Study Notes
Mechanisms in Design and Technology
Mechanisms are used to create movement, change shape, or perform specific functions in products. They can be classified into three main categories:
Types of Mechanisms
- Linkages: Connect two or more components to create movement or rotation.
- Examples: hinges, pivots, and lever systems
- Cams and Followers: Convert rotary motion into linear motion.
- Examples: door handles, gear systems, and printing press mechanisms
- Gears and Transmissions: Change speed, direction, or torque of rotational motion.
- Examples: gearboxes, bicycle gears, and clockwork mechanisms
Key Components of Mechanisms
- Axles: Rotating shafts that support rotating components.
- Bearings: Reduce friction and wear between moving parts.
- Fasteners: Hold components together, such as screws, nuts, and bolts.
- Springs: Store energy and provide resistance to motion.
Mechanism Design Considerations
- Kinematics: Study of the motion of objects without considering forces.
- Dynamics: Study of the motion of objects considering forces and energy.
- Material selection: Choose materials that can withstand stresses, loads, and environmental conditions.
- Manufacturing processes: Consider the feasibility and cost of manufacturing the mechanism.
Applications of Mechanisms
- Robotics: Use mechanisms to create movement and perform tasks.
- Automotive systems: Use mechanisms to transmit power, change direction, and provide movement.
- Medical devices: Use mechanisms to create movement, change shape, or perform specific functions.
- Consumer products: Use mechanisms to create movement, change shape, or perform specific functions in everyday products.
