Road is transmitted to the second half hub section 2 from the first half hub section 1.Coupler structure of the present invention has the characteristics that, first is that load is by each chain
Transmitting is shared on road, reduces the carrying size of components in each link；Second is that passing through the first film in power or movement transmittance process
Piece group 9-1 and secondary diaphragm group 9-2 mitigates impact, bit shift compensation effect since diaphragm group has, so that of the invention is whole
There is a shaft coupling good mitigation to impact and compensate displacement performance, especially preferable angular displacement compensation performance.And it is traditional
Diaphragm coupling is usually all single-link transmitting power and movement, i.e. power or movement is transmitted to diaphragm from one end of shaft coupling
Group, then it is transmitted to the output end of shaft coupling, this structure, once some part goes wrong in link, then power or movement were transmitted
Journey can interrupt at once or by extreme influence, to influence executing agency's working performance of shaft coupling connection.Shaft coupling of the present invention
Device structure tool is there are three link transmitting power or movement, the these problems for avoiding traditional diaphragm coupling from being likely to occur, therefore, tool
There is high reliablity feature.
Certainly, the above is only specific application example of the invention, protection scope of the present invention is not limited in any way.It removes
Outside above-described embodiment, the present invention can also have other embodiment.All technical sides formed using equivalent substitution or equivalent transformation
Case is all fallen within scope of the present invention.
