This is the progress powering tomorrow. Allen Hall: Welcome back to the Uptime Wind Energy Podcast Spotlight, where we tackle the technical challenges and innovations in wind energy. I'm your host, Allen Hall, joined by my co host, Joel Saxum. We're excited to welcome back one of our most popular guests, Cory Mittleider from Malloy Wind. In his previous appearance, Cory shared his expertise on main bearing failures. And many of you reached out asking for a deep dive into gearbox bearings. Today, Cory returns to do exactly that. As Malloy's business unit manager, he and his team have diagnosed and solved countless gearbox bearing issues across different turbine platforms. Having spent over 15 years in power transmission, Cory has become a specialist in understanding why these critical components fail and, more importantly, how to prevent those failures through better bearing selection and maintenance practices. Cory, welcome to the Uptime Wind Energy Podcast Spotlight. Thanks for having me again. All right, so we've got a lot of requests to hear about gearbox, bearing, and what the issues are with those bearings. Gearboxes is something I know a little bit about. But you're the expert. I hear a lot of complaining from the field. What is happening to gearbox bearings at the minute? Cory Mittleider: Sure. Gearbox bearings has been an interesting one for me. So when I started in wind in 2011, it was generator bearings and gearbox bearings is where I started learning about this stuff. A lot of the generator stuff was electrical fluting damage. That's pretty well figured out how to avoid that. The gearbox one was a little more complex than that. And I don't know if you've heard of. NREL's Drivetrain Reliability Conference that's happened for the last 12 plus years now. That's a recurring topic for the last every single year, right? Is gearbox bearing failures. A lot of the conversation that started back in the day and is still going on is around what they call white etching cracking or white etching failures. And back, in say, 11 and 12, A lot of the conversation was around was around that. It was around, the oils in the gearboxes. It was around coatings and bearing types and how they could affect the bearing itself to improve the life. And, specifically when it comes to gearbox bearings That was really hard back in the, the service providers and the operators themselves weren't used to having to replace gearbox bearings. They maybe weren't even planning on having to replace gearbox bearings, right? But they started to see these problems. They started to get their head around the scope and how to identify them early and started to dig into it.
