In view of this, the present invention provides a novel coupling for a universal shaft, which includes a first flange, a second flange and a connecting bolt, wherein n first bolt holes are formed in the first flange along a circumferential direction of a flange plate, n second bolt holes are formed in the second flange along the circumferential direction of the flange plate, the connecting bolt penetrates through the first bolt holes and the second bolt holes to connect the first flange and the second flange, a positioning groove is formed in a side edge of the first flange, a positioning block is formed in a side edge of the second flange, an opening width of the positioning groove is greater than a maximum width of the positioning block, and the positioning block is movably disposed in the positioning groove.
Furthermore, the positioning groove is characterized by further comprising a limiting block, and the limiting block is arranged in the positioning groove through a limiting bolt.
Further, still include the blotter, the blotter side is equipped with the breach, the circumferencial direction of blotter is equipped with a plurality of n third bolt holes.
Further, the first flange is provided with a first shaft hole, the second flange is provided with a second shaft hole, and the cushion pad is provided with a third shaft hole.
Furthermore, the positioning grooves and the positioning blocks are of right-angle structures.
Further, the number of n is: n is more than or equal to 1 and less than or equal to 6.
Compared with the prior art, the novel coupler for the universal shaft has the beneficial effects that: the first flange and the second flange are quickly positioned and connected through the positioning grooves and the positioning blocks, the bolt connection can be directly installed, and the assembly efficiency is greatly improved; the buffer cushion can slow down the axial impact of shaft coupling, has prolonged the life of shaft coupling.
