INNOVATIVE APPROACH TO TEACHING THE SUBJECT "MACHINE PARTS"

Abstract

Training engineers in the field of mechanical engineering technology, technical operation of cars, who will be in demand in the labor market and who have knowledge, skills and abilities that correspond to the modern level of development of science and technology, is an urgent task.

The article considers innovative approaches to teaching the academic discipline "Machine Parts", which are implemented at the Department of Mechanical Engineering and Car Operation of Brest State Technical University.

In order to automate the process of design and calculation, development of three-dimensional models and working drawings of gears, it is proposed to use the Russian import-independent three-dimensional design system KOMPAS-3D V21 LLC "ASCON - Design Systems" with the applications "Shafts and Mechanical Transmissions 3D", "Shafts and Mechanical Transmissions 2D", which include the KOMPAS-GEARS module.

In the educational process, it is proposed to use a simplified methodology for the design and calculation of gears, which ensures the independence of calculation formulas from the system of units of physical quantities. This methodology also takes into account the recommendation that in the course of educational design, the reduced modulus of elasticity of the materials of the contacting teeth of the gear and wheel should not be taken out from under the radical sign in the calculated strength dependencies for cylindrical gears. To implement this approach, an application based on the Microsoft Excel spreadsheet processor has been developed and implemented in the educational process.

A methodology for calculating the modified life of bearings in accordance with GOST 18855-2013 has also been implemented in the educational process and is used in practical classes and course design for the discipline "Machine Parts".
