Urelast Application In Wind Turbines

Gearbox mountings

Torque arm gearboxes with elastomer body made of EFFBE Urelast®.

• Longer service life in comparison to an unbonded spring

• Wearing of springs is minimised

• Optimised spring stiffness in comparison to rubber/metal-coated spring

• Improved vibration reduction in environment of torque arm gearbox

Azimuth system

Bonded spring assembly made of EFFBE Urelast® which is designed to avoid the loss of the braking effect of the claw bars in the azimuth system.

• Unbreakable - Elastomer compression springs retain force, an absolute loss of force is not possible

• Free of wear

• Flatter spring characteristic

• Larger permissible load range in comparison to plate springs, for same installation space

• Preload force adjustable by varying rotation angle

• Avoidance of total failure of azimuth drives

• Same installation space/connection dimensions

Generator mountings and mounting elements for all applications

Custom-developed mounting elements for generator mountings and standard mounting elements from the Levelmount series.

• Source and receiver insulation

• Vibration insulation

• Structure-borne noise insulation

• Shock absorption

Elastomer compression springs

Elastomer compression springs made of EFFBE Urelast® with a wide range of qualities and hardnesses, specifically designed for the given application.

• Very long service life

• Defined spring properties

• Bonded, unbonded

• Customised component parts, any design geometry possible
