The invention discloses a full-rotation steering oar transmission chain spline connection structure. The structure comprises a driving bevel gear, a thrust bearing, an input shaft spacer ring and a positioning ring which are arranged outside an input shaft in a sleeving mode, and a driven bevel gear, a self-aligning bearing and an output shaft spacer ring which are arranged outside an output shaft in the sleeving mode, wherein the driving bevel gear is connected with the input shaft through an involute spline, and the driven bevel gear is connected with the output shaft through an involute spline; the driving bevel gear is meshed with the driven bevel gear; one end of the input shaft spacer ring is in clearance fit with a first spigot in one end of the driving bevel gear, and the other end of the input shaft spacer ring is attached to a shaft shoulder of the input shaft; one end of the positioning ring is in clearance fit with a second spigot in the other end of the driving bevel gear, and the other end of the positioning ring is matched with a thrust bearing set; and one end of the output shaft spacer ring is in clearance fit with a first groove in one end of the driven bevel gear, and the other end of the output shaft spacer ring is attached to a shaft shoulder of the output shaft. According to the design, through the input shaft spacer ring and the positioning ring, splines are prevented from bearing bending moment, the reliability of a transmission chain is improved, and the assembly difficulty is reduced.

    一种全回转舵桨传动链花键连接结构,包括均套设在输入轴外的主动锥齿轮、推力轴承、输入轴隔环、定位环,以及均套设在输出轴外的从动锥齿轮、调心轴承、输出轴隔环,主动锥齿轮与输入轴、从动锥齿轮与输出轴均通过渐开线花键连接,主动锥齿轮与从动锥齿轮相啮合,输入轴隔环的一端与主动锥齿轮一端上的第一止口间隙配合、另一端与输入轴轴肩相贴合,定位环的一端与主动锥齿轮另一端上的第二止口间隙配合、另一端与推力轴承组相配合,输出轴隔环的一端与从动锥齿轮一端上的第一凹槽间隙配合、另一端与输出轴的轴肩相贴合。该设计通过输入轴隔环、定位环不仅避免了花键承受弯矩,提高了传动链的可靠性,而且降低了装配难度。
