Description
Technical Field
The utility model belongs to the technical field of electric actuator, specifically speaking especially relates to a part gyration electric actuator moment mechanism.
Background
Electric actuators are increasingly used. While the industries such as power plants, petrochemical industry, and water conservancy facilities increasingly emphasize automatic industrial control, electric actuators are increasingly applied to the industries. Meanwhile, the requirements on the use and various aspects of the electric actuating mechanism are further improved, the electric actuating mechanism is applied to various key positions, and the reliability and flexible application of the electric actuating mechanism also meet higher requirements.
The electric actuating mechanism has the advantages of convenient energy source taking, high signal transmission speed, long signal transmission distance and the like, so as to facilitate centralized operation and control, and has high precision and relatively high sensitivity.
The electric actuating mechanism is internally provided with a moment mechanism, the existing moment mechanism is relatively complex in structure and large in size, and the internal space of a part of the rotary electric actuating mechanism is narrow.
Disclosure of Invention
In order to solve the problem, the utility model discloses a part gyration electric actuator moment mechanism.
The utility model discloses a realize through following technical scheme:
the utility model provides a part gyration electric actuator moment mechanism, includes micro-gap switch, cam, mounting panel, micro-gap switch connect in the cam, micro-gap switch and cam are fixed the mounting panel top, the torque transmission shaft is passed at the cam center, torque transmission shaft one end is connected with the crank axle, the other end of crank axle is connected in the worm, the worm is installed on part gyration electric actuator body and one end stretches out outside the body.
The mounting plate is fixed on the shell of the partial rotary electric actuator body.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses part quantity and whole size have been simplified to the maximize, can be used in the narrow and small space of part gyration electric actuator inside.
Drawings
FIG. 1 is a schematic cross-sectional view of the structure of the present invention;
fig. 2 is a schematic side view of the structure of the present invention.
In the figure: 1. a microswitch; 2. a cam; 3. mounting a plate; 4. a torque transmission shaft; 5. a crank shaft; 6. A worm; 7. a rotary electric actuator body; 8. a housing.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1 of the attached drawings of the specification, a torque mechanism of a partially-rotating electric actuator comprises a microswitch 1, a cam 2 and a mounting plate 3, wherein the microswitch 1 is connected to the cam 2, the microswitch 1 and the cam 2 are fixed above the mounting plate 3, the center of the cam 2 passes through a torque transmission shaft 4, one end of the torque transmission shaft 4 is connected with a crank shaft 5, the other end of the crank shaft 5 is connected to a worm 6, the worm 6 is arranged on a partially-rotating electric actuator body 7, and one end of the worm 6 extends out of the partially-rotating electric actuator body 7.
The mounting plate 3 is fixed to a housing 8 of the partially-pivoting electric actuator body 7.
The use principle is as follows:
when the output shaft is subjected to a certain torque, the worm rotates and also generates axial displacement to drive the crank shaft to act, the torque transmission shaft and the cam are driven to press the microswitch when the crank shaft acts, the power supply of the motor is cut off, and the motor stops rotating, so that the output torque of the electric actuating mechanism is controlled, and the purpose of protecting the electric valve is achieved.
The utility model discloses part quantity and whole size have been simplified to the maximize, can be used in the narrow and small space of part gyration electric actuator inside.
In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
