Purpose
CHT tensioners stabilize belt/chain engagement by providing controlled preload and dynamic damping across temperature and load changes.
Key characteristics
- Spring/elastomer modules with defined stiffness to track elongation and shock.
- Pivoting and linear variants with selectable travel; sealed bearings on idler pulleys.
- Corrosion protection for wet/dusty environments; optional locking features for service.
Integration
- Place on slack span to maximize wrap angle; avoid resonance with span length.
- Size travel to expected elongation (thermal + wear) and set initial deflection accurately.
- Inspect pulley alignment and bearing temperature during early operation.
