“…A TESA inductance micrometer (a GT21HP high precision probe and a TT80 electronic length measuring instrument) was used to measure the involute profile with a measurement uncertainty of 𝑈 95 = (0.07 + 0.4𝐿) μm (𝐿 is the measured length in mm). The positioning method of the probe can be found in [18].…”

Gear involute artifact (GIA) is a kind of calibration standard used for traceability of involute metrology. To machine GIAs with sub-micron profile form deviations, the effect on the involute profile deviations caused by the geometric deviations and 6-DoF errors of the machining tool based on the double roller-guide involute rolling generation mechanismwas analysed.At the same time, a double roller-guide involute lapping instrument and a lapping method for GIAs was proposed for lapping and in-situ measuring the gear involute artifacts. Moreover, a new GIA with three design base radii (50 mm, 100 mm, and 131 mm) was proposed for more efficient calibration and was machined with profile form deviations of 0.3 μm (within evaluation length of 38 mm, 68 mm, 80 mm, respectively, measured by the Chinese National Institute of Metrology), and the surface roughness Ra of the involute flanks was less than 0.05 μm. The research supports small-batch manufacturing for high-precision GIAs.

“…In order to reduce the influence of the probe locating accuracy on the measurement results, a micro-displacement transfer lever is designed [24] as shown in figure 6. The micro displacement transmitted to the probe of the inductance micrometre is exactly equal to the gear helix deviations by using the cross-spring lever without backlash.…”

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.

The torque fluctuation characteristics of noncircular planetary gear (NPG) systems are difficult to obtain, and there is no clear analysis method and evaluation method for transmission efficiency, which seriously affects their service performance. Given that, this article establishes a torque fluctuation model for NPG systems based on the principle of gear meshing and differential geometry theory and methods, taking into account factors such as actual working conditions and speed loads. And proposed, the comprehensive transmission rate, a new method for evaluating the efficiency of NPG systems. By analyzing the actual working conditions of NPG systems, the influence mechanism of alternating load and speed on torque fluctuation and transmission efficiency was explored. The research results indicate that the alternating load can cause an increase in system impact and vibration. The comprehensive transmission rate of NPG systems decreases with increasing rotational speed and increases with increasing load, and is more sensitive to changes in rotational speed. The trend of comprehensive transmission rate and transmission efficiency of NPG systems is basically consistent, indicating that the proposed method of using comprehensive transmission rate to evaluate transmission efficiency is a practical and feasible analysis method. The research results can provide a new method for dynamic measurement and evaluation of torque and transmission efficiency of non-circular gear transmission systems.
