Parkinson gear tester is used to test the error in the gear. Here the carriage has two spindle. One main gear is fixed in one spindle and another testing gear is fixed in the second spindle. They can slide both side and these gears are mounted in mesh by spring pressure. When the gear are rotated, the moment of sliding carriage can be measured by the dial indicator. This values are recorded in the recorder. The spindles can be adjusted so that axial distance is equal and scale is attached to one side and vernier to the other side for measure the centre distance.

If errors occur in the tooth form moment of carriage due to the error in the pitch and tooth thickness. This moment is indicated in the dial gauge. The maximum gear diameter 150 mm can be tested.
