• Specification

• Function

1.Preventing Belt Slippage: During the operation of the equipment, the belt may stretch due to factors such as long - term use and high - load operation. The belt tensioner can automatically adjust the belt tension to keep the belt in a properly tight state. This prevents the belt from slipping on the pulley, ensuring that the power can be effectively transmitted from the driving pulley to the driven pulley, and the relevant components can work properly.

2.Avoiding Tooth Skipping and Tooth Loss of Synchronous Belts: For equipment using synchronous belts, if the belt tension is insufficient, it is easy to cause tooth skipping or tooth loss of the synchronous belt, which will lead to the disorder of the power transmission sequence and affect the normal operation of the equipment. The belt tensioner can ensure that the synchronous belt is always in the best tension state, reducing the risk of such failures.
