Course Description

Learn and define the concept of epicyclic gearing is including some basic history and the differences among simple planetary gear systems, compound planetary gear systems and star drive gear systems. Cover concepts on the arrangement of the individual components including the carrier, sun, planet, ring and star gears and the rigid requirements for the system to perform properly. Critical factors such as load sharing among the planet or star gears, sequential loading, equal planet/star spacing, relations among the numbers of teeth on each element, calculation of the maximum and optimum number of planet/star gears for a specific system will be covered. Provides an in-depth discussion of the methodology by which noise and vibration may be optimized for such systems and load sharing guidelines for planet load sharing.

Learning Objectives

Upon completion of this course, you will be able to:

  • Restate exactly makes a gear system an epicyclic system
  • Calculate the total reduction ratio of an epicyclic system and that of a star system.
  • Identify differences and similarities between split power systems and true epicyclic systems.
  • Recognize when the use of a star drive system is preferred over a planetary system.
  • Understand the importance of equal planet/star gear spacing and how a system be designed with unequal planet spacing.
  • Interpret how the numbers of teeth selected for the individual gears in an epicyclic or star drive gear system affect the noise and vibration characteristics of the system.
  • Identify are the advantages of selecting odd numbers of teeth for the planet/star gears?
  • Evaluate the numbers of teeth on the sun, planet and internal ring gear not arbitrary and what are the relations that must be maintained among these tooth numbers and why
  • Explain how does the design of the carrier affect the overall performance of these complex systems
  • Determine how does input speed affect the design of an epicyclic system and why are the speed concerns different for epicyclic and star drive systems
  • Restate how the selection of the “fixed” member in a planetary system affect the ratio and relative rotation directions of the input and output shafts?
  • Understand the design and use of load balancing systems including floating sun gears, and floating ring gears.
  • Understand the differences between flexible and a rigid carrier design approaches.
