Abstract
A mechanism which maintains drive belt tension substantially constant when the drive belt is mounted on sheaves with a non-fixed center distance such as the sheaves and belt utilized in vibratory earth compaction equipment, shakers and the like where off-centered weights are rotated at high speeds to obtain desired vibrations. The mechanism includes a driven sheave that is mounted eccentrically on the rotating shaft which supports the off-center weight with the eccentricity of the eccentrically mounted sheave being in the same direction as the offset of the off-center weight. This arrangement allows the center distance between the drive sheave and driven sheave to remain relatively constant thus retaining the drive belt tension relatively constant.
