Abstract
A tachometer is mounted to an end frame of a motor. The end frame includes an end mount plate. An adjusting plate located within the recess and coupled to the mount plate through a plurality of radial coupling units and a plurality of axial spring loaded clamp units. Both coupling units are circumferentially spaced about the mount plate and the adjusting plate. Each radial coupling unit includes radial set screws in threaded openings in the mount plate and engage the periphery of the adjustment plate for radial positioning of the adjustment plate. Each axial coupling unit is a clamp unit located centrally between the radial coupling units, and each includes a clamp screw adapted to pass through a clearance hole in the adjusting plate and threaded into an appropriately threaded opening in the mount plate. A preload Belleville washer is located between the head of the clamp screw and the adjustment plate. Each clamp unit also includes a pair of axial set screws, located one to each side of the clamp screw. In assembly, a suitable indicator is coupled to the motor shaft and the position of the adjustment plate within the mount plate is accurately located in accordance with selected ch…
