Gear Metrology for Wind Energy Systems (WES)

Tutorial at euspen SIG Meeting: Precision Engineering for Sustainable Energy Systems
October 13, 2021
Time to be announced later
PTB, Braunschweig

Gears and gearboxes are an important part of many wind energy systems. Small tolerances account for high demands on manufacturing metrology for such components with complex geometry.

This tutorial will show attendees how we currently measure gears, discuss some limitations of these processes and introduce participants to some of the strategies that are being researched.

Tutorial programme:

  • Why do we measure gears?
  • What do we measure? – Gear geometry introduction
  • How do we measure gears? Typical measuring machines and methods
  • What do we evaluate? Classical gear evaluation parameters –with ISO 1328-1:2013.
  • What do we get wrong? Contributions to measurement uncertainty, traceability and classical calibration strategies for large gears
  • What is new and why do we need to improve measurement methods?

    • Full surface scanning with tactile and optical probes
    • Holistic evaluation of involute gears
    • Evaluation of harmonic content- (some candidate methods)
    • GPS compatible strategies- the challenges and some possible solutions

  • How do we use the holistic gear measurement data? Interfacing measurement data with CAD/TCA models and Digital Twins.

Intended for:
This tutorial is aimed at technical staff, graduate and postgraduate engineers, post-doctoral researchers, operators and managers of wind energy systems responsible for purchasing, repairing or maintaining these facilities.

euspen SIG Meeting: Precision Engineering for Sustainable Energy Systems

October 13-14, 2021
PTB, Braunschweig

Precision machines have long been at the forefront of one industrial revolution after another to enable the turning of ideas into the economical production of physical objects. In all likelihood the emerging Sustainable Revolution could be the start of a new golden age for the planet, humanity, and precision engineering.

Whilst there is no shortage of renewable energy systems available at ever-decreasing costs, a concern is they are not evolving fast enough to help us economically transition to a low carbon economy. The purpose of this workshop is thus to bring together people from academia, industry, and government to share experiences with using precision engineering principles to help develop new ideas and manufacturing systems to reduce production and ownership costs related to realizing a global carbon neutral (or ideally negative) economy.

Areas of interest include automated precision production of components and systems ranging from manufacture of solar cells and panels to their installation and maintenance; to ever larger wind turbines on and offshore including in-situ manufacturing of ever larger elements; to energy storage systems from batteries to hydro power systems.
