Description

Technical Field

[0001] The invention relates to the technical field of three-ring reducers, in particular to a three-ring reducer for high-temperature resistant self-lubricating roller rolling. Background Art

[0002] The three-ring reducer is composed of three identical internal gear ring plates driving an external gear output, so it is called a three-ring reducer. It is a parallel shaft-dynamic shaft gear transmission reducer. The gear meshing motion belongs to the dynamic shaft gear train. It has the characteristics of a small tooth difference planetary transmission. The output and input shafts are arranged in parallel, and it has the characteristics of a parallel shaft cylindrical gear reducer. It has the advantages of strong load and overload capacity, large transmission ratio, dense classification, high efficiency, compact structure, small size, light weight, convenient assembly and maintenance, and wide applicability.

[0003] For example, the "self-lubricating cycloidal pinwheel reducer" with publication number CN219432407U, the self-lubricating cycloidal pinwheel reducer includes a reducer body, an oil storage box is fixedly connected to the upper end of the reducer body, an oil storage chamber is opened inside the oil storage box, an oil inlet pipe is fixedly connected to the inside of the oil storage chamber, one end of the oil inlet pipe passes through the interior of the reducer body, an adjusting block is rotatably connected to the inside of the oil inlet pipe, a rotating rod is fixedly connected to one side of the adjusting block, a rotating plate is fixedly connected to one side of the rotating rod, a bearing is rotatably connected to the outer surface of the rotating rod, and the bearing is arranged inside one side of the oil inlet pipe.

When the three-ring reducer lacks lubrication, the friction between its internal gears, bearings and other components will increase significantly, which will not only cause energy loss, but also accelerate the wear of the components. At the same time, the heat cannot be dissipated in time, causing the temperature of the reducer to rise rapidly, which may cause thermal deformation and thermal cracks of the internal components.

[0014] Preferably, one end of the second rotating rod is fixedly connected to a driven wheel, one end of the driven wheel is rotatably connected to the inner wall of the reducer upper shell, and a synchronous belt is sleeved on the outer surface of the driven wheel, and the other end of the synchronous belt is sleeved on the driving wheel.

[0015] Preferably, a transmission rod is rotatably connected to the center of the inner cavity of the lower shell of the reducer, the outer surface of one end of the transmission rod is fixedly connected to the second transmission bevel gear, and the other end of the transmission rod is fixedly connected to the third transmission bevel gear, the outer surface of the transmission rod is fixedly connected to the driving wheel, an active rod is provided on one side of the transmission rod, and an output shaft is provided on the other side of the transmission rod, the outer surface of the output shaft is fixedly connected to the fourth transmission bevel gear, the fourth transmission bevel gear is meshingly connected with the third transmission bevel gear, the outer surface of the active rod is fixedly connected to the first transmission bevel gear, the first transmission bevel gear is meshingly connected with the second transmission bevel gear, and lubrication boxes are installed at the bottom of the second transmission bevel gear and the fourth transmission bevel gear.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the oil storage tank stores lubricating oil to ensure that the oil source is sufficient when the reducer is running. The rotating plate rotates with the machine, contacts the baffle and moves it upward, squeezes the spring, and the movement of the baffle drives the movable rod and the movable tube to connect the oil outlet with the discharge pipe, thereby replenishing the lubricating oil to the required position. After the rotating plate stops rotating, the baffle moves downward due to gravity and spring elastic force, disconnects the oil outlet from the discharge pipe, and stops replenishing the lubricating oil. This cycle process realizes the staged self-lubrication of the reducer, improves operating efficiency, prolongs service life, reduces maintenance costs and frequency, and can also play a role in cooling.

[0017] 2. In the present invention, when the oil storage tank moves down to below the lubricating oil level, the lubricating oil begins to be replenished to ensure that the internal parts of the lower housing of the reducer are sufficiently lubricated. The liquid level tube is convenient for observing the oil level. Once it is insufficient, it is replenished through the top inlet to keep the system in the best state. The driving wheel drives the driven wheel to rotate through the synchronous belt, and then drives the driving frame and the crank to perform circular motion through the second rotating rod. The pushing rod applies a force to the rotating frame in the pushing groove to rotate the first rotating rod. This transmission design makes the rotating plate rotate in stages, which not only ensures sufficient lubrication, but also avoids excessive replenishment. This precise lubrication control extends the system life and improves the stability and reliability of the equipment.

[0018] 3. In the present invention, the rotation of the active rod starts the key link of the lubrication system, driving the first transmission bevel gear to rotate. Through a specific transmission ratio, the first transmission bevel gear needs to rotate multiple times to drive the second transmission bevel gear to rotate one circle, ensuring the uniformity of lubrication. The second transmission bevel gear not only transmits power, but is also responsible for the distribution of lubricating oil, and cooperates with the discharge pipe to replenish the lubricating oil. When it rotates, part of the lubricating oil is thrown to the fourth transmission bevel gear, which is then transmitted to the third transmission bevel gear. This design ensures sufficient lubrication of each bevel gear, and through an appropriate transmission ratio, they rotate at the same speed, thereby improving the operating efficiency and life of the reducer. The entire lubrication process is automatic and efficient, which is an important guarantee for the stable operation of the reducer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described 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 creative work are within the scope of protection of the present invention.

[0022] Example 1: Reference Figure 1 - Figure 7As shown: a three-ring reducer for high temperature resistant self-lubricating roller rolling, comprising a reducer lower housing 3 and a reducer upper housing 2 fixedly connected to its top, an oil storage tank 1 fixedly connected to the upper part of the reducer upper housing 2, a lubrication mechanism 4 installed below the oil storage tank 1, and a transmission mechanism 6 installed inside the reducer upper housing 2; The lubrication mechanism 4 includes an oil storage tank 43 and a fixed sleeve 45, a movable tube 461 is slidably connected to the inner side of the fixed sleeve 45, a movable rod 46 is fixedly connected to the bottom of the movable tube 461, the top of the movable tube 461 passes through the fixed sleeve 45, and the top of the movable tube 461 is fixedly connected to the oil storage tank 43, the oil storage tank 43 is installed inside the oil storage box 1, the top of the fixed sleeve 45 is fixedly connected to the bottom of the oil storage box 1, the movable tube 461 is slidably connected to the oil storage box 1, the bottom of the movable rod 46 is fixedly connected to the baffle plate 42, and the bottom of the baffle plate 42 abuts against the rotating plate 41.

[0023] A discharge pipe 44 is fixedly connected to one side of the fixed sleeve 45, an oil outlet hole 463 is provided on one side of the movable pipe 461, and one end of the discharge pipe 44 passes through the upper housing 2 of the reducer. A discharge groove 462 is provided on the inner side of the movable pipe 461, and a spring 464 is installed between the fixed sleeve 45 and the baffle 42. The spring 464 is sleeved on the outer surface of the movable rod 46, and the diameter of the movable rod 46 is larger than the inner diameter of the fixed sleeve 45. An inlet 11 is provided on one side of the top of the oil storage tank 1, and a liquid level pipe 5 is fixedly connected to the bottom of one side of the oil storage tank 1.

[0024] In this embodiment, the oil storage tank 1 is a storage place for lubricating oil, which ensures that there is sufficient lubricating oil available during the operation of the reducer. When the reducer starts to work, the rotating plate 41 rotates with the rotation of the mechanical parts. The rotating plate 41 rotates around the central axis 411 and contacts the baffle 42 during the rotation.

[0025] As the rotating plate 41 rotates, it applies a force to the baffle 42. This force causes the baffle 42 to move upward, squeezing the spring 464 connected thereto. The spring 464 here acts as a buffer and reset, ensuring that the baffle 42 can return to its initial position after the rotating plate 41 stops rotating. When the baffle 42 moves upward, the movable rod 46 connected thereto will also move upward. The upward movement of the movable rod 46 drives the movable tube 461 to slide inside the fixed sleeve 45. This sliding process is critical because it controls the flow of lubricating oil. As the movable tube 461 moves upward, the oil outlet hole 463 thereon will align with and connect to the discharge pipe 44.

[0026] Once the oil outlet hole 463 is connected to the discharge pipe 44, the lubricating oil in the oil storage tank 43 will flow into the discharge pipe 44 through the discharge groove 462, and then be transported to the part that needs lubrication. This process realizes the automatic replenishment of the lubricating oil and ensures the smooth operation of the reducer.

[0027] When the rotating plate 41 stops rotating or the mechanical rotation reaches a certain stage, the baffle 42 drives the movable rod 46 and the movable tube 461 to move downward due to gravity and the elastic push of the spring 464. This downward movement disconnects the oil outlet 463 from the discharge tube 44, thereby stopping the replenishment of lubricating oil.

[0028] Through such a cycle, the lubrication system can periodically replenish lubricating oil for the reducer to achieve a self-lubricating effect. This not only improves the operating efficiency of the reducer, but also extends its service life. At the same time, this self-lubricating system also reduces the frequency of manual maintenance and reduces maintenance costs.

[0029] Embodiment 2: Figure 5 - Figure 7 As shown, the transmission mechanism 6 includes a first rotating rod 61 and a second rotating rod 64. One end of the first rotating rod 61 is rotatably connected to the inner wall of the upper housing 2 of the reducer, and the other end of the first rotating rod 61 is fixedly connected to a rotating frame 66. One end of the middle part of the rotating frame 66 is fixedly connected to the central shaft 411, and the central shaft 411 is fixedly connected to the inner surface of the rotating plate 41. One end of the second rotating rod 64 is fixedly connected to a driving frame 67. A crank 68 is fixedly connected to one side of the outer wall of the driving frame 67, and one end of the crank 68 is fixedly connected to a push rod 681. Three push grooves 661 are provided on the outer surface of the rotating frame 66, and the push grooves 661 are clamped with the push rod 681. One end of the second rotating rod 64 is fixedly connected to a driven wheel 65, and one end of the driven wheel 65 is rotatably connected to the inner wall of the upper housing 2 of the reducer, and a synchronous belt 63 is sleeved on the outer surface of the driven wheel 65, and the other end of the synchronous belt 63 is sleeved on the driving wheel 62.

[0030] In this embodiment, when the oil storage tank 43 moves downward to below the lubricating oil level in the oil storage tank 1, it starts the process of replenishing the lubricating oil. This process ensures that there is always enough lubricating oil in the oil storage tank 43 to meet the lubrication needs of the internal parts of the reducer lower housing 3.

[0031] Through the liquid level tube 5, the operator can easily observe the amount of lubricating oil in the oil storage tank 1. Once the lubricating oil is found to be insufficient, the operator can immediately replenish it through the feed port 11 at the top of the oil storage tank 1, thereby ensuring that the system is always in the best working condition.

[0032] In the power transmission part of the lubrication system, the driving wheel 62 is connected to the driven wheel 65 through the synchronous belt 63. When the driving wheel 62 rotates, the synchronous belt 63 transmits the power to the driven wheel 65, causing it to rotate as well. The rotation of the driven wheel 65 is then transmitted to the driving frame 67 through the second rotating rod 64. The rotation of the driving frame 67 drives the crank 68 to perform a circular motion. In this process, the push rod 681 enters the pushing groove 661 and exerts a force on the rotating frame 66. This force causes the rotating frame 66 to drive the first rotating rod 61 to rotate.

[0033] It is worth noting that the transmission design of the driving frame 67 and the rotating frame 66 makes the rotation of the rotating plate 41 phased. This design not only ensures that the internal parts of the reducer lower housing 3 can be fully lubricated, but also avoids the problem of excessive lubrication caused by continuous replenishment of lubricating oil. This precise lubrication control helps to extend the service life of the system and improve the stability and reliability of the equipment.

[0034] Embodiment 3: According to Figure 1 - Figure 4 As shown, a transmission rod 35 is rotatably connected to the center of the inner cavity of the lower housing 3 of the reducer, and the outer surface of one end of the transmission rod 35 is fixedly connected to the second transmission bevel gear 33, and the other end of the transmission rod 35 is fixedly connected to the third transmission bevel gear 34, and the outer surface of the transmission rod 35 is fixedly connected to the driving wheel 62, an active rod 31 is provided on one side of the transmission rod 35, and an output shaft 36 is provided on the other side of the transmission rod 35, and the outer surface of the output shaft 36 is fixedly connected to the fourth transmission bevel gear 37, and the fourth transmission bevel gear 37 is meshingly connected to the third transmission bevel gear 34, and the outer surface of the active rod 31 is fixedly connected to the first transmission bevel gear 32, and the first transmission bevel gear 32 is meshingly connected to the second transmission bevel gear 33, and the bottom of the second transmission bevel gear 33 and the fourth transmission bevel gear 37 are both installed with a lubrication box 38.

[0035] In this embodiment, the rotation of the active rod 31 directly drives the rotation of the first transmission bevel gear 32. This is an important starting point because it starts the first link of the lubrication system. Since there is a specific transmission ratio between the first transmission bevel gear 32 and the second transmission bevel gear 33, the first transmission bevel gear 32 needs to rotate multiple times to drive the second transmission bevel gear 33 to rotate one circle. This design ensures the uniformity and continuity of the lubrication process.

[0036] During the rotation process, the second transmission bevel gear 33 not only transmits power, but also undertakes the task of transmitting lubricating oil. When the discharge pipe 44 replenishes lubricating oil to the second transmission bevel gear 33, the lubricating oil will be evenly distributed on the tooth surface of the gear to form a protective film to reduce friction and wear between the gears.

[0037] When the second transmission bevel gear 33 rotates, it not only transfers the lubricating oil to the first transmission bevel gear 32 , but also throws part of the lubricating oil to the fourth transmission bevel gear 37 through centrifugal action.

[0038] Next, the fourth transmission bevel gear 37 continues to transfer the lubricating oil while also transferring it to the third transmission bevel gear 34. Since there is an appropriate transmission ratio between the fourth transmission bevel gear 37 and the third transmission bevel gear 34, they can be lubricated at the same rotation rate. This design ensures that all bevel gears involved in the transmission can be fully lubricated, thereby improving the operating efficiency and life of the reducer.

[0039] The use method and working principle of the device: During operation, the rotation of the active rod 31 will drive the first transmission bevel gear 32 to rotate synchronously. During this power transmission process, the first transmission bevel gear 32 will drive the second transmission bevel gear 33 to rotate with its specific transmission ratio, so that the second transmission bevel gear 33 rotates one circle after the first transmission bevel gear 32 rotates multiple circles. This design ensures that the rotation rate of the third transmission bevel gear 34 matches that of the second transmission bevel gear 33.

[0040] While rotating, the second transmission bevel gear 33 receives the lubricating oil replenished from the discharge pipe 44, and transfers the lubricating oil to the first transmission bevel gear 32 through the rotation action, and also throws part of the lubricating oil to the fourth transmission bevel gear 37, thereby achieving lubrication of the first transmission bevel gear 32, the second transmission bevel gear 33 and the fourth transmission bevel gear 37. Afterwards, the fourth transmission bevel gear 37 transfers the lubricating oil to the third transmission bevel gear 34, ensuring that all transmission bevel gears are fully lubricated.

[0041] In order to maintain the supply of lubricating oil, the oil storage tank 43 will be moved below the lubricating oil level in the oil storage tank 1, so as to automatically replenish the lubricating oil. The liquid level of the oil storage tank 1 can be observed through the liquid level tube 5. When the amount of lubricating oil is insufficient, it can be replenished through the feed port 11 at the top of the oil storage tank 1.

[0042] During the process of replenishing lubricating oil, the driving wheel 62 drives the driven wheel 65 to rotate through the synchronous belt 63. The rotational force of the driven wheel 65 is transmitted to the driving frame 67 through the second rotating rod 64, causing it to rotate. As the driving frame 67 rotates, the crank 68 performs a circular motion with the second rotating rod 64 as the center. Under the push of the crank 68, the push rod 681 enters the push groove 661, exerts a force on the rotating frame 66, and then drives the first rotating rod 61 to rotate. This rotation action will eventually drive the discharge pipe 44 to rotate.

[0043] By utilizing the transmission mechanism of the driving frame 67 and the rotating frame 66, the rotation of the rotating plate 41 is staged, thereby realizing the staged replenishment of the lubricating oil. This design ensures the normal operation of the internal parts of the reducer lower housing 3, and also avoids the problem of excessive replenishment of the lubricating oil.

[0044] Inside the oil storage tank 1, when the rotating plate 41 rotates around the central axis 411, it comes into contact with the baffle 42 and exerts a force. This force causes the movable rod 46 to start moving upward, while compressing the spring 464. As the movable rod 46 rises, the movable tube 461 slides inside the fixed sleeve 45 until the oil outlet hole 463 is connected to the discharge pipe 44. At this time, the lubricating oil in the oil storage tank 43 flows into the discharge pipe 44 through the discharge groove 462, completing the replenishment of the lubricating oil. When the rotating plate 41 stops rotating, the movable rod 46 and its related structures return to their original positions under the action of gravity and the elastic force of the spring 464, disconnecting from the discharge groove 462 and the oil outlet hole 463, and stopping the replenishment of the lubricating oil. The entire process realizes the staged replenishment of the lubricating oil and ensures the effective operation of the self-lubricating system.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
