| Research Abstract |
The performance of gears, e.g.for vehicles, is influenced much by 3 dimensional tooth flank form of 100nm order and therefore it is necessary to accomplish the high accuracy of gear measuring machine (gear checker) used for quality control. ISO quality guarantee system requires suppliers to clarify the measurement uncertainty of measuring machine for quality control. In this research, virtual gear checker, a simulation model of gear measuring machine, is proposed, where the mechanism and the motion of the machine and a variety of errors of it are incorporated. Virtual gear checker outputs the virtual measured data with errors and it clarifies the uncertainty of gear checker measurement. The followings are accomplished in this research.
(1)Simulation model of gear measuring machine (Virtual gear checker) program was developed, where the mechanisms and errors of the machine are considered. It is confirmed that virtual gear checker outputs reasonable virtual measuring data and the uncertainty of measurement. Virtual measurement was applied into the measurement of spur gear artifact and helical gear artifact and its uncertainty is evaluated.
(2)The influence of the errors of gear checker on measured data is investigated by virtual gear checker. The inspection/calibration method by using gear artifacts is proposed.
(3)Highly precise measuring method of gear artifact by ultra precise contact probe 3D measuring machine and the analyzing method of measured data are developed. It contributes to high accuracy calibration of gear artifacts.
(4)Structure of precise involute artifact, on which inspection/calibration system of gear checker is based, is investigated.
