ACTUATOR FOR ELEVATOR DOORS, ELEVATOR DOOR ARRANGEMENT INCLUDING SAME AND METHODS |
摘要 |
A double door actuation system is provided. The actuation system includes a base frame, a drive motor, first and second guide rails and a pair of rail support arrangements. The drive motor is mounted to the base frame and includes a pinion gear rotatable about an axis of rotation. The guide rails include opposed raceways and a gear rack. The gear rack engages the pinion gear opposite sides such that the pinion gear simultaneously drives the guide rails in opposite directions parallel to a drive axis. The rail support arrangements are mounted to the base frame and support guide rails. The rail support arrangements maintain a substantially constant lateral location of the guide rails in a direction perpendicular to both the drive axis and axis of rotation to maintain a substantially constant mesh between the pinion the gear racks.
