Description

Technical Field

[0001] The present invention relates to the technical field of gear boxes, and more particularly to an auxiliary reinforcement structure for preventing broken teeth inside gears of a gear box. Background Art

[0002] A gearbox is a mechanical device used to transmit power and change speed. It is mainly composed of gears, shafts, bearings and other components. It is widely used in fields such as wind power generation and industrial machinery. Its core function is to achieve speed increase or speed decrease through gear meshing. The gearboxes in the current prior art are generally installed by combining the upper and lower boxes and then fixing them with bolts. The gear shaft in the gearbox is generally clamped between the contact surfaces of the two box bodies, and power conversion is usually achieved by tooth transmission. However, the existing gearboxes only achieve power transmission in a single direction and cannot adjust the power transmission direction according to demand, which is not convenient when used. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an auxiliary reinforcement anti-tooth breakage structure inside the gearbox gear, aiming to solve the problems raised in the above-mentioned background technology.

[0004] The present invention provides the following technical solution: an auxiliary reinforcement anti-tooth breakage structure inside the gear of a gear box, comprising a gear box body, on which a conversion and conveying assembly is provided; The conversion conveying assembly includes a limit arc cover arranged in the middle of the gear box body, both ends of the limit arc cover are slidably connected to the first extension cover, and one end of each first extension cover is slidably connected to the second extension cover, and a limit block is provided between the two second extension covers, the bottom of the limit block is embedded with a first gear, and the middle of the first gear is provided with a rotating shaft; A second gear is provided on one side of the inner wall of the gear box body, and a third gear is provided on the other side of the inner wall of the gear box body. A linkage gear is provided on the side where the second gear and the third gear are close to each other, and both linkage gears are meshed with the first gear, and the linkage gear on the third gear is rotatably connected to the third gear. The vertical cross-section shape of the limiting arc cover, the first extension cover and the second extension cover is set to be arc-shaped; It can be seen that in the above technical solution, when the third gear rotates, it drives the center block to rotate along the axial direction of the third gear and the linkage gear. When the center block rotates, it drives the limiting column, the first gear and the limiting block to rotate along the axial direction of the second gear, the third gear and the linkage gear, thereby realizing the function of adjusting the position of the first gear, the limiting block and the rotating shaft. The second extension cover is displaced along the guide of the first extension cover, thereby realizing the function of stretching the second extension cover to extend from the first extension cover. At the same time, the second extension cover is slidably connected to the first extension cover, and the first extension cover is slidably connected to the limiting arc cover. Then, when the limiting block is performing position rotation adjustment, the limiting arc cover, the first extension cover and the second extension cover can be continuously sealed, thereby preventing oil leakage inside the gear box. Optionally, in a possible embodiment, a first motor for driving the second gear to rotate is provided on one side of the surface of the gear box body, a second motor for driving the third gear to rotate is provided on the other side of the surface of the gear box body, a center block is provided between the second gear and the linkage gear, a limiting column is provided on the top of the center block, the bottom end of the limiting column extends to the first gear and is rotatably connected to the first gear, the center block is rotatably connected to the linkage gear to which the second gear belongs, the center block and the linkage gear to which the third gear belongs are detachably connected by bolts, and the outer cover of the center block is provided with a guide rail, the guide rail The gears are mounted on the limit blocks by bolts, and guide blocks are provided on both sides of the bottom of the guide rail. The guide blocks are mounted on the bottom of the inner wall of the limit arc cover by bolts, and a limit gear is provided on one side of the two guide blocks, and each of the limit gears is located on one side of the bottom of the third gear and the linkage gear and meshes with the third gear and the linkage gear. The two limit gears are both provided on the limit arc cover and rotatably connected to the limit arc cover. Two conduits are provided at the bottom of the gear box body, and each of the conduits is respectively connected to the corresponding limit gear. A filter element is installed between the two conduits by bolts, and the filter element is connected to the conduit; It can be seen that in the above technical solution, when the limit block is adjusted along the axial rotation of the second gear and the third gear, the guide rail and the guide block rub against each other to guide and limit the limit block during rotation adjustment, thereby ensuring the stability of the limit block during rotation adjustment, and each limit gear is respectively engaged with the second gear and the third gear to rotate the second gear and the third gear to ensure stability, and the linkage gear limits the first gear to ensure the rotation stability of the first gear, thereby preventing the gears from breaking when the gearbox is running, and the limit gear, the conduit and the filter element are connected, which makes it easy for the iron filings generated by gear wear during long-term operation of the gearbox to be deposited in the filter element through the flow of oil, thereby preventing hard particles from embedding into the tooth surface or scratching the tooth surface, preventing pitting, peeling and abnormal wear, and also avoiding tooth breakage.

[0005] Technical effects and advantages of the present invention: 1. The present invention utilizes the meshing design of the second gear, the third gear, and their linked gears with the first gear to achieve flexible switching of power transmission directions through independent drive of dual motors, breaking through the limitations of traditional gearboxes that only transmit in one direction and meeting the power regulation requirements under complex working conditions. 2. The present invention forms a dual limiting mechanism by using a linkage gear and a limiting gear. Multi-point meshing constrains the axial displacement of the gears, reduces load concentration on the tooth surface, and effectively suppresses the risk of tooth breakage. Furthermore, the multi-stage sliding nested structure of the limiting arc cover, the first extension cover, and the second extension cover maintains the integrity of the sealed cavity during gear position adjustment, preventing lubricating oil leakage and ensuring long-term reliable operation of the gearbox. 3. The coordinated structure of the center block, guide rail, and guide block of the present invention provides rigid support for gear rotation and improves transmission stability. The filtration system composed of the filter element and the guide tube can intercept hard particles such as iron filings generated by gear wear in real time, preventing particles from embedding in the tooth surface and causing pitting, peeling, and other failure modes, thereby extending the gear life. To sum up, through the corresponding coordinated use of various structures, the flexible switching of power transmission direction is achieved through the independent drive of dual motors, breaking through the limitation of single-direction transmission of traditional gearboxes and meeting the power adjustment needs under complex working conditions. A dual limiting mechanism is formed by the linkage gear and the limit gear, and the axial displacement of the gear is constrained by multi-point engagement, which reduces the load concentration on the tooth surface and effectively suppresses the risk of tooth breakage. In addition, the multi-stage sliding nested structure of the limit arc cover, the first extension cover and the second extension cover always maintains the integrity of the sealing cavity during the gear position adjustment process, prevents lubricating oil leakage, and ensures the long-term and reliable operation of the gearbox.

DETAILED DESCRIPTION

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] As attached Figure 1-Figure 7 The gearbox gear shown has an auxiliary reinforced anti-tooth breakage structure inside. Through the conversion transmission component set on the gearbox body 1, the power transmission direction can be flexibly switched by independent driving of dual motors, breaking through the limitation of single-direction transmission of traditional gearboxes and meeting the power adjustment requirements under complex working conditions. A double limiting mechanism is formed by the linkage gear 10 and the limit gear 16, and the axial displacement of the gear is constrained by multi-point meshing, which reduces the load concentration on the tooth surface and effectively suppresses the risk of tooth breakage. In addition, the multi-stage sliding nested structure of the limit arc cover 2, the first extension cover 3 and the second extension cover 4 always maintains the integrity of the sealed cavity during the gear position adjustment process, prevents lubricating oil leakage, and ensures long-term and reliable operation of the gearbox. The specific structural arrangement of the component is as follows; The conversion conveying assembly includes a limit arc cover 2 arranged in the middle of the gear box body 1, and both ends of the limit arc cover 2 are slidably connected to the first extension cover 3, and one end of each first extension cover 3 is slidably connected to the second extension cover 4, and a limit block 5 is provided between the two second extension covers 4. The bottom of the limit block 5 is embedded with a first gear 6, and the middle of the first gear 6 is provided with a rotating shaft 7; A second gear 8 is provided on one side of the inner wall of the gear box body 1, and a third gear 9 is provided on the other side of the inner wall of the gear box body 1. A linkage gear 10 is provided on the side where the second gear 8 and the third gear 9 are close to each other. Both linkage gears 10 are engaged with the first gear 6, and the linkage gear 10 on the third gear 9 is rotatably connected to the third gear 9. The vertical cross-section shape of the limit arc cover 2, the first extension cover 3 and the second extension cover 4 are all set to be arc-shaped; A first motor 11 for driving the second gear 8 to rotate is provided on one side of the surface of the gear box body 1, and a second motor 12 for driving the third gear 9 to rotate is provided on the other side of the surface of the gear box body 1. A center block 13 is provided between the second gear 8 and the linkage gear 10. A limiting column 19 is provided on the top of the center block 13. The bottom end of the limiting column 19 extends to the first gear 6 and is rotatably connected to the first gear 6. The center block 13 is rotatably connected to the linkage gear 10 to which the second gear 8 belongs. The center block 13 and the linkage gear 10 to which the third gear 9 belongs are detachably connected by bolts. The outer cover of the center block 13 is provided with a guide rail 14, which is mounted on the limit On the positioning block 5, guide blocks 15 are provided on both sides of the bottom of the guide rail 14. The guide blocks 15 are installed on the bottom of the inner wall of the limiting arc cover 2 by bolts. A limiting gear 16 is provided on one side of the two guide blocks 15, and each limiting gear 16 is located on one side of the bottom of the third gear 9 and the linkage gear 10 and meshes with the third gear 9 and the linkage gear 10. The two limiting gears 16 are both provided on the limiting arc cover 2 and are rotatably connected to the limiting arc cover 2. Two conduits 17 are provided at the bottom of the gear box body 1, and each conduit 17 is respectively connected to the corresponding limiting gear 16. A filter element 18 is installed between the two conduits 17 by bolts, and the filter element 18 is connected to the conduit 17.

[0017] The specific working principle is as follows: When power needs to be output in a single direction: For details, see the attached Figure 2 、 4 As shown in , 5 and 7, the first motor 11 is started to drive the second gear 8 to rotate, and the second gear 8 drives the first gear 6 to engage and rotate through the linkage gear 10. The rotating shaft 7 in the middle of the first gear 6 outputs power, realizing the power conversion from the axial direction of the second gear 8 to the axial direction of the first gear 6, and then realizing the output of power from the axial direction of the second gear 8 to the axial direction of the first gear 6.

[0018] When it is necessary to change the power transmission direction or adjust the output position: Figure 1 and 3 As shown, the second motor 12 is started to drive the third gear 9 to rotate. The third gear 9 drives the center block 13 to rotate along the gear axis through the linkage gear 10. The center block 13 drives the first gear 6 and the limit block 5 to rotate synchronously through the limit column 19, thereby realizing the angle adjustment of the first gear 6 between the second gear 8 and the third gear 9.

[0019] The first motor 11 drives the second gear 8, the linkage gear 10 and the first gear 6 to rotate on the rotating shaft 7 to output power. On this basis, the second motor 12 drives the third gear 9 through the linkage gear 10 to drive the center block 13 to rotate along the gear axis, thereby adjusting the position of the rotating shaft 7, breaking through the limitations of traditional unidirectional transmission, and meeting the power adjustment needs of wind turbine pitch control and industrial machinery in multiple working conditions.

[0020] When the limit block 5 rotates, the second extension cover 4 slides along the first extension cover 3, and the first extension cover 3 slides along the limit arc cover 2. The multi-stage extension cover maintains the continuity of the sealing cavity during dynamic adjustment through the nested cooperation of the arc section to avoid oil leakage.

[0021] Furthermore, the sliding fit between the guide rail 14 and the guide block 15 provides radial limitation for the center block 13, ensuring the accuracy of the gear rotation trajectory; the limit gear 16 is engaged with the second gear 8 and the third gear 9, further restraining the axial movement of the gear and improving the transmission stability. When the gearbox is running, the wear particles carried by the lubricating oil flow into the conduit 17 below the limit gear 16 with the oil, and are intercepted and filtered by the filter element 18 and then circulated back into the box, preventing hard particles from aggravating the wear of the tooth surface.

[0022] Different from the prior art, the present application discloses an auxiliary reinforced anti-tooth breakage structure inside the gearbox gear, which realizes flexible switching of the power transmission direction through independent drive of dual motors, breaking through the limitation of single-direction transmission of traditional gearboxes, and meeting the power adjustment requirements under complex working conditions. A double limiting mechanism is formed by the linkage gear 10 and the limiting gear 16, and the axial displacement of the gear is constrained by multi-point meshing, reducing the load concentration on the tooth surface and effectively suppressing the risk of tooth breakage. In addition, the multi-stage sliding nested structure of the limiting arc cover 2, the first extension cover 3 and the second extension cover 4 always maintains the integrity of the sealing cavity during the gear position adjustment process, prevents lubricating oil leakage, and ensures long-term and reliable operation of the gearbox.

[0023] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
