What are the main functions of transmission oils?

  • protection of friction surfaces from wear, jamming and other damage.
  • minimize friction energy losses.
  • heat removal from friction surfaces.
  • reduction of noise and vibration of gear wheels, reduction of shock loads.
  • For gear oils, as well as motor oils, base oils of various types are used - synthetics, mineral oils or semi-synthetics. It is the base that has the greatest influence on the viscosity and temperature properties, with the highest viscosity index in synthetic lubricants. As for the operational properties, they are determined by the additives introduced - anti-corrosion, anti-tear, anti-wear.
