ABSTRACT:
A drive pulley mechanism for an engine for driving auxiliary equipment by V-belts at two different speed ratios relative to engine speed wherein an epicyclic gear train of a ring gear, multiple planet gears and a sun gear is employed for the low speed-change drive as established by a centrifugal clutch functioning at engine speeds above a predetermined level to release the direct one-to-one drive. An Oldham coupling connects the sun gear to the input drive member for causing a uniform distribution of driving loads through the multiple planet gears to the ring gear.
