Development of a New Gear Measuring Instrument using Direct Drive Systems (1st report)

Abstract

The quality of gears is classified according to deviations by ISO 1328, and recently a system to evaluate gear measuring instruments is to be established. The purpose of our research is to develope a highly accurate gear measuring instrument with small uncertainty of measured values and a repeatability less than 1 micro meter.
To reduce the transmission errors caused by the mechanisms in conventional gear measuring instruments, a gear measuring instrument consisting of two direct drive axes, linear axis and rotary axis, is proposed and being developed by authors.
The basic concept and configuration of the measuring instrument are described in this paper.
