Description

Technical Field

[0001] The utility model belongs to the technical field of electric motors, and in particular relates to a three-phase asynchronous motor housing with good sealing performance. Background Art

[0002] A three-phase asynchronous motor is an induction motor that is powered by a 380V three-phase AC current. The rotor and stator rotating magnetic fields of this motor rotate in the same direction but at different speeds, resulting in a slip rate. Therefore, it is called a three-phase asynchronous motor.

[0003] The existing three-phase asynchronous motor has a poor sealing effect on the casing, and there are certain gaps between the casings. Therefore, external moisture and dust may enter the interior of the motor through the gaps between the casings, thereby damaging the internal parts of the motor, which not only affects the normal operation of the motor but also shortens the service life of the motor. In addition, the poor sealing effect of the motor casing may also cause harmful substances inside the motor to overflow, which may cause harm to the user. Utility Model Content

[0012] As a further description of the above technical solution:

[0013] A plurality of travel grooves are provided on one side of the inner wall of the sliding groove, and the other side of the travel grooves is communicated with the inner wall of the first sealing groove.

The inner wall of the first sealing groove 301 is slidingly connected to the first fixing ring 303, and one side of the first fixing ring 303 is connected to multiple first springs 304. The other end of the first spring 304 is connected to the inner wall of the first sealing groove 301, and the other side of the first fixing ring 303 is connected to the first sealing gasket 302. The outer wall of the first sealing gasket 302 is slidingly connected to the inner wall of the first sealing groove 301, and the outer wall of the first sealing gasket 302 is in contact with the inner wall of the second sealing groove 305.

[0032] The specific implementation is as follows: In the present invention, by setting the first sealing mechanism 3, by installing the second motor housing 2 on the first motor housing 1, the second sealing groove 305 on the second motor housing 2 can squeeze the first sealing gasket 302, thereby driving the first sealing gasket 302 to move into the first sealing groove 301, and at the same time driving the first fixing ring 303 to move into the first sealing groove 301. During the movement of the first fixing ring 303, the plurality of first springs 304 are compressed, so that the plurality of first springs 304 generate elastic force, and the plurality of first springs 304 press the first sealing gasket 302 to move into the first sealing groove 301. The fixing ring 303 is squeezed, and the first fixing ring 303 squeezes the first sealing gasket 302, so that the first sealing gasket 302 can fit more closely with the second sealing groove 305, and the first sealing gasket 302 can also be deformed by the squeezing of the first spring 304, so that it can fit more closely with the first sealing groove 301, thereby improving the sealing between the first motor housing 1 and the second motor housing 2, thereby preventing external moisture and dust from entering the interior of the motor, avoiding external moisture and dust from damaging the internal parts of the motor, and extending the service life of the motor.

[0033] A second sealing mechanism 4 is provided in the first motor housing 1. The second sealing mechanism 4 includes a fixed block 407 and a slide 401. One side of the fixed block 407 is connected to one side of the second motor housing 2. The slide 401 is provided on the inner wall of the first motor housing 1. A plurality of second sealing gaskets 402 are slidably connected to the inner wall of the slide 401. One side of the second sealing gasket 402 is connected to a second fixing ring 406. The outer wall of the second fixing ring 406 is slidably connected to the inner wall of the slide 401. A plurality of travel rings are provided on one side of the inner wall of the slide 401. Groove, and the other side of the stroke groove is connected to the inner wall of the first sealing groove 301, and the inner wall of the stroke groove is slidably connected with an extrusion block 405, one side of the extrusion block 405 extends into the first sealing groove 301, the bottom of the extrusion block 405 is connected to one side of the second fixing ring 406, one side of the extrusion block 405 is fitted with one side of the first fixing ring 303, one side of the extrusion block 405 is connected to a fixing plate 403, the top of the fixing plate 403 is connected to a second spring 404, and the other end of the second spring 404 is connected to the inner wall of the first sealing groove 301.

[0034] The specific implementation method is as follows: by setting the second sealing mechanism 4, when the first fixing ring 303 moves in the first sealing groove 301, the first fixing ring 303 will squeeze the multiple squeezing blocks 405 at the same time. Since the squeezing block 405 is provided with an inclined surface on one side, the squeezing block 405 can move toward the center of the circle formed by the multiple second sealing gaskets 402 when squeezed. The movement of the squeezing block 405 drives the fixing plate 403 to move, and drives the second spring 404 to stretch, so that the second spring 404 generates elastic force. At the same time, the squeezing block 405 can drive the second fixing ring 406 to move toward the center of the circle formed by the multiple second sealing gaskets 402. The second fixing ring 406 moves The second sealing gasket 402 is driven by the movement to move toward the center of the circle formed by the multiple second sealing gaskets 402, so that the multiple second sealing gaskets 402 can contact the outer wall of the fixed block 407 at the same time and fit tightly to the outer wall of the fixed block 407, thereby blocking the gap between the fixed block 407 and the first motor housing 1, and further preventing external water vapor and dust from entering the interior of the motor, thereby further improving the sealing of the motor housing. Since the second sealing gaskets 402 in four directions all move toward the center of the circle, during the movement, the sides of adjacent second sealing gaskets 402 will fit together, thereby forming a tight circle.

[0035] Working principle: When in use, the second motor housing 2 is installed on the first motor housing 1, so that the second sealing groove 305 can squeeze the first sealing gasket 302, thereby driving the first sealing gasket 302 and the first fixing ring 303 to move into the first sealing groove 301. During the movement of the first fixing ring 303, the multiple first springs 304 will be compressed, so that the multiple first springs 304 generate elastic force, and can squeeze the first fixing ring 303 and the first sealing gasket 302 through the elastic force, so that the first sealing gasket 302 can fit more closely with the second sealing groove 305, and the first sealing gasket 302 will be deformed due to extrusion, so that it can fit more closely with the first sealing groove 301, thereby improving the sealing between the first motor housing 1 and the second motor housing 2, and preventing external moisture and dust from entering the motor. When the first fixing ring 303 moves in the first sealing groove 301, it can also squeeze the multiple extrusion blocks 405, so that the multiple extrusion blocks 405 can drive the second spring 404 to stretch through the fixing plate 403, and at the same time, the second fixing ring 406 can drive the second sealing gasket 402 to move toward the center of the circle formed by the multiple second sealing gaskets 402, so that the multiple second sealing gaskets 402 can contact the outer wall of the fixing block 407 at the same time and fit tightly to the outer wall of the fixing block 407, thereby blocking the gap between the fixing block 407 and the first motor housing 1, and further preventing external water vapor and dust from entering the interior of the motor. Since the second sealing gaskets 402 in the four directions all move toward the center of the circle, during the movement, the sides of adjacent second sealing gaskets 402 will fit each other, thereby forming a tight circle.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
