Abstract
A variable diameter belt type power transfer assembly having a drive sheave and a driven sheave, both of which are adjustable and include a pair of opposing coaxial flanges, one of which is axially movable relative to the other, is disclosed wherein both flanges of the drive sheave are provided with first and second belt engaging surfaces flaring radially outwardly with respect to each other so as to define first and second variable diameter belt receiving grooves therebetween. A dual range of velocity ratios between the drive sheave and the driven sheave is obtainable by selectively positioning a drive belt in the respective variable diameter belt receiving grooves. The inner and outer flange portions of one sheave member are constructed to allow the outer sheave portion to be selectively located in an operative position and an axially spaced retracted position relative to the inner sheave portion.
