[0020] Below, the utility model is further described in conjunction with the accompanying drawings.
[0021] Reference Figure 1 and Figure 2 This embodiment includes a reducer connecting plate, an outer sleeve, an inner sleeve, an active cross structure, a driven cross structure, an axial telescopic spline shaft, an axial output spline sleeve, etc.
[0022] The reducer connecting disc provides installation support for the entire coupling. The outer sleeve is installed on the reducer connecting disc, and the central axes of the two coincide. The active cross structure is installed inside the outer sleeve, and the driven cross structure and the axial output spline sleeve are both installed in the inner sleeve. The inner sleeve can slide axially in the outer sleeve. The axial telescopic spline shaft is respectively connected to the active cross structure and the driven cross structure. The axial output spline sleeve is located in the inner sleeve and connected to the driven cross structure. The reducer transmits the torque to the active cross structure through the reducer connecting disc and the outer sleeve, and the active cross structure transmits the torque to the driven cross structure through the spline shaft. Since the driven cross structure is connected to the axial output spline sleeve, the torque is finally output through the axial output spline sleeve.
[0023] The inner sleeve can slide axially in the outer sleeve, and the axial output spline sleeve can move freely on the plane of the inner sleeve, thereby realizing the axial expansion and contraction and the up, down, left and right displacement of the axial output spline sleeve.
[0024] Reference Figure 2 , the active cross structure 1 and the driven cross structure both include an inner ring and an outer ring located in the same plane; the central axes of the inner ring and the outer ring coincide, and the two are connected by two pin bearings located in the same straight line;
[0025] The outer ring of the active cross structure 1 is connected to the inner wall bearing of the outer sleeve 6 through a pin shaft 1, and the axial telescopic spline shaft 2 has the freedom to slide along the central axis of the inner ring;
[0026] The outer ring of the driven cross structure is fixedly connected to the inner end of the axial output spline sleeve 4; the axial telescopic spline shaft 2 is hinged to the inner ring of the driven cross structure through a hinge shaft.
