Live Online Seminar: Basics of Gearbox Design Requirements – Concept – Design



Fundamental properties of a gearbox, like load capacity and NVH behavior, can be positively influenced already in a very early stage of gearbox development. This seminar imparts the knowledge of sizing the most important gearbox components in general and answers the following questions in detail:

  • What are the most important requirements to be defined when starting a new gearbox design and how is the design affected when these requirements are changed?
  • How are the most important components like gears, shafts and bearings sized and how can they be optimized regarding load capacity and NVH?
  • What is to be regarded in the first rough housing design?
  • How can size and weight of the gearbox assembly be estimated already in a very early phase of design?
