Abstract. It is difficult to imagine modern design of any unit and development of working drawings without the use of CAD elements. The Autodesk Inventor Professional solid-state parametric design system is a fairly powerful tool for performing design work and mechanical engineering drawings. But it should be noted that the existing gear generators in Autodesk Inventor can build cylindrical and bevel gears, even worm gears, but not hypoid. Therefore, when designing hypoid main gears of a car, difficulties arise in creating 3-D models of hypoid gears. The inability to directly build hypoid gears in the Autodesk Inventor gear generator does not allow for 3-D design of hypoid main gears, and this is a problem. This work is devoted to solving this problem, the purpose of which is to create a method for constructing a hypoid gear in the Autodesk Inventor program to provide the possibility of 3-D layout of hypoid main gear elements and further automated development of drawings. The method of achieving the goal is that two separate bevel gears are created in the Autodesk Inventor bevel gear generator, with the parameters of one gear corresponding to the parameters of the hypoid gear, and the second – the hypoid wheel, then a 3-D model of the hypoid gear is created as an assembly product from the hypoid gear and hypoid wheel models. The proposed method allows you to build a 3-D model of the hypoid gear in the Autodesk Inventor program, which allows 3-D layout of hypoid main gear elements and automated design of its design documentation. This increases the level of design productivity in the design office, and in the educational process, it increases the level of competence of applicants and their interest in learning.
