardened case; 4, wear resistant coating.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
A kind of splined shaft as shown in Figure 1 comprises the axle body 1 that is made of spline segment 2 and circular shaft section two-part, and described axle body 1 surface is provided with quench hardened case 3.
As preferably, quench hardened case 3 surfaces of the spline segment 2 of described axle body 1 also are provided with the WC coating.
As preferably, the case depth of the quench hardened case 3 on described axle body 1 surface is 1.5mm, and surface hardness is 58HRC.
By to the splined shaft surface hardening, increased the surface hardness of splined shaft, make splined shaft be not easy fracture, and by spline segment 2 part surfaces being increased wear resistant coating 4, the utility model embodiment adopts the WC coating, increase the wear resistance of splined shaft, guaranteed the toughness of splined shaft simultaneously, thereby increased the working life of splined shaft.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
