ABSTRACT:
A belt drive arrangement has a drive belt 14 which passes around and transfers rotation between a plurality of ratable members (pulleys) 16, 26, 20, 22, 24. The drive belt path includes both a belt tensioner 18 and an idler pulley 22. The idler pulley has a rotation axis and is mounted to a fixed structure on a mounting axis 36 which is eccentric to the rotation axis. The idler pulley is provided with a lever 40 by which it can be rotated about the mounting axis to vary the position of the surface of the idler pulley which is in contact with the belt relative to the mounting axis, and thus to vary the tension in the belt.
