Abstract
A teeter mechanism for a multiple-bladed wind turbine includes a rotor shaft operable to rotate about a first axis. A spherical member is rotatable about the first axis along with the rotor shaft. A plurality of turbine blades is mounted to a rotor hub. The rotor hub rotationally drives the rotor shaft, and is operable to teeter about the spherical member such that the rotor hub rotates about the first axis in a first position and rotates about a second axis offset from the first axis in a second, teeter position.
