Problem

Mechanical breakdown of the torque support and gearbox bearing are often due to excessive load, caused by the high spring stiffness in conventional rubber-metal springs.

Solution for the 4-Point-Gearbox Mounting in Wind Power Stations

Reducing the spring stiffness and therefore increasing of the spring deflection by conditioned and bound Urelast springs. The binding is achieved by an additional metal spring plate or a carbon cover on both sides of the Urelast spring.

Advantages of Bounded Urelast Springs

• Longer lifetime compared to an unbound spring
• Minimized wear of the spring
• Less spring stiffness results in 1.5 ? 2 times higher spring deflection compared to rubber-metal springs
• Higher rate of vibration isolation
