随着社会进步和科技发展，人们对传动产品质量的要求越来越高，而高品质塑料齿轮作为传动关键零部件被应用在高端精密产品中，但塑料齿轮的快速测量问题尚未得到完全解决。为此，本项目以塑料齿轮测量为研究对象，将工业CT引人塑料齿轮的快速测量中，研究实际齿轮的3D大数据建模方法，提出工业CT测量齿轮的标定方法及其样板，进而研究提升测量精度的途径，为工业CT实用性测量提供支撑。基于工业CT测量获得的塑料齿轮的大数据，提出塑料齿轮的质量评定新指标，从而形成系统化的塑料齿轮质量评价体系。本项目研究对促进我国塑料齿轮行业的发展，具有极大的促进作用。

With the development of society and technology, people have higher requirements for the quality of transmission products. High-quality plastic gears are used as key components of transmissions in high-end precision products, however, the fast measurement of plastic gears has not been completely solved. For the above reason, this project takes the measurement of plastic gears as the research object, and takes use of industrial CT into fast non-contact measurement of plastic gears, and introduces 3D large data modeling of actual gears, and proposes the calibration method and model of industrial CT measuring gears. Furthermore, it studies the ways to improve the measurement accuracy, and provides support for industrial CT practical measurement. Based on the large data of plastic gear obtained by industrial CT measurement, a new index of quality evaluation of plastic gears is proposed to form a systematic plastic gear quality evaluation system. The reaseach of this project has greatly promoted the development of China's plastic gear industry.
