CHEBYSHEV FOUR-BAR APPROXIMATE CIRCLE-TRACING MECHANISM
Click to enlargeClick to enlarge Description

The lengths of the links of four-bar linkage ABCD comply with the conditions: B͞C=D͞C=C͞M=2.94A͞B, A͞D=2.83A͞B and angle β=124°. When link 1 turns about fixed axis A, point M of link 2 describes a path of which a certain portion approximates a circular arc.
