Abstract
The utility model relates to a spline coupling structure, which comprises an inner spline, an outer spline and a spline adapter sleeve arranged between the inner spline and the outer spline. Besides, the spline coupling structure is made from a composite material with certain ductility and strength, both the inner and outer sides of the spline adapter sleeve are provided with splines which respectively match with the inner spline and the outer spline, each spline on the outer side of the spline adapter sleeve is provided with grooves, and each spline arranged on the inner side of the spline adapter sleeve is in the shape of a circular arc. The spline coupling structure utilizes the spline adapter sleeve made from the composite material, and each spline on the outer side of the spline adapter sleeve is provided with grooves, thereby guaranteeing certain tightness on the contact surface of the outer spline and reducing eccentricity of the two splines. In addition, the spline coupling structure is convenient in mounting and dismounting and simple in structure, and reduces cost for replacement.
Description
Technical field
The utility model relates to a kind of spline connecting structure.
Background technique
At present, the torsion pass of number axis all is a mode of utilizing gear or inside and outside spline engagement mostly, comes the torsion pass reliability higher by spline, but lacks the effect of self-aligning, vibration damping and overload protection, when load is excessive, causes the damage of important axial workpiece easily.
Summary of the invention
Goal of the invention
The purpose of this utility model is to guarantee to realize the function of two transmission shaft self-alignings, vibration damping and overload protection on the reliable advantage of former spline torsion pass.
The technical solution of the utility model is, connecting structure comprises a spline switching cover that is provided with between internal spline and external splines and the interior external splines, and the interior outside of described spline switching cover all is processed with spline, respectively with inside and outside spline fitted; The described spline switching cover outside each have groove above the spline, the spline that the spline switching cover is inboard be shaped as circular arc; The material of described spline switching cover is a composite material.
The utility model has adopted the spline switching cover of a composite material, on each spline in its outside, all have groove, when there is eccentric situation in two splined shafts of spline switching cover connection, external splines can be by the adjusting of self space width, can guarantee that the external splines surface of contact has certain tightness, improve the situation of two eccentric shafts, simultaneously, the external splines of this trough of belt can also play the effect of vibration damping when engine operation.The profile of tooth of internal spline is made up of several circular arcs, and when moment of torsion was excessive, this characteristics can make the spline spline switching cover internal spline of female splined shaft skid, and cause idle running, play the effect of overload protection.The spline switching cover is an individual part, and is easy to loading and unloading, simple in structure, even the spline wearing and tearing of work back need to change, also only needs to change a new spline switching cover, and need not change axial workpiece, reduced and changed the part cost.
Description of drawings
Fig. 1 is a schematic representation of the present utility model.
Embodiment
As shown in the figure, connecting structure comprises a spline switching cover 3 that is provided with between internal spline 2 and external splines 1 and the interior external splines, and be the composite material with certain toughness and intensity, the interior outside of described spline switching cover 3 all is processed with spline, respectively with inside and outside spline fitted; Described spline switching overlap 3 outsides each have groove above the spline, spline switching overlap 3 inboards spline be shaped as circular arc.
