The other set of mounting grooves 42 is rotatably connected to the spherical assembly 3.
[0026] According to the above structure, the mounting groove 42 is rotatably connected to the spherical assembly 3. When using the coupling, after the transmission shaft has rotated for a long time, the center may become misaligned. At this time, the connecting rod 43 can compensate for these displacements within a certain range, so that the coupling can still maintain good transmission performance under relative motion, ensure the stability of power transmission, avoid equipment damage or transmission failure due to shaft displacement, and also play a certain role in buffering and shock absorption. It can absorb and disperse some vibration and impact energy, reduce the impact of vibration and impact on the connecting parts and the entire mechanical system, thereby reducing equipment wear and fatigue damage and extending the service life of the equipment.
