Tensioning devices are essential to the mechanical power transmission systems to make belts and chains work effectively and dependably. Without the correct tension, drive belts and chains may fall, vibrate, or be worn out prematurely - resulting in lowered performance and increased maintenance expenses. Whether you are finding mechanical solutions to industrial equipment or maintenance needs, the knowledge of the various types of tensioning devices would enable you to choose the appropriate system to suit your needs. 1. Mechanical Tensioning Devices The easiest form of tensioning devices is mechanical tensioners. They must be manually adjusted by tightening bolts or screws to achieve the right tension level. They tend to be used in a system where there is minimal wear on belts or chains, and they can be checked up regularly. Their simple construction makes them cheap and can be fitted in smaller installations where automatic adjustment is not a big factor. 2. Spring‑Loaded Tensi...
