Abstract: A blade pitch regulating hub (1) having a circular base (4) having a base gear (5) pivotally attached thereto. Blade stems (6) are placed equally apart from one another around the hub base. The blade stems have stem gears (7) that all engage the base gear so that all of the blade stems rotate at equal distances and in the same direction. The pitch of the blade stems and blades (8) are also controlled by the regulating means (2). A speed regulating gear (12) regulates the rotational power output from a wind driven power generator by using a telescoping housing (14) and conical gear (19) that extend and retract depending on wind speed. A guide means (20) ensures that a sliding gear assembly (26) always stays engaged with the conical gear as the diameter of the conical gear changes as it retracts and extends. An output gear assembly (28) engages the sliding gear assembly and transfers power from the sliding gear assembly to an output axle (29).
