Abstract
The present invention relates to a tubular actuating mechanism (10) for roll-type closures, comprising an electric motor (30) and a gear reduction assembly (100) of the epicyclic gearing type comprising a rotatable sun gear (110), one or more rotatable planet gear (s) (130) and an outer ring gear (132).
Claims14
A tubular actuating mechanism for roll-type closures, comprising an electric motor and a gear reduction assembly of the epicyclic gearing type comprising a rotatable sun gear, one or more rotatable planet gear(s) and an outer ring gear,
- wherein said sun gear is a worm and a worm shaft is supported rotatably in a planet carrier and said one or more planet gear(s) interact(s) with the outer ring and turn(s) around a shaft that is supported in the rotatable planet carrier, thereby driving said planet carrier, and
- said gear reduction assembly is the first reduction stage of the mechanism coupled to the electric motor wherein said one or more planet gear(s) is a helical worm gear.
