ABSTRACT:
An apparatus is provided for measuring the axial and radial runout of a peripheral groove formed in a pulley. The apparatus includes a base from which an upright rotating spindle projects. The spindle removably accommodates the pulley. A frame is adjustably mounted on the base and a carriage is disposed on the frame for independent adjustment relative thereto in substantially axial and radial directions with respect to the spindle axis. A carrier is mounted on the carriage for independent movement to selected positions relative thereto. A plurality of relatively spaced detector elements are mounted on the carrier. When the carrier is in a selected position, one detector element is disposed in close proximity to the pulley periphery. Each detector element is independently adjustable relative to the carrier in a substantially axial direction relative to the spindle. Means are provided which coact with the frame and carriage to position a portion of a selected detector element into aligned engagement with the pulley groove. The carrier and carriage are responsive as a unit to the substantially radial deflection of the detector element engaging the pulley groove. Fixedly mounted gauge means are provided for measuring the axial and radial deflection of the groove-engaging detector element upon rotation of the spindle.
