ZL type elastic pin coupling and shaft connection is not strong in the case of easy loosening, and the torque will be small, and the buffer seismic performance is not good, affecting the reliability of the coupling, shorten the service life. Then the new ZL type elastic pin coupling to solve the above technical problems, to provide a good buffer shock resistance, large transfer torque, long service life of the coupling.

ZL type elastic pin coupling is composed of an inner sleeve and a coat and an elastic pin, and the inner sleeve is arranged in the coat, the outer wall of the inner sleeve and the inner wall of the coat are provided with at least one semi-circular groove which can butt into a cylindrical hole, the cylindrical hole is provided with an elastic pin, the center of the inner sleeve is provided with a shaft jack, the shaft jack wall is provided with a groove along the axis, One end of the outer wall of the coat is provided with a connecting disk, and the connecting disk is provided with a connecting hole. ZL type elastic pin coupling more torque transfer, longer service life; Good cushioning and shock absorption, compensate the deflection and displacement of two axes, high reliability.

The elastic pin in the new ZL type elastic pin coupling is made of elastic material, which can play the role of cushioning and damping. At the same time, the elastic deformation of the elastic pin can compensate the deflection and displacement of the two axes, and strengthen the reliability of the coupling.
