The function of the coupling in the connection device is to connect the two axises and transfer the movement. Due to the particular structure of the laminated coupling, the main function of the coupling is to compensate the misalignment generated in the operation process of the axises. In this paper, a new type of laminated structure coupling - four-hole Joint Bearing laminated coupling is proposed. By using this coupling the shaft misalignment compensation ability between the two axises is improved from 1.0 ° ~ 1.5 ° to 4 ° ~ 6 °. Classical mechanics method and ANSYS finite element analysis are employed to analyse 3 different sizes of joint couplings, respectively. From the analysis the position of the maximum stress and the shaft misalignment compensation ability of each kind of coupling which provide the theory basis for the design of the new type of the coupling can be obtained.
