Fast attachment open end direct mount damper and valve actuator

A damper and valve actuator assembly comprising:

• a housing;
• a rotatable clamping gear including a clamp disposed within the housing, the clamp configured to attach onto one of a damper assembly jackshaft operable to control the position of one or more damper blades, a valve stem or valve linkage shaft each operable to control a valve position, wherein the clamp is accessible via a slotted opening which is unobstructed at one end;
• a threaded rod for operating the opposing members of the clamping device toward or away from each other;
• a motor configured to rotate the clamping device within the housing via a gear train meshed with the clamping gear;
• and
• a control module coupled to the motor and configured to control the damper and valve
• actuator assembly,
• wherein the clamping gear is asymmetrical with an open ended shape that coincides with the shape of the open ended slot, and
• wherein the housing further includes a rod slot through which a portion of the rod extends externally through the housing, the clamping gear includes a first hole to receive the rod, and the rod is configured to move along the rod slot when the clamping device is rotated by the motor.

A damper and actuator assembly comprising:

• a damper having at least one damper blade and a jackshaft to control the position of the damper blade;
• and a damper actuator attached to a support structure for the damper, the damper actuator comprising:
• a housing having at least one tab with an opening for a fastener such that the housing may be removably attached to a support structure of the damper;
• a rotatable clamping gear including a clamping device disposed within the housing, the clamping device configured to attach onto the jackshaft of the damper, where rotation of the jackshaft is operable to control the position the damper blade, wherein the clamping device is accessible via an open-ended slot;
• a threaded rod for operating the opposing members of the clamping device toward or away from each other;
• a motor configured to rotate the clamping device within the housing via a gear train meshed with the clamping gear;
• and
• a control module coupled to the motor and configured to control the damper actuator assembly,
• wherein the clamping gear is asymmetrical with an open ended shape that coincides with the shape of the open ended slot, and
• wherein the housing further includes a rod slot through which a portion of the rod extends externally through the housing, the clamping gear includes a first hole to receive the rod, and the rod is configured to move along the rod slot when the clamping device is rotated by the motor.
