Grashof linkage definition
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. Borderline cases WebJan 3, 2024 · Grashoff's condition: Grashoff 4-bar linkage: A linkage that contains one or more links capable of undergoing a full rotation. A linkage is Grashoff if: where: S = shortest link length, L = longest, P, Q = intermediate length links Non Grashoff 4 bar: No link can rotate 360 if: S + L > P + Q In Grashof’s linkage at least one link will be ...

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.
