Gear PCD runout checking device

Concept Engineers manufactures gear PCD run out checking device. As the name implies, this is used for inspecting the run out of pitch circle diameter of a gear. This is a high precision measuring unit with a repetitive accuracy of less than 0.002 mm. The base, the table, the tailstock and the head are made out of close-grained castings. The base is having a box structure adequately ribbed for rigidity. Pillar and other ware parts are made out of alloy steel and hardened appropriately. The gear to be inspected is mounted on an arbor (either on a Concept hydraulic expanding arbor or on a taper arbor). The arbor along with the gear is in turn mounted between center of the device. The tailstock could be moved by loosening the knob. Further adjustment can be made by loosening the knob. The gear can be positioned to the center of the ball by rotating the knob. The head can be moved up or down by rotating the handle to pre-load the dial. When lever is moved, the dial retracts, the gear is indexed and the lever operated to obtain reading. The operation is repeated to obtain the total PCD error. The dial can move up or down by 10 mm. The table can be moved in X axis by 100 mm. The head can be moved up and down by 75 mm in Z axis. Center height 100 mm. Admit between centers 275 mm.
