“…The mandrel shaft tilt does not change the tilt angle of each measurement point. 26 Therefore, the effect on each gear tooth is the same and any gear tooth can be taken for error analysis. This tilt causes the incident light to shift in x o and z o directions, as shown in Figure 6.…”

The Line laser gear measuring center (LLGMC) is an innovative gear measurement equipment that offers high efficiency but low accuracy. One crucial factor that influences its measurement accuracy is the presence of geometric errors. In this study, we conducted a thorough analysis of these geometric errors and proposed a method for modeling spatial errors. Instead of directly considering the geometric errors, we replaced them with the installation errors of the gear and line laser probe. This approach simplifies and improves the error transmission relationship. Subsequently, the installation errors are converted into a unified representation of the height error of the incident light from the line laser. A spatial error model that considers nine installation errors is then further established. By numerically calculating the sensitivity of different error sources, we effectively identified the errors that have a significant impact on the accuracy of LLGMC. Moreover, accuracy distribution is carried out to ensure that LLGMC can meet the measurement accuracy requirements for gears with a tolerance class of 6. This article provides a theoretical foundation for the structural design and accuracy assurance of LLGMC during the research and development phase.

“…The locating errors of the mandrel includes the eccentricity error and the inclination error. Acording to the article [22], the effect of the eccentricity error on the gear helix deviations is counted for about 0.24%. That is to say, the eccentricity error of 10 µm can only cause gear helix deviations of dozens of nanometers.…”

Dalian University of Technology, China (DLUT) successfully developed class-1 spur gear artefacts. However, the expanded uncertainty U95 of the existing instrument for measuring gear helix deviations is more than 1/3 of the class-1 gear helix tolerances, which cannot meet the measuring requirements of the helix deviations for the class-1 spur gear artefacts. In order to solve these problems, the influences of the mandrel locating error on the gear helix deviations are analysed, and a novel instrument for measuring spur gear helix deviations to submicron accuracy is designed. The instrument is optimized for the measurement of specific gear types (external teeth, medium module, with through-hole, reference diameter ≤126 mm). The expanded uncertainties U95 of the instrument for measuring the total helix deviation Fβ, the helix slope deviation fHβ and the helix form deviation ffβ are 0.23 µm, 0.20 µm and 0.18 µm respectively. This is less than 1/3 of the class-1 gear helix tolerances (the total helix tolerance FβT, the helix slope tolerance fHβT and the helix form tolerance ffβT are 2.4 µm, 1.6 µm and 1.8 µm respectively: ISO 1328-1:2013). Verification measurements with a calibrated measurement standard show the proficiency.
