Embodiment
More fully example embodiment is described referring now to accompanying drawing.But example embodiment can be implemented in a variety of forms, and should not be understood to be limited to mode of execution set forth herein; On the contrary, these mode of executions are provided to make the present invention comprehensively with complete, and the design of example embodiment will be conveyed to those skilled in the art all sidedly.Reference character identical in figure represents same or similar structure, thus will omit their detailed description.
Figure 1 shows that the Hooks coupling universal coupling of the embodiment of the present invention, comprise a jack shaft 1, two coupling hooks 3 and two force bearing ring assemblies 5, and be respectively provided with the middle jaw 2 of at the two ends of jack shaft 1.Coupling hook 3 and middle jaw 2 are suitable, are coupled together both them by force bearing ring assembly 5.
As shown in Figure 4 and Figure 5, middle jaw 2 and coupling hook 3 are all relatively set with the gudgeon 4 that two coaxial lines are arranged, that is, the axis of two gudgeons on middle jaw 2 overlaps, and the axis of two gudgeons on coupling hook 3 also overlaps.The gudgeon of existing Hooks coupling universal coupling is positioned on cross axle, and on jaw, be provided with bearing, gudgeon 4 is then arranged on middle jaw 2 and coupling hook 3 by the present invention, and bearing 6 is set on force bearing ring assembly 5 for coordinating with these gudgeons 4, bearing 6 can adopt rolling bearing or sliding bearing.
With reference to figure 2 and Fig. 3, force bearing ring assembly 5 be provided with two groups respectively can for the gudgeon 4 on middle jaw 2 and coupling hook 3 insert to hole.Each group is all made up of pair of bearings mounting hole hole, and the internal diameter size of these two bearing mounting holes is identical, axes coincide, can be used for installing bearing 6.As shown in Figure 3, bearing mounting hole 501 and bearing mounting hole 502 form first group to hole, bearing mounting hole 503 and bearing mounting hole 504 form second group to hole.These two groups is orthogonal to the axis in hole, the gudgeon 4 on middle jaw 2 and coupling hook 3 can be inserted into wherein one group in hole, and to coordinate the bearing 6 in hole.
The force bearing ring assembly 5 of present embodiment is hollow oblate cylinder, and two groups are arranged on the sidewall of this force bearing ring assembly 5 hole, but in the present invention, the shape of force bearing ring assembly 5 does not limit.Gudgeon 4 directly can be inserted into hole from the outside of force bearing ring assembly 5, and in the present embodiment, and gudgeon 4 is inserted into from the inside of force bearing ring assembly 5 hole.In present embodiment, two groups are positioned at same plane to the axis in hole, but both axis also can not in same plane.
Force bearing ring assembly 5 is docked to be connected by two symmetrical semi-rings 51,52 and forms, the interface of these two semi-rings 51,52 perpendicular to the axis place plane in hole and with the wherein dead in line to hole, there is in the end face center of force bearing ring assembly 5 through hole 53 that can pass for coupling hook 3 and middle jaw 2, be connected with this through hole 53 to hole, gudgeon 4 is inserted in hole by this through hole 53.
As shown in Figures 4 and 5, middle jaw 2 and coupling hook 3 have the body of rod that a cross section is rectangle, gudgeon 4 is arranged on one end of the body of rod, when middle jaw 2 and coupling hook 3 are inserted between through hole 53 from two ends, due to two groups, same plane is positioned to the axis in hole, therefore, need middle jaw 2 and coupling hook 3 are dodged mutually.For this reason, on middle jaw 2 and coupling hook 3, be oppositely installed between its two gudgeons 4 two semicircle cones 20, the axis of these two two semicircular cones 20 and the dead in line of gudgeon 4, angle between the bus of each semicircle cone and its own axes is 45 °, and the angle between the bus of two semicircle cones 20 is 90 °.By arranging semicircle cone 20, the interference of coupling hook 3 and middle jaw 2 can be avoided, can also ensure that gudgeon 4 place has maximum material thickness.Each surface of middle jaw 2 and coupling hook 3 all belongs to finished surface, fine finishing can be carried out to each surface, higher dimensional accuracy can be obtained, weight is symmetrical, the rotation axis coincident of each part, running accuracy is high in the running to make Hooks coupling universal coupling, vibrates little, especially in high speed and the occasion having balance requirement, be easy to meet design requirement.
See Fig. 1, namely the line of the central point of the cross section of each coupling hook 3 is the axis of this coupling hook, and the angle theta between the axis of coupling hook 3 and jack shaft 1 is the axis knuckle of this Hooks coupling universal coupling, is also the offset angle of Hooks coupling universal coupling.The offset angle of this Hooks coupling universal coupling is between 0 ° to 25 °, and that is, coupling hook 3 can relative to jack shaft 1 maximum deflection 25 °.In FIG, the axis of two coupling hooks 3 is parallel to each other, and be now called Z-type layout pattern, and in the figure 7, the axis of two coupling hooks 3 is positioned at the same side of central shaft 1, is now called W type layout pattern.
As shown in Figures 2 and 3, semi-ring 51 and semi-ring 52 all establish screw 57, a buckle closure 54 is respectively provided with at the two ends of these two semi-rings, when assembling, four bearings 6 are enclosed within four gudgeons 4, semi-ring 51 and semi-ring 52 split docking are got up, in the process of split, makes four bearings 6 enter into two to hole.In figure 3, bearing mounting hole 503 and bearing mounting hole 504 are complete circular holes, the bearing corresponding with these two holes can directly insert, and bearing mounting hole 501 and bearing mounting hole 502 are put together by two half bore, can directly two bearing obvolvents be got up.After two semi-ring docking, two buckle closures 54 are fastened on the end face of these two semi-rings, then screw in screw 57 with screw 58 through buckle closure 54, buckle closure 54 and two semi-rings are connected.
In order to improve the effect be connected and fixed, in the present embodiment, the periphery wall of semi-ring 51,52 is provided with round table surface 55, buckle closure 54 is provided with and is combined to compress inclined-plane 56 in semi-ring with round table surface 55.
The means of fixation of semi-ring 51 and semi-ring 52 is not limited thereto, and can also adopt other mode.As shown in Figure 6, in another mode of execution of the present invention, force bearing ring assembly 5 outer wall two ends are respectively provided with a step surface, step surface is arranged with the cranse 59 with its interference fit, step surface is also provided with the circlip 50 be positioned at outside cranse 59.By the effect of this cranse 59, also two semi-rings 51 and 52 can be fixed up, thus form complete force bearing ring assembly 5.
Operationally, if the coupling hook on the left of this Hooks coupling universal coupling 3 is connected with driving shaft, and the coupling hook 3 on right side is connected with driven shaft, so the moment of torsion pass order of this Hooks coupling universal coupling is: the coupling hook 3 on the force bearing ring assembly 5 → bearing → right side on the middle jaw 2 → bearing → right side on middle jaw 2 → jack shaft 1 → right side in the force bearing ring assembly 5 → bearing → left side in the coupling hook 3 → bearing → left side in left side.
Below illustrative embodiments of the present invention is illustrate and described particularly.Should be appreciated that, the invention is not restricted to disclosed mode of execution, on the contrary, the invention is intended to contain and be included in various amendment in the spirit and scope of claims and equivalent arrangements.
