WHEEL AND AXLE
a wheel or spoke is locked to a central axle so that when one is turned
the other must turn. A longer motion at the edge of the wheel is
converted to a shorter more powerful motion at the axle. In reverse, a
short powerful force at the axle will move the wheel's edge a greater
distance PULLEY SYSTEM a single pulley simply reverses the direction of a force. When two or more pulleys are connected together, they permit a heavy load to be lifted with less force. The trade-off is that the end of the rope must move a greater distance than the load. WEDGE a wedge converts motion in one direction into a splitting motion that acts at right angles to the blade. Nearly all cutting machines use the wedge. A lifting machine may use a wedge to get under a load SCREW a screw is a central core with a thread or groove wrapped around it to form a helix. While turning, a screw converts a rotary motion into a forward or backward motion LEVER a lever is a stiff rod that rotates around a pivot point. Downward motion at one end results in upward motion at the other end. Depending on where the pivot point is located, a lever can multiply either the force applied or the distance over which the force is applied. |

MACHINERY ELEMENTS AND INDUSTRIAL DEVICES GEARS, BEVEL GEARS, WORM GEAR, RACK AND PINION |
|||
|
GEARS
are toothed or pegged wheels meshed together to transmit
motion and force. In any pair of gears the larger one will
rotate more slowly than the smaller one, but will rotate
with greater force. Each gear in a series reverses the
direction of rotation of the previous gear BEVEL GEARS gears that mesh at an angle change the direction of rotation WORM GEAR is a combination of a gear meshed with the threads of a screw. This combination changes the direction of turning motion by ninety degrees. Worm gears also decrease the speed of turning from screw to gear and increase its force RACK AND PINION a single gear, the pinion, meshes with a sliding toothed rack. This combination converts rotary motion to back and forth motion. Windshield wipers in cars are powered by a rack and pinion mechanism. A small pinion at the base of the wiper meshes with a sliding rack below. |

MACHINERY ELEMENTS AND INDUSTRIAL DEVICES CAM, CRANK AND ROD, CHAIN AND BELTS, RACHET |
|
CAM
is a wheel with shaped bumps on it. Cams are often connected to rods,
levers, or springs. In the gravity trip hammer shown here, the bumps on
the turning cam push down on the end of the lever making it raise the
hammer again and again CRANK AND ROD the crank is a wheel with a pivoting arm attached near its edge. The arm is attached by a hinge to a rod. When the crank turns, the rod is pushed back and forth. Alternatively, if the rod is pushed back and forth at the right speed, the crank will turn. The crank and rod shown here are part of giant steam engine CHAIN AND BELTS a chain or belt connects two separated wheels so that one turns, the other will turn in the same direction RACHET is a device that allows a wheel to turn in only one direction. The ratchet wheel has specially shaped teeth. A bar on a pivot called the "pawl" is fixed above the ratchet wheel. The pawl slides over the teeth of the ratchet in one direction, but blocks the motion of the teeth if the wheel turns in the other direction |

AUSTRIAN INDUSTRIAL MACHINERY APPLICATIONS - MACHINES MANUFACTURING FOR CONVERSION OF ENERGY |
|||
|
INDUSTRIAL MACHINERY
APPLICATIONS Compressors and pumps, External combustion
engines (steam, stirling), Turbine (gas, stearm, jet, water, wind
generator, winmill..), Airfoil, Rockets, Computing machines , Automated
machines (Robots, Vending machines, automatic packaging machines,
automation industrial systems..) Biological machines, Construction
machines, Vehicle CONVERSION OF ENERGY As a consequence of energy conservation law, one form of energy can often be readily transformed into another - for instance, a battery converts chemical energy into electrical energy. Similarly, gravitational potential energy is converted into the kinetic energy of moving water (and a turbine) in a dam, which in turn is transformed into electric energy by a generator |

MINING INDUSTRY MACHINERY MANUFACTURING, WIND POWER TECHNOLOGY AND MACHINES SOLUTIONS |
||
|
MINING MACHINERY resembles that of other
heavy industries. Heavy machinery is needed in mining to
break and remove rocks of diverse hardness and toughness.
Bulldozers, drills, explosives and trucks are important
for digging into the land, especially in surface mining.
Underground mining, like continuous mining, tends to be
more technologically sophisticated because of the
dangers and expense of subsurface tunneling. Continuous
mining equipment manufacturers include Joy Mining
Machinery, Caterpillar, Komatsu, Volvo, Hitachi, Dynapac,
Terex, Dresser, TCM, Kawasaki, Furukawa, Elphinstone,
Poclain and Demag.
WIND POWER TECHNOLOGY AND MACHINES most modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator. In windmills (a much older technology) wind energy is used to turn mechanical machinery to do physical work, like crushing grain or pumping water. The power in the wind can be extracted by allowing it to blow past moving wings that exert torque on a rotor. The amount of power transferred is directly proportional to the density of the air, the area swept out by the rotor, and the cube of the wind speed |

AUSTRIA MACHINERY MANUFACTURING - INDUSTRIAL MACHINES TECHNOLOGY - MECHANICAL ADVANTAGE |
|||
|
MACHINERY machine is any mechanical or
organic device that transmits or modifies energy to perform
or assist in the performance of tasks. It normally requires
some energy source ("input") and accomplishes some sort of
work. People have used mechanisms and machines to amplify
their abilities, these devices decrease the amount of force
required to do a given amount of work, alter the direction
of the force, or transform one form of motion or energy into
another MECHANICAL ADVANTAGE of the machines is the ratio between the force it exerts on the load and the input force applied. This does not entirely describe the machine's performance, as force is required to overcome friction as well. The mechanical efficiency of a machine is the ratio of the actual mechanical advantage (AMA) to the ideal mechanical advantage (IMA) |
