PLANET-LEVER MECHANISM Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: kinematical connection between gear 6 and stand 1 is constructed as two pivoting parallelograms 10,12 interconnected with connecting rods 11 having triangle form. One ends of pivoting parallelogram 10 are pivotally coupled with the first and second tops of connecting rod 11. The other ends are pivotally connected with flat 9. One ends of cranks of pivoting parallelograms 12 are pivotally coupled with the first and third tops of connecting rod 11. The other ends are pivotally connected with stand 1. When driving shaft 2 rotates, pin 4 of crank 3 sets gear 6 in rotation owing to its kinematical connection with stand 1. Rotation is transmitted from gear 6 to driven shaft 8 through a wheel with inner teeth 7. EFFECT: improved design. 1 dwg
