DOUBLE FLOW GEARING Russian patent published in 1996 - IPC

FIELD: mechanical engineering; gear trains to drive vehicle wheels. SUBSTANCE: gearing has driving hear wheel 5 to transmit torque to driven gear wheel through two idler wheels. To level up efforts gear wheel 5 is installed on bearings 6 and 7 in shackles 8 and 9 hinge-secured on pin of idler gear wheel. Plane passing through axis of driven gear wheel and axis of pin carrying the shackles is turned, relative to plane in which axes of driving gear wheel 5 and driven gear wheel are located, to side opposite to direction of rotation of driven gear wheel at forward running. Angle between plane in which axes of gear wheels are located and plane of arrangement of axes of idler gear wheel and gear wheel 5 is equal to or is close to pressure angle of driving and driven gear wheels. EFFECT: enlarged operating capabilities. 5 dwg
