The method for determining the number of sections of the crank lever mechanisms con-rod curve approaching with stop of the output link and the length includes finding by curvature of certain sections on the con-rod curve approaching the circle (sphere). For the spatial lever mechanisms, in addition to the curvature, further torsion of the curve is defined. To determine the number and lengths of approach sections, the tangent lines to the sphere at all points of the curve are found, and as a result, the characteristic points (peaks) in which the radii of the spheres are maximal are obtained. |
