Splash Lubrication
Splash lubrication is a rudimentary form of lubrication found in early engines and transmissions. Such engines could be external combustion engines (such as stationary steam engines), or internal combustion engines (such as petrol, diesel or paraffin engines). Description An engine that uses splash lubrication requires neither oil pump nor oil filter. Splash lubrication is an antique system whereby scoops on the big end, big-ends of the connecting rods dip into the oil sump and splash the lubricant upwards towards the cylinders, creating an oil mist which settles into droplets. The oil droplets then pass through drillings to the bearings and thereby lubricate the moving parts. Provided that the bearing is a ball bearing or a roller bearing, splash lubrication would usually be sufficient; however, plain bearings typically need a pressure feed to maintain the oil film, loss of which leads to overheating and seizure. In a transmission, some of the gears are partially submerged in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robinson R22
The Robinson R22 is a two-seat, two-bladed, single-engined, light utility helicopter manufactured by Robinson Helicopter Company. It was designed in 1973 by Frank D. Robinson, and has been in production since 1979. Development The majority of flight testing was performed at Zamperini Field in Torrance, California. Flight testing and certification were performed in the late 1970s by test pilot Joseph John "Tym" Tymczyszyn, and the R22 received FAA certification in March 1979. Due to relatively low acquisition and operating costs, the R22 has been popular as a primary rotorcraft trainer around the world, entry-level personal helicopter, and as a livestock-management tool on large ranches in North America and cattle stations in Australia. The R22 has a very low-inertia rotor system Greenspun, Philip.2005 Robinson R22 - owner's review" March 2010.

Lubrication
Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology. Lubrication mechanisms such as fluid-lubricated systems are designed so that the applied load is partially or completely carried by hydrodynamic or hydrostatic pressure, which reduces solid body interactions (and consequently friction and wear). Depending on the degree of surface separation, different lubrication regimes can be distinguished. Adequate lubrication allows smooth, continuous operation of machine elements, reduces the rate of wear, and prevents excessive stresses or seizures at bearings. By repelling water and other substances, it also reduces corrosion. When lubrication breaks down, components can rub destructively against each other, causing heat, local welding, destructive damage and failure. Lubrication mechanisms Fluid-lubricated systems As the load incre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oil Pressure
Oil pressure is an important factor in the longevity of most internal combustion engines.{{Cite web , last=McTaggart , first=Megan , date=2021-02-25 , title=What Causes Low Oil Pressure (& How To Fix It) , url=https://www.lubezone.com/blog/what-causes-low-oil-pressure/ , access-date=2024-10-15 , website=LubeZone , language=en-US With a forced lubrication system (invented by Frederick Lanchester), oil is picked up by a positive displacement oil pump and forced through oil galleries (passageways) into bearings, such as the main bearings, big end bearings and camshaft bearings or balance shaft bearings. Other components such as cam lobes and cylinder walls are lubricated by oil jets. Sufficient oil pressure ensures that the metal of the rotating shaft (journal) and the bearing shell can never touch, and wear is therefore confined to initial start-up and shutdown. The oil pressure, combined with the rotation of the shaft, also hydrodynamically centers the journal in its shell and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential (mechanical Device)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others. A common use of differentials is in motor vehicles, to allow the wheels at each end of a drive axle to rotate at different speeds while cornering. Other uses include clocks and analogue computers. Differentials can also provide a gear ratio between the input and output shafts (called the "axle ratio" or "diff ratio"). For example, many differentials in motor vehicles provide a gearing reduction by having fewer teeth on the pinion than the ring gear. History Milestones in the design or use of differentials include: * 100 BCE–70 BCE: The Antikythera mechanism has been dated to this period. It was discovered in 1902 on a shipwreck by sponge divers, and modern research suggests that it used a differential gear to determine the angle between the ecliptic positions of the Sun and Moon, and thus the phase of the Moon. ...

Truck
A truck or lorry is a motor vehicle designed to transport freight, carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a " tractor". The majority of trucks currently in use are powered by diesel engines, although small- to medium-size trucks with gasoline engines exist in North America. Electrically powered trucks are more popu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norton Motorcycle Company
The Norton Motorcycle Company (formerly Norton Motorcycles.) is a brand of motorcycles headquartered in Solihull, West Midlands, (originally based in Birmingham), England. For some years around 1990, the rights to use the name on motorcycles were owned by North American financiers. Currently it is owned by Indian motorcycle giant TVS Motor Company. The business was founded in 1898 as a "fittings and parts for the two-wheel trade" manufacturer.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 a long history of racing involvement. During the Second World War Norton produced almost 100,000 of the military Model 16 H and Big 4 sidevalve motorcycles. Associated Motor Cycles bought the company in 1953. It was reformed as Norton-Vil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BSA Motorcycles
BSA motorcycles were made by the Birmingham Small Arms Company Limited (BSA), which was a major British industrial combine, a group of businesses manufacturing military and sporting firearms; bicycles; motorcycles; cars; buses and bodies; steel; iron castings; hand, power, and machine tools; coal cleaning and handling plants; sintered metals; and hard chrome process. A government-organised rescue operation in 1973 led to the takeover of BSA-Triumph motorcycle operations by Norton-Villiers, later known as Norton Villiers Triumph. At its peak, BSA (including Triumph) was the largest motorcycle producer in the world. In the late 1950s and early 1960s poor management and failure to develop new products in the motorcycle division led to a dramatic decline of sales to its major USA market. The management had failed to appreciate the importance of the resurgent Japanese motorcycle industry, leading to problems for the entire BSA group. When Norton Villiers Triumph was liquidated in ...

Triumph Engineering
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.Chadwick, Ian"Triumph Motorcycles timeline".Retrieved 31 December 2024. A year later, the company was registered as the New Triumph Co. Ltd, now ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unit Construction
: ''For the vehicle design where the vehicle's skin is used as a load-bearing element, see Monocoque.'' Unit construction is the design of larger motorcycles where the engine and gearbox components share a single casing. This sometimes includes the design of automobile engines and was often loosely applied to motorcycles with rather different internal layouts such as the flat twin BMW Motorrad, BMW models. Prior to unit construction, the engine and gearbox had separate casings and were connected by a primary chain drive running in an oil bath chaincase. The new system used a similar chain drive and both had separate oil reservoirs for engine, gearbox and primary drive. Triumph and BSA were already using cast non-ferrous alloy chaincases and started converting to unit construction in the 1950s. A driving factor behind the BSA/Triumph change was that Lucas Industries, Lucas had declared an intention to abandon production of motorcycle dynamos and ignition magneto, magnetos, and ...
