Abstract
To control the entire set of gear gear parameters, it is necessary to use a number of measuring devices and complexes simultaneously. Many of them are outdated, non-automated, have no access to computer tools and do not provide the current level of accuracy, informativeness and speed. Therefore, the article proposes a block diagram of the information-measuring and diagnostic channel, by means of which the technical condition of the toothed wheel is evaluated at the average integral speed of wear of the cutting tool. Error analysis for real operating conditions at the stage of previous studies, when the list of components of the main error is not known and their quantitative assessment is not carried out. Objects of research in this work are gear transmission with an engraving profile. 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 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, expansion of the range and range of measured parameters. Manufacturing of new modifications of domestic measuring devices on the basis of new management principles and equipment of leading foreign manufacturers in the field of control of evolvent. The complex of works on creation of a system for ensuring the unity of the geometry of the geometric parameters of gear gears is considered. This requires revision, systematization and development of methods and means of metrological support. The mathematical description of the involute curve of the toothed wheel by the method of triangulation of multi-directional regions and description of the geometric model of the evolvent is proposed. The results were analyzed and recommendations on the application of the description method to the cylindrical wheel with an engraving profile were given.
