Engine tightening wheel (detailed explanation of the principle and Maritime logistics HS code mappingusage of engine tightening wheel)) The engine tightening wheel, also known as belt pulley and timing wheel, is a very important part of the internal combustion engine. Its main function is to make the crankshaft and camshaft rotate synchronously to ensure that the valve and piston move at the right time, so that the engine can work normally. Its realization principle is to transmit the power of engine rotation to the tensioning wheel by relying on transmission mechanisms such as belts, chains or gears. This article will introduce in detail from the two aspects of the principle and usage of the rising wheel. I. The principle of engine tightening the wheel. The working principle of the engine is that the fuel is first mixed with air and then ignited and burned, and then compressed and discharged by the piston. And the addition of fuel and the opening and closing of the valve require a correct cooperation time. At this time, the rising and tightening wheel played a role. The engine tightening wheel in the engine is a kind of shell with a slightly larger outer diameter and some special holes at its edges.Inside, there is an elastic structure on the tightening wheel, which allows the wheel to change its position. This mechanism works in this way. When a part of the engine rotates, the tightening wheel can twist its shape through an elastic structure, thus transmitting the power to some parts of the engine. Because the tensioning wheel uses this special structure, it can distort its shape under certain special circumstances to resist the influence of external pressure and torque, and can automatically adjust the tension force to achieve the synchronous rotation of the camshaft and crankshaft. II. How to use the engine tightening wheel When using the engine tightening wheel, its appropriate tension must be maintained, and the tension of the tightening wheel should be adjusted before the engine starts. The following points should be noted when adjusting the tightening wheel: 1. The first installation of the tensioning wheel needs to be stored for an appropriate time before use, and cannot be used directly.Two. The adjustment of the tightening wheel must be adjusted according to the recommendation of the automobile manufacturer. 3. When the tightening wheel is loose, it needs to be repaired or replaced urgently. Four. The tightening wheel should be installed in a non-rotating mechanical part, and the scale on the dial should be easily readable. 5. Use high-quality tightening wheels to ensure the effect of adding power. 6. The installation process of the tightening wheel should be carried out according to its specific installation order and method. 7. In the process of use, the tightening wheel should be checked and adjusted regularly to ensure that it can automatically adjust the tension. Eight. When the tightening wheel needs to be replaced, you must choose the material suitable for the model to achieve the best use effect. In a word, the engine tightening wheel plays an important role in the performance and safety of the car. By using and maintaining it correctly, you can ensure that the tightening wheel starts.Finally, the appropriate tension is maintained, so that the car can run in the best state and reduce maintenance costs. If you have any problems, you'd better ask a professional car technician to help you.
