Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to an asynchronous motor with an end cover structure. Background Technique

[0002] An asynchronous motor is an AC motor. The rotor speed of an asynchronous motor is slightly lower than the speed of the rotating magnetic field, which is why it is called asynchronous. Its structure is relatively simple, reducing the production and maintenance costs; it runs stably and reliably. To facilitate the protection of the asynchronous motor, an asynchronous motor with an end cover structure is required.

[0003] The end cover structure of an asynchronous motor refers to the combination of components that play an important role at both ends of the motor. It is mainly composed of a circular or approximately circular metal end cover body, with a certain thickness and strength, capable of enclosing the stator inner cavity. There is a bearing chamber inside the end cover to accurately install and fix the bearing to support the rotation of the rotor.

[0004] At present, for the end cover structure and asynchronous motors on the market, heat dissipation is carried out on the inside of the device by opening heat dissipation holes or connecting an external electric fan. However, in actual use, the heat dissipation effect of the heat dissipation holes is insufficient, and the external electric fan will increase the use cost and maintenance cost of the device, thus increasing the use cost of the device. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides an asynchronous motor with an end cover structure, aiming to improve the problem that the use cost of the asynchronous motor in the prior art is increased due to the need for external equipment for heat dissipation.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: An asynchronous motor with an end cover structure, an end cover is arranged on the right side of the asynchronous motor, a filter screen is fixedly connected to the right side of the inner wall of the end cover, a conical tooth ring is fixedly connected to the left side of the filter screen, a fixed nest is rotatably connected to the left side of the inner wall of the end cover, a rotating rod is fixedly connected to the left side of the fixed nest, the left side of the rotating rod is fixedly connected to the right output end of the asynchronous motor, a first fan blade is rotatably connected to the periphery of the inner wall of the fixed nest, a fixed block is fixedly connected to the outside of the first fan blade, a conical gear is fixedly connected to the outside of the fixed block, the conical gear is meshed with the conical tooth ring, a second fan blade is fixedly connected to the middle of the right side of the fixed nest, and a positioning mechanism is arranged at the bottom of the asynchronous motor, and the positioning mechanism is used to reduce the noise generated during the operation of the device.

[0007] As a further description of the above technical solution:

[0008] On the front and back sides of the bottom of the inner wall of the asynchronous motor, U-shaped blocks are fixedly connected. On the left and right sides of the inner wall of the U-shaped block, telescopic spring rods are rotatably connected. On the outer side of the telescopic spring rod, an L-shaped plate is rotatably connected. On the inner side of the L-shaped plate, a telescopic sleeve is fixedly connected. The top of the telescopic sleeve is fixedly connected to the asynchronous motor, and the bottom of the L-shaped plate is fixedly connected to a fixing plate.

[0009] As a further description of the above technical solution:

[0010] At the top of the end cover, a hinge is fixedly connected. The end cover is rotatably connected to the asynchronous motor through the hinge.

[0011] As a further description of the above technical solution:

[0012] At the bottom of the end cover, a limiting plate is rotatably connected. At the bottom of the asynchronous motor, a limiting block is fixedly connected. The limiting plate is engaged with the limiting block.

[0013] As a further description of the above technical solution:

[0014] At the top of the asynchronous motor, a controller is fixedly connected. The controller is electrically connected to the asynchronous motor.

[0015] As a further description of the above technical solution:

[0016] On the front and back sides of the outer wall of the asynchronous motor, handles are fixedly connected. On the outer side of the handle, a sheath is fixedly connected.

[0017] As a further description of the above technical solution:

[0018] On the outer periphery of the end cover, positioning blocks are fixedly connected. On the inner side of the positioning block, a positioning hole is provided. On the outer periphery of the outer wall of the asynchronous motor, positioning rods are fixedly connected. The outer side of the positioning rod is fixedly connected to the positioning hole.

[0019] As a further description of the above technical solution:

[0020] At the bottom of the fixing plate, a bottom plate is fixedly connected. On the left and right sides of the outer wall of the bottom plate, mounting holes are provided.

[0021] The utility model has the following beneficial effects:

[0022] 1. In the present utility model, after starting the asynchronous motor, the output end drives the rotating rod, the fixed nest and the first fan blade to rotate. The conical gear on the rotating rod meshes with the conical tooth ring to drive the fan blade to rotate, and the rotation of the fixed nest also drives the second fan blade to rotate. At this time, the air flow is driven into the device for heat dissipation through the filter screen. The uniformly distributed first fan blades improve the air flow velocity and contact area, enhancing the heat dissipation effect. Heat dissipation can be carried out during the operation of the device without additional installation of equipment, thereby reducing the use cost of the device.

[0023] 2. In the present utility model, through the elastic potential energy of the spring telescopic rod, the L-shaped plate can be pushed to move. When the L-shaped plate moves, it will cause the telescopic sleeve to expand and contract, and then drive the fixed plate to move up and down. After the fixed plate device is started, by relying on the reduction of the elastic potential energy of the spring telescopic rod, the collision intensity of mechanical components during the operation of the device is reduced, and the noise generated during the operation of the device is reduced, thereby improving the practicability of the device.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figure 1 、 Figure 3 and Figure 5 As shown in the figure, an embodiment provided by the present invention is an asynchronous motor with an end - cover structure. A end - cover 3 is arranged on the right side of the asynchronous motor 1. A filter screen 11 is fixedly connected to the right side of the inner wall of the end - cover 3. A conical gear ring 10 is fixedly connected to the left side of the filter screen 11. A fixed nest 4 is rotatably connected to the left side of the inner wall of the end - cover 3. A rotating rod 5 is fixedly connected to the left side of the fixed nest 4. The left side of the rotating rod 5 is fixedly connected to the right - side output end of the asynchronous motor 1. First fan blades 6 are rotatably connected to the four - week inner wall of the fixed nest 4. A fixed block 7 is fixedly connected to the outer side of the first fan blade 6. A conical gear 8 is fixedly connected to the outer side of the fixed block 7. The conical gear 8 is meshed with the conical gear ring 10. A second fan blade 9 is fixedly connected to the middle of the right side of the fixed nest 4. A positioning mechanism 2 is arranged at the bottom of the asynchronous motor 1, and the positioning mechanism 2 is used to reduce the noise generated during the operation of the device.

[0033] Specifically, when the asynchronous motor 1 is started, the rotation of its output end can drive the rotation of the rotating rod 5 and the fixed nest 4 thereon. When the fixed nest 4 rotates, it will drive the first fan blades 6 thereon to rotate at the same time, and through the meshing transmission between the conical gear 8 on the rotating rod 5 and the conical gear ring 10, the first fan blades 6 are driven to rotate. At the same time, as the fixed nest 4 rotates, the second fan blade 9 will also be driven to rotate, so as to drive air flow into the device through the filter screen 11 for heat dissipation. At the same time, the uniform distribution of the multiple first fan blades 6 improves the air - flow circulation speed and the contact area with the device, improving the heat - dissipation effect. Among them, the asynchronous motor 1 can use a YSK140 - 35 - 4 - 185 - 2 two - shaft asynchronous AC motor.

[0034] Referring to Figure 4 As shown in the figure, U - shaped blocks 201 are fixedly connected to the front and rear sides of the bottom of the inner wall of the asynchronous motor 1. Spring telescopic rods 202 are rotatably connected to the left and right sides of the inner wall of the U - shaped blocks 201. An L - shaped plate 204 is rotatably connected to the outer side of the spring telescopic rod 202. A telescopic sleeve 203 is fixedly connected to the inner side of the L - shaped plate 204. The top of the telescopic sleeve 203 is fixedly connected to the asynchronous motor 1. A fixing plate 205 is fixedly connected to the bottom of the L - shaped plate 204.

[0035] Specifically, the elastic potential energy of the spring telescopic rod 202 can drive the movement of the L-shaped plate 204. As the L-shaped plate 204 moves, it will drive the telescopic sleeve 203 to expand and contract, and drive the fixed plate 205 thereon to move up and down. When the device is started and fixed through the fixed plate 205, the elastic potential energy of the spring telescopic rod 202 can reduce the collision intensity between mechanical components during the operation of the device, thereby reducing the noise generated during the operation of the device.

[0036] Refer to Figure 2 , Figure 3 and Figure 5 , a hinge 12 is fixedly connected to the top end of the end cover 3, and the end cover 3 is rotatably connected to the asynchronous motor 1 through the hinge 12; a limiting plate 13 is rotatably connected to the bottom of the end cover 3, a limiting block 14 is fixedly connected to the bottom of the asynchronous motor 1, and the limiting plate 13 is engaged with the limiting block 14; a controller 16 is fixedly connected to the top end of the asynchronous motor 1, and the controller 16 is electrically connected to the asynchronous motor 1;

[0037] Specifically, the hinge 12 can facilitate the opening and closing of the end cover 3 for maintaining the interior of the device. By rotating the limiting plate 13 to engage it with the limiting block 14, the accidental opening of the end cover 3 during the operation of the device can be prevented. Through the controller 16, the start and operating power of the asynchronous motor 1 can be controlled, and the controller 16 can use a TC55V motion controller.

[0038] Refer to Figure 1 , Figure 2 and Figure 3 , handles 19 are fixedly connected to the front and rear sides of the outer wall of the asynchronous motor 1, and a sheath 20 is fixedly connected to the outside of the handle 19; positioning blocks 22 are fixedly connected to the four circumferences of the outer wall of the end cover 3, positioning holes 15 are opened inside the positioning blocks 22, positioning rods 21 are fixedly connected to the four circumferences of the outer wall of the asynchronous motor 1, and the outside of the positioning rods 21 is fixedly connected to the positioning holes 15; a bottom plate 17 is fixedly connected to the bottom of the fixed plate 205, and mounting holes 18 are opened on the left and right sides of the outer wall of the bottom plate 17;

[0039] Specifically, through the handle 19 and the sheath 20 thereon, it is convenient to carry and hold the device. By installing it in the positioning hole 15 on the positioning block 22, it is convenient to fix the device. At the same time, the structural strength of the device can be improved by passing the positioning rod 21 through the positioning hole 15. Through the mounting hole 18 at the bottom of the bottom plate 17, it is convenient to disassemble and assemble the device.

[0040] Working principle: Before using the device, first start the asynchronous motor 1. The rotation of its output end can drive the rotating rod 5 and the fixed nest 4 thereon to rotate. When the fixed nest 4 rotates, it will synchronously drive the first fan blade 6 thereon to rotate, and with the meshing transmission between the bevel gear 8 on the rotating rod 5 and the bevel gear ring 10, the first fan blade 6 is driven to rotate. At the same time, as the fixed nest 4 rotates, the second fan blade 9 will also be driven to rotate, so as to drive the airflow into the device through the filter screen 11 for heat dissipation. At the same time, due to the uniform distribution of the multiple first fan blades 6, the flow rate of the airflow and the contact area with the device can be increased, thereby improving the heat dissipation effect;

[0041] Through the elastic potential energy of the spring telescopic rod 202 itself, the L-shaped plate 204 can be driven to move. Along with the movement of the L-shaped plate 204, the telescopic sleeve 203 will be driven to perform a telescopic action, and the fixing plate 205 thereon will be driven to move in the up and down direction. After the device is started and fixed by the fixing plate 205, the elastic potential energy of the spring telescopic rod 202 can be used to reduce the collision intensity between mechanical components during the operation of the device, thereby reducing the noise generated during the operation of the device.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention 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 perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
