Norton Model 7 Dominator
The Norton Model 7 Dominator was a 500 cc vertical twin motorcycle manufactured by the Norton Motorcycle Company from 1949 to 1955. It was the first of Norton's Dominator range of motorcycles. The engine was designed by Bert Hopwood and was a departure from Norton's previous practice of producing single-cylinder machines. The Model 7 was used in Japan as a police motorcycle. Background In post-WW2 Britain, motorcycle manufacturers were getting back to production of civilian machines following the production of military machines. The British Government had launched an 'Export or Die' campaign to aid the economic recovery from war. Triumph's 1937 Speed twin had been well received and other manufacturers started to design their own 500 cc twins. Having worked under designers Val Page at Ariel and Edward Turner at Triumph, where he assisted with the design of the Triumph Speed Twin, Hopwood was poached by Norton to design a new twin engine. The new Model 7 Dominator, using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triumph Engineering Co Ltd
Triumph Engineering Co Ltd was a British motorcycle manufacturing company, based originally in Coventry and then in Meriden. A new company, Triumph Motorcycles Ltd, based in Hinckley, gained the name rights after the end of the company in the 1980s and is now one of the world's major motorcycle manufacturers. Origins The company was started by Siegfried Bettmann, who had emigrated from Nuremberg, part of the German Empire, to Coventry in England in 1883. In 1884, aged 20, Bettmann had founded his own company, the S. Bettmann & Co. Import Export Agency, in London. Bettmann's original products were bicycles, which the company bought and then sold under its own name. Bettmann also distributed sewing machines imported from Germany. In 1886, Bettmann sought a more specific name, and the company became known as the Triumph Cycle Company. A year later, the company was registered as the New Triumph Co. Ltd, now with funding from the Dunlop Pneumatic Tyre Company. During that year ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camshaft
A camshaft is a shaft that contains a row of pointed cams, in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers. Camshafts in piston engines are usually made from steel or cast iron, and the shape of the cams greatly affects the engine's characteristics. History Trip hammers are one of the early uses of a form of cam to convert rotating motion, e.g. from a waterwheel, into the reciprocating motion of a hammer used in forging or to pound grain. Evidence for these exists back to the Han Dynasty in China, and they were widespread by the medieval period. The camshaft was described in 1206 by engineer Al-Jazari. He employed it as part of his automata, water-raising machines, and water clocks such as the castle clock. Once the rotative version of the steam engine was developed in the late 18th century, t ...

Bushing (bearing)
A plain bearing, or more commonly sliding contact bearing and slide bearing (in railroading sometimes called a solid bearing, journal bearing, or friction bearing), is the simplest type of bearing, comprising just a bearing surface and no rolling elements. Therefore, the journal (i.e., the part of the shaft in contact with the bearing) slides over the bearing surface. The simplest example of a plain bearing is a shaft rotating in a hole. A simple linear bearing can be a pair of flat surfaces designed to allow motion; e.g., a drawer and the slides it rests on or the ways on the bed of a lathe. Plain bearings, in general, are the least expensive type of bearing. They are also compact and lightweight, and they have a high load-carrying capacity. Design The design of a plain bearing depends on the type of motion the bearing must provide. The three types of motions possible are: * ''Journal'' (''friction'', ''radial'' or ''rotary'') ''bearing'': This is the most common type of p ...

Conrod
A connecting rod, also called a 'con rod', is the part of a piston engine which connects the piston to the crankshaft. Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. The connecting rod is required to transmit the compressive and tensile forces from the piston. In its most common form, in an internal combustion engine, it allows pivoting on the piston end and rotation on the shaft end. The predecessor to the connecting rod is a mechanic linkage used by water mills to convert rotating motion of the water wheel into reciprocating motion. The most common usage of connecting rods is in internal combustion engines or on steam engines. __TOC__ Origins The predecessor to the connecting length is the mechanical linkage used by Roman-era watermills. The earliest known example of this linkage has been found at the late 3rd century Hierapolis sawmill in Roman Asia (modern Turkey) and the 6th century s ...

Roller Bearing
In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two concentric, grooved rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding. One of the earliest and best-known rolling-element bearings are sets of logs laid on the ground with a large stone block on top. As the stone is pulled, the logs roll along the ground with little sliding friction. As each log comes out the back, it is moved to the front where the block then rolls on to it. It is possible to imitate such a bearing by placing several pens or pencils on a table and placing an item on top of them. See " bearings" for more on the historical development of bearings. A rolling element rotary bearing uses a shaft in a much larger hole, and cylinders called "rollers" tightly fill the space between ...

Ball Bearing
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other. Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races. History Although bearings had been developed since ancient times, the first m ...

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- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earls Court Exhibition Centre
Earls Court Exhibition Centre was a major international exhibition and events venue just west of central London. At its peak it is said to have generated a £2 billion turnover for the economy. It replaced exhibition and entertainment grounds, originally opened in 1887, with an art moderne structure built between 1935 and 1937 by specialist American architect C. Howard Crane. With the active support of London mayor Boris Johnson, in an attempt to create Europe's "largest regeneration scheme", its proposed heritage listing was refused after it was acquired by developers, who promptly in 2008 applied for and were granted a Certificate of Immunity from Listing by English Heritage, and its demolition was completed in 2017. Located in Earl's Court but straddling the boundary between the Royal Borough of Kensington and Chelsea and the Borough of Hammersmith and Fulham, it was the largest such venue within the capital served by two London Underground stations—one of them, Earl's ...

Norton ES2
The Norton ES2 is a Norton motorcycle produced from 1927 until 1964. From 1965, a different machine was produced for a short time by parent manufacturer AMC, based on a Matchless but badged as Norton ES2 Mk2. Development It was a long stroke single, always 79mm x 100mm bore and stroke, originally launched as a sports motorcycle but throughout its long life it was gradually overtaken by more powerful models. It remained popular due to its reliability and ease of maintenance, as well as the traditional design. From 1947 the ES2 had an innovative hydraulically damped telescopic front fork and race developed rear plunger suspension. From 1953 it had a single downtube swinging-arm frame. Featherbed frame From 1959 it used the Rex McCandless designed Featherbed frame, with upgrades featuring an improved AMC gearbox, revised cylinder head, crankshaft-mounted Lucas RM15 60-watt alternator with coil ignition and an 8-inch front brake with full width hubs front and rear.The Motor ...

Edward Turner (motorcycle Designer)
Edward Turner (24 January 1901 – 15 August 1973) was an English motorcycle designer. He was born in Camberwell in the London Borough of Southwark, on the day King Edward VII was proclaimed King. In 1915, Turner had his first ride on a motorcycle, a Light Tourist New Imperial. Turner Special On 16 April 1925 "The Motor Cycle" published drawings by Turner of an OHC single he had designed, using a series of vertically stacked gears to drive the overhead camshaft. A subsequent redesign used bevel gears to drive a vertical camshaft, operating the valves through rockers. The only shared aspects of the two designs were the bore and stroke, , with the barrel being sunk into the crankcases. The head could be removed from either design complete with undisturbed valve gear. Turner built his first bike in 1927, using his second design, a 350 cc OHC single. ''The Motor Cycle'' published a photograph of Turner's patented engine, mounted in his motorcycle called the Turner Spec ...
