Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages of the invention and effect easily.
The invention will be further described with reference to the accompanying drawings and examples：
As shown in Fig. 1-3, a kind of bumper and absorbing shock shaft coupling, including it is the input shaft coupling section 2 and output connection of cylinder
Shaft part 4；The end face of 2 one end of the input shaft coupling section is provided with cross projection 202, and the other end is coaxially provided with columned input connection
The connection handle 201 of shaft part, and then correspondingly one end is provided with and is available for the cross of raised 202 insertion of cross recessed to export shaft coupling section 4
Groove 402, the other end is equally coaxially provided with the connection handle 401 of columned output shaft coupling section, the cross raised 202 and cross
All side clearances between connected in star 402 are filled with yielding rubber plate 9, and moment of torsion is obtained from motor to be input into shaft coupling section 2
When carrying out moment of torsion transmission by cross projection 202 afterwards, it is unlikely to directly to be touched with the generation rigid contact of cross groove 402
Hit, but carry out bumper and absorbing shock by the extruding of yielding rubber plate 9 elastic deformation.In input shaft coupling section 2 and the outside circle of output shaft coupling section 4
Input shaft coupling section overcoat 1 and output shaft coupling section overcoat 3 are respectively cased with cylinder, the input shaft coupling section overcoat 1 and output join
Shaft part overcoat 3 is the peviform structure that bottom is provided with small sircle hole, and the openend of peviform structure is provided with flanged plate 101, specifically may be used
Four flanged plates of bolt hole are provided with one piece of the openend butt welding of peviform structure, or directly by peviform structure and flanged plate
101 are made of one formula, are coupled together above-mentioned two overcoat with will pass through bolt 5, nut 6；Additionally, in the peviform structure
Inwall is additionally provided with the connection screw thread being enclosed within input shaft coupling section 2 and output shaft coupling 4 cylindrical outer side surfaces of section, and output shaft coupling section overcoat
Screw thread on 3 peviform inner structural wall is not screwed up completely with the screw thread in output shaft coupling section 4, as shown in Figure 1, therebetween
In the presence of one section of height for the screw thread of H screws up pre- allowance, occlusion transmitting torque is connected with output shaft coupling section 4 to be input into shaft coupling section 2
When, when moment of torsion exceedes certain limit, output shaft coupling section 4 will export rotational slippage in shaft coupling section overcoat 3, under moment of torsion effect
Automatically the screw thread with output shaft coupling section overcoat 3 near bottom is screwed up, while driving input shaft coupling section overcoat 1 relative to input shaft coupling
Section 2 is turned upwards, i.e., the input shaft coupling section overcoat 1 and output shaft coupling section overcoat 3 being connected with each other this moment are enclosed within defeated equivalent to one
Enter the big nut in shaft coupling section 2 and output shaft coupling section 4.When output shaft coupling section 4 is screwed down to extreme position, i.e., when height H is zero,
Stop skidding, shaft coupling section overcoat 1, input shaft coupling section 2, output shaft coupling section overcoat 3 and output shaft coupling section 4 are input into this moment and constitute one
Without the relative integral rigidity structure slided, lasting loading or continuation with moment of torsion increase, and the bolt 5 on flanged plate 101 is opened
Beginning plays a part of to transmit prevailing torque, and cross raised 202 and cross groove 402 start to undertake the work of auxiliary transmission moment of torsion
With, can avoid yielding rubber plate 9 because of excessive compression elastic failure, will suddenly apply or suddenly increase moment of torsion stage by stage by
Step transition transmission.For ease of being connected with motor or external equipment, the input shaft coupling section 2 and output shaft coupling section 4 of above-mentioned shaft coupling
On connection handle stretch out the small sircle hole of the peviform structural base respectively, for being connected with other associated actuator axles, connect tang
The internal blind hole structure with keyway is can be set to according to being actually needed, in order to couple with outside axle key, naturally it is also possible to use it
He connects mode, is not specifically limited herein.
Further, for preferably transmitting torque, bumper and absorbing shock connects in input shaft coupling section 2 and the occlusion of output shaft coupling section 4
Connect when finishing, the end face of the cross projection 202 and the bottom surface of cross groove 402 can not contact, as shown in L in Fig. 1, preferably
The spacing distance of L=2 millimeters is left, in order to avoid after the end face of cross projection 202 withstands the bottom surface of cross groove 402,
The side of cross projection 202 can not keep good contact with the groove inner wall of cross groove 402, so as to can not effectively pass
Torque delivery and the bumper and absorbing shock function of realizing yielding rubber plate 9.
Further, the screw thread at output shaft coupling section overcoat 3 bottom has 3~5 to buckle and is not screwed up with output shaft coupling section 4, i.e. H=
3P~5P, P are thread pitch, the buffer distance of output shaft coupling 4 rotational slippages of section are relatively adapted to during the H values, beneficial to high pulling torque point
Step transition is transmitted.
Further, the cross raised 202 and the respective center right angle rounding of cross groove 402, such as Fig. 4 institutes
Show that the center right angle rounding treatment of cross groove 402 forms rounding off curved surface, in case right angle is in transmitting torque
Stress concentration is produced, rupture of cracking occurs, influence the service life of shaft coupling.
Further, as depicted in figs. 1 and 2, raised 202 outside of the cross is tightly cased with rubber buffer ring 7, and described
Yielding rubber, 7 be sandwiched in input shaft coupling section 2 and output shaft coupling section 4 two contact end faces between, for alleviate two ends section axle between
Axial compression impact.
Further, the output shaft coupling section 4 is cased with screw thread spacing ring 8 away from one end of output shaft coupling section overcoat 3 bottom,
The screw thread spacing ring 8 is a circular ring, and circle ring inner wall is provided with the screw thread being engaged with output shaft coupling section 4.The screw thread is spacing
Ring 8 can also be directly prepared into nut type, be screwed up to install.When above-mentioned H values are reserved excessive, or operating mode is complicated, contains multiple
During limit torque value, can by adjust screw thread spacing ring 8 output shaft coupling section 4 on position come adjust output shaft coupling section 4 with it is defeated
The screw thread gone out between shaft coupling section overcoat 3 screws up length, makes H values when being not equal to zero, can also make input shaft coupling section overcoat 1, input
Shaft coupling section 2, output shaft coupling section overcoat 3 and output shaft coupling section 4 constitute one without the relative integral rigidity structure slided, with moment of torsion
Lasting loading or continue increase, the bolt 5 on flanged plate 101 undertake transmission prevailing torque effect, cross projection 202
With the effect that cross groove 402 undertakes auxiliary transmission moment of torsion, can avoid yielding rubber plate 9 because of excessive compression elastic failure,
To apply suddenly or the moment of torsion of increase progressively transition transmission stage by stage suddenly.
The above-described embodiments merely illustrate the principles and effects of the present invention, not for the limitation present invention.It is any ripe
The personage for knowing this technology all can carry out modifications and changes under without prejudice to spirit and scope of the invention to above-described embodiment.Cause
This, those of ordinary skill in the art is complete with institute under technological thought without departing from disclosed spirit such as
Into all equivalent modifications or change, should be covered by claim of the invention.
