Reduction gearing for an electric actuator

Reduction gearing of an electrically operated actuator to control a gaseous or liquid volume flow in the field of heating, ventilation and air conditioning, fire or smoke protection, characterised in that a modularly constructed reduction gearing comprises a primary gear module with at least one drive motor and a secondary gear module with an output drive, wherein a self-lock is integrated, and said gear modules are connected together detachably, wherein the self-lock is formed as an externally activated switchable coupling, and wherein the self-lock in the area of the inner friction surface can be locked with a protruding trip cam.
