Structural Synthesis on Speed Multipliers with Fixed Axle Gear Used in Wind Turbine

Abstract

Speed multipliers used in wind turbine may be considered as atypical constructive structural solutions, as compared to other gear transmissions, due to the following reasons: the load on the speed multiplier is variable and its value increases due to vibrations that will occur during operation; the torque has a high value and low speed at the entrance in the speed multiplier; the multipliers structure must be both small-sized and lightweight. With these requirements in view, this article presents several constructive solutions for speed multipliers with fixed axle gear.
