Description

Technical Field

[0001] The utility model relates to the technical field of engines, in particular to a gear chamber of a diesel engine with large torque and low energy consumption. Background Art

[0002] The gear chamber of a diesel engine is a key component in the engine. It plays an important role in transmitting and adjusting the speed and torque between various parts of the engine. The gear chamber is usually located at the front or rear of the diesel engine, and contains multiple gears and related mechanical parts. These gears are connected to the crankshaft through a transmission shaft, and the rotation of the crankshaft is transmitted to other parts, such as the camshaft and the oil pump, through the cooperation of the gears. The gears in the gear chamber adjust the speed and torque of different parts through different ratios to achieve the normal operation of the engine. In order to ensure the smoothness and reliability of the transmission, the gear chamber of a diesel engine is usually composed of precision-machined gears and bearings. The gears need to be precisely machined and matched to ensure the accuracy and reliability of the transmission. The bearings play an important role in supporting and protecting the gears. They can reduce the friction and wear of the gears in motion and help the gears maintain a stable working state. During operation, the gear chamber needs to be lubricated and cooled to reduce the generation of friction and heat. The lubricating oil is sent into the gear chamber through the lubrication system to lubricate the gears and bearings and reduce the friction and wear between them. The cooling system removes the heat through circulating coolant, ensuring that the temperature of the gear chamber is within the normal range and avoiding damage to the gears and related components due to overheating. The gear chamber also needs regular maintenance and inspection to ensure the normal operation of the gears and related components. Regularly replace the lubricating oil and coolant, clean the debris and dirt in the gear chamber, check the wear of the gears and bearings, and repair and replace them in time. This can extend the service life of the gears and related components and ensure the normal operation of the engine. The gear chamber of the diesel engine plays a vital role in the operation of the engine. It ensures the normal operation of the engine by transmitting and adjusting the speed and torque between the various parts of the engine. The gears and bearings in the gear chamber are precision machined, and the operation of the lubrication and cooling systems, as well as regular maintenance and inspection, are the key to ensuring the normal operation of the gear chamber.

[0003] However, the conventional gear chamber has poor sealing and has some problems. First, due to insufficient air tightness, the gear chamber is prone to noise leakage under high torque working conditions. This will not only bring noise pollution to the working environment, but also affect the normal operation of the equipment. Secondly, insufficient sealing will also cause lubricating oil to leak from the gear chamber. Lubricating oil plays an important role in gear transmission. It can reduce friction and wear between gears and ensure the normal operation of transmission. However, due to poor sealing, lubricating oil will continue to leak out of the gear chamber, resulting in increased lubricating oil consumption and the need for frequent replenishment. This not only increases the maintenance cost of the equipment, but also causes the gear chamber to fail to form a sufficient lubricating film, reducing the efficiency of the gear transmission. At the same time, the sealing will also cause foreign matter such as dust and impurities to enter the gear chamber, further aggravating the wear and damage of the gears. These impurities will mix with the lubricating oil to form abrasive particles, further aggravating the wear of the gears and shortening the service life of the equipment. Utility Model Content

[0014] 1. The gear chamber of the high-torque and low-energy diesel engine uses a convex structure, a concave structure, and a sealing belt structure. Compared with the traditional technical structure, the gear chamber uses a wider sealing belt than the original product, and forms a tight connection through the convex structure protruding from the side panel and the concave structure of the shell, thereby improving the sealing performance of the gear chamber.

[0022] 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 in 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.

[0023] See also Figure 1 , Figure 2 , Figure 3 The gear chamber of a high-torque, low-energy diesel engine comprises a housing 1 and a side plate 2. The side plates 2 are fixedly mounted on both sides of the housing 1. An air pump module 3 is also fixedly mounted on the top of the housing 1. The air pump module 3 is connected to the inside of the housing 1. The role of the air pump module 3 in the gear chamber of a high-torque, low-energy diesel engine is to inflate the inside of the gear chamber, thereby forming a high-pressure environment. A high-pressure environment helps to form a stronger lubricating film. A uniform and stable lubricating film is formed between the gears and other moving parts, reducing friction and wear, and improving the efficiency and life of the gear transmission. In addition, the formation of a lubricating film can effectively reduce the friction between the gears and other moving parts, reduce friction losses, and thus improve energy utilization efficiency. Reducing friction losses can also reduce heat generation, reduce the temperature rise of the gear chamber, and enable better lubrication and cooling of the inside of the gear chamber, thereby reducing energy consumption and improving the energy efficiency of the diesel engine. A pressure relief valve 7 is also fixedly installed on the housing 1. The pressure relief valve 7 is connected to the inside of the housing 1. The function of the pressure relief valve 7 in the gear chamber of a high-torque, low-energy diesel engine is to adjust the pressure inside the gear chamber and ensure that the pressure is within a safe range. When the pressure inside the gear chamber exceeds the set safety pressure, the pressure relief valve 7 will open to discharge excess gas, thereby keeping the pressure inside the gear chamber within a safe range. If there is no pressure relief valve, excessive pressure may cause the seal inside the gear chamber to fail, or even damage the gear chamber and related components. By setting a suitable safety pressure value, the pressure relief valve can maintain a certain pressure range inside the gear chamber to avoid the impact of excessive or low pressure on the gears and lubricating film. Maintaining a stable pressure inside the gear chamber helps to ensure the formation and maintenance of the lubricating film and improve the efficiency and life of the gear transmission. Please refer to Figure 4 and Figure 5, a convex structure 4 is provided at the joint position between the side plate 2 and the housing 1, a sealing tape 5 is wrapped on the convex structure 4, a concave structure 6 matching the convex structure 4 is provided on the side plate 2, and the convex structure 4 and the concave structure 6 are fixedly connected. The function of the convex structure 4 and the concave structure 6 is to form a sealed connection to ensure the sealing performance of the gear chamber and prevent leakage. The sealing tape 5 wrapped on the convex structure 4 cooperates with the concave structure 6 on the side plate 2 to form a tight connection, thereby ensuring the sealing performance of the gear chamber. This sealed connection can prevent the leakage of gas and liquid, and maintain the high pressure environment and lubricating film inside the gear chamber. And the sealed connection between the convex structure 4 and the concave structure 6 can not only prevent the leakage of gas and liquid, but also prevent external impurities from entering the gear chamber. This is very important for keeping the interior of the gear chamber clean and operating normally. The fixed connection between the convex structure 4 and the concave structure 6 can also enhance the stability of the side plate 2 and the housing 1. Under high pressure environment, the fixed connection can effectively prevent the loosening or falling off between the side plate 2 and the housing 1, ensuring the structural stability of the entire gear chamber.

[0024] See also Figure 1 , an axial hole 18 is provided on the side plate 2, and a sealing ring 19 with a diameter smaller than the diameter of the axial hole 18 is provided on the axial hole 18; an axial hole 2 10 is provided on the housing 1, and a sealing ring 2 11 with a diameter smaller than the diameter of the axial hole 2 10 is provided on the axial hole 2 10. The function of the sealing ring 19 and the sealing ring 2 11 is to achieve sealing at the position where the axial hole 18 and the axial hole 2 10 are connected to the side plate 2 to prevent leakage of gas or liquid. When the shaft is connected to the axial hole, the sealing ring will be squeezed and fill the gap between the axial hole and the shaft, thereby forming a sealed interface to prevent gas or liquid from leaking out of the axial hole, maintaining the high-pressure environment of the gear chamber and the stability of the lubricating film. The sealing ring 19 and the sealing ring 2 11 are made of elastic material and have certain elasticity and plasticity. When the shaft is connected to the axial hole, the sealing ring can adapt to different gaps and surface unevenness, maintain good sealing performance, and prevent leakage. Please refer to Figure 4 , an air cavity 12 is also provided inside the side plate 2, and the gas pressure in the air cavity 12 is negative pressure. The design of the negative pressure air cavity 12 can produce a waveguide effect, so that a part of the sound waves propagate therein, thereby reducing the effect of noise propagating to the outside. A second pressure relief valve 13 is also fixedly provided on the side end surface of the side plate 2, and the second pressure relief valve 13 is connected to the air cavity 12. The side plate 2 is fixedly connected to the housing 1 by bolts.

[0025] Working principle: When the gear chamber is used, a seal will be formed between the convex structure 4, the concave structure 6, and the sealing belt 5 structure, and the sealing ring 19 and the sealing ring 2 11 set on the shaft hole 1 8 and the shaft hole 2 10 will also form a sealing relationship between the shaft connected to the gear chamber and the shaft hole 1 8 and the shaft hole 2 10, so that a sealed environment is formed in the gear chamber. When the gear chamber is working, the air pump module 3 will inflate the interior of the gear chamber to form a high-pressure environment inside. The high-pressure environment helps to form a stronger lubricating film, thereby reducing the friction between the gears and other moving parts. Reducing friction loss can improve the efficiency of gear transmission, thereby reducing the energy consumption of the gear chamber. And in this sealed environment, combined with the air cavity 12 structure in the side plate 2, the design of the negative pressure air cavity 12 can produce a waveguide effect, so that a part of the sound waves propagate therein, thereby reducing the effect of noise propagation to the outside.
