Document Type and Number:
Japanese Patent JPS5914395
Kind Code:
B2
Abstract:
A variable-pitch propeller has a hollow hub rotatable about a hub axis and carrying a plurality of angularly equispaced vanes each rotatable on the hub about a respective vane axis extending radially of the hub axis. Each of the vanes has an eccentric pivot pin parallel to its respective vane axis and connected via a bearing to one end of an arm formed on an adjustment member displaceable in the hub along the hub axis and rotatable in the hub about the hub axis. The bearing allows for rotation of the pivot pin relative to the arm in which it is received and for displacement of the pivot pin along the pivot axis relative to the arm receiving it. Thus axial displacement of the adjustment member will force the pivot pins to orbit limitedly about the respective vane axes with concomitant sliding of the bearing along the pin and simultaneous rotation of the adjustment member in the hub.
