The invention relates to the field of winches, in particular to a winch for an underground coal mine. The winch comprises a permanent magnet direct drive synchronous motor, a gear shaft and a windingdrum which are arranged on a winch base. The permanent magnet direct drive synchronous motor is rotationally connected with the gear shaft through a coupler, and a large gear ring is mounted at one end of the winding drum; the gear shaft is rotationally connected with the large gear ring fixed at one end of the winding drum through a carrier gear; and the permanent magnet direct drive synchronousmotor acts, and power is transmitted to the winding drum through the gear shaft to drive the winding drum to work. The winch is simple in structure, low in early-stage equipment investment, small in arrangement space, stable and reliable in later-stage operation and convenient to maintain.
本发明涉及绞车领域,尤其涉及一种煤矿井下用绞车,包括设置在绞车底座上的永磁直驱同步电机、齿轮轴、卷筒,永磁直驱同步电机通过联轴器与齿轮轴转动连接,卷筒一端安装有大齿圈,齿轮轴通过过桥齿轮与固定在卷筒一端的大齿圈转动连接;永磁直驱同步电机动作,动力由齿轮轴传递至卷筒进而驱动卷筒工作;本发明结构简单,前期设备投资小而且布置所需空间小,后期运行平稳可靠且维护方便。
