Say, the relative rotation free degree between axial freedom and driving shaft and driven shaft between driving shaft and driven shaft is limited
System, that is to say and be rigidly connected, although being arranged such, driven shaft can be enable with driving shaft synchronous axial system, to driving shaft and from
The service life of moving axis is totally unfavorable.For example, after the axial freedom between driving shaft and driven shaft is limited, working as driving shaft
During axial moving, moving synchronous with driving shaft by driven shaft, so that driving shaft and driven shaft wear and tear because friction is produced, then
Fatigue failure is produced, or even risk of breakage occurs, and make the lost of life.Again for example, when driving shaft starts suddenly, driving shaft makes
It is the rotating speed that can reach driving shaft to obtain driven shaft, and the mode of this fast reaction of driven shaft is totally unfavorable to its shelf-life, according to
There is very big elastic-plastic deformation in momentum theory and collision theory, driven shaft internal material, within the extreme time so that driven
Axle is susceptible to fracture, and stops directly the power of whole equipment for the fracture of driven shaft, sometimes it also occur that driven
Axle flies out the danger hurted sb.'s feelings under the circumference of the high-speed rotation.
Therefore, it is necessary to design a kind of bindiny mechanism or shaft coupling that can effectively prevent driving shaft and driven axle fracture.

Specific embodiment
To make those skilled in the art be better understood from technical scheme, below in conjunction with the accompanying drawings and specific embodiment party
Formula elaborates to the present invention.
As depicted in figs. 1 and 2, embodiment of the invention discloses that a kind of shaft coupling for axial buffer, for connecting
Driving shaft and driven shaft 200, such as be used for connect gearbox output shaft (output shaft is used as driving shaft) and back axle input shaft it is (defeated
Enter axle as driven shaft 200), the shaft coupling for axial buffer includes active keeper 10, driven keeper 20 and axial direction
Buffer part；Active keeper 10 is used to be connected with driving shaft, and driven keeper 20 is used to be connected with driven shaft 200, axial buffer
Portion is arranged between active keeper 10 and driven keeper 20, and axial buffer portion includes two arch curved strips 30 being oppositely arranged,
It is provided with the relative face of two arch curved strips 30 and stretches to other side and spaced multiple fricting strips 31, and one of arch
Fricting strip 31 in curved strip 30 is stretched into the gap of corresponding two fricting strip 31 of another arch curved strip 30, so that two arches are curved
The interval of fricting strip 31 of bar 30 is stacked, wherein：When driving shaft and the axial direction of driven shaft 200 moving, between adjacent two fricting strip 31
Row buffering is entered to moving by the friction for producing.
From the foregoing, when driving shaft or driven shaft 200 occur axial moving, driving shaft or driven shaft 200 are by master
Vibration is passed to two arch curved strips 30 by dynamic keeper 10 or driven keeper 20, the stress of two arches curved strip 30 towards away from
Direction bends, so that relative superposition and adjacent fricting strip 31 is relatively moved, the movement is to overcome frictional force and obtain
, the frictional force has damping and cushioning effect to vibration, so as to slow down the axial moving of driving shaft and driven shaft 200,
So as to reduce the vibration between driving shaft and driven shaft 200, shaft coupling itself and driving shaft and driven shaft 200 are reduced
Abrasion, extends the service life of shaft coupling itself and driving shaft and driven shaft 200, and prevent driving shaft and driven shaft
200 there is risk of breakage.
As further selection, in the space between active keeper 10 and fricting strip 31 and driven keeper 20 with rub
The first stage clip 40 is provided with space between rub piece 31, two first stage clips 40 are used for be provided between adjacent two fricting strip 31
Pretightning force.
In a preferred embodiment of the invention, active keeper 10 is respectively formed with the first block arc with driving shaft
101 and second block arc 11, wherein,
Two are formed between first block arc 101 and the second block arc 11 and rotate idle stroke section, in two rotations
Elastic damping part is provided with idle stroke section, so that when driving shaft starts to rotate, one of elastic damping part is compressed simultaneously
Storage potential energy simultaneously discharges stored potential energy to driven shaft 200 to drive the rotating speed of driven shaft 200 gradually to increase simultaneously；And when from
When moving axis 200 stops operating, other in which elastic damping part is by driving shaft compression and while driving shaft is in rotating speed idle stroke section
Interior rotating speed is gradually reduced.
Due to be formed between the first block arc 101 and the second block arc 11 two rotate idle strokes section, and
Elastic damping part is provided with two rotation idle stroke sections, when driving shaft is rotated, driving shaft is rotating idle stroke section first
One section of idle running is inside carried out, and simultaneously compresses elastic damping part, so that cushioning effect is produced to driving shaft, and compressed simultaneously
Elastic damping part makes the rotating speed of driven shaft 200 slowly increase, and the transmittance process time of whole power and motion is more long, so that driven
Axle 200 is not in very big elastic-plastic deformation, effectively prevent the danger that driven shaft 200 is broken.And when driven shaft 200
When stopping operating, elastic damping part is compressed such that active rotating speed slowly declines by elasticity, so as to also effectively prevent master
Moving axis is broken because rotating stopping suddenly.
Used as further selection, elastic damping part is the second stage clip 50.
Used as further selection, active keeper 10 offers endoporus, and the first block arc 101 is formed in endoporus, main
In moving axis insertion endoporus, the head of driving shaft forms the second block arc 11.
Above example is only exemplary embodiment of the invention, is not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can make respectively in essence of the invention and protection domain to the present invention
