FIELD: machine building.
SUBSTANCE: link mechanism consists of link mounted on base, swinging on axis and connected with output link, and of control device. A movable stone with a tooth element is installed in a slot of the link. The control device corresponds to two worms with crossing and mutually perpendicular axes and worm wheel. The worm wheel is rigidly fixed on axle of the worm interacting with the tooth element and is conjugated with another worm, the axle of which is matched with swinging axle of the link. Notably, the stone is also coupled with the output link of the mechanism.
EFFECT: reduced wear of link and reduced noise during mechanism operation.
