This workshop introduces the essential fundamentals of cylindrical gears and provides a comprehensive overview of their basic principles. It covers the key aspects every engineer needs to understand when working with cylindrical gears. In addition, the course delivers in-depth knowledge and practical skills in the dimensioning and optimisation of cylindrical gears, addressing more advanced technical topics.
Designed for young professionals and experienced engineers alike, this seminar is ideal for engineers, designers, technicians, and anyone looking to refresh and deepen their knowledge of cylindrical gear technology.
