Rotary piston actuator anti-rotation configurations |
摘要 |
A rotary actuator includes a housing having an interior boundary that defines a central bore and has interior recesses, a chamber housing assembly disposed in the central bore and having an arcuate chamber, the arcuate chamber comprising a cavity, an exterior boundary of the chamber housing assembly having exterior recesses, each of the exterior recesses aligned with a respective one of the interior recesses, pins residing between the interior boundary and the exterior boundary, each of the pins mated to one of the exterior recesses and a corresponding one of the interior recesses to maintain an orientation of the chamber housing assembly with respect to the housing, a rotor assembly rotatably journaled in the chamber housing assembly and comprising a rotary output shaft and a rotor arm, and an arcuate-shaped piston disposed in the chamber housing assembly for reciprocal movement in the arcuate chamber. |

1. A rotary actuator comprising:
a housing comprising an interior boundary that defines a central bore and comprises interior recesses; a chamber housing assembly disposed in the central bore and comprising an arcuate chamber, the arcuate chamber comprising a cavity, a fluid port in fluid communication with the cavity, and an open end, an exterior boundary of the chamber housing assembly comprising exterior recesses, each of the exterior recesses aligned with a respective one of the interior recesses; pins residing between the interior boundary of the housing and the exterior boundary of the chamber housing assembly, each of the pins mated to one of the exterior recesses and a corresponding one of the interior recesses to maintain an orientation of the chamber housing assembly with respect to the housing; a rotor assembly rotatably journaled in the chamber housing assembly and comprising a rotary output shaft and a rotor arm extending radially outward from the rotary output shaft; and an arcuate-shaped piston disposed in the chamber housing assembly for reciprocal movement in the arcuate chamber through the open end, wherein a seal, the cavity, and the piston define a pressure chamber, and a portion of the piston connects to the rotor arm. |
