Embodiment
Embodiment one:
As shown in Figure 1, the high elasticity spline of the present embodiment transmission shaft that stretches comprises a mandrel 1 and an axle sleeve 2, and described axle sleeve 2 is enclosed within outside described mandrel 1.
Coaxially be installed with the elasticity bushing pipe 3 be close together with axle sleeve 2 inwall in described axle sleeve 2, the two ends of elasticity bushing pipe 3 are all located with back-up ring 4 and interior jump ring 5.Mandrel 1 and the fitting surface of elasticity bushing pipe 3 are straight multi-prismatic surface (described " fitting surface " refers on the length section that contacts with mandrel at elasticity bushing pipe, the internal face of elasticity bushing pipe and the outer wall of mandrel).There is between mandrel 1 and elasticity bushing pipe 3 elasticity concession space that is radial and circumference, can under buffering and the condition maintaining free-extension transmitting torque.
Above-mentioned elasticity bushing pipe 3 can adopt following several specific constructive form:
1) the first structural type: as shown in Figures 2 and 3, the internal face of described axle sleeve 2 is straight multi-prismatic surface, described elasticity bushing pipe 3 by several equally distributed and be close to sleeve lining face tiger's jaw shape wire spring 35 arrangement be formed by stacking.Conveniently to carrying out oiling in this transmission shaft and draining the oil, to facilitate lubrication, also can offer a symmetrical oil hole and a drain oil on the wall of axle sleeve 2, it is not shown that oil hole and drain oil all install a plug screw 13().
In conjunction with as shown in Figure 1, Figure 2 and Fig. 3, existing its working principle to be described below: tiger's jaw shape wire spring 35 has two stations, and when being in original station ɑ °, tiger's jaw is opened, and has obvious spacing gap 25 between upperlip; When being in fully loaded station β °, tiger's jaw is closed, and spacing gap 25 is eliminated.
Tiger's jaw shape wire spring generation resiliently deformable and curving inwardly, the A point turned on it when mandrel 1 is overlapping with the B point on tiger's jaw shape wire spring 35, this elastic strain eliminates the spacing gap 25 of tiger's jaw shape wire spring 35, now mandrel 1 props up tiger's jaw shape wire spring 35 completely, and tiger's jaw shape wire spring 35 can not continue to produce deformation, so, when mandrel 1 continues to rotate, A point can not cross B point, and mandrel 1 just can drive axle sleeve 2 to rotate together.
Certainly, when designing this transmission shaft, answering the size of the size of the good mandrel 1 of attentional manipulation and elasticity bushing pipe 3 suitable, avoiding mandrel 1 to occur skidding (the A point namely on mandrel crosses the phenomenon of the B point on tiger's jaw shape wire spring) when rotated.
2) the second structural type: as shown in figures 4 a and 4b, the arcuate line spring 31 that this elasticity bushing pipe 3 is fixed in axle sleeve by several arranges and is formed by stacking, arcuate line spring 31 has two kinds of fixed forms, and a kind of form is (if Fig. 4 is a) that all arcuate line springs 31 are all fixed on the inwall of axle sleeve 2 by screw 12 and the positive stop key 38 that is connected with this screw thread; Another kind of form (as Fig. 4 b) is that all arcuate line springs 31 are all ridden and are stuck on dovetail positive stop key 39, relies on the dovetail section on dovetail positive stop key 39 to be fixed on the inwall of axle sleeve 2.Conveniently to carrying out oiling in this transmission shaft and draining the oil, to facilitate lubrication and cleaning, also can offer a symmetrical oil hole and a drain oil on the wall of axle sleeve 2, it is not shown that oil hole and drain oil all install a plug screw 13().
