Tensioner pulley.
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.
When the tightening wheel rings in the car, an effective solution is to apply lubricating oil between the tensioning wheel and the fixed point.
This significantly reduces noise issues and makes your driving quieter and more comfortable.
The tension wheel, used in the automotive drivetrain, is a key component that keeps the belt properly tensioned. According to different applications, the tensioner is divided into accessory tensioner and timing belt tensioner, which are respectively responsible for the tensioner of the generator belt, air conditioning belt, booster belt and other accessories as well as the engine timing belt. The tension wheel is divided into mechanical and hydraulic automatic tension wheel to meet different tension needs.
In particular, the timing belt plays a crucial role in the engine valve system. It is closely connected to the crankshaft and ensures accurate intake and exhaust times through precise transmission ratios. Therefore, maintaining the good condition and tension of the timing belt is crucial to the normal operation of the engine.
In the event of the problem of tightening wheel ringing, in addition to applying lubricating oil, it is recommended that the owner check and replace the belt and tension wheel with serious wear in time. This can effectively avoid more serious failures and ensure the safety and reliability of the car.
The generator tension wheel can be replaced with a smaller wheel.
The replacement of the generator tension wheel is usually to solve the problems that occur in the operation of the vehicle, such as the electric vehicle riding jitter caused by the bearing damage, or the performance decline caused by the problem of the tension wheel itself. When replacing the tensioning wheel, it has been experimentally proved that the tensioning wheel can be replaced separately without replacing the entire assembly, which can save costs. When installing, it should be noted that the screws are relatively tight, and it may be necessary to use tools such as wind cannons, and apply some rot-resistant glue on the screws to help fix them. In addition, although in some cases it is feasible to replace the tension wheel individually, it is also recommended that it is better to replace the complete set, because it can be more convenient. However, some users have successfully purchased and replaced the tension wheel separately, and the use effect is good.
In general, whether to turn a large wheel into a small wheel depends on a number of factors, including the specific model of the vehicle, the design requirements of the tension wheel, and the individual's repair experience and needs. Before making any replacement, it is recommended to read the vehicle's owner's manual in detail or consult a professional automotive repairman to ensure safety and effectiveness .
