齿轮齿条直线差动行程增倍机构的设计与应用

Design and Application of Gear - Rack Straight Line Differential Doubling Mechanism

立体仓库堆垛机的货叉伸缩机构,要求在存物取货特定的狭小空间内双向伸缩,而且其刚度,动作行程,灵活性和可靠性都有特殊要求,是堆垛机结构设计的一个难点。笔者采用齿轮齿条传动的三层货叉直线差动行程增倍机构,合理解决了上述难题,在实践中获得了良好的实用效果。

The freight forklift expansion mechanism of three - dimensional storehouse stacker (special transporter for materials and supplies) needs a bi - directional expansion in an especially narrow space with special requirements for the rigidity, movement, flexibility and reliability , which is a difficulty in the structural design of stackers. This problem was solved by using the gear - rack straight line differential doubling mechanism of three - layer freight forklift and gaining a better practical effect in operation.
