章節(jié)摘錄

　　The crankshaft is a one-piece casting or forging of heat treated alloy steel of Considerable mechani-cal strength. The crankshaft must be strong enough to take the downward thrusts of the pistons duringthe power strokes without excessive distortion. In addition, the crankshaft must be carefully balancedto eliminate undue vibration resulting from the weight of the offset cranks. To provide balance, crank-shafts have counterweights opposite the cranks. Crankshafts have drilled oil passages through which oilcan flow from the main to the connecting-rod bearings. The front end of the crankshaft carries three devices, the gear or sprocket that drives the cam-shaft, the vibration damper, and the fan belt pulley. The pulley drives the engine fan, water pump,and generator with a V belt. Flywheel The flow of power from the engine cylinders is not smooth. Although the power impulses overlap（ on six- and eight-cylinder engines）, there are times when more power is being delivered than at othertimes. This tends to make the crankshaft speed up and then slow down. However, the flywheel com-bats the tendency. The flywheel is a comparatively heavy wheel bolted to the rear end of the crank-shaft. The inertia of the flywheel tends to keep it turning at constant speed. Thus, the flywheel absorbsenergy as the crankshaft tries to speed up and gives back energy as the crankshaft tries to slow down.In effect, the flywheel absorbs power from the engine during the power stroke （or speedup time） andthen gives it back to the engine during the other three strokes （or slowdown time） of the cycle.
