Description

Technical Field

[0001] The invention relates to the technical field of alloy gear sets, in particular to an alloy gear set with a self-lubricating effect. Background Art

[0002] Alloy gear sets are gear combinations made of alloy materials composed of multiple metal elements, usually containing two or more meshing gears. Through the meshing transmission between the teeth of the gears, power transmission, speed change and torque conversion are realized. They have good toughness, corrosion resistance and low noise characteristics, low density, high elastic modulus, easy processing and molding, and are suitable for manufacturing gears with complex shapes. However, their hardness and strength are relatively low, and they are easy to wear. They are not suitable for high torque and high load conditions. Factors such as transmission ratio, torque, speed, and load distribution need to be considered to determine the gear module, number of teeth, tooth width, helix angle and other parameters. At the same time, the overall structural design such as the gear layout and shaft support method must also be considered to ensure the transmission efficiency and stability of the gear set.

[0003] The patent network announcement number CN 208281458 U discloses a gear, whose gear teeth include a tooth core and a rotating sleeve sleeved outside the tooth core, the tooth core and the wheel disc of the gear are integrally formed, the rotating sleeve is provided with a first mechanism, the tooth core is provided with a second mechanism, the first mechanism and the second mechanism are matched, so that the rotating sleeve can rotate coaxially relative to the tooth core. The gear of the present application has a relatively rotatable double-layer structure with gear teeth, which is suitable for the valve stem lifting performance test of indoor fire hydrants, can reduce the interference friction during the detection process, and make the test results accurate.

[0004] The applicant believes that the gear has the following disadvantages: the gear does not have the function of self-lubrication during rotation, which increases the wear of the tooth surface during high-speed rotation and frequent meshing, reduces the service life of the gear, and has defects. Summary of the invention

[0005] The object of the present invention is to provide an alloy gear set with self-lubricating effect to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: an alloy gear set with self-lubricating effect, comprising a housing, a working mechanism is arranged inside the housing, an oil outlet mechanism is arranged on the surface of the working mechanism, and an adjustment mechanism is arranged on the outer surface of the housing.

[0007] The oil outlet mechanism includes a fixed bearing, which is fixedly connected to the surface of the shell, the inner ring of the fixed bearing is fixedly connected to the output shaft, the surface of the output shaft is fixedly connected to the first large gear, the surface of the first large gear is provided with an oil outlet groove, a blocking plate is inserted in the oil outlet groove, the bottom of the blocking plate is fixedly connected to a support seat, and the first large gear is provided with an oil placement groove, which is designed in a ring shape.

[0008] Preferably, the support seat is fixedly connected with a cross plate on both sides, a support piece is fixedly connected between the two cross plates, a support rod is slidably connected in the support piece, and the support rod is fixedly connected to the top of the support seat. In the mechanical transmission system, when the support seat starts to move, its internal structure design ensures the stability of the entire process. A high-precision sliding matching structure is adopted between the support piece and the support rod. The support piece fits tightly on the surface of the support rod. As the support seat moves, the support piece slides smoothly along the axial direction of the support rod. This sliding process is not a simple linear displacement. The sliding surface of the support piece has been finely polished and is compatible with the support The surface roughness of the support rod reaches the micron level, which greatly reduces the friction resistance during the sliding process. At the same time, a special guiding structure is designed inside the support part, so that the support part can always maintain coaxiality with the support rod when sliding, avoiding deviation or shaking. The advantage of this structural design is that no matter whether the support base is moving quickly or adjusting its position slowly, the support part can slide stably on the surface of the support rod, thereby providing reliable support and guiding for the support base, ensuring the stability of the support base during the entire movement process, and effectively avoiding equipment failure or precision loss caused by shaking or deviation.

[0009] Preferably, a vertical rod is slidably connected inside the horizontal plate, a limit plate is fixedly connected to the top of the vertical rod, the limit plate is arranged on the top of the support seat, a connecting plate is fixedly connected to the bottom of the vertical rod, a first fixed plate is fixedly connected to the bottom of the connecting plate, the first fixed plate is fixedly connected to the oil tank, and in this device, a carefully designed limit plate is specially arranged. Its unique structure and installation position enable it to accurately limit the vertical rod. When the vertical rod performs relevant movements inside the horizontal plate, the limit plate is like a loyal guard, always playing its key role. It closely cooperates with the specific parts of the vertical rod to limit the displacement range of the vertical rod from a physical level, effectively preventing the vertical rod from falling off inside the horizontal plate due to various factors, such as vibration, external force impact, etc., thereby ensuring the stability and safety of the entire device.

[0010] Preferably, a spring is sleeved on the surface of the vertical rod, and the spring is arranged between the horizontal plate and the connecting plate. The number of the horizontal plates is two, and the two horizontal plates are arranged symmetrically. In mechanical systems, the elastic potential energy characteristics of the spring are often used. When the spring is stretched or compressed, it will store elastic potential energy. Based on this characteristic, when the spring is connected to the blocking plate, once the external action is released, the spring generates a restoring force by virtue of its own stored elastic potential energy, thereby achieving the purpose of resetting the blocking plate.

[0011] Preferably, the adjustment mechanism includes an internal spline, the internal spline is inserted into the output shaft, the surface of the internal spline is rotatably connected with a connector, the bottom of the connector is fixedly connected with a second fixed plate, the second fixed plate is slidably connected with a connecting rod, and the connecting rod is fixedly connected to the surface of the shell. In a complex mechanical transmission structure, the output shaft plays a key role in power transmission. When the internal spline slides inside the output shaft, the stability of its movement process has an important impact on the performance of the entire transmission system. At this time, the cooperation between the second fixed plate and the connecting rod plays a key role. The second fixed plate fits tightly on the surface of the connecting rod and slides synchronously on the surface of the connecting rod as the internal spline slides. This structural design can constrain and support the movement of the internal spline from multiple directions, effectively avoiding the internal spline from shaking, deflecting and other unstable phenomena during the sliding process, thereby ensuring the stability of the internal spline during movement, and laying a solid foundation for the reliable operation of the entire mechanical transmission system.

[0012] Preferably, a mounting plate is fixedly connected to the surface of the shell, a placement plate is fixedly connected to the side of the mounting plate facing away from the shell, a cylinder is fixedly connected between the placement plate and the connecting piece, two cylinders are arranged symmetrically, the cylinder serves as a power source, the piston inside the cylinder generates a linear motion under the push of air pressure, and then drives the connecting piece to move precisely through a specific connecting mechanism, and in this process, the internal spline tightly connected to the connecting piece will slide smoothly along the spline groove inside the output shaft.

[0013] Preferably, the working mechanism includes a first pinion, which is meshed with the surface of a first large gear. The inner ring of the first pinion is fixedly connected to a first support shaft, the surface of the first support shaft is fixedly connected to a second large gear, and the surface of the second large gear is meshed with a third pinion.

[0014] Preferably, the inner ring of the third pinion is fixedly connected to the second supporting shaft, the surface of the second supporting shaft is fixedly connected to the third large gear, the surface of the third large gear is meshed with the second pinion, the inner ring of the second pinion is fixedly connected to the connecting shaft, the surface of the connecting shaft is fixedly connected to the bearing, and the bearing is fixedly connected to the surface of the shell. The first large gear starts to rotate under the action of torque. Since the first large gear and the first pinion are meshed with each other, the rotation of the first large gear will drive the first pinion to rotate at high speed. At the same time, the first pinion is synchronously meshed with the second large gear and the third pinion, thereby driving the second large gear and the third pinion to rotate synchronously, and the third large gear and the second pinion are also in a meshing state. Their synchronous rotation ultimately achieves the purpose of efficient workmanship of the alloy gear set and converts the input power into various forms of mechanical motion to meet the working requirements of different mechanical equipment.

[0015] Compared with the prior art, the present invention provides an alloy gear set with self-lubricating effect, which has the following beneficial effects: 1. Under the action of gravity, the self-lubricating alloy gear set will evenly flow to the surface of the first large gear through the pre-designed oil outlet groove. The lubricating oil will quickly spread on the gear surface to form a uniform and stable oil film. This oil film is like an invisible protective film, separating the metal surface of the gear, so that the friction between the tooth surfaces changes from the original dry friction to oil film friction. This change in friction form greatly reduces the friction coefficient and significantly reduces the wear of the tooth surface during high-speed rotation and frequent meshing, effectively extending the service life of the gear and ensuring the stable operation of the alloy gear set under long-term and high-intensity working conditions.

[0016] 2. This self-lubricating alloy gear set uses the cylinder as the power source. The piston inside it produces linear motion under the push of air pressure, and then drives the connecting parts to move precisely through a specific connection mechanism. In this process, the internal spline closely connected to the connecting parts will slide smoothly along the spline groove inside the output shaft. This ingeniously designed sliding connection method allows the length of the output shaft to be accurately adjusted according to actual needs, greatly enhancing the applicability and flexibility of the equipment and meeting the use needs in various complex working scenarios.

[0017] 3. In the alloy gear set with self-lubricating effect, the first small gear is synchronously meshed with the second large gear and the third small gear, thereby driving the second large gear and the third small gear to rotate synchronously, and the third large gear is also in a meshing state with the second small gear. Their synchronous rotation ultimately achieves the purpose of efficient workmanship of the alloy gear set, converting the input power into various forms of mechanical motion to meet the working requirements of different mechanical equipment.

DETAILED DESCRIPTION

[0020] 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 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 creative work are within the scope of protection of the present invention.

[0021] The present invention provides a technical solution: Embodiment 1:

[0022] Combination Figure 1-2 to Figure 3-5An alloy gear set with self-lubricating effect comprises a housing 1, a working mechanism 4 is arranged inside the housing, an oil outlet mechanism 2 is arranged on the surface of the working mechanism 4, and an adjusting mechanism 3 is arranged on the outer surface of the housing 1.

[0023] The oil outlet mechanism 2 includes a fixed bearing, which is fixedly connected to the surface of the housing 1. The inner ring of the fixed bearing is fixedly connected to the output shaft. The surface of the output shaft is fixedly connected to the first large gear 202. The surface of the first large gear 202 is provided with an oil outlet groove. A blocking plate 24 is inserted in the oil outlet groove. A support seat 29 is fixedly connected to the bottom of the blocking plate 24. An oil placement groove is provided in the first large gear 202, and the oil placement groove is designed in a ring shape.

[0024] Furthermore, both sides of the support seat 29 are fixedly connected with cross plates 28, a support member 26 is fixedly connected between the two cross plates 28, a support rod 25 is slidably connected inside the support member 26, and the support rod 25 is fixedly connected to the top of the support seat 29. In the mechanical transmission system, when the support seat 29 starts to move, its internal structural design ensures the stability of the entire process. A high-precision sliding matching structure is adopted between the support member 26 and the support rod 25. The support member 26 fits tightly on the surface of the support rod 25. As the support seat 29 moves, the support member 26 slides smoothly along the axial direction of the support rod 25. This sliding process is not a simple linear displacement. The sliding surface of the support member 26 has been finely polished. The surface roughness of the support rod 25 is matched to the micron level, which greatly reduces the friction resistance during the sliding process. At the same time, a special guiding structure is designed inside the support member 26, so that the support member 26 can always maintain coaxiality with the support rod 25 when sliding, avoiding deviation or shaking. The advantage of this structural design is that no matter the support seat 29 is moving quickly or adjusting its position slowly, the support member 26 can slide stably on the surface of the support rod 25, thereby providing reliable support and guiding for the support seat 29, ensuring the stability of the support seat 29 during the entire movement process, and effectively avoiding equipment failure or precision reduction problems that may be caused by shaking or deviation.

[0025] Furthermore, the vertical rod 21 is slidably connected in the horizontal plate 28, and the top of the vertical rod 21 is fixedly connected to a limiting plate 27, which is arranged on the top of the support seat 29, and the bottom of the vertical rod 21 is fixedly connected to a connecting plate 201, and the bottom of the connecting plate 201 is fixedly connected to a first fixing plate 22, which is fixedly connected to the oil tank. In this device, a carefully designed limiting plate 27 is specially arranged. Its unique structure and installation position enable it to accurately limit the vertical rod 21. When the vertical rod 21 performs relevant movements inside the horizontal plate 28, the limiting plate 27 is like a loyal guard, always playing its key role. It closely cooperates with the specific part of the vertical rod 21 to limit the displacement range of the vertical rod 21 from a physical level, effectively preventing the vertical rod 21 from falling off inside the horizontal plate 28 due to various factors, such as vibration, external force impact, etc., thereby ensuring the stability and safety of the entire device.

[0026] Furthermore, a spring 23 is sleeved on the surface of the vertical rod 21. The spring 23 is arranged between the horizontal plate 28 and the connecting plate 201. There are two horizontal plates 28, and the two horizontal plates 28 are arranged symmetrically. In the mechanical system, the elastic potential energy characteristics of the spring 23 are often used. When the spring 23 is stretched or compressed, the elastic potential energy is stored. Based on this characteristic, when the spring 23 is connected to the blocking plate 24, once the external action is released, the spring 23 generates a restoring force by virtue of its own stored elastic potential energy, thereby achieving the purpose of resetting the blocking plate 24. Embodiment 2:

[0027] See also Figure 6 , and on the basis of the first embodiment, the adjustment mechanism 3 further comprises an inner spline 35, the inner spline 35 is inserted into the output shaft, the surface of the inner spline 35 is rotatably connected with a connector 36, the bottom of the connector 36 is fixedly connected with a second fixed plate 32, the second fixed plate 32 is slidably connected with a connecting rod 37, and the connecting rod 37 is fixedly connected to the surface of the housing 1. In the complex mechanical transmission structure, the output shaft plays a key role in power transmission. When the inner spline 35 slides inside the output shaft, the stability of its movement process has an important influence on the performance of the entire transmission system. At this time, the cooperation between the second fixed plate 32 and the connecting rod 37 plays a key role. The second fixed plate 32 fits tightly on the surface of the connecting rod 37, and slides synchronously on the surface of the connecting rod 37 as the inner spline 35 slides. This structural design can constrain and support the movement of the inner spline 35 from multiple directions, effectively avoiding the inner spline 35 from shaking, deflecting and other unstable phenomena during the sliding process, thereby ensuring the stability of the inner spline 35 during the movement process, and laying a solid foundation for the reliable operation of the entire mechanical transmission system.

[0028] Furthermore, a mounting plate 31 is fixedly connected to the surface of the shell 1, a placement plate 34 is fixedly connected to the side of the mounting plate 31 facing away from the shell 1, a cylinder 33 is fixedly connected between the placement plate 34 and the connecting member 36, two cylinders 33 are arranged, and the two cylinders 33 are symmetrically arranged. The cylinder 33 serves as a power source, and the piston inside it generates a linear motion under the push of air pressure, and then drives the connecting member 36 to move precisely through a specific connecting mechanism. In this process, the internal spline 35 tightly connected to the connecting member 36 will slide smoothly along the spline groove inside the output shaft. Embodiment three:

[0029] See also Figure 7 On the basis of the first and second embodiments, the working mechanism 4 further comprises a first pinion 43, the first pinion 43 is meshed with the surface of the first large gear 202, the inner ring of the first pinion 43 is fixedly connected with the first support shaft 42, the surface of the first support shaft 42 is fixedly connected with the second large gear 41, and the surface of the second large gear 41 is meshed with the third pinion 48.

[0030] Furthermore, the inner ring of the third pinion 48 is fixedly connected to the second support shaft 47, the surface of the second support shaft 47 is fixedly connected to the third large gear 46, the surface of the third large gear 46 is meshed with the second pinion 45, the inner ring of the second pinion 45 is fixedly connected to the connecting shaft, the surface of the connecting shaft is fixedly connected to the bearing 44, the bearing 44 is fixedly connected to the surface of the housing 1, and the first large gear 202 starts to rotate under the action of torque. Since the first large gear 202 and the first pinion 43 are meshed with each other, the rotation of the first large gear 202 will drive the first pinion 43 to rotate at high speed. At the same time, the first pinion 43 is synchronously meshed with the second large gear 41 and the third pinion 48, thereby driving the second large gear 41 and the third pinion 48 to rotate synchronously, and the third large gear 46 and the second pinion 45 are also in a meshing state. Their synchronous rotation ultimately achieves the purpose of efficient workmanship of the alloy gear set, converting the input power into various forms of mechanical motion to meet the working requirements of different mechanical equipment.

[0031] In actual operation, in a mechanical transmission system, flexible adjustment of the output shaft length is very important. When the actual working conditions have different requirements for the output shaft length, the operator only needs to start the cylinder 33. The cylinder 33 serves as a power source, and the piston inside it generates linear motion under the push of air pressure, and then drives the connector 36 to move precisely through a specific connection mechanism. In this process, the internal spline 35 closely connected to the connector 36 will slide smoothly along the spline groove inside the output shaft. This ingeniously designed sliding connection method enables the length of the output shaft to be accurately adjusted according to actual needs, greatly enhancing the applicability and flexibility of the equipment and meeting the use requirements in various complex working scenarios. When the alloy gear set needs to be put into operation, the output shaft must first be reliably connected to an external drive source. The external drive source can be a power device such as a motor or an engine, which can provide stable and strong power output. After the connection is completed, the drive source is started, and the torque output by the drive source is transmitted to the alloy gear set through the output shaft. At this time, the first large gear 202 starts to rotate under the action of the torque. Since the first large gear 202 and the first small gear 43 are meshed with each other, the rotation of the first large gear 202 will drive the first small gear 43 to rotate at a high speed. At the same time, the first small gear 43 is synchronously meshed with the second large gear 41 and the third small gear 48, thereby driving the second large gear 41 and the third small gear 48 to rotate synchronously, and the third large gear 46 is also in meshing state with the second small gear 45. Their synchronous rotation ultimately achieves the purpose of efficient workmanship of the alloy gear set, converting the input power into various forms of mechanical motion to meet the working requirements of different mechanical equipment; During the continuous rotation of the first large gear 202 and the first small gear 43, there is an ingenious lubrication control mechanism. When the teeth on the surface of the first small gear 43 contact the gap of the first large gear 202, the teeth will exert an extrusion force on the blocking plate 24. The blocking plate 24 is connected to the cross plate 28 through a specific connection structure. Under the action of the extrusion force, the cross plate 28 will overcome its own gravity and friction and slide smoothly downward on the surface of the vertical rod 21. As the cross plate 28 slides down, the support seat 29 that was originally in close contact with the top of the oil tank will gradually detach, which breaks the sealing state of the oil tank and the inside of the oil tank is Under the action of gravity, the stored lubricating oil will flow evenly to the surface of the first large gear 202 through the pre-designed oil outlet groove, and the lubricating oil will quickly spread on the gear surface to form a uniform and stable oil film. This oil film is like an invisible protective film, separating the metal surface of the gear, and changing the friction between the tooth surfaces from the original dry friction to oil film friction. This change in friction form greatly reduces the friction coefficient and significantly reduces the wear of the tooth surface during high-speed rotation and frequent meshing, effectively extending the service life of the gear and ensuring the stable operation of the alloy gear set under long-term and high-intensity working conditions.
