Description

Technical Field

[0001] This utility model relates to the field of electric motor technology, and in particular to a housing for a three-phase asynchronous motor that is easy to install. Background Technology

[0002] Three-phase asynchronous motors mainly consist of a stator and a rotor. The stator is the stationary part, while the rotor is the rotating part. There is a certain air gap between the stator and the rotor. The working principle is based on the interaction between the rotating magnetic field of the stator and the rotor current. Three-phase asynchronous motors are one of the important power devices.

[0003] Three-phase asynchronous motors have a wide range of applications, and the installation methods vary depending on the application. Existing motors are connected by bolt holes in the casing. Horizontal or vertical installation requires additional welding of brackets or installation of shims, which not only increases costs but also affects the motor's heat dissipation and operational stability. It is also not compatible with different installation methods. In addition, traditional motor casings are mostly fastened with bolts, and during maintenance, tools such as wrenches and sockets must be carried to disassemble them one by one. This is especially difficult to do when operating in confined spaces.

[0004] Therefore, in view of the problems of existing three-phase asynchronous motor housings, such as single installation method, cumbersome positioning, complicated maintenance, and lack of angle adjustment, there is a need for a three-phase asynchronous motor housing that is easy to install and solves the above problems. Utility Model Content

[0005] To address the problems of existing three-phase asynchronous motor housings, such as limited installation methods, cumbersome positioning, complex maintenance, and lack of angle adjustment, this application provides a three-phase asynchronous motor housing that is easy to install.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A housing for a three-phase asynchronous motor that is easy to install includes a protective shell. The rear side of the protective shell is connected to a slip ring shell via a fixing assembly. A connecting box is fixedly connected to the bottom outer wall of the slip ring shell. A rotating shaft is provided on the front inner wall of the protective shell. A base is fixedly connected to the bottom side of the protective shell. A terminal box is fixedly connected to the bottom outer wall of the base. A sliding groove is formed on the inner wall of the protective shell and the base. A slider is slidably connected to the outer wall of the sliding groove. The outer wall of the slider is connected to a fixing plate via a rotating assembly. A mounting hole is formed on the outer wall of the end of the fixing plate.

[0008] As a further improvement of this utility model, the fixing component includes a fixing hole opened on the inner wall of the top of the rear side of the protective shell, a slot is opened on the inner wall of the rear side of the protective shell, a locking block is provided on the inner wall of the slot, and the outer wall of the locking block is fixedly connected to the current collector ring shell.

[0009] As a further improvement of this utility model, the rotating assembly includes a connecting shaft one fixedly connected to the outer wall of the slider. A plurality of ratchet teeth are fixedly connected to the outer wall of the connecting shaft one. A limit block one is provided on the outer wall of one of the ratchet teeth, and a limit block two is provided on the outer wall of the other ratchet tooth. A lever is fixedly connected to the outer walls of the limit block one and the limit block two. A connecting shaft two is fixedly connected to the inner wall of the lever. The two sides of the connecting shaft two are rotatably connected to the fixing plate.

[0010] As a further improvement of this utility model, the inner wall of the top of the collector ring shell is threaded with a bolt, and the outer wall of the bottom side of the bolt is threaded with a fixing hole.

[0011] As a further improvement of this utility model, a limiting groove is provided on the outer wall of the left side of the ratchet, and the outer wall of the limiting block is connected to the limiting groove.

[0012] As a further improvement of this utility model, the inner wall of the fixing plate is rotatably connected to the connecting shaft, and the outer wall of the lever is rotatably connected to the fixing plate.

[0013] As a further improvement of this utility model, multiple heat sinks are fixedly connected to the outer wall of the protective shell, and the bottom side of the cable outlet box is connected to the connecting box via wires.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. In this utility model, the shell can be installed horizontally or vertically by means of a sliding groove and an adjustable fixing plate. At the same time, the fixing plate can be prevented from loosening by the rotating component on the inner wall, thereby solving the problems of single installation method and difficult positioning of traditional shells.

[0016] 2. In this utility model, the outer shell can be quickly opened at the slip ring by fixing components. Only one bolt needs to be removed. No special tools are required.

[0030] Example 1:

[0031] like Figures 1-3 As shown, a housing for a three-phase asynchronous motor that is easy to install includes a protective shell 1. The rear side of the protective shell 1 is connected to a slip ring shell 3 via a fixing assembly. A connecting box 4 is fixedly connected to the bottom outer wall of the slip ring shell 3. A rotating shaft 5 is provided on the front inner wall of the protective shell 1. A base 8 is fixedly connected to the bottom side of the protective shell 1. A terminal box 11 is fixedly connected to the bottom outer wall of the base 8. A sliding groove 9 is provided on the inner wall of the protective shell 1 and the base 8. A slider 10 is slidably connected to the outer wall of the sliding groove 9. The outer wall of the slider 10 is connected to a fixing plate 6 via a rotating assembly. A mounting hole 7 is provided on the outer wall of the end of the fixing plate 6.

[0032] Specifically, the protective shell 1, the collector ring shell 3, and the rotating shaft 5 are made of alloy material. The protective shell 1 can adjust the fixing plate 6 in the slide groove 9 of the base 8 according to the required installation environment. The slide groove 9 is 5mm thick, and the base 8 is made of stamped steel plate with a thickness of 12mm. By moving the fixing plate 6, the slider 10 slides in the slide groove 9. After adjusting to the required angle, the fixing plate 6 is adjusted to the installation angle by the rotating component of the fixing plate 6. Then, the M10 threaded bolt is inserted through the mounting hole 7 of the fixing plate 6, and then the M10 threaded bolt is tightened and fixed in the required installation position. When maintenance is required, the collector ring shell 3 can be removed through the fixing component for easy maintenance by workers.

[0033] Example 2:

[0034] As one of the optimized structural designs for Example 1, such as Figure 3 and Figure 5As shown, the fixing assembly includes a fixing hole 19 on the inner wall of the top rear side of the protective shell 1, a slot 21 on the inner wall of the rear side of the protective shell 1, a locking block 22 on the inner wall of the slot 21, the outer wall of the locking block 22 being fixedly connected to the collector ring shell 3, and a bolt 20 being threadedly connected to the inner wall of the top of the collector ring shell 3, the outer wall of the bottom side of the bolt 20 being threadedly connected to the fixing hole 19. During maintenance and disassembly, the bolt 20 is loosened so that it leaves the fixing hole 19, and then the collector ring shell 3 is rotated counterclockwise. The collector ring shell 3 drives the locking block 22 to rotate in the slot 21, and the locking block 22 will disengage from the L-shaped slot 21, after which the collector ring shell 3 can be opened.

[0035] As one of the optimized structural designs for Example 1, such as Figures 2-4 As shown, the rotating assembly includes a connecting shaft 12 fixedly connected to the outer wall of the slider 10. Multiple ratchet teeth 13 are fixedly connected to the outer wall of the connecting shaft 12. One ratchet tooth 13 has a limit block 17 on its outer wall, and another ratchet tooth 13 has a limit block 28 on its outer wall. A lever 15 is fixedly connected to the outer walls of the limit blocks 17 and 28. A connecting shaft 2 16 is fixedly connected to the inner wall of the lever 15. The two sides of the connecting shaft 2 16 are rotatably connected to the fixing plate 6. A limit groove 14 is formed on the left outer wall of the ratchet tooth 13. The limit block 17... The outer wall is connected to the limiting groove 14, the inner wall of the fixing plate 6 is rotatably connected to the connecting shaft 12, and the outer wall of the toggle block 15 is rotatably connected to the fixing plate 6. When the toggle block 15 is moved, it rotates in the fixing plate 6 through the connecting shaft 2 16. Then the toggle block 15 drives the two limiting blocks to leave the ratchet 13 to unlock the fixing plate 6. After the fixing plate 6 is rotated to a suitable angle, the toggle block 15 is moved in the opposite direction. The first limiting block 17 on the toggle block 15 will be locked into the limiting groove 14, and then the second limiting block 18 will be locked into the ratchet 13, thereby preventing the fixing plate 6 from rotating.

[0036] As one of the optimized structural designs for Example 1, such as Figure 2 As shown, multiple heat sinks 2 are fixedly connected to the outer wall of the protective shell 1. The heat sinks 12 are spaced 8-10mm apart and 15mm high, which can quickly dissipate the heat of the motor and reduce the temperature rise by 15-20℃. The bottom side of the outlet box 11 is connected to the connecting box 4 through wires to drive the motor to rotate.

[0037] Working principle: The protective shell 1, the slip ring shell 3, and the rotating shaft 5 are made of alloy material. Heat generated during motor operation is dissipated through multiple heat sinks 2. The rotational speed of the rotating shaft 5 can be controlled via the connecting box 4 and the outlet box 11. A coupling is installed when the rotating shaft 5 is connected to the product being used. The coupling reduces vibration during motor operation, thus preventing movement of the slider 10 within the slide groove 9 due to motor vibration. The protective shell 1 can adjust the fixing plate 6 within the slide groove 9 of the base 8 according to the required installation environment. By moving the fixing plate 6, the slider 10 slides within the slide groove 9. When the slide groove 10 moves, after adjusting to the desired angle, the lever 15 is moved, causing the lever 15 to rotate within the fixing plate 6 via the connecting shaft 16. Subsequently, the lever 15 drives two limiters... After the locking block disengages from the ratchet 13 and unlocks the fixing plate 6, the fixing plate 6 is rotated to a suitable angle and then the lever 15 is pushed in the opposite direction. The first limiting block 17 on the lever 15 will engage with the limiting groove 14, and then the second limiting block 18 will engage with the ratchet 13, thereby preventing the fixing plate 6 from rotating. Then, the M10 threaded bolt is inserted through the mounting hole 7 of the fixing plate 6, and then the M10 threaded bolt is tightened and fixed in the required installation position. When maintenance is required, the bolt 20 is loosened, which will cause the bolt 20 to disengage from the fixing hole 19. Then, the collector ring shell 3 is rotated counterclockwise. The collector ring shell 3 drives the locking block 22 to rotate in the locking groove 21. The locking block 22 will disengage from the L-shaped locking groove 21, and then the collector ring shell 3 can be opened, which will facilitate the worker to carry out maintenance.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
