The invention discloses a winding drum with a built-in motor and an external speed reducer. The winding drum comprises the motor, a motor connecting frame, a left supporting seat, a right supporting seat, a winding drum shell and the quasi-planetary speed reducer. Wherein the motor connecting frame, the motor, the connecting flange and the wheel train supporting frame form a penetrating type main shaft which is arranged in the winding drum shell and supported between the left supporting seat and the right supporting seat; the quasi planetary reducer comprises a coupler, a center wheel, an idle wheel set, an inner gear ring, a gear train supporting frame, a plurality of bearings and a plurality of sealing pieces. Left and right supporting discs are arranged at the two ends of the winding drum shell and installed on the penetrating type main shaft. The motor is internally arranged, the axial size of the winding drum is shortened, and the roadway and chamber excavation cost is reduced; the quasi-planetary reducer reduces the size of the motor and increases the gap between the motor and the winding drum shell, so that heat dissipation is facilitated; and the speed reducer is externally arranged and is detachably designed, so that the quasi planetary speed reducer can be quickly detached and is convenient to maintain. The winding drum with the built-in motor and the external speed reducer has the advantages of being good in heat dissipation performance, simple in structure, short in axial distance, convenient to install, high in adaptability and the like.
本发明公开了一种内置电机和外置减速器的卷筒,它包括电机、电机连接架、左右支承座、卷筒壳体和准行星减速器;其中电机连接架、电机、连接法兰与轮系支承架组成贯穿式主轴内置于卷筒壳体,支撑在左、右支承座之间;准行星减速器包括联轴器、中心轮、惰轮组、内齿圈、轮系支承架及多个轴承和密封件;卷筒壳体两端设左右支承盘,安装于贯穿式主轴上。电机内置,卷筒轴向尺寸缩短,巷道和硐室开掘成本降低;准行星减速器使电机体积减小,电机与卷筒壳体间隙增大,便于散热;减速器外置且可拆卸式设计,可将准行星减速器进行快速拆卸,便于维护。内装电机和外置减速器的卷筒具有散热性好、结构简单、轴向距离短、安装方便、适应性强等优点。
