Description

Technical Field

[0001] The utility model relates to the technical field of couplings, and more specifically to a high-buffer coupling with stable connection. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part. They rotate together during the transmission of motion and power and do not disengage under normal circumstances. There are many types of couplings available, including the plum blossom coupling, which has a rubber ring installed between the two claws to buffer the axial force. It is suitable for drive shafts that require forward and reverse adjustment, such as screw drives.

[0003] There are many ways to install the existing coupling on the shaft body. There is a snap-on type, which is directly snapped on the shaft body, and there is also a coupling that is divided into an upper and lower part. In this case, the upper and lower parts are fixed by bolts. This installation is more convenient to operate than the snap-on type. However, during the installation process, the upper and lower parts lack a positioning mechanism, which requires manual auxiliary positioning when aligning the upper and lower threaded holes, and bolt installation is more inconvenient.
