Grashof linkage definition

WebDrag-link Four-bar Mechanism. The drag-link refers to a four-bar linkage in which both rotating links (cranks) make complete revolutions. As long as you keep the points that control the lengths of the links within the rectangle and approximately the same length, there will be no dead-point positions and both cranks will turn freely. WebApr 16, 2024 · Grashof's law is a simple rule that allows designing a mechanism in which full rotation is required, either because a motor will be connected or, on the contrary, because you want to transform an oscillatory motion into a rotary one, in such a way that it is mathematical and physically viable.
