TOOTHED TORQUE VARIATOR Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: variator is used for continuous variation of transmission ratio between input and output links of mechanism. Pairs of bevel gears are installed on driving and driven shafts, respectively. Closed hinge chain with teeth is embraced by band so that hinged of chain are mounted for moving along band, and every even hinge is locked to prevent its displacement in direction perpendicular to band. With its teeth chain engages teeth of bevel gears. Chain teeth tale unique position in spaces of bevel gear teeth in which circumferential pitch of chain teeth corresponds to that of tooth spaces of bevel gears. Torque is transmitted from driving shaft to driven one through teeth and tightened branch of chain. EFFECT: higher efficiency. 4 dwg
