<p>#CMT# #/CMT# The actuator has an electrical motor (85) for driving a pinion (86) in rotation according to an axis (X86). A movable trolley (88) moves according to a preset trajectory (D1) between two positions. An open chain (87) is engaged with the pinion, and an end (871) of the chain is connected with the trolley. A core (84) defines an elongated housing (L1) for guiding the chain and the trolley and another elongated housing (L2) for receiving length of a chain opposed to the trolley relative to the pinion. The housings are curved in a plane perpendicular to the axis of the pinion. #CMT#USE : #/CMT# Electric chain actuator for an opening i.e. door leaf, for a garage door. #CMT#ADVANTAGE : #/CMT# The housings are curved in a plane perpendicular to the axis of the pinion, so that the trajectory of the chain and the trolley are not forced into rectilinear movement so as to consider non-rectilinear movements for a part of the opening on which a moving part of the actuator relative to a body of the actuator is hanged and to limit the obstruction of the actuator. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a leaf door including an actuator. D1 : Preset trajectory L1, L2 : Elongated housings X86 : Axis 84 : Core 85 : Electrical motor 86 : Pinion 87 : Open chain 88 : Movable trolley 871 : End of open chain.</p> |
