Multi-Disc Viscous Auto-Tensioner for Timing Belts 930623

This paper describes the construction, characteristics and capabilities of a compact automatic tensioner for timing belts that was recently developed by NSK.
This auto-tensioner differs from conventional ones having separate actuators. By incorporating the damping mechanism inside the bearing, a compact size nearly equal to that of fixed type tensioners was achieved. The damper is a multi-disc viscous type that uses high viscosity silicone oil.
