Description

Technical Field

[0001] The utility model belongs to the technical field of gears, and in particular relates to an engine rust-proof gear. Background Art

[0002] Engine gears are key transmission components inside the engine, used to transmit power and torque and ensure the coordinated work of various engine components. They are usually made of high-strength metal materials, with precise tooth shapes and strict manufacturing process requirements to ensure efficient and smooth power transmission, thereby ensuring the normal operation of the engine.

[0003] The engine gears need to be added with oil when they are running so that the gears can work better. Generally, most gears use external oiling, which often cannot be added to the middle of the tooth angle of the gear meshing, resulting in low utilization rate of the oil by the gears and causing great waste.

[0004] The existing patent (application number: CN202023000028.5) is an engine gear that can be automatically refueled. At the same time, a blocking block is arranged inside the oil outlet. When the engine gear rotates at high speed, the blocking block will squeeze the telescopic spring under the action of centrifugal force, so that the blocking block will disengage from blocking the oil outlet. This is beneficial for timely refueling when the engine gear rotates at high speed, thereby reducing the friction between the engine gears and increasing the service life of the engine gears.

[0005] In view of the above problems, existing patents have provided solutions. However, in actual use, the high-speed rotation of the engine drives the blockage block to compress the spring to open the oil outlet to supply oil. There may be unstable oil supply at the oil outlet, which affects the lubrication effect of the gear. Improvements are needed. For this purpose, an engine rust-proof gear is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide an engine anti-rust gear which can automatically lubricate the contact surface during the operation of the gear, reduce wear, and form an oil film to enhance the anti-rust effect. The overall structure of the device is simple, the oil supply is stable, and the practicability is strong.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an engine rust-proof gear, comprising a wheel body and gear teeth evenly distributed on the wheel body, oil storage bins are arranged on both sides of the wheel body, evenly distributed and symmetrical through holes are opened on the surface of the wheel body, oil outlet pipes are arranged in the through holes, the oil outlet pipes are connected with the oil storage bins, valves are arranged in the oil outlet pipes, a pressure block is arranged in the oil outlet pipes, the pressure block is opposite to the middle of the valve, symmetrical limit paths are opened in the oil outlet pipes, limit blocks are slidably arranged on the limit paths, and the limit blocks and the pressure blocks are fixedly installed.

[0008] Preferably, two groups of valves are provided in the oil outlet pipe, and the two groups of valves are arranged between the outlet of the oil outlet pipe and the pressing block.

[0009] Preferably, a stop block is fixedly mounted on one side of the pressure block close to the valve, and the stop blocks are arranged in four groups which are evenly distributed.

[0010] Preferably, the size of the limiting block is matched with the size of the limiting track.

[0011] Preferably, the wheel body and the gear teeth are made of rust-resistant and corrosion-resistant alloy materials, and the surfaces of the wheel body and the gear teeth are provided with nano-level anti-rust coatings.

[0012] To sum up, compared with the prior art, the beneficial effects of the utility model are as follows: by setting the coordination between the wheel body, gear teeth, oil storage tank, through hole, oil outlet pipe, valve, pressure block, limit path, limit block and resistance block, the contact surface can be automatically lubricated during the operation of the gear to reduce wear, and at the same time a layer of oil film is formed to enhance the anti-rust effect. The overall structure of the device is simple, the oil supply is stable, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-6 , the utility model provides a technical solution:

[0023] An engine rust-proof gear comprises a wheel body 1 and gear teeth 2 evenly distributed on the wheel body 1, oil storage bins 3 are arranged on both sides of the wheel body 1, evenly distributed and symmetrical through holes 4 are opened on the surface of the wheel body 1, an oil outlet pipe 5 is arranged in the through hole 4, the oil outlet pipe 5 is connected with the oil storage bin 3, a valve 6 is arranged in the oil outlet pipe 5, a pressure block 7 is arranged in the oil outlet pipe 5, the pressure block 7 is opposite to the middle of the valve 6, a symmetrical limiting path 8 is opened in the oil outlet pipe 5, limiting blocks 9 are slidably arranged on the limiting path 8, and the limiting blocks 9 are fixedly installed with the pressure block 7.

[0024] When in use, the oil storage bin 3 is used to store lubricating oil, and the through hole 4 is used to place the oil outlet pipe 5. When the engine is running and drives the gears to mesh and rotate, the lubricating oil in the oil storage bins 3 on both sides of the wheel body 1 will enter the oil outlet pipe 5 connected to the oil storage bin 3 due to the action of centrifugal force. The valve 6 in the oil outlet pipe 5 is in a closed state under normal circumstances, which will prevent the lubricating oil from flowing out at will. However, when the pressure block 7 is subjected to the action of centrifugal force, it will move to the outside of the oil outlet pipe 5, thereby pressing the valve 6 to make it slightly open. The lubricating oil then flows out through the slightly opened valve 6, automatically lubricating the contact surface between the wheel body 1 and the gear tooth 2, which not only reduces the wear of the gear, but also forms a layer of oil film on the gear surface, further enhancing the anti-rust effect.

[0025] There are two groups of valves 6 in the oil outlet pipe 5, and the two groups of valves 6 are arranged between the pipe mouth of the oil outlet pipe 5 and the pressing block 7; there are two groups of valves 6 in the oil outlet pipe 5, which can block the lubricating oil from flowing out of the first layer of valves 6 through the second layer of valves 6. When there is enough lubricating oil between the first layer of valves 6 and the second layer of valves 6, the lubricating oil is pushed out from between the second layer of valves 6 by the action of pressure, so as to lubricate the wheel body 1 and the gear teeth 2, which helps to improve the utilization rate of the lubricating oil.

[0026] A stop block 10 is fixedly installed on the side of the pressure block 7 close to the valve 6, and the stop block 10 is provided with four evenly distributed groups; when the stop block 10 on the side of the pressure block 7 close to the valve 6 is subjected to a force, the four evenly distributed groups of stop blocks 10 can transfer the force to the valve 6 more evenly, so that the valve 6 opens more smoothly, thereby ensuring the stability of the oil supply.

[0027] The size of the limit block 9 is matched with the size of the limit path 8; since the size of the limit block 9 is matched with the size of the limit path 8, during the movement of the pressure block 7, the limit block 9 can slide stably in the limit path 8, ensuring the accuracy and reliability of the movement of the pressure block 7, thereby ensuring the stability of the oil supply process.

[0028] The wheel body 1 and the gear teeth 2 are made of rust-resistant and corrosion-resistant alloy materials, and the surfaces of the wheel body 1 and the gear teeth 2 are provided with nano-level rust-proof coatings; the wheel body 1 and the gear teeth 2 are made of rust-resistant and corrosion-resistant alloy materials, and nano-level rust-proof coatings are provided on their surfaces, which can effectively prevent rust and corrosion during the operation of the gears, thereby improving the service life and working performance of the gears.

[0029] Working principle:

[0030] When in use, the oil storage bin 3 is used to store lubricating oil, and the through hole 4 is used to place the oil outlet pipe 5. When the engine is running and drives the gears to mesh and rotate, the lubricating oil in the oil storage bins 3 on both sides of the wheel body 1 will enter the oil outlet pipe 5 connected to the oil storage bin 3 due to the action of centrifugal force. The valve 6 in the oil outlet pipe 5 is in a closed state under normal conditions, which will prevent the lubricating oil from flowing out at will. However, when the pressing block 7 is subjected to the centrifugal force, it will move to the outside of the oil outlet pipe 5, thereby pressing the valve 6 to make it slightly open, and the lubricating oil will then flow out through the slightly opened valve 6, automatically lubricating the contact surface between the wheel body 1 and the gear teeth 2, which not only reduces the wear of the gears, but also forms a layer of oil film on the gear surface, further enhancing the anti-rust effect;

[0031] There are two groups of valves 6 in the oil outlet pipe 5, which can block the lubricating oil from flowing out of the first layer of valves 6 through the second layer of valves 6. When there is enough lubricating oil between the first layer of valves 6 and the second layer of valves 6, the lubricating oil is pushed out from between the second layer of valves 6 by the action of pressure to lubricate the wheel body 1 and the gear 2, which helps to improve the utilization rate of the lubricating oil.

[0032] When the stopper 10 of the pressing block 7 close to the valve 6 is subjected to a force, the four groups of stoppers 10 evenly distributed can transmit the force to the valve 6 more evenly, so that the valve 6 opens more smoothly, ensuring the stability of the oil supply;

[0033] Since the size of the limit block 9 is adapted to the size of the limit path 8, the limit block 9 can stably slide in the limit path 8 during the movement of the pressure block 7, thereby ensuring the accuracy and reliability of the movement of the pressure block 7, and thus ensuring the stability of the oil supply process;

[0034] The wheel body 1 and the gear teeth 2 are made of rust-resistant and corrosion-resistant alloy materials, and a nano-level anti-rust coating is provided on the surface, which can effectively prevent rust and corrosion during the operation of the gear and improve the service life and working performance of the gear. The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and the utility model concept of the utility model, shall be covered by the protection scope of the utility model.
