Intermittent motion mechanisms An intermittent-motion mechanism is a linkage which converts continuous motion into intermittent motion. These mechanisms are commonly used for indexing in machine tools. Geneva wheel mechanism Fig.1: Geneva wheel mechanism In the mechanism shown (Fig.1), link … Continued
STEERING MECHANISMS Hooke’s joint (Universal joints) Hooke’s joins is used to connect two nonparallel but intersecting shafts. In its basic shape, it has two U –shaped yokes ‘a’ and ‘b’ and a center block or cross-shaped piece, C. (fig.1.47(a)) The … Continued
STRAIGHT LINE MECHANISMS Straight line motion mechanisms Straight line motion mechanisms are mechanisms, having a point that moves along a straight line, or nearly along a straight line, without being guided by a plane surface. Condition for exact straight line … Continued
Kinematic Inversions of Four Bar Chain, Slider Crank and Double Slider Crank Mechanism KINEMATIC INVERSION Inversions of mechanism: A mechanism is one in which one of the links of a kinematic chain is fixed. Different mechanisms can be obtained by … Continued
