SYSTEM AND APPARATUS FOR DECOUPLING AN ELECTRO-MECHANICAL ACTUATOR FROM A PORTION OF A LINKAGE

摘要

In various embodiments, a drive system with a motor rotary actuator driven linkage and an override system is provided. The override system may be a manually actuated override system that, in response to a power loss or outage, is configured to disengage one or more links of drive system 100 from the electric motor rotary actuator, allowing the disengaged link to be moved and/or repositioned. Moreover, drive system 100 and, more specifically, the override system may be configured to restore normal operation to the disengaged link in response to power being restored (i.e., by reengaging the link).

主权项

1. A drive system, comprising:
an electromechanical rotary actuator including an output shaft; a first link operatively coupled to the output shaft and configured to actuate a first mechanism in response to being driven in a first direction; a second link operatively coupled to the first link via a pin and configured to actuate a second mechanism in response to being driven in a second direction; a third link operatively coupled to the first link and the second link via the pin; and a toggle arm pivotally coupled on the third link, the toggle arm operatively coupled to the pin and configured to actuate the pin between an operating position and an override position in response to actuation input.
