In order to improve measurement accuracy  a measuring instrument is developed for radial composite deviations of high-precision master gear in the paper. This instrument uses the structure of spring-suspend swing span to overcome the shortcomings of large rotation errors  low sensitivity  low resolution and large measuring force appearing in the traditional combination-type gear inspection instrument. Artificial intelligence technology is used to improve the efficiency and accuracy of this instrument. The result is that the measuring apparatus is able to meet the requirement and improve efficiency through the measuring experiments on master gears of precision grade 2 with modulus 2 mm and 3 mm  respectively. 2010 SPIE.   Analysis of a precise instrument for measuring reference level involute (EI CONFERENCE) 会议论文 Third International Symposium on Precision Mechanical Measurements, August 2, 2006 - August 6, 2006, Xinjiang, China Lou Z.; Wang L.; Wang X.; Ma Y.; Zhang Y. 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/25 Reference level involute is used for evaluating other involutes  but it is very difficult to measure reference level involute exactly. Nowadays the available methods for measuring precise involute include single base disc mode  electronic generation mode  and CNC three-coordinate mode. But measurement accuracy of the modes above is not suitable for reference level involute. A precise instrument for measuring reference level involute  double base discs instrument  is introduced. It is consistent with generation principle of the involute entirely. Besides having the advantages of single basic disc instrument  the instrument can remove Abbe error caused by the stylus  and has no pressure deforming. The instrument's structure is described. The main sources of measurement errors are analyzed and methods for compensation are presented. Finally  uncertainty of the instrument is given  which meets reference level involute test specification.
