Definition of crank shaft in English Dictionary

The main shaft of an engine, so named because of the U-shaped cranks. It delivers rotary motion taken from the reciprocating pistons and rods.

A part of a Nitro engine that is rotated by the piston, providing circular motion to the outer part of the crank shaft, which is attached to the flywheel and CRANK SHAFT

2. Crank-shaft a rotating shaft driven by (or driving) a crank

3. Crank-shaft: The main rotating shaft in an engine that transfers the pistons' up and down motion into a smooth circular motion that is then used to drive the transmission and eventually the wheels.

4. Crank-shaft A shaft with one or more cranks, or "throws," that are coupled by connecting rods to the engine's pistons Together, the crankshaft and the con rods transform the pistons' reciprocating motion into rotary motion

6. Crank-shaft: The cranked shaft in an engine that changes the pistons linear motion into rotational motion Cush drive. A transmission shock absorber, usually a rubber cushion in the rear hub cylinder head. A casting that caps the cylinder and contains the valves and combustion chamber.

7. Crank-shaft: The main shaft inside the engine that turns the up-and-down motion of the pistons into rotational torque There are two types of crankshafts: cast iron and forged steel The cast variety are used in most passenger car engines while the stronger forged ones are used primarily in high performance applications When an engine is overhauled, the rod and main bearing journals are reground to restore a smooth surface Crankshaft failures are fortunately not very common, but when they happen it usually caused by excessive internal engine vibration or defects in the crankshaft itself.

8. Crank-shaft: The rotating shaft within the engine that delivers the power from the pistons to the flywheel.
