Abstract: An improved chain speed reducer assembly comprising a drive shaft supported at one end by a first bearing block and by a second bearing block at the other end. Each of the bearing blocks has a shaft supporting bore that is axially displaced a predetermined offset distance from the central axis of the bearing block, and each of the bearing blocks is supported by a gear box frame so as to be selectively rotatable about the central axis of each bearing block. Attaching bolt connectors permit the bearing blocks to be secured at selected angular dispositions. This permits selective canting of the drive shaft, and when coupled with other similarly supported driven shafts supporting plural sprockets, separate strands of roller chains can be adjusted independently via the eccentric movement of the bearing block supporting bores upon selective rotation of the bearing blocks.
