FIELD: mechanical engineering. SUBSTANCE: mechanism has two double-arm cranks interconnected through a synchronizer. The cranks are secured to parallel shafts. One of the shafts is connected to a drive. The arms of the cranks are pivotally interconnected via connecting rods provided with a longitudinal groove for rollers and rigidly secured to the driven link. When cranks rotate the rollers of the driven link engage the connecting rods alternately, move along the grooves up to the dead center, rotate in opposite direction, and disengage. As a result the driven link moves intermittently. EFFECT: simplified design. 3 cl, 4 dwg |
