German manufacturer KTR has extended its product range for wind turbines with recent yaw brakes. The KTR-Stop Yaw brake makes sure that the nacelle is held in a required direction. It differs from a rotor brake in that the azimuth system is always active. When the nacelle turns, the Yaw brake is controlled so it…
Brakes for pitch and yaw
The requirements for pitch and yaw brakes include high reliability, long maintenance cycles, resistance to environmental influences, and a tight braking-torque tolerance. For pitch drives, one brake manufacturer has developed spring loaded devices as holding brakes that have to perform in a particular way in emergencies, even after a failure. The brake casing is encapsulated.…
Yaw brakes for wind turbines
A full array of caliper designs is available from Twiflex, Ltd. to meet the yaw braking-force requirements of any size wind turbine. All brake models are durable, hydraulically activated, and direct applied. Models T20 and T40 deliver up to 40 kN braking force, feature two-bolt side mounting, and are intended for light to medium-duty applications.…
New, longer lasting brake pads for wind turbine
Tribco Inc. will exhibit brake pads that last 3 to 5 times longer than conventional brake pads—but won’t scratch or wear down brake rotors—because they are lined with Braketex, the world’s first and only 100% Kevlar fibered composite friction lining. Braketex is also virtually dust free whereas conventional linings generate dirty, abrasive black dust that…
Brakes for pitch and yaw drives
Emergency braking requirements of today’s large wind turbines under maximum wind conditions are comparable to those of a 40-ton mining truck driving down a 25% grade at 87 mph with a cliff just ahead. To meet these demanding requirements, Warner Electric , South Beloit, Wisc., an Altra Industrial Motion company, modified its ERS series of…
