PURPOSE:To provide a supporter for a windmill speed-increaser where noise of the windmill speed-increaser can be prevented from solid-propagating to a nacelle and a tower. CONSTITUTION:Support tables 1.3 are arranged at equal pitches at the circumferential edge of a flange 3.1 fixed to the outer peripheral portion of a speed- increaser 3. A support portion 1.5 constituting the support table 1.3 is covered with an elastic body 1.1. A nacelle side support table 1.2 is disposed on a side wall at the tip of a nacelle 4 in a manner facing to the flange fixed to the support table. The support portion 1.5 covering the elastic body 1.1 is fitted to a cylindrical hole formed on the nacelle side support table 1.2 so that the speed-increaser 3 is fixed to the nacelle 4. Consequently, it is possible to inhibit vibration and noise generated in the speed-increaser 3 from solid-propagating to a tower 7 via the nacelle 4, thus remarkably reducing noise of a windmill. Furthermore, adjustment of rigidity of the elastic body 1.1 can realize control of noise generating quantity, and effectively inhibit noise generation of specific frequency. |
