Motorized gear and coupling system
First Claim
1. A gear system comprising:
- a drive shaft;
a worm gear;
a coupling integral with the worm gear, the coupling comprising;
a set screw;
a bore for receiving the set screw; and
an opening for receiving the drive shaft; and
wherein the drive shaft is removably secured within the opening by the set screw;
a planetary gear in rotational engagement with the worm gear; and
a motor connected with and configured to rotate the drive shaft.

Abstract
A system for controlling airflow in a plenum, that comprises a worm gear and planetary gear that are removably coupled to a worm shaft and planetary shaft, respectively. The planetary shaft controls the movement of a damper between an open position permitting maximum airflow through the plenum, and a closed position restricting airflow through the plenum. A motor or gear-motor is positioned at the plenum for driving the worm shaft. The motor is controlled by a remotely located controller that includes a power supply for operating the motor. The controller is connected to the motor through a cable with a detachable electrical connection between the cable and the controller. Alternatively, the movement of the damper is controlled by a drive shaft, which connects the motor or gear motor directly to the damper without intervening gearing. The motor is positioned in the airflow of the plenum. The cable may extend through the plenum to a diffuser or other opening in the plenum for connection to the controller, or may exit through a hole formed in the plenum.
