The application and use of gear mechanisms in machines is now widespread in all industrial areas. With the development of science and technology, especially in the field of control and management of movements of executive members of technological equipment, the requirements for the accuracy parameters of transmissions in the drives of machinery are growing. This applies to parameters specified as torsional stiffness, reduction ratio, lateral play, play. High-precision reduction gears are precise, efficient and provide high-quality gears that are cost-effective, quiet and provide high performance. The term high-precision gears comes mainly from their manufacturers, especially Japanese companies such as Teijin Seiki, Sumitomo Cyclo, and the Slovak company Spinea also belongs to them with its parameters. From the point of view of development and research, these transfers can be classified as promising transfers.
