Product Description
Automobile tensioner is an important part of the engine timing system, which is used to keep the tension of the timing belt or chain and ensure the synchronous operation of all parts of the engine. The material selection of tensioner plays a key role in its service life and performance. Common tensioner materials include:
1. Metal tensioning wheel: Metal tensioning wheel is usually made of metal materials such as aluminum alloy, steel or cast iron, which has high strength and hardness, can withstand large tension and friction and wear under high-speed rotation, and has long service life and stable working performance.
2. Plastic tensioner: Plastic tensioner is usually made of high-strength engineering plastics, such as nylon, polyamide, etc. It has a light weight and a low friction coefficient, which can reduce the wear of timing belt or chain and reduce noise and vibration at the same time, but its service life may be shorter than that of metal tensioner.
3. Synthetic material tensioner: Synthetic material tensioner is usually made of elastic materials such as polyurethane and rubber, which has good cushioning and shock absorption effects, can reduce the noise and vibration when the engine is running, and at the same time reduce the wear of timing belt or chain, but compared with metal tensioner, its strength and wear resistance may be poor.
When selecting the material of the tensioner, it is necessary to consider the working environment, service conditions and expected performance requirements of the engine to ensure that the tensioner can work stably and reliably, and can cooperate well with the timing belt or chain to ensure the normal operation of the timing system of the engine. Therefore, the material selection of tensioner is very important.
