What Is A Crankshaft? | How does a Crankshaft Work?
Working of Crankshaft. A crankshaft works on the crank mechanism. A crank has multiple crankpins and cranks that are used to connect it with the connecting rods. It has a vibration damper that reduces the thrust on the crank. A crankshaft of a 4-stroke engine works in the following way:
Directions for crankshaft grinding and polishing
Grinding opens graphite nodules located at the surface of the journal leaving ragged edges which will damage a bearing. Polishing in the proper direction will remove the ragged edges from these open nodules.
Crankshaft: Parts, Function, Types, Diagram & More [PDF]
A crankshaft is an essential part of the power transmission system. In which, the reciprocating movement of the piston is converted into a rotating movement by using the connecting rod. A crankshaft consists of crankpins, crank webs (crank arms or cheeks), balancing weights, and main journals. The large end of the connecting rod is …

Crankshaft surfaces: Finishing methods, surface characterization and
Typical band-polished crankshaft surfaces Typically, the finishing of nodular iron crankshafts consists of turning the journals and crankpins, followed by grinding and then lapping them. Lapping is usually done using abrasive grit on a polymer backing ("band polishing"), but may also be done using a very fine abrasive stone ("micro- honing").
Crankshaft Grinding
The crankshaft grinding wheel is secured with a hub, balanced and mounted to the machines arbor to accommodate operation at high RPMs. The surface finish on most grinding wheels is 54 grit, which is a similar specification as used for sandpaper. The most common grinding wheels accommodate an arbor size of 3", 5" and 8" for …
