TRYK-TRÆK KÆDEAKTUATOR MED REDUCEREDE KÆDEVIBRATIONER

摘要

A push-pull chain actuator comprises a housing with a chain exit/entry opening and a sprocket arranged to engage a push-pull chain. The sprocket causes the polygon of the push-pull chain. The actuator comprises a first chain guide part for guiding said push-pull chain around the sprocket and a second chain guide part for guiding said push-pull chain at the correct angle between the chain exit opening and the sprocket. The second chain guide part is shaped and dimensioned to counteract the polygon effect. It is suggested that Fig. 2 is published with the abstract.
