Abstract

Gears are used in many machineries and it is important to make their accuracy higher and improve their performance. Gear vibration and noise is a severe problem for automobiles. It is influenced by micron-meter-order accuracy of tooth of gear and therefore inspection of gears is necessary using gear measuring instruments. Test of accuracy of gear measuring instruments is important for quality control. In most cases, a gear measuring instrument is calibrated by an artifact with higher accuracy than the calibrated instrument. However, conventional artifacts have a problem in accuracy because of its complicated form. In addition, various testing methods exist depending on measuring machine companies because there is no standard on testing method of gear measuring instrument. This paper introduces a new evaluation method of involute artifact, newly developed artifacts, a developed testing method of gear measuring instruments, and Japanese Industrial Standards concerning them.
