Abstract
The article discusses the method of designing a cylindrical gear pair in Autodesk Inventor, which allows for its automated design and verification calculation within CAD software with the reconstruction of the geometry of the 3D model of the gear pair. The software product created by the authors makes it possible to obtain data on the required hardness of steel for the gear pair immediately after receiving the technical specifications for a wide range of operating torques, gear ratios and other parameters set in the technical specifications to select the best option from all possible. The paper presents the results of studies using the created software product: the values of the hardness of the material, the mass-dimensional parameters for the range of transmitted torques 250-710 Nm, gear ratios 2-5, and overall dimensions determined by the center distance of the gear transmission in the range 125-180 are obtained mm.
