BALANCED ARTICULATED DRIVER COUPLING Russian patent published in 2003 - IPC

FIELD: railway transport. SUBSTANCE: invention relates to couplings used as transfer mechanisms in traction drives of diesel locomotives, electric locomotives and electric trains. Proposed device contains driving and driven flanges, each provided with three cantilever forks uniformly spaced over circumference. Forks are connected with some ends of six drives by means of hollow shafts and rubber-metal blocks. Outer ends of drivers are connected with six forks of three bell-cranks by means of similar shafts and rubber-metal blocks. Bell-cranks are interconnected for movement in center by means of antifriction bearings. Pins of hollow shafts of driving and driven flanges are connected in pairs with interference by means of three lightened tie-rod from cantilever side. EFFECT: increased tolerable rotation of balanced coupling without torsional vibrations in system. 2 dwg
