To solve the problem existing in the mechanical expanding shaft with screw-pairs and slope that the shaft diameter changes in small range while the screw rotates in large scale,the paper offers a new mechanical expanding shaft,which uses an Archimedean spiral tray to substitute the typical structure of screw-pairs and slope,absolutely solves the inconvenience problem in operating.
针对目前采用螺纹加斜面方式的各类机械式胀轴在使用中存在的向径变化极小而操作时旋转角度很大的问题,提出了一种新型的阿基米德螺线盘式机械式胀轴,它代替了螺纹加斜面方式的典型结构,彻底解决了以往机械式胀轴操作不方便的问题,该新型胀轴在电子产品生产线上是为主机提供卷状制品的供料设备。
