SYSTEM AND ASSEMBLY FOR POWER TRANSMISSION AND GENERATION IN A WIND TURBINE
First Claim
1. A power generation system for a wind turbine included in a nacelle, comprising:
- a transmission having an input axially aligned with an output, the input configured to receive rotary motion generated by a wind driven rotor head, the output located downwind of the input;
an electromagnetic apparatus having an input configured to be coupled to the transmission output, wherein the electromagnetic apparatus is a generator and the input of the generator is a rotor, and wherein the output shaft of the transmission is a sun gear in a planetary gear-train included in the transmission; and
a bearing configured to radially support both the transmission output and the electromagnetic apparatus input.

Abstract
Various power transmission and generation systems and assemblies are provided for a wind turbine. In one embodiment, a power generation system is provided including a transmission having an input axially aligned with an output, the input configured to receive rotary motion generated by a wind driven rotor head, the input located downwind of the output, an electromagnetic apparatus having an input configured to be coupled to the transmission output, and a bearing configured to radially support both the transmission output and the electromagnetic apparatus input. In this way, a common bearing may support both the transmission and electromagnetic apparatus, allowing for a more compact and efficient design while retaining service and repair capabilities.
