FIELD: mechanical engineering.
SUBSTANCE: gearing leverage comprises driving crank (1) and driven crank (2) pivotally interconnected at one point of the unmovable base (3) and pivotally connected with the base through connecting rod (4) and additional connecting rod (5). Two same gear wheels (6) and (7), which are cooperate with each other through pinion (8), are pivotally connected with the ends of driving crank (1). Gear wheel (6) is connected with unmovable base (3) for permitting rotation and locking. Gear wheel (7) is made in block with main connecting rod (4). Additional connecting rod (5) is connected with driven crank (2) and main connecting rod (4) through flexible members (10) and (11) connected from different sides to additional connecting rod (5).
EFFECT: expanded functional capabilities.
