Beijing Hyundai Langdong generator belt makes abnormal noise, why does it still make noise after rep

Hello, the problem you mentioned is normal. When it gets cold in winter, the generator belt becomes hard. Starting in the morning will reduce battery voltage, so the generator has a heavy load and the belt will slip easily. When the generator is turned off, power consumption is reduced and power output is reduced. Therefore, the sound of the belt sliding disappears, so you can't tell anything at all. However, you also need to tighten the generator belt. hope this can help you

What are the different types of belts used in automobile engines? What should you pay attention to when purchasing?

The noise of the belt is a squealing and harsh sound. If there is such a noise, please check the degree of aging of the belt and its tightness. As long as there is no aging and tightening, there will be no problem. Generally, if theouter belt is replaced, it will need to be adjusted a second time as it will stretch to a certain extent after being used for a certain period of time. time.

Abnormal noise from the belt usually occurs when the car is cold, especially when the car is refueling when the car is cold, but it is caused by the external belt. I don't know what model you have, but usually external belts include generator belts and compressor belts.

It is best to go to the car dealership to check. You can't adjust it well if you don't have the tools.

What to do if the car belt slips

Engine timing belt, engine balance shaft belt, generator, water pump belt, air conditioning belt , power pump belt. Generally speaking, the timing belt is the pmore important. If the timing belt is broken, the engine will not start, and in severe cases, the cylinder head and cylinder will be damaged. Usually replaced every 60,000 kilometers. The new rubber belt is widely used in car engine drive systems due to its low noise, smooth operation and strong adaptability. There are two main types of transmission belts currently used in automobile engines: one is timing belt - mainly used in timing drive system; the other is accessory belt (including Micro-V belt and V-belt) - mainly used in accessories; Driving system.

As modern automobiles have increasingly higher requirements for environmental protection, comfort and other performance, the entire structure of theengine is compact and the transmission gear train of the front accessories of the engine becomes more and more complex. The working condition of the gear train directly affects the reliability of the entire vehicle, especially the timing belt, which is responsible for the synchronous transmission of the engine's valve timing. If the timing belt is abnormal and the timing is out of sync, the valve and piston can collide and cause catastrophic engine damage.

Rubber is an important component of transmission belts and the aging process of rubber products is still ongoing. In normal working environment, the transmission belt can reach ideal service life, but in actual use and maintenance, we are likely to affect the service life of the transmission belt due to Mishandling.

1. Ambient Temperature Factors:

For modern engines, compact engine compartments, high compression ratios, turbocharging on some models, etc. will all increase. The temperature inside the engine compartment makes the working environment of the drive belt quite harsh. Experiments show that the service life of the transmission belt decreases sharply as the ambient temperature increases. When you ignore the water temperature gauge on a hot summer day, not only does it damage your engine, but it also speeds up the life of your drive belt.

2. Factors related to lubricating oil:

Similarly, lubricating grease will also accelerate the aging process of rubber. Therefore, when removing and installing the drive belt, if your hands are stained with grease, please wipe them dry before continuing!Remember to never put the drive belt in oil! ! ! If your drive belt is accidentally stained with oil, please use it with caution and it is best to replace it immediately.

3. Installation tension:

For accessory belts, they use friction between the two sides of the belt and the pulleys to achieve transmission. Therefore, the installation tension will directly affect the operating conditions of the drive belt: if the tension is too low, the belt will slip. Slipping will not only increase wear on both sides of the belt, but also buildup. the heat generated by sliding will also accelerate the aging process of the belt; if the installation tension is too high, the belt may delaminate and lose its ability to operate.

Please pay attention to installation in strict accordance withith the installation voltage requirements specified by the manufacturer!

Please check and adjust the belt tension regularly to keep the tension within the specified range!

4. Transmission system factors:

The transmission belt has high demands on the transmission system. The coplanarity and coaxiality of components on the same transmission plane directly affect the utilization of the transmission belt. . life. In the entire transmission plan, only the transmission belt is a rubber part. Interference between the belt and this component caused by any component malfunction will seriously damage the drive belt. After prolonged operation of the transmission end face, the coplanarity or coaxiality of the original end face components is likely to be damaged due to wear and other reasons.

Please pay attention toregularly check the working condition of the end face components!

5. The impact of splashing foreign objects

Due to the complexity of car driving conditions, it is very likely that foreign objects will be splashed on the belt or pulley. the harsh external driving environment. In high-speed operation, it is like a knife constantly cutting the belt, which will quickly damage the transmission belt.

After driving in a harsh environment, please quickly check whether any foreign objects have been thrown into the transmission system!

6. Belt Bend

The cord is also an important part of the belt. It will cause the belt tension to ease under a small radius of curvature! Especially for ordinary belts: because its cords are made of fiberglass, fiberglass is relatively fragile, thistype of cord will cause significant attenuation of belt tension even under a small bend radius. It is therefore prohibited to bend the timing belt excessively!

If the belt is subject to a small bend radius, it should be wrapped on a round rod to prevent it from bending at an acute angle.

7. It is strictly prohibited to use tools to lift the drive belt when removing and installing the belt.

8. Recommendations for storage of transmission belts

During storage, the warehouse temperature should be maintained between -15 and 40°C and the relative humidity should be maintained between 50 and 50%. 80%.

During storage and transportation, should avoid direct sunlight or immersion in rain and snow, keep it clean, and avoid contact with acids, alkalis, oils, organic solvents and other substances which haveaffect the quality of the rubber. During storage, the belt should not be deformed due to excessive weight, to avoid mechanical damage, and should not be excessively bent or squeezed.

1. Turn off the engine and let it cool, open the engine hood and find the generator belt in front of the engine.

2. Press the belt between the pulleys to check its tension. If pressed more than 1/2 inch, a loose belt will affect generator performance and even damage the generator. belt.

3. Check the generator belt for oil or grease contamination. Turn the belt over to check for cracks in the inner layer, missing rubber parts, and slippage.

4. Loosen the generator adjustment bolt and adjust the pivot bolt.

5. Move the generator inward and loosen the belt. Strip the yardgenerator king from the pulley and remove the generator belt.

6. Compare the removed old belt with the new belt and install the new belt after confirmation.

7. Pull the generator out until the belt is taut and make sure the generator belt is installed in the correct position. Adjust the pivot bolt strictly according to the manufacturer's instructions.

8. Start the engine to check the results of the repair, and recheck the belt tightness after stopping the engine.
