The transmission function of plum blossom elastic coupling

　　The plum blossom elastic coupling is mainly composed of three parts, namely the left and right half couplings and the plum blossom elastic body. The plum blossom elastic body is located in the middle of the left and right half couplings, which plays a meshing transmission and effectively outputs power. Can play a very good cushioning effect.
　　The quincunx-shaped elastic coupling uses a drum-shaped quincunx-shaped elastic body to be placed between the two half-coupling claws to realize the elastic connection of the two half-couplings.When the coupling is working, the drum-shaped elastic petals embedded between the driving and driven pawls in the direction of rotation can fully contact the paws of the half-coupling, which compensates for the deviation of the elastomer petal pitch and the convexity of the half-coupling. The claw distance error of the claws makes the elastic body and the coupling uniformly stressed, which improves the load-bearing capacity of the coupling. At the same time, since the cross section of the elastic flap is drum-shaped, the angular displacement compensation of the coupled shaft is greatly improved.
