ESTIMATION OF THE SYSTEMATIC AND RANDOM COMPONENT OF THE MEASUREMENT ERROR OF CYLINDRICAL GEAR WHEELS

Abstract

In order to control the entire set of gear wheels parameters, it is necessary to use a whole range of measuring equipment and complexes at once. Many of them are outdated, unauthorized, have no access to computer tools and do not provide a modern level of accuracy, informationality and speed. To date, the metrological control of gear wheel parameters is based on a large number of measuring equipment. All of them have a limited range of measuring parameters, different accuracy and range of measured values. The complex of works on creation of a system of unity of geometric parameters of gear gears is considered. This requires revision, systematization and development of methods and means of metrological support. The reference base in the field of control of the gear draw gear is considered, which requires its creation on the basis of a detailed analysis of the new principles of measurement, the need to justify their accuracy, the expansion of the range and range of measured parameters. Therefore, the article proposes an estimation of the systematic and random components of the measurement error of cylindrical gear wheels. The analysis of errors for real operating conditions at the stage of previous studies, when the list of components of the basic error is not known and their quantitative assessment is not carried out.
