Working Principle

The tensioner is a commonly used holding device in the belt and chain transmission system. Its characteristic is to keep the belt and chain with proper tension during the transmission process, so as to prevent the belt from slipping, or to avoid the synchronous belt from jumping and falling off teeth. drag out. Or prevent the chain from loosening and falling off, and reduce the wear of the sprocket and chain.

Features

In terms of effect, the tensioner using the spring structure is simple in construction and cheap, so it is more commonly used, while the tensioner using rubber parts has a longer life than the spring due to the good elastic properties of rubber, but it has a long lifespan. The performance requirements are relatively high and the price is relatively expensive, so the usage is less, and it is usually used in high-end mechanical equipment.
