Gearbox solutions

Overview

The main gearbox REDULUS GPV converts the slow rotor speed into high-speed at the input into the generator. Rexroth supplies gearboxes suitable to the needs of the specific wind turbine. 

Main Gearboxes REDULUS GPV for Generator Ratings up to 2,000 kW

• Compact design due to combining a planetary stage with two spur gear stages
• Compliance with Rexroth design guidelines to ensure maximum service life
• Proven gearbox concept
• Low-noise characteristics

 

Differential Gearboxes REDULUS GPV-D for Multi-Megawatt Turbines

• Slender and compact due to differential design concept with two planetary stages, one differential and one spur gear stage
• Compliance with Rexroth design guidelines to ensure maximum service life
• Weight reduction compared to conventional concept
• Low-noise characteristics
• Easy to service due to modular design

 

FAST technologies can participate in refurbishment and changeover programs, with stock replacement items for many different turbine models. Eliminating costly downtime issues, with scheduled maintenance change outs and monitoring programs.
