Norton P10
The Norton P10 was a prototype motorcycle designed by AMC in the 1960s. It used a unit construction 800 cc DOHC parallel twin engine. The model suffered from oil leaks and severe vibration during testing and was never put into production. Following the collapse of AMC in 1966 and the subsequent takeover by Manganese Bronze Holdings to form Norton-Villiers, the prototype was used as a starting point of the Z26, which was intended as a replacement for the Norton Atlas. History Charles Udall had joined AMC as Engineering Director in 1961 from Velocette, where he had been involved in the design of the M-series engines and the LE. He started designing a new DOHC twin, initially as a 750 but soon increased to 800 cc. A prototype was built, using a shortened featherbed frame, which was extensively road-tested, included at the MIRA track at Lindley, near Nuneaton. The engine had bad vibration problems and development engineer Wally Wyatt tried rubber mounting the engine. During accele ...

Norton Motorcycle Company
The Norton Motorcycle Company (formerly Norton Motors, Ltd.) is a brand of motorcycles, originally based in Birmingham, England. For some years around 1990, the rights to use the name on motorcycles was owned by North American financiers. From 2008 to 2020, a line of motorcycles was produced under owner and chief executive Stuart Garner. Due to financial failure with large debts, in April 2020 administrators BDO agreed to sell certain aspects of Garner's business to Project 303 Bidco Limited, a new business established for the purpose with links to Indian motorcycle producer TVS Motor Company. The business was founded in 1898 as a manufacturer of "fittings and parts for the two-wheel trade".Holliday, Bob, ''Norton Story'', Patrick Stephens, 1972, p.11. By 1902 the company had begun manufacturing motorcycles with bought-in engines. In 1908 a Norton-built engine was added to the range. This began a long series of production of single and eventually twin-cylinder motorcycles, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velocette LE
The Velocette LE is a motorcycle made by Veloce Ltd from 1948 to 1971. The designation LE stood for "little engine". Used by over fifty British Police forces, the police riders became known as "Noddies" because they were required to nod to senior officers, and the LE was nicknamed "the Noddy Bike". Production ended in 1970 when the company ran into financial problems and went into voluntary liquidation. The Mk I LE Velocette's Director, Eugene Goodman, planned an innovative and radical design that would appeal to a new market that needed cheap, clean and reliable transport. Designers Charles Udall and Phil Irving developed the Velocette LE as a "conceived-as-a-whole" design, with engine, gearbox, drive shaft and bevel box in a single unit to do a specific job. The Velocette LE was launched at the British International Motor Show at Earls Court in 1948 as the "Motorcycle for Everyman". With a 149 cc four-stroke, side-valve, water-cooled, horizontally opposed twin-cyli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorcycles Powered By Straight-twin Engines
A motorcycle (motorbike, bike, or trike (if three-wheeled)) is a two or three-wheeled motor vehicle steered by a handlebar. Motorcycle design varies greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport (including racing), and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activity such as joining a motorcycle club and attending motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparably popular to cars as a method of transport. In 2021, approximately 58.6 million new motorcycles were sold around the world, fewer than the 66.7 million cars sold over the same period. In 2014, the three top motorcycle producers globally by volume were Honda (28%), Yamaha (17%) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Motorcycle Museum (UK)
The National Motorcycle Museum occupies an site in Bickenhill, Solihull, England and holds the world's largest collection of British motorcycles. In addition to over 850 motorcycles, which cover a century of motorcycle manufacture, the museum has conference facilities. It is located close to the junction of the A45 road, A45 and the M42 motorway, M42, close to Birmingham Airport. History The founder of the museum, construction entrepreneur and self-made millionaire Roy Richards, started collecting good examples of British motorcycles in the 1970s. The museum opened in 1984 with an initial collection of 350 machines. The museum was developed to include conference facilities in 1985.

Reed Valve
Reed valves are a type of check valve which restrict the flow of fluids to a single direction, opening and closing under changing pressure on each face. Modern versions often consist of flexible metal or composite materials (fiberglass or carbon fiber). Applications Traditional Reed valves, normally a leather flap covering a hole, are amongst the earliest form of automatic flow control for liquids and gases. They have been used for thousands of years in water pumps and for hundreds of years in bellows for high-temperature forges and musical instruments such as church organs and accordions. In nature, heart valves operate in a somewhat similar fashion. Pumps Reed valves are used in some reciprocating compressor designs, and in the pumping element of some musical instruments, large and small. Two-stroke engines Reed valves are commonly used in high-performance versions of the two-stroke engine, where they control the fuel-air mixture admitted to the cylinder. As the piston ri ...

Split Link
In the mathematical field of knot theory, a split link is a link that has a (topological) 2-sphere in its complement separating one or more link components from the others. A split link is said to be splittable, and a link that is not split is called a non-split link or not splittable. Whether a link is split or non-split corresponds to whether the link complement is reducible or irreducible as a 3-manifold. A link with an alternating diagram, i.e. an alternating link, will be non-split if and only if this diagram is connected. This is a result of the work of William Menasco William W. Menasco is a topologist and a professor at the University at Buffalo. He is best known for his work in knot theory. Biography Menasco received his B.A. from the University of California, Los Angeles in 1975, and his Ph.D. from the Univ ..... A split link has many connected, non-alternating link diagrams.

O Ring
An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface. The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons. Static applications of O-rings may include fluid or gas sealing applications in which: (1) the O-ring is compressed resulting in zero clearance, (2) the O-ring material is vulcanized solid such that it is impermeable to the fluid or gas, and (3) the O-ring material is resistant to degradation by the fluid or gas. The wide range of potential liquids and gases that need to be sealed has necessitated the development of a wide range of materials. O-rings are one of the most common seals used i ...

PTFE
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. It is one of the best-known and widely applied PFAS. The commonly known brand name of PTFE-based composition is Teflon by Chemours, a spin-off from DuPont, which originally discovered the compound in 1938. Polytetrafluoroethylene is a fluorocarbon solid, as it is a high-molecular-weight polymer consisting wholly of carbon and fluorine. PTFE is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons exhibit only small London dispersion forces due to the low electric polarizability of fluorine. PTFE has one of the lowest coefficients of friction of any solid. Polytetrafluoroethylene is used as a non-stick coating for pans and other cookware. It is non-reactive, partly because of the strength of carbon–fluorine bonds, so it is often used in containers and pipework for reactive and corrosive chemicals. Where used as a lubricant, PTFE ...

Tapered Roller Bearing
Tapered roller bearings are rolling element bearings that can support axial forces (i.e., they are good thrust bearings) as well as radial forces. Description The inner and outer ring raceways are segments of cones and the rollers are tapered so that the conical surfaces of the raceways, and the roller axes, if projected, would all meet at a common point on the main axis of the bearing. This geometry makes the motion of the cones remain coaxial, with no sliding motion between the raceways and the outside diameter of the rollers. This conical geometry creates a linear contact patch which permits greater loads to be carried than with spherical (ball) bearings, which have point contact. The geometry means that the tangential speeds of the surfaces of each of the rollers are the same as their raceways along the whole length of the contact patch and no differential scrubbing occurs. The rollers are stabilized and restrained by a flange on the inner ring, against which their la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crankshaft
A crankshaft is a mechanical component used in a piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating shaft containing one or more crankpins, that are driven by the pistons via the connecting rods. The crankpins are also called ''rod bearing journals'', and they rotate within the "big end" of the connecting rods. Most modern crankshafts are located in the engine block. They are made from steel or cast iron, using either a forging, casting or machining process. Design The crankshaft located within the engine block, held in place via main bearings which allow the crankshaft to rotate within the block. The up-down motion of each piston is transferred to the crankshaft via connecting rods. A flywheel is often attached to one end of the crankshaft, in order to smoothen the power delivery and reduce vibration. A crankshaft is subjected to enormous stresses, in some cases more than per cylinder. Crankshafts for single-cylin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuneaton
Nuneaton ( ) is a market town in the borough of Nuneaton and Bedworth in northern Warwickshire, England, close to the county border with Leicestershire and West Midlands County.OS Explorer Map 232 : Nuneaton & Tamworth: (1:25 000) : Nuneaton's population at the 2021 census was 94,634, an increase from 86,552 at the 2011 census making it the largest town in Warwickshire.
