US 2008/0173838 A1 · Actuator

Abstract

An actuator (10) and adapter (16,116), in particular with an electric motor (60), and a highly reduced gearing (48), is used for transmitting a torque to a continuous drive shaft (24) of at least one flap or at least one valve to control a gas or liquid volume flow. The adapter (16,116) which is used in particular in the sector of heating/ventilation/air-conditioning (HVAC), fire and space protection can be fitted in a manner which is locked against rotation in the radial direction to a frame or support of the actuated member. With the drive shaft (24,124) it forms a releasable frictional and/or positive connection. The actuator is preferably actuated by an electric actuator motor but also pneumatically, hydraulically or manually. The actuator (10) and adapter (16,116) can optionally be used as a bridging drive.

Dependent claims

Actuator and adapter, the actuator comprising

an electric motor,
a gearing output shaft
and a highly reduced gearing for transmitting a torque of the electric motor to said gearing output shaft
wherein the adapter is designed to transfer a torque from the gearing output shaft to a drive shaft of an actuated member,
said actuated member being at least one flap or at least one valve for controlling a gas or fluid volume flow, in particular in the sector of heating/ventilation/air-conditioning (HVAC), fire and area protection,
wherein
the adapter is configured to be fitted to a continuous drive shaft in a direction which is radially oriented with respect to the drive shaft
the adapter is further configured to form a releasable frictional and/or positive connection to said drive shaft and
the adapter is configured to be mounted on a frame or support of the actuated member in a manner which is locked against rotation.
