Tensioner pulley.
The tensioner is divided into accessory tensioner (generator belt tensioner, air conditioning belt tensioner, mechanical supercharger belt tensioner, etc.) and timing belt tensioner according to the location.
The tightening wheel can be divided into mechanical automatic tightening wheel and hydraulic automatic tightening wheel according to the tightening way.
The tightening wheel is mainly composed of a fixed shell, tension arm, wheel body, torsion spring, rolling bearing and spring sleeve, etc., which can automatically adjust the tension force according to the different tightness of the belt, so that the transmission system is stable, safe and reliable.
The tightening wheel is a wearing part of automobile and other spare parts, the belt is easy to wear for a long time, the belt groove will be stretched after grinding deep and narrow, the tightening wheel can be automatically adjusted according to the wear degree of the belt through the hydraulic unit or damping spring, in addition, the tightening wheel belt runs more smoothly, less noise, and can prevent slipping.
The tension wheel belongs to the routine maintenance project, generally 6-80,000 kilometers need to be replaced, usually if the engine front end has abnormal howling or the tension wheel tension mark location deviation center too much, on behalf of the tension force is insufficient. It is recommended to replace the belt, tensioning wheel, idler wheel, and generator single wheel when the front end accessory system is abnormal at 60,000-80,000 km.
The function of the tightening wheel is to adjust the tightness of the belt, reduce the vibration of the belt during operation and prevent the belt from slipping to a certain extent, so as to ensure the normal and stable operation of the transmission system. Generally, it is replaced with collaborative accessories such as belts and idlers to avoid worries.
In order to maintain proper belt tightening force, avoid belt slip and compensate the elongation caused by belt wear and aging, a certain torque is required in the actual use of the tightening wheel. When the belt tension wheel is running, the moving belt may cause vibration in the belt tension wheel, which can cause premature wear of the belt and tension wheel. To this end, a resistance mechanism is added to the tightening wheel. However, because there are many parameters affecting the torque and resistance of the tightening wheel, the influence of each parameter is not the same, so the relationship between the parts of the tightening wheel and the torque and resistance is very complicated. The change of torque directly affects the change of resistance, and is the main influencing factor of resistance, and the main influencing factor of torque is the parameter of torsion spring. Properly reducing the middle diameter of the torsion spring can increase the resistance value of the tension wheel.
Does the generator tightening wheel sound abnormally and need to be replaced
Requires
Generator tension wheel abnormal sound really need to be replaced. This is because the abnormal sound of the tension wheel is usually caused by aging or damage to the internal bearing, which may cause further damage to the car and affect its normal driving and performance. Here are a few key points:
The main function of the tightening wheel is to adjust the tightness of the belt to ensure the stability and safety of the transmission system. Abnormal noise may mean damage to bearings or other internal components, which will affect the normal function of the tension wheel.
If the abnormal sound is not dealt with in time, it may lead to more serious problems, such as timing skip, ignition and valve timing disorders, which will affect the performance and safety of the engine.
Replacing the tension wheel is a direct way to solve the abnormal sound problem, and it is recommended to replace the belt and idler accessories to ensure the overall performance and stability of the system.
In short, in order to ensure driving safety and the stability of vehicle performance, once the tension wheel is found to have an abnormal sound, it should be inspected immediately and the damaged parts should be replaced.
How long to replace the generator tightening wheel
The replacement cycle of the generator tightening wheel is usually recommended after about 2 years of driving or a total of 60,000 km. This recommendation is based on the tensioning wheel as a key belt tensioning device in the automotive transmission system, which can automatically adjust the tensioning force according to the change of belt tightness, so as to ensure the stability, safety and reliability of the transmission system. The tensioning wheel consists of a fixed housing, tensioning arm, wheel body, torsion spring, rolling bearing and spring bushing and other components. The life of these components is significantly affected by vehicle use conditions and environmental factors, so the recommended inspection and replacement cycle is about 3 years or 60,000 kilometers. In addition, if the tightening wheel fails, it should also be replaced in time to ensure the normal operation of the car.
