Pitch and Yaw Gear Drives

Turning with the wind requires an oil that will respond

Both pitch and yaw drives must turn with the direction of the wind to optimize blade speed and electricity generation. To do this, a system must exist to rotate the blades and nacelle.

There are two different methods used to turn these drives 

  • With a gearbox
  • With a hydraulic system

Both methods perform the same function and have the same end goal: a high-quality long-lasting oil to keep systems turning throughout all application extremes.

 

 

Pitch Drive Gearbox

FUCHS has developed RENOLIN UNISYN CLP 220 to meet the requirements for gearboxes.

It is a fully synthetic, highly additized OEM approved gear oil specifically designed to provide long life and keep the gearbox running.

Hydraulic Pitch System

Hydraulic systems require a premium high VI oil with a robust additive package to ensure the system turns as needed on demand.

RENOLIN UNISYN B HVI 32 was developed to meet the stringent requirements of this application. As an OEM approved oil, it provides the responsiveness and life required within the wind  industry.

 

WHETHER A TURBINE HAS A GEAR OR HYDRAULIC DRIVE, FUCHS has a SOLUTION.
