Simple Machines Assembly
A SIMPLE MACHINE is a mechanical device that changes the direction or magnitude of a force. SIMPLE MACHINES can be defined as the simplest mechanisms that provide mechanical advantage. In other words, simple machines are devices with few or no moving parts that make work easier. Mechanical advantage is an advantage gained by using simple machines to accomplish work with less effort. The goal is to make the task easier (which means it requires less force), but this may necessitate more time or room to work (more distance, rope, etc.). An example of this is, applying a smaller force over a longer distance to achieve the same effect as applying a large force over a small distance. Mathematically speaking mechanical advantage is the ratio of the output force exerted by a simple machine to the input force applied to it. Simple machines have been around for a very long time. Using simple machines, Egyptians built the Great Pyramids thousands of years ago. Simple machines will always be around in more advanced forms as building blocks of compound machines and other complex machinery.
Simple machines we supply our clients can be broadly categorized as:
- Lever, Lever Assembly
- Wheel and axle assemblies
- Pulley & Hoist, Pulley Systems
- Inclined plane
- Wedge and wedge based systems
- Screw and screw systems
A simple machine is an elementary device that has a specific movement (often called a mechanism), which can be combined with other devices and movements to form a machine. Thus simple machines are considered to be the ''building blocks'' of more complicated machines. As an example, a lawn mover may incorporate six simple machines. We do use visual simulation tools in the design of some simple machines, which aids in the optimization process.
To give you a more familiar example, a bicycle may have the following simple machines:
Levers: Shifters, the pedal levers, derailleurs, handlebars, freewheel assembly, brakes.
Wheel and axle: The wheels, pedals, crankset
Pulleys: Parts of the shifting and braking mechanisms, drive train (chain and gears).
Screws: Many of these hold parts together
Wedges: The teeth on the gears. Some gooseneck assemblies where the handlebars attach to the front fork tube may employ a wedge to tighten the connection.
A COMPOUND MACHINE is a device that combines two or more simple machines. Using the six basic simple machines, various compound machines can be assembled. There are many simple and compound machines in our homes. Some examples of the compound machines used at home are can openers (wedge and lever), exercise machines/cranes/tow trucks (levers and pulleys), wheel barrow (wheel and axle and lever). As an example, a wheelbarrow combines the use of a wheel and axle with a lever. Car jacks are examples of screw-type simple machines that enable one person to lift up the side of a car.
Many of the machine elements we manufacture and supply our customers are used in the assembly of simple machines. The choice of materials, coatings and fabrication processes are very important and depends on the application of the simple machine being designed for a particular task. We will always be pleased to guide you in the design phases of your simple machines and manufacture them for you with the highest quality. Simple machines AGS-TECH Inc. has manufactured are being used in automobiles, motorcycles, auto lift equipment, conveyor systems, production equipment and machines, consumer electronics and goods.
