Basic Information Of Belt Tensioner

The tensioner is a commonly used holding device on the belt and chain transmission system. Its characteristic is to maintain the belt and chain can have appropriate tension during the transmission process, so as to avoid slipping of the belt, or to avoid tooth jumping and tooth loss of the synchronous belt. Drag out.

Or it can prevent the chain from loosening and falling off, and reduce the wear of the sprocket and chain. The structure of the tensioner is various, which generally includes a fixed structure and an elastic automatic adjustment structure. The fixed structure mostly uses a fixed adjustable sprocket to adjust the tension of the belt and sprocket. The elastic automatic adjustment structure mostly uses elastic components. Automatic rebound controls the tensioning of belts and chains. The self-adjusting chain tensioners in China mostly adopt spring structure, while foreign tensioners mostly adopt rubber parts.

From the effect point of view, the tensioner with spring structure is simple and cheap to construct, so it is more commonly used, while the tensioner with rubber parts has a longer life span than the spring due to the good elastic properties of rubber, but its The performance requirements are relatively high, and the price is relatively expensive, so the usage is less, and it is usually applied to high-end mechanical equipment.
