The lifeline of the gearbox is its lubrication system, critical for supporting the drive under all modes of operation. Continued reliability, successful operation and long life of power transmission equipment are largely dependent upon the constant supply of lubrication oil of proper quantity, quality and condition. 

Premature equipment failure happens when a lubrication system fails to protect working gearbox components, remove and dissipate heat, and remove wear particles.

Understanding the role and importance of a lubrication system in the overall life of a gearbox is key to effective maintenance. This paper provides maintenance professionals with the tools to properly understand how to extend the life of their gearbox with proper lubrication. It will explore:

  • Available lubricant types
  • Systems used to supply lubricant throughout a gearbox
  • Proper maintenance functions for sustaining a functional, effective lubrication system
