摘要：
The highest class in the Chinese national standard Gear Involute Artifact GB/T 6467-2010 is class-1，of which the tolerance of profile form deviation for class-1 gear involute artifact is around 1.0 to 2.1 μm，however，the measurement uncertainties of current commercial involute measuring instruments are not sufficient to measure class-1 gear involute artifact. In order to verify the manufacturing accuracy of the gear involute artifact developed by the high-precision gear research laboratory of Dalian University of Technology，Dalian University of Technology，together with the National Institute of Metrology of China，the Northeast National Institute of Metrology of China and the Chongqing Academy of Metrology and Quality Inspection of China，carried out a measurement comparison for a new kind of gear involute artifact with three base circle parameters numbered GIA db100-200-262：06. Based on the measurement results and uncertainties of the base radius and profile form deviation of this gear involute artifact provided by each metrology institute，the reference value of the actual base radius and the profile form deviation is calculated using the weighted average method. The normalized deviation of the measurement results is |En|<1，and the measurement results of each metrology institute are true and valid. Within the 95% confidence interval，the reference values of the four tooth flanks of the gear involutes the gear are ffα=（0.27~0.43）± 0.53 μm，which meet the requirements for the tolerance of the profile form deviation and evaluation range of class-1 gear involute artifact according to the Chinese national standard Gear Involute Artifact GB/T 6467-2010. © 2022 Chinese Academy of Sciences.
