Description
Technical Field
[0001] The present invention relates to the technical field of gear boxes, and in particular to a gear box transmission structure and a transmission method thereof. Background Art
[0002] Gearbox is a key component widely used in mechanical transmission systems. Its main function is to transmit power and motion through the meshing of gears. The basic structure of a gearbox includes gears, shafts, bearings, housings, and seals. According to the transmission requirements, the gearbox can be designed as a single-stage or multi-stage transmission. Common types include parallel shaft gearboxes, planetary gearboxes, and worm gearboxes. The design of the gearbox needs to consider factors such as transmission ratio, load capacity, efficiency, and service life, while also meeting the requirements of low noise, low vibration, and high reliability.
[0003] The working principle of the gearbox is based on the meshing transmission of gears. The input shaft drives the driving gear, and then the driven gear transmits the power to the output shaft. The design and manufacturing accuracy of the gear directly affect the transmission efficiency and operation stability. Modern gearboxes usually use high-strength alloy steel as the gear material, and improve its wear resistance and fatigue resistance through heat treatment and surface hardening processes.
[0004] In terms of lubrication, the lubricant demand of the gearbox is crucial. Lubricants can not only reduce the friction and wear of gears and bearings, but also play a role in cooling, rust prevention and cleaning. Generally, gearbox lubricants need to have good viscosity-temperature characteristics, oxidation resistance and anti-wear properties. According to the working conditions and load conditions of the gearbox, choosing the right lubricant type and viscosity grade is the key to ensure its long-term stable operation.
[0005] Gearboxes are prone to vibration and noise under high-speed and heavy-load conditions, affecting running smoothness and service life. Secondly, there are still challenges in the design and management of lubrication systems, and aging and contamination of lubricants may lead to early failure of gears and bearings. In addition, the energy efficiency of existing gearboxes still has room for improvement, especially under partial load conditions, where the transmission efficiency is low. In the future, gearbox technology needs to further optimize design, material selection and lubrication management to improve its performance and reliability. Existing gearboxes are prone to vibration and noise under high-speed and heavy-load conditions, and the design of the lubrication system is insufficient, resulting in increased wear of gears and bearings, affecting transmission efficiency and service life. In addition, the lubrication method of traditional gearboxes is mostly passive lubrication, and the supply of lubricating oil cannot be dynamically adjusted according to actual operating conditions, resulting in unsatisfactory lubrication effect.
[0006] In view of the above situation, in order to overcome the above technical problems, the present invention designs a gear box transmission structure and a transmission method thereof to solve the above technical problems. Summary of the invention
[0007] The technical objective to be achieved by the present invention is to design a gearbox transmission structure and a transmission method thereof, aiming to synchronously lubricate the meshing gears during the rotation of the transmission shaft inside the gearbox. Since the rotation speeds of different gears inside the gearbox are not the same, different rates of lubricating oil are added according to different rotation speeds.
[0008] In order to achieve the above technical objectives, the present invention provides the following technical solutions:
[0009] A gearbox transmission structure specifically includes a housing, a transmission shaft, a transition gear and a rotating gear. The housing adopts an upper and lower split design, and the upper and lower parts are fixedly connected by bolts. This structure is not only convenient for the installation and removal of the gearbox, but also improves the convenience of maintenance. A lubricating oil chamber is provided inside the housing for storing lubricating oil, and the lubricating oil is transported to various transmission components through an oil circuit system to ensure sufficient lubrication of gears and bearings.
[0010] There are two transmission shafts, which are installed on two sides of the housing. One of the transmission shafts is an input shaft for receiving external power; the other transmission shaft is an output shaft for transmitting power to external equipment. The design of the transmission shaft fully considers the load-bearing capacity and rotation stability to meet the transmission requirements under different working conditions. The transition gear is installed on the transmission shaft to transmit power and change the transmission direction. The tooth shape of the transition gear is precisely processed to ensure smooth engagement with the rotating gear and reduce vibration and noise.
[0011] The rotating gear is installed between the two transition gears and meshes with the two transition gears. The rotating gear can be set as a single gear or a gear set, which is selected according to the transmission ratio and load requirements. An internal flow channel is opened inside the toothed disc of the rotating gear for the flow of lubricating oil to ensure that the gear is fully lubricated when running at high speed. In addition, the mounting ring design of the rotating gear further improves the positioning accuracy and operation stability of the gear.
[0012] Through the above structural design, the gearbox transmission structure of the present invention not only realizes efficient power transmission, but also significantly reduces vibration and noise, thereby improving the reliability and service life of the transmission system.
[0013] The transmission shaft is one of the core components of the gearbox transmission structure, and its design directly affects the stability and lubrication effect of the transmission. The transmission shaft includes a shaft body, a balancing chamber, a replenishing pipe, a return spring, a piston, a transition channel and a control assembly. The shaft body, as the main part of the transmission shaft, is made of high-strength alloy steel and has excellent torsional strength and wear resistance. A balancing chamber is provided inside the shaft body to adjust the flow and pressure distribution of the lubricating oil. The inner diameter of the balancing chamber is precisely calculated and is usually set to 1.5-2 times that of the transition channel to ensure that the lubricating oil flows smoothly in the chamber without turbulence.
[0014] The replenishing pipe is arranged outside the balancing chamber, close to the transition channel, and is used to replenish the lubricating oil to the balancing chamber. The design of the replenishing pipe takes into account the flow and pressure requirements of the lubricating oil, ensuring that sufficient lubricating oil can be provided under high load conditions. The return spring is installed inside the balancing chamber and is used to adjust the position of the piston, thereby controlling the flow of the lubricating oil. The elastic force of the return spring is optimized and can be automatically adjusted under different working conditions to ensure the stability of the lubrication system.
[0015] The piston is installed below the return spring and fits tightly with the inner wall of the balance chamber. The up and down movement of the piston is controlled by the elastic force of the return spring and the pressure of the lubricating oil, thereby realizing dynamic adjustment of the lubricating oil. The transition channel is opened below the balance chamber to distribute the lubricating oil to key components such as rotating gears and bearings. The design of the transition channel takes into account the flow path and distribution efficiency of the lubricating oil to ensure that each transmission component is evenly lubricated.
[0016] The control assembly is installed inside the shaft body on both sides of the transition channel to further adjust the flow of lubricating oil. The control assembly includes components such as limit posts, overflow grooves and control discs, which can automatically adjust the flow and direction of lubricating oil according to the pressure changes of lubricating oil. Through the above design, the transmission shaft not only realizes efficient power transmission, but also significantly improves the intelligence level of the lubrication system, ensuring the stable operation of the gearbox under high-speed and heavy-load conditions.
[0017] The replenishing pipe is arranged close to the transition channel, and the inner diameter of the balancing chamber is set to 1.5-2 times of the transition channel. The replenishing pipe is arranged close to the transition channel, which can shorten the flow path of the lubricating oil, reduce the pressure loss of the lubricating oil during the transportation process, and ensure that the lubricating oil can be quickly and efficiently replenished into the balancing chamber, thereby improving the lubrication efficiency. The inner diameter of the balancing chamber is set to 1.5-2 times of the transition channel, which can effectively expand the storage space of the lubricating oil and balance the pressure distribution of the lubricating oil. This design can avoid turbulence or pressure fluctuations of the lubricating oil during the flow process, and ensure that the lubricating oil is smoothly and evenly distributed to each transmission component.
[0018] The shaft body includes a mounting groove and an oil outlet; the mounting groove is provided on the surface of the shaft body, and there are two mounting grooves, and the oil outlet is provided in the middle of the mounting groove, and the oil outlet is arranged in a ring array; the layout of the mounting groove and the oil outlet can effectively improve the uniformity of the distribution of the lubricating oil. The two mounting grooves ensure the stability of the shaft body during installation, and the oil outlet is arranged in a ring array in the middle of the ring groove, which can evenly release the lubricating oil when the shaft body is running, reduce friction and wear, extend the service life of the shaft body, and improve the efficiency and reliability of mechanical operation.
[0019] The shaft body is designed to include not only a mounting groove and an oil outlet, but also further optimize the flow path of the lubricating oil, including a diverter channel, a control chamber, and an initial channel. The diverter channel is located on the inner side of the oil outlet, and is used to guide the lubricating oil from the oil outlet to a more sophisticated distribution network. The control chamber is located at one end of the diverter channel, and serves as the control center for the flow of lubricating oil to ensure the accuracy of oil distribution. The initial channel is opened on the inner side of the control chamber and communicates with the transition channel. This design allows the lubricating oil to smoothly transition from the control chamber to other key parts of the shaft body. This complex flow channel system not only improves the lubrication efficiency, but also effectively reduces the waste of oil, ensures the stability and durability of the shaft body during high-speed operation, but also reduces maintenance costs and failure rates, providing a solid guarantee for the long-term operation of mechanical equipment.
[0020] The control assembly is a key part of the shaft lubrication system. Its structural design is exquisite and its functions are diverse. It mainly includes a limit column, an overflow groove, a control panel, an overflow notch and a support spring. The limit column is installed inside the initial flow channel to limit the flow direction of the lubricating oil, ensure that the lubricating oil can flow along the preset path, and avoid oil overflow or flow to the wrong area. The overflow groove is opened on the surface of the limit column. Its function is to provide an additional flow path when the lubricating oil pressure is too high to prevent the system from being damaged due to excessive pressure. The control panel is installed on the side of the limit column. As a regulating device for the lubricating oil flow, it can dynamically adjust the flow and flow rate of the oil according to actual needs. The overflow notch is opened on the side of the control panel to guide the excess oil to the overflow groove when the lubricating oil flow exceeds the set value, thereby maintaining the stable operation of the system. The support spring is installed on the side of the control panel to provide elastic support for the control panel, so that it can flexibly adjust its position when the lubricating oil pressure changes, while ensuring that the control panel is always in the best working condition. This design not only improves the reliability and accuracy of the lubrication system, but also enhances the adaptability of the shaft under complex working conditions, prolongs the service life of the equipment, while reducing maintenance costs and failure risks.
[0021] The overflow groove and the overflow notch are set in an arc shape, and the overflow groove and the overflow notch are set at intervals. The control disk is set in a truncated cone shape, and the upper surface thereof is set as an arc surface. Setting the overflow groove and the overflow notch in an arc shape and distributing them at intervals can make the lubricating oil more uniform and smooth during the flow process, reduce the resistance and turbulence during the flow of the oil, and thus improve the lubrication efficiency. The control disk is designed to be truncated cone-shaped and the upper surface is an arc surface, which can not only better adapt to the flow characteristics of the lubricating oil, but also flexibly adjust the position when the pressure changes, ensuring the stable control of the lubricating oil flow. This design optimizes the performance of the lubrication system and enhances the stability and reliability of the shaft during high-speed operation.
[0022] The rotating gear is a core component in the mechanical transmission system. Its structural design is reasonable and its functions are clear. It mainly includes a toothed disc, a transmission tooth and a mounting ring. As the main part of the rotating gear, the toothed disc carries the main transmission function, and its strength and precision directly affect the performance of the entire transmission system. The transmission teeth are evenly installed on the sides of the toothed disc, and transmit power by meshing with adjacent gears to ensure the smoothness and efficiency of power transmission. There are two mounting rings, which are respectively installed on the upper and lower surfaces of the toothed disc to fix the position of the rotating gear to ensure that it remains stable during operation and avoid vibration or offset affecting the transmission efficiency. This design not only improves the carrying capacity and durability of the rotating gear, but also simplifies the installation and maintenance process, making the transmission system more reliable in high-speed operation. At the same time, the double-sided setting of the mounting ring further enhances the overall stability of the gear, reduces wear and failure caused by uneven force, extends the service life of the equipment, and provides a strong guarantee for the efficient operation of the mechanical transmission system.
[0023] The internal design of the toothed disc is exquisite, and an internal flow channel is provided. This design not only optimizes the structure of the gear, but also improves its functionality. One end of the internal flow channel is provided on the side of the toothed disc and is located between the transmission teeth. This layout allows the lubricating oil to be evenly distributed to the meshing part of the transmission teeth through the flow channel, effectively reducing the friction and wear of the gears when running at high speeds, thereby extending the service life of the gears and improving the transmission efficiency. In addition, a transition ring groove is provided inside the mounting ring. This design further optimizes the flow path of the lubricating oil, allowing the lubricating oil to smoothly transition from the internal flow channel of the toothed disc to the mounting ring, and evenly distributed to other key parts of the gear through the transition ring groove. This combination of flow channel and ring groove design not only enhances the lubrication effect, but also ensures the stable operation of the gear under complex working conditions, reducing the risk of failure caused by insufficient lubrication. The overall design takes into account functionality, reliability and durability, and provides strong support for the efficient operation of the mechanical transmission system.
[0024] A gearbox transmission method, the steps of the method are as follows:
[0025] Step 1: When installing the gearbox, first ensure that the base platform is flat and stable to avoid vibration during operation. Place the gearbox in the predetermined position, use a level to adjust the level, ensure the centering accuracy of the input and output shafts, tighten the anchor bolts, and check whether the coupling or pulley is installed correctly. During the installation process, pay attention to protecting the internal parts of the gearbox to prevent dust or foreign matter from entering;
[0026] Step 2: Before debugging, check whether the gearbox rotates flexibly and without any jamming. After starting the equipment, run it at no load first, observe the vibration, noise and temperature rise of the gearbox, gradually increase the load, check whether the transmission is stable, and record the operating parameters. If any problems are found during the debugging process, stop the machine and make adjustments in time;
[0027] Step 3: Before formal operation, ensure that all fasteners are not loose. After starting the equipment, monitor the operating status of the gearbox, including parameters such as vibration, noise, temperature and oil pressure. Regular inspections are required during the initial operation to ensure that there is no abnormal wear or overheating. Avoid overloading or frequent starting and stopping during operation to extend the service life of the gearbox.
[0028] Step 4: During the rotation of the transmission shaft, the lubricating oil in the transition channel enters the control cavity through the initial flow channel under the action of centrifugal force, enters the rotating gear through the branch flow channel and the oil outlet, and is transported to between the transmission teeth through the internal flow channel, thereby lubricating the meshing movement of the transition gear and the rotating gear;
[0029] Step 5: If abnormal noise, vibration or excessive temperature rise is found during operation, the machine must be stopped and checked immediately. Common faults include gear wear, bearing damage or poor lubrication. Analyze the cause according to the fault phenomenon, replace damaged parts or adjust the installation accuracy. After the processing is completed, re-debug and test run to ensure that the problem is completely solved.
[0030] The beneficial effects of the present invention are as follows:
[0031] 1. The present invention provides internal flow channels, transition ring grooves, overflow grooves and overflow gaps, so that the lubricating oil can be evenly distributed to key parts such as the shaft body and rotating gears, effectively reducing friction and wear and extending the service life of the equipment. The design of the control components (such as the limit column, control disk and support spring) can dynamically adjust the flow and pressure of the lubricating oil to ensure that the system remains stable during high-speed operation and avoid failures caused by pressure fluctuations or insufficient lubrication.
[0032] 2. The design of the mounting groove, mounting ring and other structures in the present invention not only simplifies the installation process, but also enhances the overall stability of the shaft and gear, and reduces wear and failure caused by vibration or uneven force. The optimized design of the lubrication system reduces the waste of lubricating oil and reduces the failure rate of the equipment, thereby reducing the maintenance frequency and maintenance cost. The design of the arc-shaped overflow groove and overflow notch, the truncated cone-shaped control panel and other designs enable the system to better adapt to complex working conditions such as high speed and high pressure, and improve the adaptability and reliability of the equipment.

DETAILED DESCRIPTION
[0045] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0046] like Figure 1-9As shown, a gearbox transmission structure specifically includes a housing 1, a transmission shaft 2, a transition gear 3 and a rotating gear 4. The housing 1 adopts an upper and lower split design, and the upper and lower parts are fixedly connected by bolts. This structure is not only convenient for the installation and disassembly of the gearbox, but also improves the convenience of maintenance. A lubricating oil chamber is provided inside the housing 1 for storing lubricating oil, and the lubricating oil is transported to each transmission component through the oil circuit system to ensure sufficient lubrication of the gears and bearings.
[0047] There are two transmission shafts 2, which are respectively installed on two sides of the housing 1. One of the transmission shafts 2 is an input shaft for receiving external power; the other transmission shaft 2 is an output shaft for transmitting power to an external device. The design of the transmission shaft 2 fully considers the load-bearing capacity and rotational stability to meet the transmission requirements under different working conditions. The transition gear 3 is installed on the transmission shaft 2 to transmit power and change the transmission direction. The tooth shape of the transition gear 3 is precisely processed to ensure smooth engagement with the rotating gear 4 and reduce vibration and noise.
[0048] The rotating gear 4 is installed between the two transition gears 3 and meshes with the two transition gears 3. The rotating gear 4 can be set as a single gear or a gear set, which is selected according to the transmission ratio and load requirements. An internal flow channel 411 is opened inside the toothed disc 41 of the rotating gear 4 for the flow of lubricating oil to ensure that the gear is fully lubricated when running at high speed. In addition, the mounting ring 43 design of the rotating gear 4 further improves the positioning accuracy and operation stability of the gear.
[0049] Through the above structural design, the gearbox transmission structure of the present invention not only realizes efficient power transmission, but also significantly reduces vibration and noise, thereby improving the reliability and service life of the transmission system.
[0050] like Figure 4 As shown, the transmission shaft 2 is one of the core components of the gearbox transmission structure, and its design directly affects the stability and lubrication effect of the transmission. The transmission shaft 2 includes a shaft body 21, a balancing chamber 22, a replenishing pipe 23, a reset spring 24, a piston 25, a transition channel 26 and a control assembly 27. The shaft body 21, as the main part of the transmission shaft 2, is made of high-strength alloy steel and has excellent torsional strength and wear resistance. A balancing chamber 22 is provided inside the shaft body 21 to adjust the flow and pressure distribution of the lubricating oil. The inner diameter of the balancing chamber 22 is precisely calculated and is usually set to 1.5-2 times that of the transition channel 26 to ensure that the flow of the lubricating oil in the chamber is smooth and turbulent.
[0051] The replenishing pipe 23 is arranged outside the balancing chamber 22, close to the transition channel 26, and is used to replenish the lubricating oil to the balancing chamber 22. The design of the replenishing pipe 23 takes into account the flow rate and pressure requirements of the lubricating oil, ensuring that sufficient lubricating oil can still be provided under high load conditions. The return spring 24 is installed inside the balancing chamber 22, and is used to adjust the position of the piston 25, thereby controlling the flow rate of the lubricating oil. The elastic force of the return spring 24 is optimized and can be automatically adjusted under different working conditions to ensure the stability of the lubrication system.
[0052] The piston 25 is installed below the return spring 24 and fits tightly with the inner wall of the balance chamber 22. The up and down movement of the piston 25 is controlled by the elastic force of the return spring 24 and the pressure of the lubricating oil, thereby realizing dynamic adjustment of the lubricating oil. The transition channel 26 is opened below the balance chamber 22 to distribute the lubricating oil to key components such as the rotating gear 4 and the bearing. The design of the transition channel 26 takes into account the flow path and distribution efficiency of the lubricating oil to ensure that each transmission component is evenly lubricated.
[0053] The control assembly 27 is installed inside the shaft body 21 on both sides of the transition channel 26 to further adjust the flow of the lubricating oil. The control assembly 27 includes components such as a limit column 271, an overflow groove 272 and a control disk 273, which can automatically adjust the flow and direction of the lubricating oil according to the pressure change of the lubricating oil. Through the above design, the transmission shaft 2 not only realizes efficient power transmission, but also significantly improves the intelligence level of the lubrication system, ensuring the stable operation of the gearbox under high-speed and heavy-load conditions.
[0054] The replenishing pipe 23 is arranged close to the transition channel 26, and the inner diameter of the balancing chamber 22 is set to 1.5-2 times of the transition channel 26. The replenishing pipe 23 is arranged close to the transition channel 26, which can shorten the flow path of the lubricating oil, reduce the pressure loss of the lubricating oil during the transportation process, and ensure that the lubricating oil can be quickly and efficiently replenished into the balancing chamber 22, thereby improving the lubrication efficiency. The inner diameter of the balancing chamber 22 is set to 1.5-2 times of the transition channel 26, which can effectively expand the storage space of the lubricating oil and balance the pressure distribution of the lubricating oil. This design can avoid turbulence or pressure fluctuations in the flow of the lubricating oil, and ensure that the lubricating oil is smoothly and evenly distributed to each transmission component.
[0055] like Figure 6As shown, the shaft body 21 includes a mounting groove 211 and an oil outlet 212; the mounting groove 211 is opened on the surface of the shaft body 21, and there are two mounting grooves 211. The oil outlet 212 is opened in the middle of the mounting groove 211, and the oil outlet 212 is arranged in a ring array; the layout of the mounting groove 211 and the oil outlet 212 can effectively improve the uniformity of the distribution of the lubricating oil. The two mounting grooves 211 ensure the stability of the shaft body 21 during installation, and the oil outlet 212 is arranged in a ring array in the middle of the ring groove, which can evenly release the lubricating oil when the shaft body 21 is running, reduce friction and wear, extend the service life of the shaft body 21, and improve the efficiency and reliability of mechanical operation.
[0056] The shaft body 21 is designed to include not only a mounting groove 211 and an oil outlet 212, but also further optimize the flow path of the lubricating oil, including a diverter channel 213, a control chamber 214, and an initial channel 215. The diverter channel 213 is located on the inner side of the oil outlet 212, and is used to guide the lubricating oil from the oil outlet 212 to a more sophisticated distribution network. The control chamber 214 is located at one end of the diverter channel 213, and serves as the control center for the flow of the lubricating oil to ensure the accuracy of the oil distribution. The initial channel 215 is opened on the inner side of the control chamber 214 and communicates with the transition channel 26. This design enables the lubricating oil to smoothly transition from the control chamber 214 to other key parts of the shaft body 21. This complex channel system not only improves the lubrication efficiency, but also effectively reduces the waste of oil, ensures the stability and durability of the shaft body 21 during high-speed operation, and also reduces the maintenance cost and failure rate, providing a solid guarantee for the long-term operation of mechanical equipment.
[0057] like Figure 7As shown, the control assembly 27 is a key part of the lubrication system of the shaft body 21. Its structural design is exquisite and its functions are diverse. It mainly includes a limit column 271, an overflow groove 272, a control disc 273, an overflow notch 274 and a support spring 275. The limit column 271 is installed inside the initial flow channel 215 to limit the flow direction of the lubricating oil, ensure that the lubricating oil can flow along the preset path, and avoid oil overflow or flow to the wrong area. The overflow groove 272 is opened on the surface of the limit column 271. Its function is to provide an additional flow path when the lubricating oil pressure is too high to prevent the system from being damaged due to excessive pressure. The control disc 273 is installed on the side of the limit column 271 as a regulating device for the lubricating oil flow, which can dynamically adjust the flow and flow rate of the oil according to actual needs. The overflow notch 274 is opened on the side of the control disc 273 to guide the excess oil to the overflow groove 272 when the lubricating oil flow exceeds the set value, thereby maintaining the stable operation of the system. The support spring 275 is installed on the side of the control disk 273 to provide elastic support for the control disk 273, so that it can flexibly adjust its position when the lubricating oil pressure changes, while ensuring that the control disk 273 is always in the best working state. This design not only improves the reliability and accuracy of the lubrication system, but also enhances the adaptability of the shaft body 21 under complex working conditions, prolongs the service life of the equipment, and reduces maintenance costs and failure risks.
[0058] The overflow groove 272 and the overflow notch 274 are set to be circular arc-shaped, and the overflow groove 272 and the overflow notch 274 are set at intervals. The control disk 273 is set to be truncated cone-shaped, and the upper surface thereof is set to be an arc surface. The overflow groove 272 and the overflow notch 274 are set to be circular arc-shaped and spaced apart, so that the lubricating oil can flow more evenly and smoothly during the process, reduce the resistance and turbulence during the flow of the oil, and thus improve the lubrication efficiency. The control disk 273 is designed to be truncated cone-shaped and the upper surface is an arc surface, which can not only better adapt to the flow characteristics of the lubricating oil, but also flexibly adjust the position when the pressure changes, to ensure the stable control of the flow of the lubricating oil. This design optimizes the performance of the lubrication system and enhances the stability and reliability of the shaft body 21 during high-speed operation.
[0059] like Figure 8As shown, the rotating gear 4 is the core component of the mechanical transmission system, and its structural design is reasonable and its functions are clear. It mainly includes a toothed disc 41, a transmission tooth 42 and a mounting ring 43. As the main part of the rotating gear 4, the toothed disc 41 carries the main transmission function, and its strength and precision directly affect the performance of the entire transmission system. The transmission tooth 42 is evenly installed on the side of the toothed disc 41, and transmits power by meshing with adjacent gears to ensure the stability and efficiency of power transmission. There are two mounting rings 43, which are respectively installed on the upper and lower surfaces of the toothed disc 41 to fix the position of the rotating gear 4, ensure that it remains stable during operation, and avoid vibration or offset affecting the transmission efficiency. This design not only improves the carrying capacity and durability of the rotating gear 4, but also simplifies the installation and maintenance process, making the transmission system more reliable in high-speed operation. At the same time, the double-sided setting of the mounting ring 43 further enhances the overall stability of the gear, reduces wear and failure caused by uneven force, prolongs the service life of the equipment, and provides a strong guarantee for the efficient operation of the mechanical transmission system.
[0060] like Fig. 9 As shown, the internal design of the toothed disc 41 is exquisite, and an internal flow channel 411 is provided. This design not only optimizes the structure of the gear, but also improves its functionality. One end of the internal flow channel 411 is provided on the side of the toothed disc 41 and is located between the transmission teeth 42. Such a layout enables the lubricating oil to be evenly distributed to the meshing part of the transmission teeth 42 through the flow channel, effectively reducing the friction and wear of the gears when running at high speed, thereby extending the service life of the gears and improving the transmission efficiency. In addition, a transition ring groove 431 is provided inside the mounting ring 43. This design further optimizes the flow path of the lubricating oil, so that the lubricating oil can smoothly transition from the internal flow channel 411 of the toothed disc 41 to the mounting ring 43, and is evenly distributed to other key parts of the gear through the transition ring groove 431. This combination of flow channel and ring groove design not only enhances the lubrication effect, but also ensures the stable operation of the gear under complex working conditions, and reduces the risk of failure caused by insufficient lubrication. The overall design takes into account functionality, reliability and durability, and provides strong support for the efficient operation of the mechanical transmission system.
[0061] A gearbox transmission method, the steps of the method are as follows:
[0062] Step 1: When installing the gearbox, first ensure that the base platform is flat and stable to avoid vibration during operation. Place the gearbox in the predetermined position, use a level to adjust the level, ensure the centering accuracy of the input and output shafts, tighten the anchor bolts, and check whether the coupling or pulley is installed correctly. During the installation process, pay attention to protecting the internal parts of the gearbox to prevent dust or foreign matter from entering;
[0063] Step 2: Before debugging, check whether the gearbox rotates flexibly and without any jamming. After starting the equipment, run it at no load first, observe the vibration, noise and temperature rise of the gearbox, gradually increase the load, check whether the transmission is stable, and record the operating parameters. If any problems are found during the debugging process, stop the machine and make adjustments in time;
[0064] Step 3: Before formal operation, ensure that all fasteners are not loose. After starting the equipment, monitor the operating status of the gearbox, including parameters such as vibration, noise, temperature and oil pressure. Regular inspections are required during the initial operation to ensure that there is no abnormal wear or overheating. Avoid overloading or frequent starting and stopping during operation to extend the service life of the gearbox.
[0065] Step 4: During the rotation of the transmission shaft 2, the lubricating oil in the transition channel 26 enters the control chamber 214 through the initial flow channel 215 under the action of centrifugal force, and enters the rotating gear 4 through the branch flow channel 213 and the oil outlet 212, and is transported to between the transmission teeth 42 through the internal flow channel 411, thereby lubricating the meshing movement of the transition gear 3 and the rotating gear 4;
[0066] Step 5: If abnormal noise, vibration or excessive temperature rise is found during operation, the machine must be stopped and checked immediately. Common faults include gear wear, bearing damage or poor lubrication. Analyze the cause according to the fault phenomenon, replace damaged parts or adjust the installation accuracy. After the processing is completed, re-debug and test run to ensure that the problem is completely solved.
[0067] The structure of the housing 1 of the present invention: the housing 1 is set as an upper and lower split structure, and the middle is fixedly connected by bolts. This design facilitates the installation, disassembly and maintenance of the gearbox. There are two transmission shafts 2, which are respectively installed on the two sides of the housing 1. One of the transmission shafts 2 is an input shaft for receiving external power; the other transmission shaft 2 is an output shaft for transmitting power to an external device. The transmission shaft 2 includes a shaft body 21, a balancing chamber 22, a replenishing pipe 23, a return spring 24, a piston 25, a transition channel 26 and a control component 27. The shaft body 21: as the main part of the transmission shaft 2, a balancing chamber 22 is opened inside the shaft body 21 for adjusting the flow of lubricating oil. The balancing chamber 22: its inner diameter value is 1.5-2 times that of the transition channel 26, ensuring that the lubricating oil flows smoothly in the chamber. The replenishing pipe 23: arranged on the outside of the balancing chamber 22, close to the transition channel 26, for replenishing lubricating oil. The return spring 24 and the piston 25: installed inside the balancing chamber 22, for adjusting the flow and pressure of the lubricating oil. Transition channel 26: opened below the balance chamber 22, connected to the control assembly 27, used for distributing lubricating oil. Control assembly 27: includes a limit column 271, an overflow groove 272, a control plate 273, an overflow notch 274 and a support spring 275, used for dynamically controlling the flow of lubricating oil.
[0068] The gear structure of the present invention: the transition gear 3 is installed on the transmission shaft 2, and the rotating gear 4 is installed between the two transition gears 3 and meshes with the transition gear 3. The rotating gear 4 includes a toothed disc 41, a transmission tooth 42 and a mounting ring 43. The toothed disc 41: as the main body of the rotating gear 4, an internal flow channel 411 is provided inside for the flow of lubricating oil. The transmission tooth 42: is installed on the side of the toothed disc 41 for transmitting power. The mounting ring 43: is arranged on the upper and lower surfaces of the toothed disc 41, and a transition ring groove 431 is provided inside for the distribution of lubricating oil.
[0069] Lubrication system of the present invention: The shaft body 21 also includes a diverter channel 213, a control chamber 214 and an initial channel 215. The diverter channel 213 is provided on the inner side of the oil outlet 212, the control chamber 214 is provided at one end of the diverter channel 213, and the initial channel 215 is communicated with the control chamber 214. The lubricating oil enters the control chamber 214 through the diverter channel 213, and is then distributed to each transmission component through the initial channel 215 and the transition channel 26. The control assembly 27 dynamically adjusts the flow and pressure of the lubricating oil through the cooperation of the limit column 271, the overflow groove 272 and the control disk 273 to ensure sufficient lubrication of the gears and bearings.
[0070] The dynamic lubrication control of the present invention: the overflow groove 272 and the overflow notch 274 in the control assembly 27 are set in an arc shape, and are spaced apart on the limit column 271 and the control disk 273. The control disk 273 is set in a truncated cone shape, and its upper surface is an arc surface, which can automatically adjust its position when the lubricating oil pressure changes, thereby adjusting the flow of the lubricating oil. The support spring 275 is used to maintain the initial position of the control disk 273 to ensure the stability of the lubrication system.
[0071] The gearbox transmission structure of the present invention has a high demand for lubricating oil. The lubricating oil needs to have good viscosity-temperature characteristics, oxidation resistance and anti-wear properties to ensure the lubrication effect under high load and high speed conditions. The viscosity grade of the lubricating oil should be selected according to the operating temperature and load conditions of the gearbox. In addition, the lubricating oil needs to be replaced regularly and kept clean to prevent impurities from entering the lubrication system.
[0072] During operation of the present invention, the rotating shaft rotates driven by the motor or other input device, so that the rotating gear 4 installed on the transmission shaft 2 drives the transition gear 3 to rotate, and the rotating gear 4 meshing with the other side of the transition gear 3 also rotates accordingly, and drives the installed transmission shaft 2 to rotate at a variable speed;
[0073] The staff can add lubricating oil into the transmission shaft 2 through the replenishing pipe 23. A one-way valve is arranged inside the replenishing pipe 23, so that the lubricating oil can only enter the transmission shaft 2 from the outside. The lubricating oil enters the balance chamber 22, and the return spring 24 drives the piston 25 to squeeze the hydraulic oil, so that it flows into the transition channel 26, so that the transition channel 26 is filled with hydraulic oil.
[0074] When the transmission shaft 2 rotates, the control assembly 27 overcomes the elastic force of the support spring 275 and slides outward under the drive of the centrifugal force, so that the lubricating oil can pass through the initial flow channel 215, and enter the control chamber 214 through the overflow groove 272 and the overflow notch 274 in sequence, and enter the installation groove 211 after being collected from the branch flow channel 213. When the installation groove 211 is full of lubricating oil, the pressure will cause the lubricating oil to pass through the internal flow channel 411 and overflow between the transmission teeth 42, thereby achieving the lubrication effect between the rotating gear 4 and the transition gear 3;
[0075] Furthermore, since the displacement distance of the control assembly 27 depends on the centrifugal forces of different magnitudes brought about by the rotation speed of the transmission shaft 2, the present invention can adjust the filling rate of the lubricating oil according to the rotation speed.
