Introduction.

Production processes in most sectors of the national economy are carried out by machines, and further growth in material well-being is closely associated with the development of mechanical engineering.

The most important requirements for the designed machine include cost-effectiveness in manufacturing and operation, convenience and reliability of maintenance, reliability and durability.

To meet these requirements, parts must meet a number of criteria, the most important of which are strength, reliability, wear resistance, rigidity, vibration resistance, heat resistance, and processability.

Gears in modern industry are important. Due to their high efficiency, they are widely used in technology. The course project on machine parts is the first design work of the student and therefore its value is very significant. The study of the basics of design (design) begins with the design of the simplest units of machines - drives, gears. The experience and knowledge acquired by the student in the design of these machine units are the basis for his further design work, as well as for the implementation of course projects in special disciplines and a diploma project.
