Seat Belt
A seat belt (also known as a safety belt, or spelled seatbelt) is a vehicle safety device designed to secure the driver or a passenger of a vehicle against harmful movement that may result during a collision or a sudden stop. A seat belt reduces the likelihood of death or serious injury in a traffic collision by reducing the force of secondary impacts with interior strike hazards, by keeping occupants positioned correctly for maximum effectiveness of the airbag (if equipped), and by preventing occupants being ejected from the vehicle in a crash or if the vehicle rolls over. When in motion, the driver and passengers are traveling at the same speed as the vehicle. If the vehicle suddenly stops or crashes, the occupants continue at the same speed the vehicle was going before it stopped. A seatbelt applies an opposing force to the driver and passengers to prevent them from falling out or making contact with the interior of the car (especially preventing contact with, or going t ...

Belt (mechanical)
A belt is a loop of flexible material used to link two or more rotating Drive shaft, shafts mechanically, most often parallel. Belts may be used as a source of motion, to Transmission (mechanics), transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the driver if on parallel shafts). The belt drive can also be used to change the speed of rotation, either up or down, by using different sized pulleys. As a source of motion, a conveyor belt is one application where the belt is adapted to carry a load continuously between two points. History The mechanical belt drive, using a pulley machine, was first mentioned in the text the ''Dictionary of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conveyor Belt
A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types of conveyor systems. A belt conveyor system consists of two or more pulleys (sometimes referred to as drums), with a closed loop of carrying medium—the conveyor belt—that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the unpowered pulley is called the idler pulley. There are two main industrial classes of belt conveyors; Those in general material handling such as those moving boxes along inside a factory and bulk material handling such as those used to transport large volumes of resources and agricultural materials, such as grain, salt, coal, ore, sand, overburden and more. Overview Conveyors are durable and reliable components used in automated distribution and warehousing, as well as manufacturing and produ ...

Belt (clothing)
A belt is a flexible band or strap, typically made of leather, plastic, or heavy cloth, worn around the natural waist or near it (as far down as the hips). The ends of a belt are free; and a buckle forms the belt into a loop by securing one end to another part of the belt, at or near the other end. Often, the resulting loop is smaller than the hips. Belts come in many lengths because of the variety in waist sizes, and most belts can be adjusted at the buckle to suit the wearer's waist. Description Belts are used variously to secure or hold up clothing, such as trousers, shorts, and skirts; to carry objects, such as tools and weapons; and to define or accentuate the waist. Some garments have a series of belt loops at the waist, through which a belt can be threaded. Additionally, many belts have a "keeper loop" affixed to one end, near the buckle. The keeper loop stops the free end of the belt from flapping around once the belt is buckled. Some belts also have an end tip (ma ...

Greenstone Belt
Greenstone belts are zones of variably metamorphosed mafic to ultramafic volcanic sequences with associated sedimentary rocks that occur within Archaean and Proterozoic cratons between granite and gneiss bodies. The name comes from the green hue imparted by the colour of the metamorphic minerals within the mafic rocks: the typical green minerals are chlorite, actinolite, and other green amphiboles. Greenstone belts also often contain ore deposits of gold, silver, copper, zinc and lead. A greenstone belt is typically several dozens to several thousand kilometres long. Typically, a greenstone belt within the greater volume of otherwise homogeneous granite-gneiss within a craton contains a significantly larger degree of heterogeneity and complications and forms a tectonic marker far more distinct than the much more voluminous and homogeneous granites. Additionally, a greenstone belt contains far more information on tectonic and metamorphic events, deformations, and paleogeologic ...

Timing Belt (camshaft)
In a piston engine, either a timing belt (also called a ''cambelt'') or timing chain or set of timing gears is used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's valves open and close at the correct times in relation to the position of the pistons. Design In most piston engines, the camshaft(s) are mechanically connected to the crankshaft. The crankshaft drives the camshaft (via a timing belt, timing chain or pushrods), which in turn actuates the intake and exhaust valves. These valves allow the engine to inhale air (or an air/fuel mixture) and exhale the exhaust gasses. The most common devices to transfer the drive are toothed rubber belts, metal timing chains or a set of gears. The teeth of the belt/chain/gears mesh with both the crankshaft and camshaft(s), thereby synchronising their motion. In many older overhead valve engines, the camshaft is located in the block near the crankshaft, therefore a simple gear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Belt-fed systems minimize the proportional weight of the ammunition apparatus to the entire weapon system, and allow high rates of continuous fire without needing frequent magazine changes. The capacity of belts and associated belt containers is typically a function of weight and bulk, and their size is limited by caliber and the combined portability of the weapon and ammunition. The most common ammo capacity typically carried on a man-portable weapon system vary from 50 to 300 rounds. Variants Feed strip 8mm Lebel feed strip on an M191 ...

Red Belt (martial Arts)
A red belt is one of several colored belts used in some martial arts to either denote rank or differentiate opponents in a competition. Like the more commonly known black belt, its use varies between arts, with most using it for the style founder, grandmaster or other high rank, while others use it as the immediately pre–black belt rank or even to denote a beginner who holds no rank. In some schools, especially those with lineage related to Kodokan Judo, a red belt signifies ninth or tenth degree Dan rank, the highest ranks attainable. In martial arts *In karate, even though grandmasters and non–black belts may both wear a "red belt", the Dan rank belts are broader: kyu (pre–black belt) rank belts normally having a width of 4 centimeters and dan rank belts having a width of 5 centimeters. Also, the grandmaster's red belt is usually darker in color and embroidered with the grandmaster's name and style as customary for dan rank belts. * In Brazilian Jiu-Jitsu, the 7th de ...

Serpentine Belt
A serpentine belt (or drive belt) is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, air conditioning compressor, air pump, etc. The belt may also be guided by an idler pulley and/or a belt tensioner (which may be spring-loaded, hydraulic, or manual). To allow the belt to pass over more than three pulleys with a large enough wrap angle to avoid slipping, idler pulleys which press against the back of the belt are included, forcing the belt into a serpentine shape. To accommodate this bidirectional flexing while remaining strong enough to transfer the total force required by multiple loads, a serpentine belt is almost always of multi-groove (multi-vee, poly-v, or multi-rib) construction. Variations On some engine designs, the "back" (smooth side) of the belt may drive some accessories. This is typically limited to components requiring less torque or where a large angle of wrap i ...

Black Belt (martial Arts)
In East Asian martial arts, the black belt is associated with expertise, but may indicate only competence, depending on the martial art. The use of colored belts is a relatively recent invention dating from the 1880s. Origin The systematic use of belt colour to denote rank was first used in Japan by Jigoro Kano, the founder of judo in the 1880s. Previously, Japanese Koryu instructors tended to provide rank certificates only. Initially the wide obi was used. As practitioners trained in a kimono, only white and black obi were used. This kind of ranking is less common in arts that do not claim a far Eastern origin, though it is used in the Marine Corps Martial Arts Program. Relative rank Rank and belts are not equivalent between arts, styles, or even within some organisations. In some arts, a black belt may be awarded in three years or even less, while in others it takes dedicated training of ten years or more. Testing for black belt is commonly more rigorous and more centrali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Championship Belt
A championship belt is a large, extravagantly designed belt used primarily in combat sports such as boxing, mixed martial arts, and professional wrestling to signify the champions of the promotion or company, much like a cup or trophy in other sports. There are several companies in the business of constructing championship belts. Early history The first belt given as a prize for accomplishments within the ring was presented in 1810 by King George III to bare-knuckle boxer Tom Cribb, after he defeated Tom Molineaux, an American former slave. Boxing In boxing, the individual organizations such as the World Boxing Council, the World Boxing Association, the International Boxing Federation, and the World Boxing Organization each have their own unique championship belt that are awarded to the champions of each weight class. Boxers strive to win the belt of all four organizations to unify their weight divisions. '' The Ring'' also created a championship system that is "intended to re ...
