Chapter 2: A THESAURUS OF MECHANISMS

Figure 2.1: Snap-action mechanisms. These mechanisms are bistable elements in machines. They are used in switches to quickly make and break electric circuits and for fastening items. ( a) Snap-action toggle switch; ( b) to ( h) seven variations of snap-action switches; ( i) circuit breaker; ( j) to ( o), spring clips.
Figure 2.2: Linear actuators. These are devices that cause a straight-line displacement between two machine elements. ( a) Lead screw; ( b) worm gear with stationary nut; ( c) worm gear with stationary screw; ( d) single-acting hydraulic cylinder; ( e) double-acting hydraulic cylinder; ( f) telescoping hydraulic cylinder; ( g) hydraulic cylinder with positional feedback; ( h) hydraulic cylinder with floating link feedback.
Figure 2.3: Fine adjustments I. Fine adjustments for stationary mechanisms are mechanisms that make a small change in the position of a mechanical member. ( a), ( b) Screw adjustments; ( c), ( d) differential screws; ( e) Chinese windlass; ( f) differential hoist; ( g) worm gear and screw; ( h) worm gears in series; ( i) lever; ( j) levers in series; ( k) toggle mechanism; ( l) screws to adjust angular position; ( m), ( n) eccentric cranks; ( o) wedges; ( p) harmonic drive.
