Coupling device of execution motor and coaxiality adjusting method thereof

The invention belongs to the field of ship gun servo systems, and relates to a coupling device of an execution motor and a coaxiality adjusting method thereof. In order to solve the technical problemsin the prior art, the coupling device of the execution motor comprises the execution motor, a cross axle universal joint coupling arranged at the upper part of the execution motor, and a base coupling part at the bottom of the execution motor. Through rough adjustment and fine adjustment of a shaft shoulder gap of the cross axle universal joint coupling, the advantage of high axial compensation quantity of the cross axle universal joint coupling is effectively used, so that the mounting coaxiality of the execution motor and a steering gear box can be effectively improved, the operation is stable, and the shaking problem of the steering gear box is solved. 本发明属于舰炮随动系统领域，涉及一种执行电机的联轴装置及其同轴度调节方法。为解决现有技术问题，本发明提供一种执行电机的联轴装置，其包括执行电机、设置在执行电机上部的十字轴万向节联轴器、以及执行电机底部的底座联轴部，通过对十字轴万向节联轴器轴肩间隙的粗调，精调，有效利用十字轴万向节联轴器轴向补偿量大的优点，能够有效改善执
