Wheels coupled to the main/side rods, through which the power developed in the cylinders (24) is transformed into tractive power at the rails. [ 1 ] [ 2 ] [ 5 ] [ 3 ] : 28 The weight of bearings and coupling rods on the driving wheels is counterbalanced with cast-in weights to reduce "hammering" on the track when the locomotive is under way.
An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
Using a 100-long-ton (100 t) vertical press, load testing was conducted of the strength and elasticity of the SCOA-P wheel centre against a 2,021 lb (917 kg) conventional spoked driving wheel centre of an A2 class locomotive that had the same diameter, but was engineered for a lower 17.5-long-ton (17.8 t) axle load). The tests revealed that the ...
This is a list of auto parts, which are manufactured components of automobiles. This list reflects both fossil-fueled cars (using internal combustion engines) and electric vehicles; the list is not exhaustive. Many of these parts are also used on other motor vehicles such as trucks and buses.
The number of driving wheels on locomotives varied quite a bit. Some early locomotives had as few as two driving wheels (one axle). The largest number of total driving wheels was 24 (twelve axles) on the 2-8-8-8-2 and 2-8-8-8-4 locomotives. The largest number of coupled driving wheels was 14 (seven axles) on the ill-fated AA20 4-14-4 locomotive.
Skirt guard or coatguard: a device fitted over the rear wheel of a bicycle to prevent a long skirt, coat or other trailing clothes or luggage from catching in the wheel, or in the gap between the rim and the brakes; Spindle: an axle around which a pedal rotates; threaded at one end to screw into crank arms; Spoke: connects wheel rim to hub ...
In a steam engine, cutoff is the point in the piston stroke at which the inlet valve is closed. On a steam locomotive , the cutoff is controlled by the reversing gear . The point at which the inlet valve closes and stops the entry of steam into the cylinder from the boiler plays a crucial role in the control of a steam engine.
The Lackawanna Cut-Off Restoration Project is a New Jersey Transit and Amtrak effort to restore passenger service to the Lackawanna Cut-Off in northwest New Jersey.. Started in 2011, Phase 1 of the project is extending NJ Transit's commuter rail service 7.3 miles (11.7 km) from Port Morris Junction in Morris County to Andover in Sussex County, with the latter seeing its first passenger trains ...
