Drive system for intermittent rotation output

Abstract:

An intermittent drive system includes a rotatable output component, a rotating input component with a driving engagement element, a synchronizing ring and a decoupling ring. The synchronizing ring is coupled to the output element to rotate therewith. The synchronizing ring has a driven engagement element configured to selectively engage with the driving engagement element. The synchronizing ring has an alignment feature configured to rotationally align the driving engagement element with the driven engagement element and has a decoupling feature configured to selectively disengage the driving engagement element from the driven engagement element. The decoupling ring is selectively coupled to the input component and has a decoupling feature configured to selectively engage the decoupling feature of the synchronizing ring. The driving engagement element engages the driven engagement element only when both the alignment feature is rotationally oriented to align the driving engagement element with the driven engagement element and the decoupling features are rotationally oriented to allow the driving engagement element to engage the driven engagement element.
