EUROTRANS Gear Weeks 2021
Geometry and Design
EUROTRANS continues to work with our world-class instructors toward creating online classes that meet your specific needs. In 2021, EUROTRANS Gear Trainings will be held online, with live online presentations by top industry experts - three weeks packed with specialized gear design training.
This comprehensive online course has been developed by EUROTRANS, the European Committee for Power Transmission Engineering, in cooperation with FVA Software & Service and leading German gear experts.
This course is intended for people with a basic engineering background who are active in the gears sector, and provides updated knowledge on geometry and design aspects of gears and gear systems. The course will be held in English, contributing to the improvement of participants' language skills by interacting with experts and their peers from other countries.

This module presents the Geometry Fundamentals of Involute Gears. The meshing of two mating gears will be examined in detail based on fundamental gear laws. The main geometry parameters will be derived from the meshing requirements. Fundamental relationships will be explained using examples (how to mesh gear pairs with different modules for each mating member/how can the same gear flanks be generated with different pressure angles, tool pitch circles, etc.). The focus will be on the descriptive parameters of tooth contact and contact ratios. Detailed animations will be used to illustrate relationshps.
This module provides an overview of bevel and hypoid gears, covering the basics of geometry, load capacity, and manufacturing. Geometry parameters will be examined, starting with an analysis of the similarities and differences between bevel and hypoid gears. The basics for determining load carrying capacity using standard methods or higher-level methods (loaded tooth contact analysis – LTCA) will be shown. Key aspects of different gear production processes will be explained (face milling, face hobbing, generated, non-generated).
This module explains the fundamentals of planetary gears, focusing on kinematics, power flow, and efficiency. It will begin with an analysis of the basic differences between standard and planetary gears. The power flows will be derived by analyzing the kinematics based on the Willis equation and examining torque relationships. The complex power flow of planetary gears, consisting of meshing and coupling power, will be systematically explained and related to the overall efficiency.
Standardized calculation procedures are required to ensure reliable proof-of-design calculations and comparability of products. Standards such as ISO 6336, DIN 3990, and AGMA 2101 provide uniform rules for calculating the load capacity of cylindrical gears. This webinar will provide an introduction to the application of these standards.
Evaluation of the local tooth contact provides more detailed results than the standard calculation. The load capacity and noise excitation of gears can be further optimized by selecting suitable micro geometries. This webinar provides an introduction to the application of these local calculation methods.
Using the FVA-Workbench as an example, this webinar will show how highly advanced calculation tools can be used to support the transmission design process.
Different materials are used in different gear applications. Different heat treatment methods can be used to optimize the manufacturing and load capacity of materials. Additional surface treatment methods offer further potential for improving the load capacity.
Standards and guidelines describe new and proven calculation methods for optimizing the gear layout in the design phase to avoid damage. The possibilities and limitations of the methods will be demonstrated.
Standards and guidelines describe new and proven gear lubricant test methods, in addition to the physical and chemical characteristic values, for reliably selecting lubricants for the specific application. The results of the tests are implemented in the corresponding calculation procedures as "strength values" for the lubricant.
