Does the generator idler need replacing?
When replacing the generator belt, it is usually necessary to replace both the tension wheel and the idler wheel. This is because the tension wheel and idler wheel are closely related to the generator belt, their life is similar, and replacement can avoid possible problems in the future to ensure the normal operation and safety of the vehicle. If these parts are not replaced, it may cause problems with the belt during use, affecting the performance and safety of the vehicle. In addition, considering the replacement cycle and maintenance cost of these parts, it is more scientific to replace these parts in sets, so as to ensure that they work better with the new parts of the belt.
Idler is a mechanical term that refers to a gear that plays a transfer role in the middle of two transmission gears that are not in contact with each other, and engages with these two gears at the same time to change the direction of rotation of the passive gear so that it is the same as the driving gear. The role of the idler is mainly to change the steering, and can not change the transmission ratio.
Generator idler and pulley are not the same part.
The generator idler and pulley play different roles in the mechanical system. Idler wheel, also known as tension wheel, plays a role in the drive system to adjust the belt direction, avoid belt shaking and prevent the belt from slipping. It protects the engine and other mechanical parts from damage by changing the contact area between the belt and the pulley, improving the friction force and ensuring the stable operation of the belt. The pulley is the part directly involved in power transmission, which works with the idler to ensure the efficiency and stability of the entire transmission system.
When replacing the generator belt, it is usually recommended to replace the tension wheel and idler wheel at the same time, as these components have a similar life span and a simultaneous replacement ensures vehicle performance and safety . In addition, the idler is located in the middle of the two transmission gears that do not contact each other, which plays a role in changing the direction of rotation of the passive gear, and helps to connect the distant shaft, which is helpful to the stability of the system .
To sum up, although the generator idler and pulley are both important components in the drive system, their functions and positions are different, so they are not the same part.
What is the cause of the abnormal noise of the engine idler?
The cause of the abnormal noise of the engine idler may be caused by the damage of the idler or the failure of the internal bearing ball. An engine is a machine that can convert various forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. In the automobile engine, the working principle of the two-stroke engine and the four-stroke engine is different, and the vast majority of the automobile engine is four-stroke. The working cycle of a four-stroke gasoline engine consists of four piston strokes, namely, intake stroke, compression stroke, work stroke and exhaust stroke. If the engine is found to have abnormal idler sound, it is recommended to check and repair in time to ensure the normal operation of the car.
