As the further improvement of the utility model, this three-way concurrent revolute pair by an axle, spherical pair and one even ball connecting end, two be with dull and stereotyped connecting end to form; Spherical pair is fixed on an end of axle, and its centre of sphere is on the axis of axle; An end that connects the ball connecting end ball of spherical pair of ining succession; The dull and stereotyped connecting end of said band is installed on the axle; Be to be inconjunction with the through hole flat board on the connecting end; Its dull and stereotyped face keeps suitable distance with the axis of connecting end separately, makes with dull and stereotyped connecting end, connects three-way the intersecting at a point of axis of the connecting end of ball connecting end.
As the further improvement of the utility model, the connecting end of this three-way concurrent revolute pair is band straight-bar connecting end, and this band straight-bar connecting end is the straight-bar that is inconjunction with annular bearing on the connecting end.
As the further improvement of the utility model, the connecting end of this three-way concurrent revolute pair is band curved bar connecting end, and this band curved bar connecting end is the curved bar that is inconjunction with annular bearing on the connecting end.
After adopting the revolute pair structure of the utility model, the axis of three connecting ends of revolute pair has been realized the three-way common point that intersects at, for the design production of some new machineries, new equipment provides key mechanism.The utility model simple in structure, easy to manufacture.

Embodiment
The three-way concurrent revolute pair of the utility model is made up of axle and connecting end.Like Fig. 1, shown in Figure 3, this three-way concurrent revolute pair is provided with three connecting ends 1, and the axis of said three connecting ends is always three-way to intersect at a point 2, and said three connecting ends 1 all can be put 2 around this and rotate; This three-way concurrent revolute pair connecting end 1 can be connected with component that it is complementary.When the structure of three-way concurrent revolute pair adopts main shaft 3, countershaft 4 and is with dull and stereotyped connecting end 5,6,7 to form, this main shaft 3 one ends fluting, and there is through hole the groove both sides; Countershaft 4 is installed; The intersect vertical axis of this main shaft 3, countershaft 4, the other end of this main shaft 4 has screw thread, the nut of can screwing on.This is with dull and stereotyped connecting end is to be inconjunction with through hole flat board 8 on the connecting end 1, will be with dull and stereotyped connecting end 5,6 to be installed on the main shaft 3, be with dull and stereotyped connecting end 7 to be installed on the countershaft 4 by through hole.This keeps suitable distance with the face of the flat board 8 of dull and stereotyped connecting end 5,6,7 and connecting end 1 axis separately; Make and be with dull and stereotyped connecting end 5,6,7 to rotate in any case; The axis of its connecting end 1 is three-way all the time to intersect at a point 2, and this point 2 is exactly the crossing point of axes of this main shaft 3, countershaft 4.
As the another kind of mode of execution of the utility model, like Fig. 2, shown in Figure 3, the structure of three-way concurrent revolute pair also can adopt an axle 9, spherical pair 10 and one, and even ball connecting end 11, two are with dull and stereotyped connecting end 5,6 to constitute.Spherical pair 10 is fixed on an end of axle 9, and its centre of sphere is on the axis of axle 9.An end that connects ball connecting end 11 ball of spherical pair 10 of ining succession, the other end is a connecting end 1, makes this connect ball connecting end 11 and rotates in any case, its connecting end 1 axis all passes through the centre of sphere of spherical pair 10.The dull and stereotyped connecting end 5,6 of said band is installed on the axle 9; Be to be inconjunction with through hole dull and stereotyped 8 on the connecting end 1; Its face of dull and stereotyped 8 keeps suitable distance with the axis of connecting end 1 separately; Make and be with dull and stereotyped connecting end 5,6, connect ball connecting end 11 and rotate in any case, the axis of its connecting end 1 is three-way all the time to intersect at a point 2, and this point 2 is exactly the centre of sphere of spherical pair 10.
As the another kind of mode of execution of the utility model, as shown in Figure 4, the structure of three-way concurrent revolute pair connecting end 1 also can adopt band straight-bar connecting end, and this band straight-bar connecting end is the straight-bar 12 that is inconjunction with annular bearing on the connecting end 1.
As the another kind of mode of execution of the utility model, as shown in Figure 5, the structure of three-way concurrent revolute pair connecting end 1 can also adopt band curved bar connecting end, and this band curved bar connecting end is the curved bar 13 that is inconjunction with annular bearing on the connecting end 1.This axis that curved bar 13 and connecting end 1 can be set equally keeps suitable distance, guarantees that the connecting end 1 of three-way concurrent revolute pair rotates in any case, and three axis of its connecting end 1 intersect at a point 2 all the time.
