Electric actuator

An electric actuator, comprising:

• a housing;
• an electric motor comprising a wound stator and a rotor mounted on a rotor shaft;
• a printed circuit for powering the stator and controlling the motor;
• an intermediate plate;
• a mechanical reduction gear driven by the rotor and formed by toothed wheels mounted on axes;
• a cover;
• and
• two centering pins;
• the housing defining a first cavity in which the stator is housed, and the housing configured to guide the rotor shaft on a first end;
• the printed circuit being housed in the first cavity above the stator;
• the intermediate plate being situated above the printed circuit;
• the cover defining a second cavity and configured to guide one end of the axes of the mechanical reduction gear, the cover being located above the intermediate plate;
• and
• the intermediate plate being configured to guide the other end of the rotor shaft and the other ends of the axes of the mechanical reduction gear;
• wherein,
• in the first cavity of the housing, there is a first pair of centering holes receiving the two centering pins;
• in the intermediate plate, there is a second pair of centering holes receiving the two centering pins;
• in the cover, there is a third pair of centering holes receiving the two centering pins;
• the intermediate plate is in contact with the housing and the cover solely on support surfaces located around the centering holes;
• and
• the housing comprises a single sealing gasket positioned at the interface between the housing and the cover.
