Teeter mechanism for a multiple-bladed wind turbine

摘要

A teeter mechanism (40) for a multiple-bladed wind turbine includes a rotor shaft (42) operable to rotate about a first axis (44). A spherical member (46) is rotatable about the first axis along with the rotor shaft. A plurality of turbine blades (50) is mounted to a rotor hub (48). The rotor hub rotationally drives the rotor shaft (42), and is operable to teeter about the spherical member (46) such that the rotor hub (48) rotates about the first axis (44) in a first position and rotates about a second axis (52) offset from the first axis in a second, teeter position.
