Mechanisms
This section shows how some basic mechanisms work. These mechanisms can be used in a wide variety of mechanical devices to create desired motions:
- Watts Linkage - creates nearly straight line motion using pivot links
- Geneva Escapment Wheel - creates incremental rotatation
- Intermittant Motion device - creates a delay between moving back and forth
- Scotch Yoke - converts rotatary to linear motion
- Scott Russel - converts vertical linear motion to horizontal linear motion
- Rack and Pinion - converts linear motion to or from rotary motion
- Locking Hold-down - clamps items firmly against a work surface
- Ratchet Wheel - converts oscillating motion to intermittent rotary motion
- Overrun Clutch - allows a rotary motion to drive another rotary member in one direction only
- Universal Joint - transmits rotary motion between members at various relative angles
