Make the hand pulling type spline connection structure that is easy and can be used for high speed or low speed splined shaft.
To achieve the above object, solution provided by the utility model is: including circlip for shaft, the first spline
Axis, the second splined shaft, spring and spline housing；
First splined shaft has the first spline segment and primary optic axis section；
Second splined shaft has the second spline segment and the second optical axis section；
The spline housing is sleeved on the first spline segment；
The spring pocket is on the first splined shaft, and one end is fixed on primary optic axis section by circlip for shaft
On, another section contacts with spline housing；
First spline segment is equipped with positive stop lug boss；
The spline housing inner wall circumferentially has the limiting groove matched with positive stop lug boss, and spline housing connects with spring
Contravention is additionally provided with the limiting through hole matched with positive stop lug boss radial cross-sectional profile.
Further, the positive stop lug boss can have multiple, and it is radially symmetrical or and be uniformly distributed circumferentially,
It can make splined shaft more smoothly high speed rotation in this way.
Further, the primary optic axis section diameter is greater than the first spline segment diameter, and the first splined shaft is made to form the shaft shoulder,
To realize that the shaft shoulder of spline housing and the first splined shaft is seamless applying, the axial float of spline housing is eliminated.Similarly, described second
Second spline segment diameter of splined shaft is less than the second smooth shaft section diameter.
Further, in order to be more convenient when operating spline housing, one end that the spline housing is contacted with spring has radial
Extension.
Further, there are two the positive stop lug boss, the positive stop lug boss is formed by axial transversal with the first spline segment
Face is dolioform.
The beneficial effects of the utility model are:
(1) the utility model is to increase positive stop lug boss on splined shaft, and be provided with and positive stop lug boss phase on spline housing
The limiting groove of cooperation, so that spline housing has self-locking function；
(2) one end that the spline housing of the utility model is contacted with spring has radially outwardly extending portion, can be in operation spline housing
When it is more convenient, operate it is more labor-saving；
(3) the optical axis section of the first splined shaft of the utility model and the second splined shaft is greater than the equal diameter of spline segment, makes in this way
It must spend strong set that self-locking function can be better achieved；
(4) positive stop lug boss being arranged on the first spline segment of the utility model is along axial regular uniform distribution, Ke Yiji
Big reduction influences experiment parameter because positive stop lug boss is unevenly distributed；
(5) the utility model embodiment uses cross section for dolioform positive stop lug boss, can increase spline housing it is self-locking when
The contact area of limiting groove and positive stop lug boss, so that limit is relatively reliable.

Specific embodiment
The utility model is further described below in conjunction with drawings and the specific embodiments.
Fig. 1-Fig. 7 gives a specific embodiment of the utility model.
Can be seen that the present embodiment from Fig. 1, Fig. 2 and Fig. 3 includes circlip for shaft, the first splined shaft 12, the second spline
Axis 15, spring and spline housing 14.First splined shaft 12 is made of the first spline segment 122 and primary optic axis section 121；Second splined shaft
15 are made of the second spline segment 151 and the second optical axis section 152；It sets on first spline segment 122 and is limited there are two radially symmetrical
Boss；Spline housing 14 is sleeved on the first splined shaft 12, and spring one end is fixed on the first light by two circlip for shaft 11
On shaft part 121, the spring other end is contacted with spline housing 14, and when spline housing 14 and the first splined shaft 12 and the second splined shaft 15
When in meshing state, the natural length of spring is longer than circlip for shaft to the distance length of spline housing 14；Primary optic axis section
Diameter be greater than the first spline segment diameter, make the first splined shaft formed the shaft shoulder, similarly, the second spline segment diameter of the second splined shaft
Less than the second smooth shaft section diameter, the shaft shoulder is also formed.
Lead to from fig. 4, it can be seen that spline housing 14 is equipped with limit compatible with the positive stop lug boss on the first spline segment 122
Hole 142.
From fig. 5, it can be seen that circumferentially arranged in spline housing 14 have limiting groove 141.
As can be seen from Figures 6 and 7, it is radial right that two positive stop lug boss 16 and the first spline segment, which are formed by axial cross section,
What is claimed is dolioform, and the limiting through hole 142 of corresponding spline housing end is also dolioform.It in other embodiments can be using along week
To equally distributed multiple positive stop lug boss.
The specific work process of the utility model embodiment:
Referring to Fig. 1, when spline housing 14 and the first splined shaft 12 and the second splined shaft 15 are in meshing state, due to spring
Along axial elastic force effect, spline housing 14 and the shaft shoulder of the second splined shaft 15 are seamless applying, generation when eliminating spline housing rotation
Axial float；Referring to fig. 2, Fig. 3, when needing to be detached from one end splined shaft, spline housing 14 pulls to the left along axial direction, makes limit convex
Platform 16 passes through the dolioform limiting through hole of 14 left end of spline housing, and spline housing 14 (being rotated by 90 °), makes clockwise or counterclockwise
The positive stop lug boss 16 obtained on the first splined shaft 12 is matched with the limiting through hole on spline housing 14 into spline housing 14, works as limit convex
After platform 16 is completely into spline housing 14, spline housing 14 is unclamped, by the limiting through hole of the positive stop lug boss 16 of splined shaft, spline housing 14
Spline housing 14 can be locked on the first splined shaft with the restoring force of spring.
