The invention discloses a large-tonnage worm and gear winch and belongs to the technical field of engineering machinery, the large-tonnage worm and gear winch comprises a worm and a worm gear which are matched with each other, the worm is connected with the output end of a hydraulic motor through a connecting shaft, a one-way brake for preventing the worm from rotating reversely is arranged at the end, away from the hydraulic motor, of the worm, and the worm gear is connected with a transmission shaft. The transmission shaft penetrates through the middle of the winding drum, a speed reducer is installed outside the worm gear, and a clutch is arranged at the end, away from the worm gear, of the transmission shaft. A simple one-way brake mechanism is additionally arranged at the worm end, a large lead angle can be used in worm gear and worm transmission, and therefore the transmission efficiency of the worm gear and worm transmission is improved. Therefore, the winch is large in bearing capacity and high in transmission efficiency, has self-locking performance, and further has the advantages of a worm and gear transmission device.

    本发明公开了大吨位蜗轮蜗杆绞盘,属于工程机械技术领域,包括相互匹配的蜗杆和蜗轮,蜗杆通过连接轴与液压马达的输出端相连接,所述蜗杆远离液压马达的一端部设置阻止蜗杆反转的单向制动器,所述蜗轮连接传动轴,所述传动轴贯穿设置在卷筒的中部,蜗轮的外部安装减速器,所述传动轴远离蜗轮的一端部设置离合器。本发明在蜗杆端增加了简单的单向制动机构,可以在蜗轮蜗杆传动上使用较大的导程角,从而增加其传动效率。故该绞盘在承载力大、传动效率高的同时,又具备自锁性,另外还兼有蜗轮蜗杆传动装置本身的优点。
