SUSPENSION APPARATUS OF STEP-UP GEAR FOR WIND TURBINE

摘要

PURPOSE: A suspension apparatus of step-up gear for a wind turbine is provided to protect a step-up gear and a wind turbine from impact torque like typhoon by allowing translational displacement due to torque. CONSTITUTION: A suspension apparatus of step-up gear for a wind turbine comprises a reaction plate(10), a vertical linkage(20), a first spherical joint(30), a torsion beam(40), a second spherical joint(50), and a bearing box(60). The reaction plate receives the torque by the operation of the step-up gear. The vertical linkage is connected to both ends of the reaction plate and receives load by rotation torque. The first spherical joint movably connects the reaction plate to the vertical linkage. The torsion beam is connected to the vertical linkage and receives the load of the rotational direction torque by the reaction plate.
