Abstract:
A pitch governing mounting assembly for securing a windmill blade to a windmill input shaft and reducing a pitch of said blade in response to an increase in a rotational speed of said drive shaft, said assembly comprising:a first member connectable to said input shaft; a second member connectable to an inner end of said blade and slidably received by said first member for relative axial movement between said first and second members, along a governor axis generally aligned with a blade axis of said blade, between a first position and a second position; a rotator acting between said first member and said second member to cause rotation of said second member relative to said first member about said governor axis to reduce said pitch of said blade in response to said relative axial movement from said first position toward said second position; and, biasing means acting between said first and second members to urge said assembly toward said first position, said biasing means being a stack of Belleville washers.
