ABSTRACT:
An adjustable self-aligning tensioner, for a drive belt, the belt tensioner being self-aligning and readily adjustable. Such belt tensioner includes a pair of idler pulleys and a support for the pair of idler pulleys. A mount rotatably carries the idler pulley support. The mount is adjustably positioned relative to the drive belt, whereby the support carried by the mount locates the idler pulleys so as to be respectively engageable with the drive belt on opposite sides thereof. A mechanism reactive with the support and the mount urges the idler pulleys into engagement with the drive belt with a force so as to provide an adjustable preselected tension on the drive belt.
