Research on Tooth Wear Testing Technology of Face Gears Based on Reverse Engineering
Abstract
In order to obtain the location and size information of the wear area of face gears, a method of gear surface wear inspection based on reverse engineering is proposed. According to the measurement principle, the conversion matrix of the measuring coordinates is deduced; by measuring the tooth profile deviation and with the error compensation algorithm, the compensation point of the measuring point is obtained and the control equation of NURBS surface fitting is presented; a test bench is built, and an example operation is carried out to compare and analyze the standard tooth surface and the worn surface. The data in the unworn area is well matched, and the data points in the worn area are clear and free of noise. Therefore the use of reverse engineering technology in the face gear wear detection method is correct and feasible, and it provides a prerequisite for the future of green remanufacturing.
