According to the tensioner accessories supplier , the tensioner accessories are divided into accessory tensioner (generator belt tensioner, air conditioner belt tensioner, supercharger belt tensioner, etc.) and timing belt tensioner. The tensioning wheel is mainly divided into mechanical automatic tensioning wheel and hydraulic automatic tensioning wheel according to the tensioning method. The tensioning wheel is mainly composed of a fixed housing, a tensioning arm, a wheel body, a torsion spring, a rolling bearing and a spring sleeve. The tension can be adjusted automatically according to the degree of belt tightness, so that the transmission system is stable, safe and reliable. The tightening ring is a vulnerable part such as auto parts. The belt is easy to wear after a long time. The belt runs more smoothly, makes less noise, and prevents slipping.

The tensioning wheel is a routine maintenance project. Generally, the tensioning wheel accessories need to be replaced after 60,000 to 80,000 kilometers. Usually, if there is abnormal noise at the front of the engine or the position of the tensioning wheel’s tensioning mark deviates too much from the center, it means the tension force insufficient. It is recommended to replace the generator belt, tensioner pulley, support pulley, and single pulley at 60,000-80,000 kilometers (or when the front-end accessory system has abnormal noises). The function of the tensioner is to adjust the tightness of the belt, reduce the vibration of the belt to a certain extent, prevent the belt from slipping, and ensure the normal and stable operation of the transmission system.

Tensioner accessories suppliers said that the tensioner accessories are generally replaced with belts, support rollers and other accessories to avoid worries. In the actual use of the tensioner, in order to maintain proper belt tension, avoid belt slippage, and compensate for elongation caused by belt wear and aging, a certain torque is required. While the belt tensioner is running, the moving belt can cause vibrations in the tensioner, causing premature belt and tensioner wear. For this purpose, a resistance mechanism is added to the tensioner. However, there are many parameters that affect the torque and resistance of the tightening wheel, and the influence of each parameter is not the same. Therefore, the relationship between the components of the tightening wheel and the torque and resistance is very complicated. The change of torque directly affects the change of resistance, which is the main factor affecting resistance, and the main factor of torque is the parameter of torsion spring. Appropriately reducing the middle diameter of the torsion spring can increase the resistance value of the tensioning wheel. The tensioning pulley is a belt drive tensioning device. When the center distance of the belt cannot be adjusted, the belt can be tensioned with a tensioning pulley. The tensioner is a driving wheel that is pressed on the belt to change the winding angle of the pulley or control the tension of the belt. It is a belt-driven tensioning device; the tensioner is a commonly used holding device in belt and chain transmission systems. Its characteristics It is to keep the belt and chain with proper tension during the transmission process, so as to avoid the belt slipping, or to avoid the synchronous belt from jumping and pulling out of the teeth; a car generally has 1 to 2 tensioning wheels, the same size , mainly plays the role of tightening the belt. There is no difference between the timing tensioner and the normal tensioner, and its working principle is different.

According to the supplier of the tensioning pulley accessories, the tensioning pulley fittings are generally installed on the inner side of the loose side, so that the belt can only bend in one direction; at the same time, in order to ensure that the winding angle of the small pulley does not decrease too much, the tensioning pulley should be installed as close as possible to the large belt. wheel.

Function: The tensioning wheel accessory is a belt drive tensioning device. When the center distance of the belt cannot be adjusted, the tensioning wheel can be used to tighten the belt.

Composition: Timing tensioner is mainly composed of fixed housing, tensioning arm, wheel body, torsion spring, rolling bearing, spring sleeve and so on. The tension can be adjusted automatically according to the degree of belt tightness, so that the transmission system is stable, safe and reliable.
