How to properly maintain the crankshaft of the engine?

The function of the crankshaft of an engine is to withstand the force emanating from the crankshaft and convert it into a torque, which is derived from the crankshaft and pushes the rest of the accessories on the engine. It is the most important component in the engine. What are the methods of engine maintenance: regularly changing the engine oil and oil filter; Excellent maintenance of natural ventilation of the crankcase; Regularly clean the fuel system; Regularly clean the water storage tank and crankcase. An engine is a device that can convert other types of energy into chemical energy. It is suitable for driving force generation devices. According to its structure and function, it is divided into: an external combustion engine: fuel is ignited outside the engine; Gas turbine: fuel ignites in the internal structure of the engine; Gas turbine: Ignition causes high pressure natural gas, and the high pressure of natural gas is used to promote the rotation of the impeller of the gas turbine to derive driving force. Maintenance of gaps.

After cleaning the crankshaft, first check for cracks. Magnetic flaw detection equipment or dye penetrant can be selected for crack detection. If cracks are detected on the crankshaft, most of them should be damaged and replaced. Crankshaft bending repair. The bending deformation inspection shall be based on the common axis of the two main journals, and the axial cylindricity deviation of the middle main journal shall be inspected. During inspection, place the main journals on both sides of the crankshaft on the V-shaped block of the inspection plate, place the contact point of the micrometer vertically on the center main journal, and gradually rotate the crankshaft once. If the maximum shaking deviation indicated by the micrometer needle is the axial cylindricity error of the center main journal, a working pressure calibration should be performed. When it is less than this limit value, it can be calibrated according to the grinding main journal. The crankshaft is the most important component in an engine. It bears the force emanating from the crankshaft and converts it into a torque, which is derived from the crankshaft and pushes the rest of the engine accessories into operation.

The crankshaft is subjected to the combined effects of the centripetal force of the rotational mass, the periodically varying inertia moment of the steam body, and the reciprocating inertia moment, making the crankshaft withstand the action of bending and twisting loads. Therefore, it is specified that the crankshaft has sufficient compressive strength and bending stiffness, and the surface layer of the motor shaft should be resistant to wear, symmetrical in operation, and have good stability. To reduce the quality of the crankshaft and the centripetal force caused by its movement, the crankshaft motor shaft is usually made hollow. An oil inlet is provided on the surface of each motor shaft to facilitate the introduction or extraction of automotive oil for moistening the surface of the motor shaft. In order to reduce stress, the joint of the main journal, crank pin, and gear arm is connected by a connecting arc.

Regular maintenance: Only according to the regular maintenance of the car, can we avoid engine cylinder pulling and reduce damage to the large and small bearings. They are working normally, and the crankshaft is unlikely to cause problems! Choose high-quality lubricating grease: The selection of automotive oil is very important. Even if you have regular maintenance, if automotive oil cannot be selected correctly, the engine can easily be injured! Causes the engine to pull, causing severe crankshaft deformation! As far as possible, there is no need to drive the car violently, such as pressing the accelerator to the bottom, accelerating quickly, and other difficult problems! All of these will aggravate the increase in engine clearance! If conditions permit, regularly check the engine for any abnormal noise and increase in gap. For vehicles with more mileage, the increase in gap is normal, as long as it does not exceed the effective range, it can be used normally.
