The embodiment of the invention provides a safety protection coupler for a marine full-rotation propelling device. The coupler comprises an elastic coupling, a middle floating shaft and a gear coupling which are coaxially arranged. The elastic coupling comprises a brake disc, a spherical bearing, a flange shaft and a rubber supporting piece which are coaxially arranged. The spherical bearing is used for fastening and connecting a hub of the propulsion motor shaft, the flange shaft is fastened and connected with the brake disc corresponding to the hub side of the propulsion motor shaft and correspondingly connected with the spherical bearing, and the rubber supporting piece is arranged between the hub of the propulsion motor shaft and the brake disc. When the rubber supporting piece is broken accidentally, other assemblies in the coupler can continue to rotate in the radial direction along with inertia to be decelerated, the safety protection effect is achieved, it is ensured that the coupler is not damaged, and normal operation can be achieved by replacing the rubber element after stopping. According to the method, the requirements of axial, radial and angular movement displacement generated by vibration during operation of the full-rotation propelling device are met.

    本发明实施例提供一种船用全回转推进装置安全防护联轴器,联轴器包括同轴设置的弹性联轴节、中间浮动轴和齿轮联轴节;弹性联轴节包括同轴设置的制动盘、球面轴承、法兰轴和橡胶支撑件;球面轴承用于紧固连接推进电机轴轮毂,法兰轴紧固连接制动盘对应推进电机轴轮毂侧并对应连接球面轴承,橡胶支撑件设置于推进电机轴轮毂与制动盘之间。当发生意外橡胶支撑件断裂时,联轴器中的其它组件又能随着惯性继续径向旋转而减速,起到了安全防护作用,确保不受损坏,停止后,对橡胶元件进行更换即可正常运转。该方法满足了全回转推进装置运行时震动产生的轴向、径向、角向移动位移的要求。
