【 摘 要 】

A study of single-stage reducers, made in a horizontal pattern, having the same technical characteristics and a similar configuration, but differing in the material hardness of the gear pair parts has been carried out. The design of reducers, the determination of the mass-dimensional parameters of the parts and the entire product assembly was carried out in one of the CAD programs of three-dimensional modelling. For identically designed reducers, a comparison of the mass and dimensions of all the parts was made. The data on the total masses and overall dimensions of the assembly items, as well as the results of the heat treatment time of gear wheels and toothed wheels are given. The parts dimensions of which undergo the greatest changes in size due to the replacement of gear and toothed wheel materials are identified. The paper gives the calculation of the machining time and the calculation of the cost for the production of a batch of 10 thousand pieces per unit of production, taking into account the cost of raw materials and materials, heat treatment, energy and technical needs, wages and social deductions, repair and maintenance of equipment, general production and selling expenses for these parts. As a result, data were obtained about the difference in the cost of production of a batch of reducers under study.
