Patent attributes
The invention relates to reduction gearing (10) for an electrically driven actuator for controlling a gaseous or liquid volumetric flow (98), in particular in the fields of heating, ventilation and air conditioning technology and fire and smoke protection, said reduction gearing (10) being modular. Said gearing consists essentially of primary gearing (12) containing at least one drive motor (20) and secondary gearing (14) with a power take-off (36). In addition, a self-limiter (16) is integrated into the primary gearing (12). The gearing modules (12, 14) are detachably interconnected, in particular various secondary gearing mechanisms (14) can be used for the primary gearing (12). The inventive reduction gearing (10) is advantageously complemented in particular by a modular actuator comprising a modular housing, a modular electronics system (38), a sensor and COM module and a coupling module (28).
