Drivetrain Integration

Flender unveils the next generation of wind gearboxes

Logistics, transportation and maintenance have always been critical challenges in wind turbines. There’s truth to the notion that large components can cause bigger headaches on their massive size and scope alone. A smaller, compact drive solution can help eliminate today’s renewable energy challenges while reducing costs.

The main objective of this study is to perform an experimental evaluation of the structural model of a five-planet first planetary stage from a modern 6MW wind turbine gearbox.

Grinding

The trend towards hard fine finishing of gears for automotive transmissions is accelerating. In recent years, the focus has been on increasing the efficiency of gears in order to make optimum use of the narrow gear ratio range, gear by gear, and to reduce fuel consumption. Surface finish, in particular, is under increased scrutiny since it plays such a decisive role in achieving the noise and efficiency requirements of gear units for today’s EV applications.

Skiving Tools

Klingelnberg recently invited customers to its first Open House in Saline and the two-day event did not disappoint. Customers from major automotive, off-highway, construction and agriculture OEMs attended a morning of technical presentations before heading into the showroom to learn more about Klingelnberg’s latest machine tool technology.
