Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of generators, in particular to a shroud cleaning mechanism of a generator and the generator. BACKGROUND

[0002] A generator is a device for converting mechanical energy into electrical energy. Because the rotor rotates at high speed during the operation of the generator, the generator itself generates a large amount of heat. In order to improve the heat dissipation efficiency, the shroud at the rear end of the generator is designed with heat dissipation holes. However, when the generator is applied to a harvester in agricultural machinery, the working environment of the harvester is harsh, and there are straw debris in the working environment. The straw debris can easily enter the heat dissipation holes, causing the heat dissipation duct of the generator to be blocked, thereby causing poor heat dissipation of the generator, and even causing the generator to burn out. In severe cases, it can also cause a fire.

[0003] In the prior art, a brush structure is provided to clean the heat dissipation holes of the shroud, thereby improving the working life of the generator under such working conditions. However, the brush structure rotates synchronously with the rotor shaft of the generator, and the rotor shaft rotates at a high speed. This can cause the brush to wear out prematurely, thereby shortening the working life of the brush structure. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the present application provides a shroud cleaning mechanism of a generator, which can make the rotational speed of the brush assembly less than the rotational speed of the rotor shaft of the generator, thereby prolonging the working life of the brush assembly.

[0039] The application provides a shroud cleaning mechanism of a generator. The application also provides a generator comprising the shroud cleaning mechanism of the generator.

[0040] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0041] As shown in the drawings, Figure 1 The application provides a shroud cleaning mechanism of a generator. The generator 1 is a device for converting mechanical energy into electrical energy. The heat dissipation air direction of the generator 1 is from the tail end to the fan end. Therefore, the end of the generator 1 is generally provided with a protective cover 2 with air inlet holes. The protective cover 2 is arranged at the end of the generator 1. The housing of the generator comprises a front end cover and a rear end cover. The protective cover 2 is arranged at the end of the rear end cover away from the front end cover. The protective cover 2 is provided with air inlet holes. External air enters the inside of the generator 1 through the air inlet holes to achieve heat dissipation of the generator 1.

[0042] The outer side of the protective cover 2 is provided with a brush assembly 3, i.e. the brush assembly 3 is located on the side of the protective cover 2 away from the generator 1. The brush assembly 3 can clean the air inlet holes on the protective cover 2. Specifically, the brush assembly 3 comprises a brush holder 36 and brush hairs. The brush hairs are arranged on the side of the brush holder 36 facing the protective cover 2. The brush hairs clean the air inlet holes on the protective cover 2. During the cleaning process, the brush assembly 3 can block foreign matters from entering the inside of the generator 1, for example, blocking straw debris when applied to a harvester. In addition, the brush assembly 3 can also prevent foreign matters such as straw debris from being adsorbed and accumulated on the protective cover 2 due to negative pressure. This effectively avoids the problem that the heat dissipation air duct of the generator 1 is easily blocked, leading to poor heat dissipation. When applied to a harvester, this can fundamentally solve the problem of burnout failure of the generator 1 caused by blockage of the heat dissipation air duct in the harvester industry.

[0043] The inner side of the protective cover 2 is provided with a planetary gear assembly, i.e. the planetary gear assembly is arranged between the protective cover 2 and the end of the generator 1. Moreover, the planetary gear assembly is drivingly connected between the rotor shaft 8 of the generator 1 and the brush assembly 3, for example, the input end of the planetary gear assembly is connected with the rotor shaft 8, and the output end is connected with the brush holder 36 of the brush assembly 3, so that the rotor shaft 8 drives the brush assembly 3 to rotate. Due to the speed reduction effect of the planetary gear assembly, the rotating speed of the brush assembly 3 can be lower than that of the rotor shaft 8, thereby prolonging the service life of the brush assembly 3. Moreover, different degrees of speed reduction can be achieved by changing the gear teeth of the planetary gear assembly. No external power input is required. The structure is simple, stable and reliable, which is conducive to improving the service life of the protective cover 2 cleaning mechanism.

[0044] In the scheme, the planetary gear assembly includes a sun gear 6, a planet gear 4, an inner ring gear 7 and a planet carrier 5. The sun gear 6 is fixedly connected with the rotor shaft 8, so that the sun gear 6 rotates synchronously with the rotor shaft 8. The inner ring gear 7 is arranged around the outer periphery of the sun gear 6 and is fixedly connected with the housing or the protective cover 2 of the generator 1, and a gap is reserved between the inner ring gear 7 and the sun gear 6 for installing the planet gear 4. The planet gear 4 is arranged in meshing between the sun gear 6 and the inner ring gear 7. Since the inner ring gear 7 is fixed, the planet gear 4 can rotate along the outer periphery of the sun gear 6 by rotating the sun gear 6. The planet carrier 5 is connected between the planet gear 4 and the brush assembly 3, and the rotating power of the planet gear 4 is transmitted to the brush assembly 3.

[0045] In operation, the rotor shaft 8 of the generator 1 rotates to drive the sun gear 6 to rotate synchronously. Since the inner ring gear 7 is fixed, the planet gear 4 moves in a circular motion around the sun gear 6 to drive the planet carrier 5 to rotate. The planet carrier 5 is connected with the brush assembly 3, thereby driving the brush assembly 3 to rotate to clean the protective cover 2.

[0046] The planet gear 4 is provided in plurality, and all the planet gears 4 are uniformly arranged along the circumferential direction of the sun gear 6. For example, the planet gear 4 is provided in three or five, and preferably in three. In this way, the plurality of planet gears 4 are uniformly arranged on the outer periphery of the sun gear 6, so that the outer periphery of the sun gear 6 is balanced in force, thereby improving the structural stability of the planetary gear assembly.

[0047] In some embodiments, the planet carrier 5 has a first rotating shaft 51 and a second rotating shaft 52, and the first rotating shaft 51 and the second rotating shaft 52 are parallel in axial direction and not in the same straight line. The first rotating shaft 51 is coaxial with the planet gear 4 and is rotationally connected with the planet gear 4, and the second rotating shaft 52 is coaxial with the sun gear 6 and is fixedly connected with the brush assembly 3. In operation, the planet gear 4 drives the first rotating shaft 51 to move in a circular motion around the sun gear 6, and the first rotating shaft 51 and the second rotating shaft 52 rotate synchronously. Since the second rotating shaft 52 is coaxial with the sun gear 6, the rotation of the second rotating shaft 52 is a rotation along the axial direction of the second rotating shaft 52, thereby driving the brush assembly 3 to rotate around the axis of the second rotating shaft 52. In this way, the first rotating shaft 51 and the second rotating shaft 52 are used to achieve the transmission connection between the planet gear 4 and the brush assembly 3, which is beneficial to improve the structural stability and reliability, thereby improving the service life of the planetary gear assembly.

[0048] The second rotating shaft 52 is fixedly connected with the brush assembly 3. For example, the end of the second rotating shaft 52 is provided as a square pin, and the middle of the brush holder 36 is provided with a square hole, and the square pin is inserted into the square hole, so that the brush assembly 3 rotates synchronously with the second rotating shaft 52.

[0049] In specific solutions, the first rotating shaft 51 is arranged through the planetary gear 4, and a first bearing is arranged between the first rotating shaft 51 and the planetary gear 4. The arrangement of the first bearing can improve the stability of relative rotation between the first rotating shaft 51 and the planetary gear 4 and the tightness of structural cooperation, thereby avoiding damage caused by shaking. For example, the planetary gear 4 is provided with a first shaft hole, the first bearing is arranged in the first shaft hole, the outer ring of the first bearing is fixedly connected with the inner wall of the first shaft hole, and the inner ring of the first bearing is fixedly connected with the first rotating shaft 51. Here, the first bearing is a needle bearing.

[0050] The second rotating shaft 52 penetrates the protective cover 2, and a second bearing is arranged between the second rotating shaft 52 and the protective cover 2. The arrangement of the second bearing can improve the stability of relative rotation between the second rotating shaft 52 and the protective cover 2 and the tightness of structural cooperation, thereby avoiding damage caused by shaking. For example, the protective cover 2 is provided with a second shaft hole, the second bearing is arranged in the second shaft hole, the outer ring of the second bearing is fixedly connected with the inner wall of the second shaft hole, and the inner ring of the second bearing is fixedly connected with the second rotating shaft 52.

[0051] In some preferred solutions, a sealing structure is arranged between the second rotating shaft 52 and the protective cover 2. The arrangement of the sealing structure can prevent foreign matters from entering the inside of the generator through the gap between the second rotating shaft 52 and the protective cover 2, thereby avoiding damage to the planetary gear assembly, the stator and the rotor and the like in the inside of the generator. Specifically, the sealing structure can be an O-ring seal or a mechanical seal, or the second bearing can be a sealed bearing to form the above sealing structure.

[0052] A limiting structure is arranged between the first rotating shaft 51 and the planetary gear 4 and / or between the second rotating shaft 52 and the protective cover 2. The above limiting structure is used to limit the axial displacement of the planet carrier 5 along the rotor shaft 8. Thus, the axial limiting of the planet carrier 5 can axially limit the brush assembly 3, thereby enabling the brush assembly 3 to maintain good cleaning effect. Specifically, in the installation, the inner ring of the second bearing can be in interference fit with the second rotating shaft 52, and the outer ring of the second bearing can be in interference fit with the second shaft hole, so as to form the above limiting structure through the second bearing.

[0053] In some embodiments, the radius of the planetary gear assembly is 40%-50% of the radius of the protective cover 2. Here, the radius of the planetary gear assembly is preferably half of the radius of the protective cover 2. Since the planetary gear assembly is located inside the protective cover 2, it will occupy a certain air duct space. Through reasonable design of the size of the planetary gear assembly, the planetary gear assembly can have good speed reduction effect, and the protective cover 2 can have good ventilation effect.

[0054] In some embodiments, as shown in FIG. 6, the brush assembly 3 is arranged on the planet carrier 5, and the planet carrier 5 is arranged on the planet shaft 6. The planet shaft 6 is arranged through the planet carrier 5, and a third bearing is arranged between the planet shaft 6 and the planet carrier 5. The arrangement of the third bearing can improve the stability of relative rotation between the planet shaft 6 and the planet carrier 5 and the tightness of structural cooperation, thereby avoiding damage caused by shaking. For example, the planet carrier 5 is provided with a third shaft hole, the third bearing is arranged in the third shaft hole, the outer ring of the third bearing is fixedly connected with the inner wall of the third shaft hole, and the inner ring of the third bearing is fixedly connected with the planet shaft 6. Figure 2As shown, the brush assembly 3 comprises a brush shaft 31, a rotating rod 32, brush hairs 33 and a gear meshing structure, wherein the brush shaft 31 is coaxially and drivingly connected with the rotor shaft 8 through the planetary gear assembly, so that the rotor shaft 8 can drive the brush shaft 31 to rotate. Specifically, the brush shaft 31 is coaxial and fixedly connected with the second rotating shaft 52 of the planet carrier 5. The rotating rod 32 is axial perpendicular to the brush shaft 31, and is connected with the brush shaft 31, so that the brush shaft 31 can drive the rotating rod 32 to rotate around the axis of the brush shaft 31. Moreover, the rotating rod 32 is rotationally connected with the brush shaft 31, so that the rotating rod 32 can rotate along its own axis relative to the brush shaft 31. Specifically, the brush shaft 31 is provided with a through hole penetrating in the radial direction, and the rotating rod 32 penetrates and is rotationally connected in the through hole. Here, a bearing can be arranged between the through hole and the rotating shaft to improve the rotation stability.

[0055] The brush hairs 33 are arranged on the rotating rod 32, so as to be driven by the rotation of the rotating rod 32 to clean the air inlet on the protective cover. Specifically, the brush hairs 33 can be arranged in a circle along the circumference of the rotating rod 32. Here, the middle part of the rotating rod 32 is rotationally connected with the brush shaft 31, and the two end parts of the rotating rod 32 are provided with brush hairs 33.

[0056] The gear meshing structure is drivingly connected between the protective cover 2 and the rotating rod 32, so as to convert the kinetic energy of the rotating rod 32 rotating along the axis of the brush shaft 31 into the kinetic energy of the rotating rod 32 rotating along its own axis. In this way, when the rotating rod 32 rotates along the axis of the brush shaft 31, the rotating rod 32 can also rotate along its own axis, further improving the cleaning ability of the brush assembly 3.

[0057] In this scheme, as shown, Figure 2 The gear meshing structure comprises a first bevel gear 34 and a second bevel gear 35. The first bevel gear 34 is arranged around the outer periphery of the brush shaft 31 and is fixedly connected with the protective cover. For example, the first bevel gear 34 is provided with a shaft hole, and the brush shaft 31 penetrates along the axis of the first bevel gear 34, so that the brush shaft 31 can rotate in the shaft hole of the first bevel gear 34. The second bevel gear 35 is fixedly connected with the outer periphery of the rotating rod 32, and the second bevel gear 35 is meshed with the first bevel gear 34. In operation, the brush shaft 31 drives the rotating rod 32 to rotate around the axis of the brush shaft 31, and the second bevel gear 35 rotates synchronously with the rotating rod 32, and rolls on the first bevel gear 34, so as to drive the rotating rod 32 to rotate along its own axis, and then drive the brush hairs 33 on the rotating rod 32 to clean the protective cover. In this way, by superimposing the two rotations of the rotating rod 32, the rotating speed of the brush hairs 33 on the rotating rod 32 relative to the protective cover can be reduced, and the service life of the brush assembly 3 can be further increased.

[0058] Two second bevel gears 35 are symmetrically arranged on both sides of the brush shaft 31. In this way, the balance of the gear meshing structure can be improved, and the rotating rod can be prevented from being skewed by force.
