Detailed Description

To make the objects, technical solutions and advantages of the present invention clearer, the drawings of the present invention are combined to clearly and completely describe the technical solutions of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 5, the embodiment of the present application provides an eccentric coupling, which includes a first flange 10, a second flange 20, an expansion ring 30, an adjusting member 40, a transmission rod 50, and a third flange 60, where the first flange 10, the second flange 20, the expansion ring 30, and the adjusting member 40 are disposed in two sets, and the two sets of the first flange 10, the second flange 20, the expansion ring 30, and the adjusting member 40 are symmetrically disposed with respect to the third flange 60.

A first connecting hole 11 is formed in the center of the first flange plate 10, and a second connecting hole 21 is formed in the center of the second flange plate 20; the expansion ring 30 is connected with the first flange plate 10 in a split mode, the expansion ring 30 comprises an expansion wall 31 and a positioning ring 32, the expansion wall 31 is provided with an expansion opening, the expansion wall 31 can deform under stress, when the expansion ring 30 is connected with the first flange plate 10 and the second flange plate 20, the expansion wall 31 is located in the second connecting hole 21, and the positioning ring 32 is located in the first connecting hole 11; the osusu and the positioning ring 32 are integrally connected with the expansion wall 31, the adjusting member 40 penetrates through the second flange 20 and is connected with the first flange 10, the adjusting member 40 can move to lock the second flange 20 and the first flange 10, namely, when the adjusting member 40 moves in a locking mode, the second flange 20 and the first flange 10 can move close to each other, the adjusting member 40 has a preset locking position, and when the adjusting member 40 moves to the preset locking position, the expansion wall 31 is compressed in the second connecting hole 21, so that the expansion wall 31 can clamp a shaft in the expansion port. It should be understood that the preset locking position refers to a position where the movement of the adjusting member 40 is stopped, and since the expansion ring 30 is in the shape of a circular truncated cone, the expansion ring 30 can limit the movement of the second connecting hole 21 on the expansion wall 31, and at this time, the shaft can be clamped.

Through setting up split type connection between expansion ring 30 and the first ring flange 10 for when expansion ring 30 used for a long time and lead to damaging, only need change expansion ring 30 and need not change expansion ring 30 and first ring flange 10 together and change simply, it is with low costs.

Accordingly, when the adjusting member 40 is moved from the preset locking position, the expansion wall 31 can release the shaft located in the expansion port, and the shaft can be disengaged from the expansion wall 31. In this way, the shaft can be removed from the eccentric coupling.

In this embodiment, the expansion wall 31 is provided with a notch 311 from the top to the bottom, and the length of the notch 311 is smaller than the length of the expansion wall 31 from the top to the bottom. Thus, even if a part of the expansion wall 31 can be deformed by a force, the expansion wall 31 as a whole can be prevented from being damaged by the force.

Further, four notches 311 are provided, and four notches 311 are equiangularly provided on the expansion wall 31. The provision of four notches 311 makes it possible to obtain a better deformation effect of the expansion wall 31.

In order to ensure that the first flange plate 10 and the second flange plate 20 are fastened better and avoid the phenomenon that the two flange plates loosen to cause the coupling failure in the use process, a plurality of adjusting pieces 40 are arranged on the second flange plate 20, and the adjusting pieces 40 are arranged around the expansion wall 31. Specifically, the adjusting member 40 is a screw, and six screws are arranged around the periphery of the expansion wall 31 at equal angles.

To achieve the eccentric effect, the first flange 10 is arranged eccentrically to the third flange 60 and can rotate relative to the third flange 60. The rotation of the first flange plate 10 and the third flange plate 60 is realized through a transmission rod 50, the transmission rod 50 is arranged between the first flange plate 10 and the second flange plate 20, and two ends of the transmission rod 50 are respectively provided with a connecting rod which is respectively connected with the first flange plate 10 and the third flange plate 60 in a rotating manner.
