The invention relates to a speed-controllable gravity drop winch with a built-in speed reducer. The built-in speed reducer is arranged in a winding drum, wherein an input end housing of the built-in speed reducer is fixed on a winch support; a transmission shaft is fixedly connected with an output end of the built-in speed reducer; the transmission shaft and an input shaft of the built-in speed reducer are coaxially arranged; the built-in speed reducer is provided with a front end housing and a speed reducer lower box body; a full-floating type internal expansion clutch is arranged on the transmission shaft; a bearing seat supports the transmission shaft through a first bearing; a brake drum outer ring is arranged outside the winding drum; an external expansion belt type brake is arrangedon the brake drum outer ring; and the external expansion belt type brake is arranged on the brake drum outer ring of the winding drum in a suspension and sleeving mode. The speed-controllable gravitydrop winch with the built-in speed reducer is compact in structure, small in size and safe and reliable to use; and the loading and unloading operation efficiency of hoisting machinery is improved, energy is saved, and the built-in speed reducer and the full-floating type internal expansion clutch can be simultaneously integrated in the winding drum to drive a heavy object to ascend and descend through a steel wire rope.

    本发明涉及一种内置减速器且速度可控的重力下降卷扬机,卷筒内设有内置减速器,内置减速器的输入端壳体固定在卷扬支座上,传动轴与内置减速器的输出端固联,且传动轴与内置减速器的输入轴同轴布置,内置减速器具有前端壳体和减速器下箱体,传动轴上装有全浮式内涨离合器,轴承座通过第一轴承支承传动轴,卷筒外设有制动鼓外圈,制动鼓外圈设有外涨带式制动器,且外涨带式制动器悬套于卷筒的制动鼓外圈。本发明结构紧凑,体积小;使用安全可靠;不仅提高起重机械的装卸作业效率,而且节约能源,可以实现内置减速器和全浮式内涨离合器同时集成于卷筒内通过钢丝绳驱动重物上升和下降。
