Compound Intermittent Mechanism

抄録

Many mechanisms for imparting intermittent motion have already been devised. Among these mechanisms, the Geneva mechanism is most commonly used, because of its simplicity. However, it is inferior to a barrel cam mechanism from the view-point of dynamic characteristic.Therefore, to remove this fault, the author has tried to rotate the driving shaft of the Geneva mechanism nonuniformly, and prposed a new intermittent mechanism which is named "compound intermittent mechanism".In this paper, the characteristic of the compound intermittent mechanism has been discussed theoretically. The paper is summarized as follows. The compound intermittent mechanism is superior to the Geneva-gear train, which is commonly used, in the next points. (1) (Dwell period./index period) can be easily changed. (2) The indexing angle is precise. (3) The fluctuating input torque is small.
