Hi-TTS Diesel Engine Alloy Gold Crankshaft for Engineering Machinery Part Numbers SL K3500 K410-11-301A

A crankshaft is a crucial mechanical component in internal combustion engines, primarily used to convert the reciprocating motion of pistons into rotational motion.

Structure

.Main Journals:They are the cylindrical sections that rest on the engine block bearings, supporting the entire crankshaft and enabling it to rotate.
.Crankpins (Rod Journals):These are offset from the main axis of the crankshaft. The big ends of the connecting rods are attached to the crankpins, and they are the key parts for converting linear motion into rotational motion.
.Crank Webs (Arms):They connect the crankpins and main journals, playing a role in transferring the force from the connecting rods to the main journals.
.Counterweights:Positioned between the main journals and crankpins, they are used to balance the rotating assembly, reducing vibration and ensuring smooth operation of the engine.
.Oil Passages:Internal channels in the crankshaft are used to deliver engine oil to the main journals and crankpins for lubrication, reducing friction and wear.
