CHEBYSHEV FOUR-BAR APPROXIMATE STRAIGHT-LINE MECHANISM

Click to enlargeClick to enlarge Description

The lengths of the links of four-bar linkage ABCD comply with the conditions: B͞C=D͞C=C͞E=2.17A͞B and A͞D=2.83A͞B. When link 1 rotates about fixed axis A, point E of link 2 describes path q-q. Upon motion of point B along arc a-b-c, point E travels along portions a₁-b₁ and b₁-c₁ which approximate two mutually perpendicular straight lines p-p and t-t.
