Abstract

A rotary actuator includes a connector housing with a hollow tube, a separate motor housing clipped to one side of the connector housing, and a separate gear and sensor housing clipped to an opposed side of the connector housing. At least a first gear and a first gear carrier are located within the interior of the hollow tube. A motor shaft extends from the motor through the connector housing into the tube and into engagement with the first gear. A sensor is seated on an exterior surface of the hollow tube and a magnet is housed in the interior of the first gear carrier. The sensor is adapted to change changes in the magnetic field generated by the magnet in response to movement of the magnet.

First claim

We claim:

1. A rotary actuator comprising:
a connector housing including a frame;
a separate motor housing secured and extending outwardly from a first side of the frame of the connector housing and defining an interior adapted to house a motor; and
a separate gear and sensor housing secured and extending outwardly from a second side of the frame of the connector housing opposed to the first side of the frame of the connector housing and defining an interior adapted to house a plurality of gears, a sensor, and an output shaft; and
clips on the respective motor housing and the gear and sensor housing for securing the motor housing and the gear and sensor housing to the frame of the connector housing.

2. The rotary actuator of claim 1 further comprising a hollow tube in the interior of the gear and sensor housing, the sensor being seated on the tube and the plurality of gears being located in the interior of the tube.

3. A rotary actuator comprising:
a connector housing including a frame;
a separate motor housing secured and extending outwardly from a first side of the frame of the connector housing and defining an interior adapted to house a motor; and
a separate gear and sensor housing secured and extending outwardly from a second side of the frame of the connector housing opposed to the first side of the frame of the connector housing and defining an interior adapted to house a plurality of gears, a sensor, and an output shaft;
wherein the connector housing includes a hollow tube extending outwardly from the second side of the frame of the connector housing and into the interior of the gear and sensor housing and the sensor is seated on the tube of the connector housing and the plurality of gears are located in the interior of the tube of the connector housing.

4. A rotary actuator comprising:
a connector housing including a frame;
a separate motor housing secured and extending outwardly from a first side of the frame of the connector housing and defining an interior adapted to house a motor; and
a separate gear and sensor housing secured and extending outwardly from a second side of the frame of the connector housing opposed to the first side of the frame of the connector housing and defining an interior adapted to house a plurality of gears, a sensor, and an output shaft; and
wherein the plurality of gears comprises first and second sets of gears mounted on first and second gear carriers respectively, the second gear carrier also defining an interior adapted to receive a magnet.

5. The rotary actuator of claim 4 further comprising an internal drive arm located in the aperture defined in the second carrier.

6. The rotary actuator of claim 5 wherein the internal drive arm includes a plurality of arms adapted to be located in respective grooves defined in the second gear carrier.
