Abstract
The specification discloses apparatus for aligning rotatable in-line machine shafts. In a preferred embodiment, the invention provides an alignment system having a sensed point positioned for rotation with the shaft to be aligned to provide a reference point against which misalignment is measured. The position of the sensed point is adjustable in three-dimensional space by an adjustment system so that the sensed point may be easily secured in a desired location to eliminate errors attributable to movement of the sensed point or improper location of the sensed point. In addition, the alignment system provides a capacitive displacement system to more accurately sense the sensed point, binary blocks to facilitate proper vertical positioning of the sensed point, and an improved chain assembly to facilitate mounting of the alignment system and to reduce errors of the type common to conventional alignment systems.
