What is a consequence of too little tension on a chain drive?

When there is too little tension on a chain drive, one significant consequence is that the chain may ride high on the sprocket. This phenomenon occurs due to insufficient grip between the chain links and the sprocket teeth. With inadequate tension, the chain doesn't maintain proper contact with the sprocket, causing it to rest higher than usual.

This lack of proper engagement can lead to inefficiencies in power transmission and increase wear on both the chain and sprocket. The possibility of the chain not properly aligning with the sprocket can contribute to further operational issues, such as misalignment and decreased overall system performance. Adequate tension is essential for maintaining optimal contact and ensuring smooth operation of the drive system.
