<p>INVENTOR PETER AFTON GALBRAITH TITLE INFINITELY VARIABLE SPEED DRIVE MECHANISM An infinitely variable drive mechanism comprising a pair of sun gears mounted on a first shaft for rotation therewith and at least one of said discs being capable of limited axial movement along the shaft and being loaded towards each other, a plurality of planet discs each rotatably mounted on one end of a corresponding arm or fork for rotation about an axis substantially parallel to said first shaft, the other end of each arm or fork being pivotally mounted on a carrier member for movement about an axis substantially parallel to the first shaft, said planet discs moving in a plane normal to the axis of rotation, said carrier being mounted on a second shaft for rotation therewith about an axis coaxial with the axis of rotation of said first shaft, a pair of spaced non-rotating annular members substantially coplanar with and concentric with said sun discs, the inner periphery of said annular members and the outer periphery of said sun discs embracing and frictionally engaging said planet discs and means for varying the radial position of said planet discs with respect to said annular members and sun discs and this variable drive mechanism having one of the shafts attached to a conventional single stage epicyclic gear train.</p> |
