SUMMARY

The discussion centers on selecting a gearbox for wind turbine applications, specifically requiring an input RPM of 1 and an output RPM of 1500. Participants emphasize the importance of additional specifications such as power, lifetime, cost, weight, size, and efficiency. A referenced paper highlights that while wind turbine gearboxes are designed for a 20-year lifespan, they often fail within 5 years, necessitating frequent replacements. This underscores the critical need for thorough research and precise specifications when selecting gearboxes for wind turbines.

PREREQUISITES
  • Understanding of gearbox specifications and performance metrics
  • Familiarity with wind turbine operational parameters
  • Knowledge of mechanical engineering principles related to gear design
  • Awareness of industry standards for gearbox reliability and efficiency
NEXT STEPS
  • Research gearbox selection criteria for wind turbine applications
  • Study the impact of gearbox efficiency on overall wind turbine performance
  • Examine case studies on gearbox failures and maintenance strategies
  • Explore advancements in gearbox technology for renewable energy systems
USEFUL FOR

Engineers, wind turbine designers, and procurement specialists involved in renewable energy projects will benefit from this discussion, particularly those focused on gearbox selection and reliability in wind turbine applications.

TL;DR
This post to share with you how to select the gearbox from market and what are the most important parameters to do that
Hi everybody

I want to buy a gearbox very near of the one used in the wind turbine

I need the input RPM to be 1 rpm and the output to be 1500 rpm

Please your support to can find this gearbox

What research have you done so far? What have you found out?
 
What are your requirements? You mention RPM. What about power? lifetime? cost? weight? size? efficiency? Your question is so open, we can't provide specific answers.

This paper discusses many of the problems with such gearboxes.

The typical design lifetime of a utility wind turbine is 20 years, but the gearboxes, which convert the rotor blades rotational speed of between 5 and 22 revolutions per minute (rpm) to the generator-required rotational speed of around 1,000 to 1,600 rpm, are observed to commonly fail within an operational period of 5 years, and require replacement.
