Abstract

A belt tensioner for an endless drive belt for vehicle accessories has a shaft which is mounted in a fixed position adjacent the belt. A lever is pivotally mounted on the shaft and has an idler pulley rotatably mounted on an extended end of the lever. The pulley is movable into tensioning engagement with the belt by rotation of the lever. A first cam plate is slidably mounted on the shaft and is engaged with a second cam plate which is attached to the lever for rotation with the lever. The cam plates each have a plurality of a series of camming surfaces which are mutually engageable with the opposite cam plate surfaces. A plurality of spring discs are telescopically mounted on the shaft and bias the first camming block into engagement with the second block applying a rotational force on the lever to move the pulley into tensioning engagement with the drive belt. A hub is adjustably mounted on the shaft and is in abutting engagement with the springs to adjust the amount of camming force exerted on the lever, and correspondingly, on the belt by the idler pulley.
