Description

Technical Field

[0001] This invention relates to the field of energy-saving motor technology, and in particular to a sealing structure for a four-stage, six-slot motor spindle. Background Technology

[0002] The four-pole, six-slot motor works similarly to a conventional motor, using the magnetic force generated by the stator to attract and drive the rotor to rotate. However, the control method of the four-pole, six-slot motor is more precise than that of a conventional DC motor, employing more advanced electronic control technology. By using advanced motor control algorithms, the motor can achieve higher efficiency and better control performance. Its high power density and high efficiency make the four-pole, six-slot motor widely used in electric motor control, adaptive control, and advanced control fields.

[0003] Currently, most motors are sealed by filling the inside with insulating glue. However, during use, the insulating glue will age due to factors such as the operating environment, temperature, and operating time, resulting in a poorer sealing effect. As a result, external dust and moisture can enter the motor, damaging internal components and affecting the motor's service life.

[0018] Compared with related technologies, the sealing structure of the four-stage six-slot motor spindle provided by the present invention has the following beneficial effects:

[0019] 1. This invention provides a sealing structure for a four-stage, six-slot motor spindle. Through the setting of limiting and locking components, a limiting block is positioned on one side of a limiting sleeve, and a sealing gasket is positioned inside the motor. Then, the operator rotates a connecting rod on one side. The rotation of the connecting rod drives a gear on one side to rotate, which in turn drives a mounting plate on one side to rotate. The rotation of the mounting plate, through the setting of a guide groove, causes a guide rod inside the guide groove to move downwards. When the guide rod moves downwards, it causes the mounting block on one side to move downwards. The downward movement of the mounting block presses down on the lower insertion rod, causing the lower insertion rod to penetrate the shaft sleeve and extend into the inside of the sealing gasket, thereby sealing the sealing gasket and the limiting block. When the mounting plate is fixed and rotates, it will synchronously drive the inner gear two to rotate. The rotation of gear two will drive the rotation of gear three on one side. Since gear three and gear four mesh with each other, when gear three rotates, it will drive gear four on one side to rotate in the opposite direction. When gear three and gear four rotate, they will drive the toothed rail on one side to move upward. When the toothed rail moves upward, it will drive the placement frame to move upward. When the placement frame moves upward, it will drive the top pressing plate to press tightly against the inner wall of the main body, thereby fixing the locking part. The pressing mechanism is installed to cover the outer cavity and press the graphite part axially and radially, ensuring that the graphite part and the bushing fit tightly, and greatly improving the sealing effect of the motor.

[0020] 2. This invention provides a sealing structure for a four-stage six-slot motor spindle. By setting a graphite component on the inner side of the main body, the excellent self-lubricating, heat dissipation, and electrical conductivity of graphite can not only achieve rotary sealing and reduce motor noise and energy consumption, but also dissipate some heat, thereby greatly improving the sealing effect of the motor during use.

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] Please refer to the following: Figures 1-3 The sealing structure of the main shaft of a four-stage six-slot motor includes a main body 1. A fixing platform 4 is provided at the bottom of the main body 1 for fixing the main body 1 and facilitating the overall installation of the motor. A rotor 53 is provided inside the main body 1, and a main shaft 3 is fixedly installed in the middle of the rotor 53. A stator 49 is provided outside the rotor 53. An outer cavity 50 is provided around the main shaft 3 inside the main body 1. A bushing 18 is fixedly installed inside the outer cavity 50 for placing the bushing 18, thus fixing the bushing 18 inside the main body 1. The bushing 18 and the stator 49... A fixed connection is provided. Graphite parts 14 are arranged closely on the outside of the bushing 18. An outer cavity 50 is opened, and the bushing 18 is fixedly installed inside the outer cavity 50 to install the bushing 18 and the graphite parts 14, so that the graphite parts 14 seal the entire motor. After completion, graphite parts 14 are evenly arranged on the outside of the bushing 18 to seal the entire motor. A pressing mechanism is provided at the outer end of the graphite parts 14 to press the graphite parts 14 and improve the sealing effect of the graphite parts 14.

[0035] An end cap 2 is provided on one side of the main body 1 to protect the electronic components inside the main body 1. The end cap 2 is close to one side of the sealing plate 9 to fix the sealing plate 9 and improve the stability of the sealing plate 9. Both the end cap 2 and the main body 1 are provided with sealing grooves 5. A sealing ring 6 is provided inside the sealing groove 5 so that the sealing ring 6 seals between the end cap 2 and the main body 1 and improves the fixing effect of the end cap 2 on the main body 1. Fixing holes 7 are provided on the end cap 2, the sealing ring 6 and the main body 1. Locking bolts 8 are provided inside the fixing holes 7. The end cap 2 is fastened to one side of the main body 1 by the locking bolts 8. After the motor is completely sealed, the end cap 2 is placed on one side of the main body 1 and fixed by the locking bolts 8.

[0036] Please refer to the following: Figures 4-10 The clamping mechanism includes a limiting component and a locking component;

[0037] The limiting component includes a limiting block 21. A limiting sleeve 16 is fitted around the outside of the graphite part 14, tightly pressing against the graphite part 14. After the graphite part 14 is installed, the limiting sleeve 16 is placed on one side of the graphite part 14, squeezing the graphite part 14 to fix it. A pressing mechanism is then set on the outside of the limiting sleeve 16 to secure the graphite part 14 and the inside of the motor. The limiting block 21 is placed on one side of the limiting sleeve 16 to press against it, while simultaneously filling the space between the bushing 18 and the main body 1 to seal and limit the movement of the graphite part 14. Block 21 and limiting sleeve 16 are respectively tightly attached to bushing 18. A sealing gasket 25 is provided at one end of stator 49 and rotor 53. The diameter of sealing gasket 25 is smaller than the diameter of bushing 18, and the outer edge of sealing gasket 25 is tightly attached to the inner wall of bushing 18, thus used for installation and fixation of sealing gasket 25. Sealing effect of sealing gasket 25 is better. Sealing gasket 25 and limiting block 21 are on the same plane, facilitating installation and fixation of sealing gasket 25 and limiting block 21. A placement groove 24 is provided on the limiting block 21, and a sliding groove 32 is provided on one side of the placement groove 24. A slider 33 is fixedly installed on the mounting block 31 at the end opposite to guide rod 30. The slider 33 is slidably disposed inside the sliding groove 32, used for sliding... Block 33 acts as a limiter. When mounting block 31 moves upward, it moves in the slide groove 32 via the slider 33, greatly improving the stability of mounting block 31 and guide rod 30 when moving upward. Limiting holes 19 are provided around the sealing gasket 25, limiting block 21, and bushing 18. Insertion rods 34 are inserted into the limiting holes 19. The diameter of the limiting hole 19 is larger than the diameter of the insertion rod 34. The limiting hole 19 and the insertion rod 34 are compatible. When the insertion rod 34 is inserted into the limiting hole 19, the outer side of the insertion rod 34 fits against the inner wall of the limiting hole 19, thereby improving the stability of limiting block 21 and sealing gasket 25 through the insertion rod 34, and enabling automatic positioning of the limiting block 21. 1. The sealing gasket 25 is fixed. The top of the plug rod 34 is fixedly installed with the mounting block 31. One end of the mounting block 31 is fixedly installed with the guide rod 30. The locking part and the guide rod 30 are connected to each other. Specifically, the limiting part and the locking part are set on one side of the limiting sleeve 16. First, the limiting block 21 is set on one side of the limiting sleeve 16 to squeeze and fix the limiting sleeve 16. After the limiting block 21 is tightly against the limiting sleeve 16, the sealing gasket 25 is set on one side of the stator 49 and the rotor 53 to seal the inside of the motor. Then, the mounting plate 17 is set on one side of the limiting block 21. When placed, the guide rod 30 on the limiting block 21 will be inserted into the inside of the traction groove 35.

[0038] Furthermore, the locking component includes a mounting plate 17, which is located on one side of the limiting block 21 and the limiting sleeve 16. The mounting plate 17 has a traction groove 35, and a guide rod 30 is located inside the traction groove 35. The traction groove 35 is arc-shaped and extends from the outside to the inside. Therefore, when the mounting plate 17 rotates, it drives the guide rod 30 to move up and down following the traction groove 35. The traction groove 35 automatically adjusts the position of the insertion rod 34. The operator rotates the connecting rod 39 located on one side. The rotation of the connecting rod 39 drives the gear 27 on one side to rotate, which in turn drives the mounting plate 17 on one side to rotate. The rotation of the mounting plate 17, through the guide groove, causes the guide rod 30 inside the guide groove to move downwards. When the guide rod 30 moves downward, it will cause the mounting block 31 on one side to move downward. The downward movement of the mounting block 31 will press the lower insertion rod 34 downward, so that the lower insertion rod 34 passes through the bushing 18 and extends into the inside of the sealing gasket 25, thereby fixing the sealing gasket 25 and the limiting block 21. The diameter of the traction groove 35 is larger than the diameter of the guide rod 30. The inner wall of the traction groove 35 fits against the outer side of the guide rod 30 to limit the guide rod 30. At the same time, when the traction groove 35 fits against the guide rod 30, it facilitates the movement of the guide rod 30 and prevents the guide rod 30 from falling off the inside of the traction groove 35. The mounting plate 17 has a toothed groove 23 on the inner side. A gear 26 is provided on the inner side of the toothed groove 23. The gear 26 and the toothed groove 23 mesh with each other. When the mounting plate 17 rotates, it passes through the inner side The tooth groove 23 synchronously drives the second gear 36 to rotate. A connecting column is fixedly installed at one end of the second gear 36, and a third gear 37 is fixedly installed at the other end of the connecting column. A fourth gear 43 is provided on one side of the third gear 37. The third gear 37 and the fourth gear 43 mesh with each other. A limiting plate 44 is movably installed on one side of the third gear 37 and the fourth gear 43. The limiting plate 44 can limit the third gear 37 and the fourth gear 43 and fix the third gear 37 and the fourth gear 43. A placement frame 40 is provided on the outside of the third gear 37 and the fourth gear 43. The toothed rails 42 are fixedly installed on both sides inside the placement frame 40. The two toothed rails 42 mesh with the third gear 37 and the fourth gear 43 respectively. When the third gear 37 and the fourth gear 43 are in opposite directions... When rotated, the placement frame 40 moves up and down synchronously. An extrusion plate 29 is fixedly installed on the top of the placement frame 40. The top of the extrusion plate 29 is arc-shaped and it is tightly attached to the inner wall of the main body 1. The extrusion plate 29 is used to fix the entire extrusion mechanism. A guide block 45 is fixedly installed on one side of the bottom of the placement frame 40. A connecting plate 15 is provided on one side of the placement frame 40. A guide groove 46 is provided on the connecting plate 15. The guide block 45 is slidably disposed inside the guide groove 46. A limit strip is fixedly installed inside the guide groove 46. A placement groove is provided on the guide block 45. The limit strip is slidably disposed inside the placement groove. Therefore, through the limit strip and the placement groove, the guide block 45 can be limited to the inside of the guide groove 46. When the guide block 45 slides inside the guide groove 46...This greatly improves the stability of the guide block 45 during movement. When the guide block 45 moves stably, the placement frame 40 on one side moves up and down synchronously and stably, improving the stability of the extrusion plate 29 when it moves upward. A fixing block 38 is fixedly installed on the connecting plate 15. A connecting rod 39 is rotatably installed on the inner side of the fixing block 38. A gear 27 is fixedly installed at one end of the connecting rod 39. The gear 27 and the tooth groove 23 mesh with each other. The rotation of the gear 27 can drive the mounting plate 17 to rotate. In use, when the mounting plate 17 rotates, it will synchronously drive the inner gear 36 to rotate. The rotation of wheel 36 drives the rotation of gear 37 on one side. Since gear 37 and gear 43 mesh with each other, when gear 37 rotates, it drives gear 43 on one side to rotate in the opposite direction. The rotation of gears 37 and 43 causes the toothed rail 42 on one side to move upwards. The upward movement of the toothed rail 42 causes the placement frame 40 to move upwards. The upward movement of the placement frame 40 causes the top pressing plate 29 to press against the inner wall of the main body 1, thereby fixing the locking component. Furthermore, the pressing action of the pressing plate 29 also fixes the limiting component.

[0039] Furthermore, a sealing plate 9 is provided on one side of the connecting plate 15, and a limiting post 12 is fixedly installed on one side of the sealing plate 9. A second mounting groove 47 is provided on the limiting plate 44, and the limiting post 12 is inserted into the inner side of the second mounting groove 47. The limiting post 12, inserted into the inner side of the second mounting groove 47, can limit the position of the limiting plate 44. After the position of the limiting plate 44 is fixed, the locking component is more securely installed. The limiting post 12, inserted into the inner side of the second mounting groove 47, also provides tension to the sealing plate 9, facilitating its installation and improving its sealing effect. A second limiting post 13 is fixedly installed on one side of the sealing plate 9 on the side with the limiting post 12. A mounting groove 28 is provided at one end of the connecting rod 39, and the limiting post 13 is inserted into the mounting groove 28. The inner side can limit the position of the connecting rod 39. After the position of the connecting rod 39 is fixed, the gear 27 on one side will be fixed simultaneously. After the position of the gear 27 is limited, the mounting plate 17 will be limited simultaneously, so that the locking part is more stable after installation. A card plate 11 is fixedly installed on the outer edge of the sealing plate 9. A card groove 10 is opened on the lower side of one side of the main body 1. The card plate 11 is placed inside the card groove 10. The outer edge of the card plate 11 is close to the inner wall of the card groove 10, so that the card plate 11 provides a good sealing effect on the card groove 10. The card plate 11 is set inside the card groove 10, which facilitates the installation and fixation of the sealing plate 9. A placement cavity is opened in the inner circle of the sealing plate 9. The connecting plate 15 is set inside the placement cavity. Therefore, the sealing plate 9 will also fix the connecting plate 15.

[0040] Please refer to the following: Figure 11A guide plate 51 is fixedly installed on the outer side of the bushing 18. An installation groove 52 is provided on the graphite part 14, which serves to limit the position of the graphite part 14. The graphite part 14 is set inside the outer cavity 50 through the guide plate 51. The graphite parts 14 are evenly arranged on the outer side of the bushing 18, which facilitates the sequential placement of the graphite parts 14. Adjacent graphite parts 14 are tightly attached to each other to avoid gaps between different graphite parts 14, so that the graphite parts 14 have a better sealing effect on the motor. The graphite parts 14 are arranged in an orderly manner for installation and fixation. A limit groove 22 is provided on one side of the limit block 21. One end of the guide plate 51 is inserted into the inner side of the limit groove 22 for installation and fixation of the limit block 21.

[0041] The working principle of the sealing structure for the four-stage six-slot motor spindle provided by this invention is as follows:

[0042] Step 1: When sealing the four-stage six-slot motor, an outer cavity 50 is opened, and then a bushing 18 is fixedly installed inside the outer cavity 50. After completion, graphite parts 14 are evenly arranged on the outside of the bushing 18, and the entire motor is sealed by the graphite parts 14.

[0043] Step 2: After the graphite part 14 is set, a limiting sleeve 16 is set on one side of the graphite part 14. The graphite part 14 is squeezed by the limiting sleeve 16 to fix the graphite part 14. Then, a clamping mechanism is set on the outside of the limiting sleeve 16 to fasten the graphite part 14 and the inside of the motor.

[0044] When using the clamping mechanism, the limiting member and the locking member are set on one side of the limiting sleeve 16. First, the limiting block 21 is set on one side of the limiting sleeve 16 to press and fix the limiting sleeve 16. After the limiting block 21 is pressed against the limiting sleeve 16, the sealing gasket 25 is set on one side of the stator 49 and the rotor 53 to seal the inside of the motor. Then, the mounting plate 17 is set on one side of the limiting block 21. When placed, the guide rod 30 on the limiting block 21 will be inserted into the inside of the traction groove 35.

[0045] After completion, the operator rotates the connecting rod 39 on one side. The rotation of the connecting rod 39 drives the gear 27 on one side to rotate, which in turn drives the mounting plate 17 on one side to rotate. The rotation of the mounting plate 17, through the setting of the guide groove, will drive the guide rod 30 inside the guide groove to move downward. When the guide rod 30 moves downward, it will drive the mounting block 31 on one side to move downward. The downward movement of the mounting block 31 will press the plug rod 34 below downward, so that the plug rod 34 below passes through the bushing 18 and extends into the inside of the sealing gasket 25, thereby fixing the sealing gasket 25 and the limiting block 21.

[0046] When the mounting plate 17 rotates, it will synchronously drive the inner gear 2 36 to rotate. The rotation of gear 2 36 will drive the gear 3 37 on one side to rotate. Since gear 3 37 and gear 43 mesh with each other, when gear 3 37 rotates, it will drive the gear 43 on one side to rotate in the opposite direction. When gear 3 37 and gear 43 rotate, they will drive the toothed rail 42 on one side to move upward. When the toothed rail 42 moves upward, it will drive the placement frame 40 to move upward. When the placement frame 40 moves upward, it will drive the top pressing plate 29 to press against the inner wall of the main body 1, thereby fixing the locking part. And through the pressing of the pressing plate 29, the limiting part is fixed.

[0047] After the locking component is installed, a sealing plate 9 is set on one side of the locking component. The locking component is fixed by the limiting post 12 and the limiting post 13 set on the sealing plate 9, and the sealing plate 9 can also seal the inside of the main body 1.

[0048] After sealing the motor as a whole, the end cover 2 is then placed on one side of the main body 1 and fixed with the locking bolts 8.

[0049] Compared with related technologies, the sealing structure of the four-stage six-slot motor spindle provided by the present invention has the following beneficial effects:

[0050] 1. This invention provides a sealing structure for a four-stage, six-slot motor spindle. Through the setting of limiting and locking components, a limiting block 21 is positioned on one side of a limiting sleeve 16, and a sealing gasket 25 is positioned inside the motor. Then, the operator rotates a connecting rod 39 on one side. The rotation of the connecting rod 39 drives a gear 27 on one side to rotate, which in turn drives a mounting plate 17 on one side to rotate. The rotation of the mounting plate 17, through the setting of the guide groove, causes the guide rod 30 inside the guide groove to move downwards. When the guide rod 30 moves downwards, it causes the mounting block 31 on one side to move downwards. The downward movement of the mounting block 31 presses down on the lower insertion rod 34, causing the lower insertion rod 34 to penetrate the bushing 18 and extend into the inside of the sealing gasket 25, thereby sealing the sealing gasket 25 and the limiting block 21. When the mounting plate 17 is rotated, it will synchronously drive the inner gear 2 36 to rotate. The rotation of gear 2 36 will drive the gear 3 37 on one side to rotate. Since gear 3 37 and gear 43 mesh with each other, when gear 3 37 rotates, it will drive the gear 43 on one side to rotate in the opposite direction. When gear 3 37 and gear 43 rotate, they will drive the gear rail 42 on one side to move upward. When the gear rail 42 moves upward, it will drive the placement frame 40 to move upward. When the placement frame 40 moves upward, it will drive the top pressing plate 29 to press tightly against the inner wall of the main body 1, thereby fixing the locking part. The pressing mechanism is installed to cover the outer cavity 50 and press the graphite part 14 axially and radially to ensure that the graphite part 14 and the bushing 18 fit tightly together, and at the same time greatly improve the sealing effect of the motor.

[0051] 2. The present invention provides a sealing structure for a four-stage six-slot motor spindle. By setting a graphite part 14 on the inner side of the main body 1, the good self-lubricating, heat dissipation and conductivity of graphite can not only achieve rotary sealing, reduce motor noise and energy consumption, but also dissipate some heat, thereby greatly improving the sealing effect of the motor during use.

[0052] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
