Wind-power rotor-blade suspension system - has lemniscate links in spherical rubber-and-metal bearings

摘要

The rotor-blade-suspension system (1-8) for an axial-flow wind-power unit is guided by a lemniscate linkage. The links are fixed in spherical rubber-and-metal bearings, allowing flapping movement of the blade roots and requiring no maintenance. Blade adjustment on overspeeding can be initiated by torsion of the blade roots, and even adjustment of other blades can be effected by the cross-member. USE/ADVANTAGE - Simple construction of rotor blade suspension for axial-flow wind-power unit.
