6 FAQs about [Wind turbine generator main shaft seal]

How does a wind turbine seal work?

A revolutionary wind turbine seal design that redefines rotary seals. System Seals has created a corkscrew-style seal that uses the turning action of a rotary shaft to pump escaping grease back inside the bearing where it belongs. During deflections, when grease naturally migrates towards the seal, the Vortex pumps it back inside.

How to lubricate a wind turbine shaft?

Grease as a lubricant has become standard in wind turbines. The main challenge is always to keep the media inside the bearing. Traditional shaft seals with a garter spring reach their functional limit with larger diameters. The radial force component of the spring that is relevant for the lip force towards the shaft gradually turns to zero.

Do XXL wind turbines need TRA-ditional seals?

Operators of large size wind turbines appreciate reliability and leakage-free performance. Based on our findings, tra-ditional sealing solutions for XXL dimensions do not fulfill these needs. This also comprises standard finger spring type of seals with their enormous range of preload at large shaft deflection.

Why should you choose Trelleborg sealing solutions for wind turbines?

Seals for wind turbines need to provide low friction, long life, zero leakage and easy installation, with maximized meantime between maintenance being a key requirement. Trelleborg Sealing Solutions contributes to effective operation of hydraulics, our products withstand rigors on land and offshore installations.

How long does it take to seal a turbine shaft?

They are well suited for sealing large-diameter bearings on pitch and yaw mechanisms. Main shafts: An on-site joined seal concept is said to replace a typical turbine main-shaft seal in less than 30 min and without major disassembly.

What is a vortex wind turbine seal?

The Vortex wind turbine seal was a stroke of genius that caused a global wind turbine manufacturer to retrofit all of its labyrinth seals with the new design. System Seals spent more than a year refining the design and testing prototypes, installation methods and tooling – both in the lab and in the field.
