The analysis of the formation of the radial run-out of a gear rim
In the article there isis stated the analysis of the formation of the radial run-out of a gear rim, which is one of the main kinematic errors of a cogwheel. In the analysis of radial run-out the scheme of blank installation when processing on the gear-hobbing machine of model 5310 is considered. As research objects there are used helical and straight-toothed cogwheels with the m=2 module, number of teeth z=27. The measurements are made using universal metrological means. The dimensional chain of blank installation is the error percent of a given dimensional chain is calculated from the results of experimental studies, taking into account with this practical component of the experiments. The correlation analysis with creation of the graph of dependence of the total error of the component links of the dimensional chain with respect to the radial run-out of the ring gear of the wheels obtained during the measurement is presented. A correlation analysis of these dependencies is performed.
