The invention discloses an overload protection device for a winch. The overload protection device for the winch comprises an input shaft, an output shaft and a clutch assembly, wherein the input shaftis provided with a first transmission end; the output shaft is provided with a second transmission end; the clutch assembly is provided with a first clutch piece and a second clutch piece; the firstclutch piece is arranged at the first output end of the input shaft, so that the first clutch piece can rotate along with the input shaft; the second clutch piece is arranged at the second transmission end of the output shaft, so that the second clutch piece can rotate along with the output shaft; and the first clutch piece and the second clutch piece are clamped with each other in a separable mode. Therefore, under the condition that the output shaft is subjected to an overlarge load, the first clutch piece and the second clutch piece can jump off to cut off the power transmission relation between the input shaft and the output shaft, so that the overall structure is protected.

    一种用于绞盘机的过载保护装置,其包含有一根输入轴、一根输出轴及一个离合组件。输入轴具有一个第一传动端,输出轴具有一个第二传动端,离合组件具有一个第一离合件及一个第二离合件,第一离合件设于输入轴的第一输出端,使第一离合件能随输入轴一起转动,第二离合件设于输出轴的第二传动端,使第二离合件能随输出轴一起转动,第一离合件与第二离合件之间以可分离的方式相互卡接。以此,在输出轴受到过大负载的情况下,第一离合件与第二离合件会产生跳脱以切断输入轴与输出轴之间的动力传输关系,使整体结构获得保护效果。
