Abstract
The utility model discloses an axial positioning structure for a spline connecting sleeve, which comprises a spline connecting sleeve with spline holes inside, and two spline shafts inserted in the spline connecting sleeve, and is characterized in that a plurality of positioning holes are uniformly formed on one side of the spline connecting sleeve in the circumferential direction; an elastic positioning pin is arranged in each positioning hole; annular positioning grooves are formed on the spline shafts in the positions corresponding to the elastic positioning pins; and the heads of the elastic positioning pins are clamped in the positioning grooves. The utility model has the advantages that the coaxiality of the spline shafts connected at the two ends can be ensured, so that mechanical wear and noises caused by disalignment can be reduced; balls are clamped in the positioning grooves under the action of springs, so that the spline connecting sleeve is ensured that the axial positioning is firm and axial shifting does not occur easily; and the elastic positioning pins are mounted and dismounted conveniently and quickly and are not damaged easily, thereby satisfying the connection requirements of components needing to be mounted and dismounted frequently.
Description
Technical field
The utility model is particularly related to a kind of spline connecting sleeve axial positioning structure.
Background technique
It is a kind of linkage structure comparatively common in the mechanical transmission that spline connects, motor output shaft and gearbox input shaft are generally splined shaft on electric vehicle, connect transmission by a spline connecting sleeve exactly between the two, need it is carried out axially locating after the spline connecting sleeve installs.The axially locating of spline connecting sleeve mainly contains two kinds of modes of locating stud and jackscrew location at present.Use the locating stud location to be not easy to dismounting, in disassembly process, damage spline easily; Use the jackscrew location to be difficult to guarantee the coaxality of spline connecting sleeve two ends splined shaft, and owing to be Spielpassung between spline connecting sleeve and the splined shaft, therefore jackscrew can be subjected to shearing force when transmission, cause jackscrew loosening easily, thereby make the spline connecting sleeve produce axial float because of axially locating loses efficacy.
Summary of the invention
The technical problems to be solved in the utility model is that a kind of coaxality that can guarantee to connect will be provided, and firm position is difficult for producing axial float, spline connecting sleeve axial positioning structure convenient to disassembly.
In comprising, establishes the spline connecting sleeve axial positioning structure that the utility model relates to spline connecting sleeve and two splined shafts that are inserted in the spline connecting sleeve of splined hole, its special way is: along the circumferential direction be evenly equipped with a plurality of positioning holes in spline connecting sleeve one side, in positioning hole, be respectively equipped with elastic positioning pin, be provided with annular positioning groove on the splined shaft corresponding with elastic positioning pin, described elastic positioning pin head is stuck in the locating slot.
Above-mentioned spline connecting sleeve axial positioning structure, described elastic positioning pin are to be made of the ball, the spring peace crown silk that are installed in successively in the positioning hole.
Above-mentioned spline connecting sleeve axial positioning structure, described positioning hole inner port is a taper mouth, the path of taper mouth is less than ball diameter, thereby blocks ball.
The utility model has the advantages that: can guarantee the coaxality that two splined shafts connect by elastic positioning pin, reduce the mechanical wear and the noise that cause because of decentraction; Because the elastic positioning pin head is stuck in the locating slot, therefore can guarantee that spline connecting sleeve axially locating is firm, be difficult for producing axial float; And elastic positioning pin is convenient to disassembly, not fragile, the often connection of the parts of dismounting of can satisfying the demand.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: spline connecting sleeve 1, positioning hole 101, splined shaft 2, locating slot 201, tack jackscrew 3, spring 4, ball 5.
Embodiment
As shown in the figure, the utility model has spline connecting sleeve 1 and two splined shafts 2 that are inserted in the spline connecting sleeve 1 of establishing splined hole in one, along the circumferential direction be evenly equipped with a plurality of positioning holes 101 in spline connecting sleeve 1 one sides, present embodiment positioning hole 101 is an example with three, and reality is not limited by present embodiment.In positioning hole 101, be respectively equipped with elastic positioning pin, described elastic positioning pin is to be made of the ball 5, the spring 4 peaceful crown silks 3 that are installed in successively in the positioning hole 101, on the splined shaft corresponding 2, being provided with annular positioning groove 201, described ball 5(elastic positioning pin head with elastic positioning pin) active force by spring 4 is stuck in the locating slot 201.Described positioning hole 101 inner port are taper mouth, and the path of taper mouth is less than ball 5 diameters, to block ball 5.
Claims (3)
1. spline connecting sleeve axial positioning structure, establish spline connecting sleeve and two splined shafts that are inserted in the spline connecting sleeve of splined hole in comprising, it is characterized in that: along the circumferential direction be evenly equipped with a plurality of positioning holes in spline connecting sleeve one side, in positioning hole, be respectively equipped with elastic positioning pin, be provided with annular positioning groove on the splined shaft corresponding with elastic positioning pin, described elastic positioning pin head is stuck in the locating slot.
2. spline connecting sleeve axial positioning structure according to claim 1 is characterized in that: described elastic positioning pin is to be made of the ball, the spring peace crown silk that are installed in successively in the positioning hole.
