Technical Field

[0001] The utility model relates to the technical field of electric actuators, in particular to a high-strength outer shell of an electric actuator. Background Art

[0002] Electric actuator is a kind of mechatronic device, usually composed of motor, reducer, control system and actuator, etc. The actuator usually includes gear, worm gear, worm, lead screw, slider, etc., which are used to transmit power and change the output parameters such as position, speed and direction.

[0003] As an important part of the control system, electronic actuators are usually used to control valves to control the flow and direction of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. In order to ensure the smooth flow of the medium, the electronic actuator housing needs to have a certain strength. However, since electronic actuators are usually distributed in complex working environments, they are easily deformed by contact and extrusion, and the overall strength needs to be further improved.

[0004] And when working in a high temperature environment, the motor in the electronic actuator will be affected by the heat, but the motor is usually in a closed environment with poor heat dissipation, which affects the stability of the electronic actuator operation. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a high-strength outer shell of an electric actuator, which overcomes the deficiencies of the prior art and effectively solves the problems that the outer shell strength needs to be improved and the heat dissipation effect of the motor in the electronic actuator is poor.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A high-strength outer shell of an electric actuator comprises a shell, a reinforcement strip is welded to an outer wall of one side of the shell, an output frame is fixedly connected to the outer wall of the top of the shell by bolts, an output end shaft ring is arranged on the inner wall of the output frame, and a reinforcement sheet is welded between the output end shaft ring and the output frame;

[0008] A heat dissipation shell is welded on the outer wall of one side of the shell, and a fan is installed on the inner wall of the heat dissipation shell. A heat dissipation groove is opened on the inner wall of one side of the shell, and a ventilation groove is opened on the inner wall of one side of the shell.

[0009] Preferably, a motor compartment is provided on an outer wall of one side of the shell, and heat dissipation strips distributed at equal distances are welded to the outer wall of the motor compartment.

[0010] Preferably, the outer wall on the other side of the shell is fixedly connected with a cover plate by bolts.

[0011] Preferably, an input end shaft ring is provided on a side of the inner wall on the other side of the shell close to the cover plate.

[0012] Preferably, a transmission compartment is provided on the top outer wall of the shell body at the bottom of the output frame, and the input end shaft ring is connected to the interior of the transmission compartment.

[0013] Preferably, the outer wall on the other side of the shell is fixedly connected to the electric control compartment by bolts.

[0014] The beneficial effects of the utility model are:

[0015] 1. The high-strength outer shell of the electric actuator of this design is provided with reinforcement strips and reinforcement sheets on the outside of the shell and inside the output frame respectively. The strength of the outer wall of the shell can be increased by the lateral and longitudinal distribution of the reinforcement strips, and the strength of the output frame can be increased by connecting the output frame and the output end shaft ring with multiple reinforcement sheets at the same time, thereby improving the overall pressure resistance of the device and further improving the overall strength;

[0016] 2. The high-strength outer shell of the electric actuator designed in this paper adds a heat dissipation shell on the outside of the motor compartment. A fan can be installed inside the heat dissipation shell. With the cooperation of the heat dissipation groove and the ventilation groove, the fan can blow air to the outside and inside of the motor compartment at the same time, thereby reducing the temperature of the motor in time, avoiding the high temperature of the motor affecting the stability of the operation of the electronic actuator, and having a good heat dissipation effect.

[0023] In this embodiment, since the reinforcement strips 2 and the reinforcement sheets 5 are respectively provided on the outside of the shell 1 and inside the output frame 3, the strength of the outer wall of the shell 1 can be increased by utilizing the lateral and longitudinal distribution of the reinforcement strips 2, and the strength of the output frame 3 can be improved by simultaneously connecting the output frame 3 and the output end shaft ring 4 using multiple reinforcement sheets 5, thereby improving the overall compressive resistance of the device and further enhancing the overall strength.

[0025] In this embodiment, a heat dissipation shell 6 is added to the outside of the motor compartment 10, and a fan 7 can be installed inside the heat dissipation shell 6. With the cooperation of the heat dissipation groove 8 and the ventilation groove 9, the fan 7 can blow air to the outside and inside of the motor compartment 10 at the same time, thereby reducing the temperature of the motor in time, avoiding the high temperature of the motor from affecting the stability of the operation of the electronic actuator, and achieving good heat dissipation effect.

[0026] Reference Figure 3 A motor compartment 10 is disposed on the outer wall of one side of the housing 1, and heat dissipation strips 11 distributed at equal distances are welded to the outer wall of the motor compartment 10.

[0027] Reference Figure 1 The outer wall on the other side of the shell 1 is fixedly connected with a cover plate 12 by bolts.

On this basis, the output frame 3 and the output end shaft ring 4 are connected at the same time using multiple reinforcement sheets 5 to improve the strength of the output frame 3. In a high temperature environment, part of the heat of the motor will remain in the motor bin 10, and part of the heat will be absorbed by the heat dissipation strips 11.
