Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to a motor housing which is convenient for replacing a stator. Background Art

[0002] The three-phase asynchronous motor is a type of induction motor, which is powered by 380V three-phase AC current. Since the rotor and stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor. The speed of the rotor of the three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor winding generates electromotive force and current due to the relative motion between the rotor winding and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque to achieve energy conversion.

[0003] The three-phase asynchronous motor mainly includes a housing, a stator, a rotor and a drive shaft, among which the housing is used to install the stator, the rotor and the drive shaft, etc. The quality of the housing directly affects the service life of the motor. In order to save installation costs and stably install the stator inside the housing, the stator is generally installed directly inside the housing with an interference fit. This leads to the inconvenience of replacing the stator after the enameled wire on the stator is damaged in the later stage, and the heat dissipation of the housing is generally only carried out through the heat dissipation fins evenly distributed on the outside, and the heat dissipation effect is not good, resulting in the life of the motor being affected.

[0042] In this embodiment, the clean water atomization mechanism 3 includes a water storage tank 31, a water inlet ball valve 32, a connecting pipe 1 33, a water delivery tank 34, an impeller 35, a connecting pipe 2 36 and an atomizing nozzle 37. The water inlet ball valve 32 is fixedly installed in the middle opening of the front end of the water storage tank 31, and the connecting pipe 1 33 is fixedly connected to the lower opening of the right end of the water storage tank 31. The upper end outer periphery of the connecting pipe 1 33 is fixedly connected to the lower end opening of the water delivery tank 34.

The connecting pipe 2 36 is fixedly connected to the upper end opening of the water delivery tank 34, and the upper ends of the connecting pipe 2 36 are connected to the inside of the atomizing nozzle 37.

[0043] In this embodiment, the upper end of the water storage tank 31 is fixedly mounted on the lower end of the motor body 1 by bolts, and the left end of the water delivery tank 34 is fixedly connected to the right end of the protective cover 4.

[0044] In this embodiment, the upper end periphery of the connecting pipe 36 is fixedly connected to the inside of the scraper ring 24, the left end of the atomizing nozzle 37 is fixedly connected to the right end opening of the scraper ring 24, and the inner periphery of the impeller 35 is fixedly connected to the right end periphery of the connecting shaft 28.

[0045] Specifically, the water inlet ball valve 32 is connected to the water pipe, and clean water is added to the interior of the water storage tank 31. Due to the water pressure, the clean water in the water storage tank 31 is sent to the interior of the water delivery tank 34 through the connecting pipe 1 33.

At the same time, the connecting shaft 28 and the fan blades 29 are driven to rotate through the gear 1 25, the gear 2 26 and the gear 3 27 on the right side to blow air into the inner part of the outer shell 11, and a small amount of air is blown to the outside of the outer shell 11. At this time, the connecting shaft 28 drives the impeller 35 to rotate inside the water delivery tank 34, and the clean water inside the water delivery tank 34 is pressurized and sprayed to the outer periphery of the outer shell 11 and the heat dissipation fins 12 through the connecting pipe 2 36 and the atomizing nozzle 37, and then blows air to the outer shell 11. The outer periphery of the outer shell 11 and the heat dissipation fins 12 is used for heat dissipation, and the scraping ring 24 reciprocates on the outer periphery of the outer shell 11 and the heat dissipation fins 12 to scrape off the dust that falls on the upper end of the outer shell 11, thereby preventing the outer periphery of the outer shell 11 and the heat dissipation fins 12 from accumulating dust and causing the heat dissipation effect of the motor to be weakened. The scraping ring 24 reciprocates on the outer periphery of the outer shell 11 and the heat dissipation fins 12 to drive the atomizing nozzle 37 to reciprocate left and right on the outer periphery of the outer shell 11 and the heat dissipation fins 12, and evenly sprinkle clean water on the outer periphery of the outer shell 11 and the heat dissipation fins 12, further improving the outer shell 11 and the heat dissipation fins 1 2 has a heat absorption effect, which improves the heat dissipation effect, and the atomizing nozzle 37 sprays water to the outer periphery of the outer shell 11 and the heat dissipation fins 12 to soften stubborn dust and eliminate static electricity, thereby improving the scraping effect of the scraping ring 24 on stubborn dust, removing dust, and further improving the heat dissipation effect. The fan blades 29 blow air to the inside and outside of the outer shell 11, so that the stator assembly and the rotor assembly inside the outer shell 11 dissipate heat quickly, and at the same time accelerate the evaporation speed of the atomized clean water on the outer periphery of the outer shell 11 and the heat dissipation fins 12, thereby further improving the heat dissipation effect of the outer shell 11 and the heat dissipation fins 12, and extending the service life of the motor.

[0046] In this embodiment, the motor body 1 includes a shell assembly, a limit assembly, a stator assembly and a rotor assembly. The shell assembly includes an outer shell 11, heat dissipation fins 12, a mesh cover 13, an end cover 14, a thermal conductive silicon ring 15 and a limit strip 16. The outer periphery of the outer shell 11 is evenly distributed with heat dissipation fins 12, the left end of the outer shell 11 is fixedly connected to the end cover 14 by bolts, the right end of the outer shell 11 is fixedly installed with the mesh cover 13 by bolts, the interior of the outer shell 11 is fixedly connected with a thermal conductive silicon ring 15, and the interior of the thermal conductive silicon ring 15 is evenly distributed with limit strips 16.

[0047] In this embodiment, the stator assembly includes a stator iron hoop 17, an enameled winding group 18, a limiting opening 19 and a limiting groove 110. The enameled winding group 18 is evenly distributed inside the stator iron hoop 17, the limiting openings 19 are evenly opened at both ends of the stator iron hoop 17, and the limiting grooves 110 are evenly opened on the outer periphery of the stator iron hoop 17. The outer periphery of the stator iron hoop 17 is slidably connected to the inner periphery of the thermal conductive silicon ring 15, and the inner periphery of the limiting groove 110 is slidably connected to the outer periphery of the limiting strip 16.

[0048] In this embodiment, the limiting assembly includes a limiting ring 111, a limiting ring 112 and a limiting hook 113. The side of the limiting ring 111 close to the heat dissipation fins 12 is fixedly installed on the two ends of the outer shell 11 by bolts. The side of the limiting ring 111 close to the heat dissipation fins 12 is fixedly connected to the limiting ring 112. The side of the limiting ring 112 close to the heat dissipation fins 12 is evenly distributed with limiting hooks 113, and the outer periphery of the limiting hooks 113 is snap-fitted into the inside of the limiting opening 19.

[0049] In this embodiment, the rotor assembly includes a rotor iron hoop 114, an enameled winding group 115, a drive shaft 116 and a limit bearing seat 117. The enameled winding group 115 is evenly distributed on the outer periphery of the rotor iron hoop 114, the middle part of the rotor iron hoop 114 is fixedly connected to the drive shaft 116, the right end of the drive shaft 116 is fixedly installed with the limit bearing seat 117, the outer periphery of the rotor iron hoop 114 is rotatably connected to the inner periphery of the stator iron hoop 17, the outer periphery of the left end of the drive shaft 116 is rotatably connected to the middle inner periphery of the end cover 14, and the right end of the limit bearing seat 117 is fixedly installed on the inner right side of the mesh cover 13.

[0050] Specifically, when installing the motor body 1, the stator iron hoop 17 is slid into the interior of the thermally conductive silicon ring 15 through the limiting grooves 110 evenly distributed on the outer circumference and the limiting strips 16 evenly distributed on the inner circumference of the thermally conductive silicon ring 15, and the limiting components on both sides are installed to the two ends of the outer shell 11, so that the limiting hooks 113 are inserted into the interior of the limiting openings 19, and the limiting ring 111 is rotated so that the limiting hooks 113 hook the limiting openings 19, and the threaded openings on the outer circumference of the limiting ring 111 are aligned with the outer edges of the two sides of the outer shell 11. The threaded openings around the stator assembly overlap, and the stator assembly can be limited. After the rotor assembly is installed, the mesh cover 13 and the end cover 14 are installed by bolts to complete the assembly of the motor. By arranging limit components on both sides of the outer shell 11, and evenly distributing limit openings 19 on the outer periphery of both ends of the stator iron hoop 17, and evenly distributing limit grooves 110 on the outer periphery, which cooperate with the limit components and the limit strips 16 evenly distributed on the inner periphery of the thermal conductive silicon ring 15, the stator assembly can be quickly assembled, and it is easy to dismantle in the later stage.

[0051] Working principle: First, when installing the motor body 1, slide the stator iron hoop 17 into the inside of the thermally conductive silicon ring 15 through the limiting grooves 110 evenly distributed on the outer circumference and the limiting strips 16 evenly distributed on the inner circumference of the thermally conductive silicon ring 15, and install the limiting components on both sides to the two ends of the outer shell 11, insert the limiting hook 113 into the inside of the limiting opening 19, and rotate the limiting ring 111 to make the limiting hook 113 hook the limiting opening 19, and make the threaded openings on the outer circumference of the limiting ring 111 coincide with the threaded openings on the outer circumference of the outer shell 11 on both sides, so as to complete the limitation of the stator assembly. After installing the rotor assembly, install the mesh cover 13 and the end cover 14 by bolts to complete the assembly of the motor. By setting the limiting components on both sides of the outer shell 11 and on the two ends of the stator iron hoop 17, The limiting openings 19 are evenly distributed around the periphery, the limiting grooves 110 are evenly distributed on the outer periphery, and the limiting strips 16 evenly distributed on the inner periphery of the limiting assembly and the thermal conductive silicon ring 15 are matched to realize the rapid assembly of the stator assembly, and it is simple to dismantle in the later stage. The water inlet ball valve 32 is connected to the tap water pipe, and clean water is added to the inside of the water storage tank 31. Due to the water pressure, the clean water inside the water storage tank 31 will be sent to the inside of the water delivery tank 34 through the connecting pipe 1 33. During the operation of the motor, the stator assembly and the rotor assembly are quickly transmitted to the outer periphery of the outer shell 11 and the heat dissipation fins 12 through the thermal conductive silicon ring 15, and the gear three 27 on the left side is driven to rotate through the drive shaft 116, and the gear one 25 is driven to rotate through the gear two 26, and then the drive block 23 is driven to rotate in the limiting slide 21 through the bidirectional threaded screw 22. The gear 27 slides back and forth inside, thereby driving the gear 3 27 to slide back and forth on the outer periphery of the outer shell 11 and the heat dissipation fins 12, and the dust that falls on the outer periphery of the outer shell 11 and the heat dissipation fins 12 is scraped off. At the same time, the connecting shaft 28 and the fan blades 29 are driven to rotate through the gear 1 25, the gear 26 and the gear 3 27 on the right side, so as to blow air into the inside of the outer shell 11, and a small amount of wind is blown to the outside of the outer shell 11. At this time, the connecting shaft 28 drives the impeller 35 to rotate inside the water delivery bin 34, and the clean water inside the water delivery bin 34 is pressurized and then sprinkled to the outer periphery of the outer shell 11 and the heat dissipation fins 12 through the connecting pipe 2 36 and the atomizing nozzle 37, so as to dissipate the heat from the outer shell 11 and the heat dissipation fins 12. The outer periphery slides back and forth to scrape off the dust that falls on the upper end of the outer shell 11, thereby preventing the accumulation of dust on the outer periphery of the outer shell 11 and the heat dissipation fins 12, which may weaken the heat dissipation effect of the motor. The scraping ring 24 slides back and forth on the outer periphery of the outer shell 11 and the heat dissipation fins 12, driving the atomizing nozzle 37 to move back and forth left and right on the outer periphery of the outer shell 11 and the heat dissipation fins 12, and evenly spraying clean water on the outer periphery of the outer shell 11 and the heat dissipation fins 12, further improving the heat absorption effect of the outer shell 11 and the heat dissipation fins 12, and improving the heat dissipation effect. The atomizing nozzle 37 sprays water on the outer periphery of the outer shell 11 and the heat dissipation fins 12 to soften stubborn dust and eliminate static electricity, thereby improving the scraping effect of the scraping ring 24 on stubborn dust, removing dust, and further improving the heat dissipation effect.The fan blades 29 blow air inside and outside the outer shell 11, so that the stator assembly and the rotor assembly inside the outer shell 11 dissipate heat quickly, and at the same time accelerate the evaporation speed of the atomized water around the outer shell 11 and the cooling fins 12, further improving the heat dissipation effect of the outer shell 11 and the cooling fins 12, and extending the service life of the motor.
