【Abstract】 For the large gear of mine mill with a diameter of more than 8 m,the detection of tooth profile accuracy was limited by the volume of detection equipment.Based on this,the application of laser tracking technology in gear detection was introduced.Then,a mathematical model of tooth profile was established and a new detection method was developed to realize the in-situ measurement of large gear tooth profile,which solved the problem of precision detection of large gear tooth profile with a diameter of more than 8 m,and provided a guarantee for gear processing quality.更多还原
