Abstract RU 2092729 C1

FIELD: mechanical engineering. SUBSTANCE: gear train includes cylindrical housing, at two variable-speed drives and ratio change mechanism. Each variable-speed drive includes two curvilinear friction envelopes whose concavities are directed towards each other and intermediate friction member engageable with them. Curvilinear friction envelopes of adjacent variable-speed drives are rigidly interconnected. Ratio change mechanism is made in form of double-arm levers, bushes, two sectional bow-shaped rods and longitudinal rods articulated with them. EFFECT: enhanced reliability. 14 dwg
