The following is a list of example mechanical components and safety considerations. This is not an exhaustive list but can be a good jump start to brainstorm ideas.
Levers and Linkages: These components utilize the principle of leverage to amplify or redirect forces. They consist of rigid bars or arms connected by joints or pivots.
- Ensure that levers and linkages are securely fastened and do not have any loose or weak connections.
- Avoid placing fingers or other body parts near the moving parts of levers and linkages during operation.
- Consider the mechanical advantage and forces involved to prevent overloading or sudden release of energy that could cause injury.
Gears and Pulleys: These components transmit rotational motion and torque between shafts or change the speed and direction of rotation. Gears have interlocking teeth, while pulleys have grooves for belts or cables.
- Use appropriate guards or enclosures to prevent accidental contact with moving gears and pulleys.
- Ensure proper alignment and engagement of gears to prevent binding or jamming.
- Regularly inspect gears and pulleys for signs of wear, damage, or misalignment.
- Avoid using gears or pulleys with sharp edges or protrusions that could cause injury.
Springs: These components store mechanical energy when compressed, stretched, or twisted and release it when the applied force is removed or reduced.
- Be cautious when handling springs to prevent accidental release of stored energy. Use proper tools or techniques for compression or tensioning.
- Ensure that springs are correctly sized and rated for the intended application to avoid exceeding their elastic limits or causing sudden failures.
- Use appropriate safety measures, such as containment or shielding, if dealing with high-tension springs that could pose a risk of injury upon release.
Cam and Follower: A cam is a specially shaped rotating or sliding element, while a follower is a mechanism that tracks the shape of the cam to convert its motion into linear or rotational motion.
- Ensure proper alignment and smooth operation of the cam and follower system.
- Avoid sharp edges or protrusions on cams or followers that could cause injury.
- Lubricate the cam and follower mechanism as necessary to reduce friction.
- Provide suitable guards or covers to prevent accidental contact with moving parts.
