Course Description

Knowledge of gears and gear systems is critical in today's mechanized world. This course covers gear basics, installations, maintenance and troubleshooting as well as parallel and perpendicular shaft configurations; attributes of gears; installation procedures specific to spur, helical, bevel, miter and worm gearing; and types of wear associated with open gearing systems.

Course Objectives

  • Being familiar with the different types of gears
  • Understanding how to calculate critical dimensions of gears
  • Being familiar with inspection procedures for spur, helical, bevel, miter and worm gear sets
  • Being able to determine causes of failure
  • Understanding safety procedures with open gear systems

Who Should Attend?

  • Maintenance Mechanics and Supervisors
  • Field Service Technicians 
  • Power Transmission Distributors
  • Those who are interested in learning about different types of gearing, gearboxes
