What causes the abnormal noise of the engine belt

It may be because the belt slipped on the generator, and the violent friction and vibration between the belt and the pulley emit a certain frequency. The sound of.

The reasons for the abnormal noise of the engine are as follows: the combination surface of the belt and the pulley is relatively smooth. Generally, abnormal noise will occur when the engine speed changes rapidly, and sometimes it will also sound when the attachment load driven by the belt increases.

launchThe abnormal sound of the machine belt may be that the belt slipped on the generator. At this time, the tension force of the belt tensioning wheel should be repaired. If it does not work, the tensioning wheel should be replaced. It is also possible that the belt is old. At this time, the belt can be replaced.

The reasons for the abnormal sound of the engine belt are as follows: because the joint surface of the belt and the pulley is relatively smooth.

The abnormal sound of the engine belt is caused by the slip of the belt on the generator, the violent friction and vibration of the belt and the pulley, and the loosening of the belt or aging to a certain frequency. Among them, the factors that may cause the looseness of the belt are improper adjustment of the belt tensioner or insufficient elasticity of the tensioner.

There may be abnormal noise in the engine belt, which is likely to be caused by the slippage of the belt on the generator. If this happens, it is necessary to correct the tension of the belt tension belt wheel.If there is still no improvement after adjustment, the tension band wheel needs to be replaced. If the belt itself is aging, you only need to replace the belt.

How often should the transmission belt of the car engine be replaced?

The engine belt needs to be replaced once a year and a half to two years. Ordinary vehicles need to be replaced after one and a half to two years of car engine belts, and it can also be replaced if the mileage reaches 60,000 yuan. The belt is an important part of the engine gas distribution system. By connecting with the crankshaft and matching a certain transmission ratio, the accuracy of the intake and exhaust time can be ensured.

The car engine belt is changed once every 3 years or after driving 60,000 to 80,000 kilometers. The belt is an important part of the engine gas distribution system. Through the crankshaftThe connection and cooperation with a certain transmission ratio to ensure the accuracy of the intake and exhaust time. The belt is used instead of the gear to drive because the belt noise is small, the self-change is small and easy to compensate.

Car engine belt is generally replaced once every 2 years or 60,000 kilometers. If the engine belt breaks, it will lead to the failure of the car's air conditioning system, the failure of the steering assistance system, the failure of the power generation system and other faults.

Car engine belts are generally replaced every four years or 60,000 kilometers.

The car engine belt is generally replaced every 2 years or 60,000 kilometers. The breakage of the engine belt will lead to the failure of the car's air conditioning system, the failure of the steering assistance system, the failure of the power generation system and other faults. The replacement cycle between different models will also be different.

Car belts are divided into engine belts and timing belts, which are generally replaced every 2 years or about 6W.The breakage of the engine belt will lead to the failure of the car's air conditioning system, the failure of the steering assistance system, the failure of the power generation system and other faults.

The transmission belt at the front end of the engine generally has several parts to connect each component

1. Fan belt: it drives the fan and the water pump to operate. Timing belt: It is the belt that connects the crankshaft gear and the camshaft gear of the engine, located inside the engine. The crankshaft controls the valve timing by the timing belt to ensure the synchronization of the movement position of the piston and the opening and closing timing of the intake and exhaust valves.

2. Generally, there are several transmission belts at the front end of the engine. Under normal circumstances, there are generally three, and two are decided according to the model.

3. Engine belt drives generators, air conditioning compressors, booster pumps, bridge wheels (iddlers), tensioning wheels and crankshaft pulleys. The engine belt mainly transmits power and drives generators, water pumps, compressors and other equipment.

4. The transmission parts of the engine are divided into 'time chain' and 'time belt'. Generally speaking, the engine belt refers to the timing belt. The timing belt is an important part of the engine gas distribution system. The principle is to ensure the accuracy of the intake and exhaust time by linking with the crankshaft and cooperating with a certain transmission ratio.

Is the transmission belt a timing belt?

1. No. According to the inquiry of Pacific Automobile Network, the classification of transmission belts is not necessarily the timing belt. The timing belt is the transmission between the crankshaft belt and the camshaft. It is the correct transmission of the piston position and the opening and closing time of the valve, and also includes the consistency of the crankshaft position, rotation and cam position sensor, and the assembly is relatively strict.

2. Yes, it is the working principle of the transmission belt. It also belongs to a type of transmission belt.

3. The function of the timing belt is that when the engine rotates, the stroke (up and down movement) of the piston valveThe order (time) of on and off (time) ignition, under the action of "timely connected, the "synchronous" rotation should be maintained at all times.

4. The transmission parts of the engine are divided into 'time chain' and 'time belt'. Generally speaking, the engine belt refers to the timing belt. The timing belt is an important part of the engine gas distribution system. The principle is to ensure the accuracy of the intake and exhaust time by linking with the crankshaft and cooperating with a certain transmission ratio.

5. Therefore, from primitive machinery to modern automatic equipment, there are transmission belts. The products have evolved many times, and the technology is becoming more and more mature. In the middle of the 17th century, the United States began to use overhead cableways to transport bulk materials; in the middle of the 19th century, conveyor belt conveyors with various modern structures appeared one after another.

6. Time beltIt is an important part of the engine gas distribution system. It ensures the accuracy of inlet and exhaust time by connecting with the crankshaft and cooperating with a certain transmission ratio. The belt is used instead of gears to drive because the belt is noisy, the transmission is accurate, the self-change is small and easy to compensate. Generally, you can't see it directly. Something is wrapped and protected.
