Description

Technical Field

[0001] The utility model relates to the field of diesel engines, in particular to a system device for supplying oil from a diesel engine to a coupling. Background Art

[0002] During the operation of a diesel engine, the performance and reliability of the coupling, as a key component connecting different power transmission parts, directly affect the operating efficiency and safety of the entire diesel engine. Especially in the application of high-power diesel engines, the lubrication of the coupling is particularly important under high-speed and high-load working environments. Traditional coupling lubrication methods often rely on an external oil supply system, which delivers lubricating oil to the inside of the coupling through oil pipes or oil channels to achieve lubrication effects. However, this method has problems such as unstable oil supply, easy leakage of lubricating oil, and difficult maintenance. These problems are more prominent, especially under high-temperature and high-pressure working environments.

[0003] Therefore, it is necessary to provide a new system device for supplying oil from a diesel engine to a coupling to solve the above technical problems. Utility Model Content

[0019] Compared with the related art, the system device for supplying oil from a diesel engine to a coupling provided by the utility model has the following beneficial effects:

[0020] 1. Through innovative design, this system supplies the lubricating oil inside the diesel engine directly into the coupling, ensuring that the lubricating oil can be stably and evenly supplied to all parts of the coupling that need lubrication. This direct oil supply method not only improves the lubrication effect, but also significantly improves the reliability and durability of the coupling, reducing the risk of failure and downtime caused by poor lubrication.

[0021] 2. As the system adopts the precise design of internal oil passage, the internal lubricating oil of diesel engine can be recycled, which reduces the dependence on external oil supply system. This means that system maintenance is simpler and more convenient, reducing maintenance cost and downtime. At the same time, as the utilization rate of lubricating oil is improved, the consumption of lubricating oil is also reduced, further reducing the operating cost.

[0022] 3. Equipped with purification components, through its internal filter element and magnet and other components, it can effectively remove impurities, iron filings and other pollutants in the lubricating oil, ensuring that the lubricating oil supplied to the coupling remains clean, which can not only improve the lubrication effect of the coupling, but also reduce the wear and failure caused by lubricating oil contamination. Clean lubricating oil reduces the wear and friction of equipment components, thereby extending the service life of couplings, crankshafts and other related components.

[0053] The working principle of the system device for supplying oil from a diesel engine to a coupling provided by the utility model is as follows:

[0054] During operation, the rotation of the crankshaft 2 drives the oil distribution flange 4 to rotate synchronously.

In this way, the lubricating oil can smoothly enter the lubrication cavity between the oil distribution flange 4 and the coupling 5 to play a lubricating role.

[0055] As the crankshaft 2 continues to rotate, when the oil passage 41 is at the top, the oil in the lubrication chamber of the coupling 5 will enter the oil passage of the coupling 5, and flow into the oil passage of the crankshaft 2 through the oil passage 41 of the oil distribution flange 4 to lubricate the crankshaft 2. After completing the lubrication task, the oil will flow back to the bottom shell 1, and flow back to the oil storage tank 3 through the leakage hole 12, thereby forming a lubricating oil cycle;

[0056] When the oil pump 7 extracts the lubricating oil in the oil storage tank 3, the lubricating oil will continuously enter the filter cartridge 62, where the magnet 66 will absorb and remove the iron filings carried in the lubricating oil, and the filter element 64 will filter the lubricating oil to remove impurities therein, ensuring that the lubricating oil entering the system always remains clean and efficient.
