The invention relates to a gear box for a constant-tension winch, a box body of the gear box is formed by welding steel plates, and a box body cover plate is fixed on the box body of the gear box through screws and gaskets. A large gear and a small gear of which the outer teeth are completely meshed are arranged in a cavity of the gear box; the two ends of each gear are fixed through bearings respectively. A lifting motor and a constant tension motor are respectively arranged outside the gear box; inner teeth of the pinion are meshed with an output shaft of the constant tension motor; the inner teeth of the large gear and the outer ring of the backstop are fixed through screws; an inner ring of the backstop is meshed with an output shaft of the lifting motor; an output shaft of the large gear is meshed with the speed reducer. The backstop has the characteristic of only one-way operation; when the output shaft of the lifting motor rotates in the forward direction, the inner ring of the backstop is driven to rotate, the outer ring and the inner ring of the backstop are synchronous, then the large gear is driven to rotate, and the winch takes up a rope and lifts goods. The device is simple in structure, economical, practical, convenient to install and maintain and high in reliability.

    本发明涉及一种恒张力绞车用齿轮箱,齿轮箱箱体由钢板焊接而成,箱体盖板通过螺钉和垫圈固定在齿轮箱箱体上。齿轮箱腔体内装有外齿完全啮合的大齿轮、小齿轮各一个;每个齿轮两端分别由轴承固定。齿轮箱外部分别安装起升马达、恒张力马达;小齿轮的内齿与恒张力马达的输出轴啮合;大齿轮的内齿和逆止器的外圈通过螺钉固定;逆止器的内圈与起升马达的输出轴啮合;大齿轮的输出轴和减速机啮合。逆止器有着只能单向运转的特性;起升马达的输出轴正向旋转时带动逆止器内圈旋转,逆止器的外圈与内圈同步,继而带动大齿轮旋转,绞车收绳并起吊货物。本发明结构简单,经济实用,便于安装维修,可靠性高。
