Abstract

The invention discloses an electric actuator. The electric actuator comprises a shell (1), an upper box plate (2), a support (3) , a direct-current brushless motor (4), an upper cover (5), a wiring cover (6), a circuit plate (7), a gear train (8), a main shaft (9), a valve rod connecting part (10), an electromagnetic coil (11), a manual clutch (12) and a manual wrench (13). According to the electric actuator, a secondary gear in the gear train is used as a driving gear and a manual gear as well, so that structure design of the electric actuator is greatly simplified, and operation is simple; the electromagnetic coil sleeves the outer edge of a boss hole, so that automatic power-off during manual operation and automatic power-on after the manual operation is finished are achieved, and the manual operation is simplified; overload protection of the secondary gear and other components in the electric actuator can be realized through design of the manual clutch; and the electric actuator has the advantages of being simple in structure, reasonable in design, convenient to use, low in manufacturing cost and the like.

Description

technical field [0001] The disclosure of the present invention relates to the technical field of electromechanical control, in particular to an electric actuator. Background technique [0002] An electric actuator is a driving device that can provide linear or rotary motion. It uses a certain driving energy and works under the action of a certain control signal. The actuator uses liquid, gas, electricity or other energy and passes through a motor, cylinder or Other devices convert this into actuation. [0003] When the electric actuator is actually used, if an emergency occurs, emergency manual operation is required. The existing actuator adopts an AC motor, which has a large holding force. In order to realize emergency manual operation, it is necessary to set up another manual gear on the basis of the existing transmission gear train, which is specially used for emergency manual operation. The manual gear meshes with the primary gear in the gear train, and when using the ...
