FB73520140 Vestas Springs, Vestas (114151)

Suitable for Vestas: V66RCC, V66VCS, V80 2MW, V90 1.8MW, V90 2MW | Demand per turbine: 8 units Problem: Mechanical breakdown of the torque support and the 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
