A connecting rod, also called a 'con rod', [1] [2] [3] 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. [4] The connecting rod is required to transmit the compressive and tensile forces from ...
A return connecting rod, [1] [2] return piston rod [i] or (in marine parlance) double piston rod engine [2] or back-acting engine is a particular layout for a steam engine. The key attribute of this layout is that the piston rod emerges from the cylinder to the crosshead , but the connecting rod then reverses direction and goes backwards to the ...
Crankshaft, pistons and connecting rods for a typical internal combustion engine Marine engine crankshafts from 1942. The crankshaft is located within the engine block and held in place via main bearings which allow the crankshaft to rotate within the block. [3] The up-down motion of each piston is transferred to the crankshaft via connecting ...
Connecting rod / Main rod Steel arm that converts the reciprocating motion of the piston into a rotary motion of the driving wheels. The connection between piston and main rod is a crosshead, which slides on a horizontal bar behind the cylinder. [2] [5] [3]: 55 Piston rod Connects the piston to the cross-head. [2] [3]: 61 Piston
In internal combustion engines, the gudgeon pin (English, wrist pin or piston pin US English) connects the piston to the connecting rod, and provides a bearing for the connecting rod to pivot upon as the piston moves. [1] In very early engine designs, including those driven by steam, and many very large stationary or marine engines, the gudgeon ...
The vertical piston rod of a large beam engine at Dorothea Quarry. In a piston engine, a piston rod joins a piston to the crosshead and thus to the connecting rod that drives the crankshaft or (for steam locomotives) the driving wheels. Internal combustion engines, and in particular all current automobile engines
A piston is a component of reciprocating engines. It is located in a cylinder and is made gas-tight by piston rings. Its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In two-stroke engines the piston also acts as a valve by covering and uncovering ports in the cylinder ...
A trunk engine locates the connecting rod within a large-diameter hollow piston. This "trunk" carries almost no load. The interior of the trunk is open to outside air, and is wide enough to accommodate the side-to-side motion of the connecting rod, which links a gudgeon pin at the piston head to an outside crankshaft.
