ABSTRACT:
A cylindrical alignment housing is fixed to a housing of one of two axially aligned items of equipment. A cylindrical bearing housing is concentrically positioned around the cylindrical alignment housing, such that the cylindrical bearing housing is rotatably supported at a given position on the cylindrical alignment housing, which is fixed to the housing of the aforesaid one item of equipment. A mechanical coupling is provided between the bearing housing and the shaft of the other of the two equipment items that the bearing housing and the shaft will rotate in concert. A laser is positioned on the rotatable bearing housing and a prism is positioned on the other of the two items of equipment. The cylindrical bearing housing and the shaft of the aforesaid other equipment item are rotated together in concert, and measurements are taken using the laser and prism to determine whether the shafts are properly aligned with each other.
