Description

Technical Field

[0001] This invention relates to the field of cylinder lubrication technology, and more particularly to a piston cylinder lubrication device. Background Technology

[0002] The lubrication system of a piston cylinder is a key component ensuring its efficient and stable operation. High-frequency relative motion exists between the piston and cylinder wall, and between the piston rings and cylinder wall. The lubrication system delivers lubricating oil to the friction surfaces, forming an oil film. This oil film separates the metal surfaces, reducing wear on components and extending the service life of the cylinder, piston, and piston rings. Through its four core functions—lubrication, sealing, cooling, and corrosion prevention—the lubrication system of a piston cylinder directly affects the operating efficiency, service life, and reliability of the equipment, making it an indispensable part of piston machinery. In different application scenarios, the type of lubrication system and the selection of lubricating oil will be adjusted according to requirements to ensure optimal results.

[0003] The existing Chinese patent publication number is CN107477045A, entitled "Piston-type Cylinder Lubrication Device." This invention discloses a piston-type cylinder lubrication device, including a cylinder body, piston, piston rod, piston fixing block, rotating shaft, motor, rotating shaft fixing column, air inlet, air outlet, and air pipe. The bottom of the cylinder body has an oil storage chamber. An elastic sleeve is spirally fixed between the piston fixing block and the oil storage chamber, and the piston fixing block and oil storage chamber are connected by the elastic sleeve. An integrated pipe is provided inside the piston, piston rod, and piston fixing block. Oil-absorbing cotton is provided inside the oil storage chamber, extending into and filling the entire pipe. This piston-type cylinder lubrication device can lubricate the piston and cylinder body simultaneously during piston movement, eliminating the need for external lubrication, simplifying the lubrication process, and avoiding leakage or insufficient output force due to insufficient lubrication supply.

[0004] However, the above solution does not include a structure that adjusts the fuel injection quantity according to engine speed, and cannot accurately match lubrication requirements under different operating conditions. If the fuel injection quantity is fixed and designed for high-speed requirements, it will lead to excessive lubricating oil at low speeds. The excess lubricating oil will be burned, producing carbon deposits, reducing engine efficiency, and even causing knocking. The unburned lubricating oil will be discharged with the exhaust gas, increasing exhaust pollutants. When the engine is running at high speed, the relative speed between the piston and the cylinder wall increases significantly, friction intensifies, and the heat generated increases sharply. If sufficient lubricating oil cannot carry away more heat, it cannot help cool the friction parts, leading to local overheating and material failure, increasing the risk of overheating. It cannot guarantee sufficient lubrication at high speeds to reduce wear and cope with high temperatures, ultimately failing to achieve high efficiency, durability, and environmental friendliness of the engine. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art, such as the inability to accurately match lubrication requirements under different operating conditions. If the oil injection volume is fixed and designed for high-speed requirements, excessive lubricating oil will occur at low speeds. The excess lubricating oil will be burned, producing carbon deposits, reducing engine efficiency, and even causing knocking. The unburned lubricating oil will be discharged with the exhaust gas, increasing exhaust pollutants. When the engine is running at high speed, the relative speed between the piston and the cylinder wall increases significantly, friction intensifies, and the heat generated increases sharply. If sufficient lubricating oil cannot remove more heat, it cannot help cool the friction parts, leading to local overheating and material failure, increasing the risk of overheating. It is impossible to ensure sufficient lubrication at high speeds to reduce wear and cope with high temperatures, ultimately achieving high efficiency, durability, and environmental protection in the engine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a piston-type cylinder lubrication device, comprising: a bottom shell, a top shell disposed on the top of the bottom shell, a cylinder connected to the top of the top shell, a power output rod rotatably connected to the inner side of the bottom shell and the top shell, a rod sleeve rotatably connected to the outer side of the power output rod, a main connecting rod fixedly connected to the top of the rod sleeve, a shaft block rotatably connected to the end of the main connecting rod away from the rod sleeve, a piston fixedly connected to the top of the shaft block, and the outer side of the piston movably embedded in the inner surface of the cylinder; A linkage component is provided on the outer side of the power output rod; A lubrication assembly is provided at the bottom of the base shell.

[0007] The technical effect of adopting the above-mentioned further solution is that, under the action of fuel compression and combustion, the power piston will be driven to move up and down on the inner wall of the cylinder. When the piston moves, it will drive one end of the main connecting rod through the shaft block. The other end of the main connecting rod will drive the rod sleeve, so that the power output rod rotates inside the bottom shell and the top shell and realizes power output.

[0008] In a preferred embodiment, the linkage assembly includes a driving bevel gear, which is fixedly sleeved on the outside of the power output rod. A driven bevel gear is meshed with the outside of the driving bevel gear. An internal hexagonal sleeve is fixedly connected to the bottom of the driven bevel gear. A protective shell is rotatably connected to the outside of the internal hexagonal sleeve. The top of the protective shell is fixedly connected to the inner surface of the top shell. The outside of the power output rod is rotatably connected to both sides of the protective shell.

[0009] The technical effect of adopting the above-mentioned further solution is that the active bevel gear, which rotates with the power output rod, will drive the internal hexagon sleeve to rotate at the bottom of the protective shell under the meshing action of the driven bevel gear.

[0010] In a preferred embodiment, a hexagonal block is movably embedded in the inner surface of the internal hexagonal sleeve, a main rod is fixedly connected to the bottom of the hexagonal block, a stabilizing sleeve is rotatably connected to the outer side of the main rod, and the bottom of the stabilizing sleeve is fixedly connected to the inner surface of the bottom shell.

[0011] The technical effect of adopting the above-mentioned further solution is that the main rod that follows the rotation of the hexagonal block will rotate inside the stabilizing sleeve.

[0012] In a preferred embodiment, centrifugal rods are rotatably connected to both sides of the main rod, a centrifugal ball is fixedly connected to the bottom of the centrifugal rod, a second connecting rod is rotatably connected to the end of the centrifugal rod away from the centrifugal ball, a shaft plate is rotatably connected to the end of the second connecting rod away from the centrifugal rod, and a movable sleeve is fixedly connected to the inner side of the two shaft plates.

[0013] The technical effect of adopting the above-mentioned further solution is that the centrifugal rod and centrifugal ball that follow the main rod will be driven by the centrifugal force to spread outward.

[0014] In a preferred embodiment, the movable sleeve is movably fitted onto the outside of the main rod, and a force-bearing sleeve is fixedly connected to the top of the movable sleeve, which is movably fitted onto the outside of the main rod.

[0015] The technical effect of adopting the above-mentioned further solution is that the moving sleeve and the force-bearing sleeve move longitudinally along the axis of the main rod.

[0016] In a preferred embodiment, a fixing rod is fixedly connected to the inner surface of the bottom shell, a shaft is rotatably connected inside the fixing rod, a rocker arm is fixedly sleeved on the outer side of the shaft, a double fork is fixedly connected to the end of the rocker arm near the main rod, the inner side of the double fork is set inside the force-bearing sleeve, and a slot is opened at the end of the rocker arm away from the double fork.

[0017] The technical effect of adopting the above-mentioned further solution is that its double fork design allows the double fork to have a certain radial displacement inside the force-bearing sleeve, so that the double fork will not detach from the force-bearing sleeve due to angular deviation in the direction of relative movement.

[0018] In a preferred embodiment, the lubrication assembly includes an oil reservoir, the top of which is connected to the bottom of a base shell, and the bottom of which is connected to an oil drain pipe with a pipe cap threaded to the bottom.

[0019] The technical effect of adopting the above-mentioned further solution is that the oil inside the oil reservoir can be drained through the drain pipe by rotating the pipe cover.

[0020] In a preferred embodiment, an oil suction pipe is fixedly connected to the inner surface of the oil storage shell, and the bottom of the oil suction pipe has multiple oil inlets. The outer side of the oil suction pipe is fixedly embedded in one side of the bottom shell.

[0021] The technical effect of adopting the above-mentioned further solution is that the oil pump that works in real time will generate suction inside the oil suction pipe, and the oil will enter the oil suction pipe through the oil inlet.

[0022] In a preferred embodiment, an extension rod is rotatably connected inside the oil suction pipe and extends out to one end. A valve plate is fixedly sleeved on the outer side of the extension rod. A crank is fixedly connected to the end of the extension rod away from the valve plate. A connecting rod is fixedly connected inside the crank. The outer side of the connecting rod is disposed inside the groove.

[0023] The technical effect of adopting the above-mentioned further solution is that the groove at the other end of the rocker arm will drive the connecting rod. The groove is larger than the outer surface of the connecting rod. The groove allows a certain radial displacement inside, so that the circumferential movement in two directions will not interfere with each other. This drives the crank, the extension rod and the oil valve plate to swing in the direction of the extension rod axis, changing the inner diameter of the oil suction pipe and the oil suction volume of the oil pump.

[0024] In a preferred embodiment, one end of the oil suction pipe is connected to an oil pump, one side of the oil pump is fixedly connected to one side of the bottom housing, the side of the oil pump near the bottom housing is connected to an oil outlet pipe, the outer side of the oil outlet pipe is fixedly embedded inside the bottom housing, and the outer side of the oil outlet pipe is connected to a nozzle.

[0025] The technical effect of adopting the above-mentioned further solution is that the oil pump that works in real time will generate suction inside the oil suction pipe, and the oil will enter the oil suction pipe through the oil inlet. Under the pressure of the oil pump, it will flow through the oil outlet pipe and finally be sprayed out by the nozzle, thus lubricating the inner wall of the cylinder.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this embodiment of the invention, the amount of lubricating oil injected at low speed can be reduced, avoiding the excess lubricating oil from being burned and producing carbon deposits, improving engine efficiency, avoiding knocking, and the unburned lubricating oil will be discharged with the exhaust gas, reducing exhaust pollutants.

[0027] 2. In this embodiment of the invention, when the engine is running at high speed, the relative speed between the piston and the cylinder wall increases significantly, and the friction intensifies. Sufficient lubricating oil can carry away more heat, assist in cooling the friction parts, avoid material failure caused by local overheating, reduce the risk of overheating, ensure sufficient lubrication at high speed to reduce wear and cope with high temperature, and ultimately achieve high efficiency, durability and environmental protection of the engine.

[0032] When in use, the fuel compression and combustion will drive the power piston 8 to move up and down on the inner wall of the cylinder 3. When the piston 8 moves, it will drive one end of the main connecting rod 6 through the shaft block 7. The other end of the main connecting rod 6 will drive the rod sleeve 5, so that the power output rod 4 will rotate inside the bottom shell 1 and the top shell 2 and realize power output.

[0033] like Figures 1 to 8 As shown, in one embodiment, the linkage component includes a driving bevel gear 9, which is fixedly sleeved on the outside of the power output rod 4. A driven bevel gear 10 is meshed with the outside of the driving bevel gear 9. An internal hexagonal sleeve 11 is fixedly connected to the bottom of the driven bevel gear 10. A protective shell 12 is rotatably connected to the outside of the internal hexagonal sleeve 11. The top of the protective shell 12 is fixedly connected to the inner surface of the top shell 2. The outside of the power output rod 4 is rotatably connected to both sides of the protective shell 12. The driving bevel gear 9, which rotates with the power output rod 4, will drive the internal hexagonal sleeve 11 to rotate at the bottom of the protective shell 12 under the meshing action of the driven bevel gear 10.

A main rod 14 is fixedly connected to the bottom of the hexagonal block 13. A stabilizing sleeve 15 is rotatably connected to the outer side of the main rod 14. The bottom of the stabilizing sleeve 15 is fixedly connected to the inner surface of the bottom shell 1. When the internal hexagonal sleeve 11 rotates at the bottom of the protective shell 12, it will drive the internal hexagonal block 13.

[0035] like Figures 1 to 8 As shown, in one embodiment, centrifugal rods 16 are rotatably connected to both sides of the main rod 14. A centrifugal ball 17 is fixedly connected to the bottom of the centrifugal rod 16.

The other end of the second connecting rod 18 will pull the movable sleeve 20 through the shaft plate 19.

[0036] like Figures 1 to 8 As shown, in one embodiment, the movable sleeve 20 is movably sleeved on the outside of the main rod 14, and a force-bearing sleeve 21 is fixedly connected to the top of the movable sleeve 20. The force-bearing sleeve 21 is movably sleeved on the outside of the main rod 14, so that the movable sleeve 20 and the force-bearing sleeve 21 move longitudinally along the axial direction of the main rod 14.

[0037] like Figures 1 to 8 As shown, in one embodiment, a fixing rod 22 is fixedly connected to the inner surface of the bottom shell 1. A shaft 23 is rotatably connected inside the fixing rod 22. A rocker arm 24 is fixedly sleeved on the outer side of the shaft 23. A double fork 25 is fixedly connected to one end of the rocker arm 24 near the main rod 14. The inner side of the double fork 25 is located inside the force-bearing sleeve 21. A slot 26 is opened at the end of the rocker arm 24 away from the double fork 25. The design of the double fork 25 allows the double fork 25 to have a certain radial displacement inside the force-bearing sleeve 21, so that the double fork 25 will not detach from the inside of the force-bearing sleeve 21 due to angular deviation in the direction of relative movement.

[0038] like Figures 1 to 8 As shown, in one embodiment, the lubrication assembly includes an oil reservoir 27, the top of which is connected to the bottom of the bottom shell 1, and the bottom of which is connected to an oil drain pipe 28. The bottom of the oil drain pipe 28 is threadedly connected to a pipe cap 29. The oil inside the oil reservoir 27 can be opened by rotating the pipe cap 29, and the oil inside the oil reservoir 27 will flow out through the oil drain pipe 28.

[0039] like Figures 1 to 8 As shown, in one embodiment, an oil suction pipe 30 is fixedly connected to the inner surface of the oil reservoir 27. The bottom of the oil suction pipe 30 is provided with multiple oil inlets 31. The outer side of the oil suction pipe 30 is fixedly embedded on one side of the bottom shell 1. The engine oil will enter the oil suction pipe 30 through the oil inlets 31.

[0040] like Figures 1 to 8 As shown, in one embodiment, an extension rod 32 is rotatably connected inside the oil suction pipe 30 and extends out one end. A valve plate 33 is fixedly sleeved on the outside of the extension rod 32. A crank 34 is fixedly connected to the end of the extension rod 32 away from the valve plate 33. A connecting rod 35 is fixedly connected inside the crank 34. The outside of the connecting rod 35 is set inside the slot 26. The slot 26 at the other end of the rocker arm 24 will drive the connecting rod 35. The slot 26 is larger than the outer surface of the connecting rod 35. The slot 26 allows a certain radial displacement inside.

[0041] like Figures 1 to 8As shown, in one embodiment, one end of the oil suction pipe 30 is connected to an oil pump 36. One side of the oil pump 36 is fixedly connected to one side of the bottom housing 1. The side of the oil pump 36 near the bottom housing 1 is connected to an oil outlet pipe 37. The outer side of the oil outlet pipe 37 is fixedly embedded inside the bottom housing 1. The outer side of the oil outlet pipe 37 is connected to a nozzle 38. The oil pump 36, which performs work in real time, will generate suction inside the oil suction pipe 30. The oil will enter the oil suction pipe 30 through the oil inlet 31 and, under the pressure of the oil pump 36, flow through the oil outlet pipe 37 and finally be sprayed out by the nozzle 38, thus lubricating the inner wall of the cylinder 3.

[0042] Working principle: When the engine is running, the combustion of fuel causes the power piston 8 to move up and down on the inner wall of the cylinder 3. As the piston 8 moves, it drives one end of the main connecting rod 6 via the shaft block 7. The other end of the main connecting rod 6 drives the rod sleeve 5, causing the power output rod 4 to rotate inside the bottom shell 1 and top shell 2, thus outputting power. Simultaneously, the driving bevel gear 9, which rotates with the power output rod 4, drives the inner hexagonal sleeve 11 to rotate at the bottom of the protective shell 12 under the meshing action of the driven bevel gear 10, and in turn drives the internal hexagonal block 13 to rotate. The main rod 14, which rotates with the hexagonal block 13, will rotate inside the stabilizing sleeve 15. The centrifugal rod 16 and centrifugal ball 17, which also rotate with the main rod 14, will, under the action of centrifugal force, cause the centrifugal ball 17 to spread outwards. The end of the centrifugal rod 16 away from the centrifugal ball 17 will drive one end of the second connecting rod 18. The other end of the second connecting rod 18 will pull the moving sleeve 20 through the shaft plate 19, causing the moving sleeve 20 and the force-bearing sleeve 21 to move longitudinally along the axis of the main rod 14. The design of its double-fork rod 25 allows the double-fork rod 25 to move within the force-bearing sleeve 21. A certain radial displacement prevents the double fork 25 from disengaging from the force-bearing sleeve 21 due to angular deviations in the relative movement direction. Therefore, when the force-bearing sleeve 21 moves and rotates, it drives the internal double fork 25, causing the rocker arm 24 to swing about the shaft 23 within the fixed rod 22. The slot 26 at the other end of the rocker arm 24 drives the connecting rod 35. The slot 26 is larger than the outer surface of the connecting rod 35, allowing for a certain radial displacement within, preventing interference between the two circumferential movements, thus driving... The crank 34, the extension rod 32, and the oil valve plate 33 swing in the direction of the axis of the extension rod 32, changing the inner diameter of the oil suction pipe 30 and the oil suction volume of the oil pump 36. Then, the oil pump 36, which is working in real time, will generate suction inside the oil suction pipe 30. The oil will enter the oil suction pipe 30 through the oil inlet 31 and, under the pressure of the oil pump 36, flow through the oil outlet pipe 37 and finally be sprayed out by the nozzle 38, lubricating the inner wall of the cylinder 3. The oil inside the oil reservoir 27 can be drained through the drain pipe 28 by rotating the pipe cover 29.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
