MECHANISM FOR TRANSMISSION OF VARIABLE POWER LOADS Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: mechanism relates to devices used in mechanical systems intended for realization of power-intensive operations. Mechanism has following pivotally linked components: crank, connecting rod, rocker arm, and post. Rocker arm is made in the form of double-arm flat spring. Secured on free end of flat spring is working member in the form of hammer which is intended for interaction with object of forging. Lengths of links in mechanism meet following expression (1+λ₁)²= λ22

+λ23, where λ₁,λ₂,λ₃ - relative lengths of crank, connecting rod, and rocker arm. In accordance with such arrangement of mechanism, maximal value of transmission angle μ_max= 90^° is ensured within range of direct stroke. Aforesaid embodiment of mechanism enhances its operational efficiency in transmitting variable power loads which are increasing with subsequent reducing. EFFECT: higher efficiency. 1 cl, 2 dwg
