DYNAMIC JOINT FOR TRANSMISSION OF ROTARY MOTION BETWEEN TWO SHAFTS Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: joint comprises a driven hub connected coaxially with one shaft 20 and engages vibratingly a plurality of planetary transmission members 2, equispaced around the axis of said hub. Planetary transmission members 25 are arranged between driven plate-like wheel 21 which is secured coaxially to second shaft 23 and intermediate plate-like wheel 24 linked vibratingly with driven plate-like wheel 21 and interact therewith. Planetary transmission members 25 rotated by hub 18 are guided by driven and intermediate plate-like wheels 21 and 24 over an elliptic path which sets them into cyclic reciprocating motion with relation to the axis of driven hub 18. Driving mechanism 25 tends to rotate driven and intermediate plate-like wheels 21 and 24 in opposite directions for transmitting the resultant forces which equalize the force received from hub 18, to planetary transmission members 25. EFFECT: improved design. 16 cl, 10 dwg
