Automotive crankshaft 3D print model
A crankshaft is a shaft driven by a crank mechanism, consisting of a series of cranks and crankpins to which the connecting rods of an engine are attached.[1] It is a mechanical part able to perform a conversion between reciprocating motion and rotational motion. In a reciprocating engine, it translates reciprocating motion of the piston into rotational motion, whereas in a reciprocating compressor, it converts the rotational motion into reciprocating motion. In order to do the conversion between two motions, the crankshaft has crank throws or crankpins[clarification needed], additional bearing surfaces whose axis is offset from that of the crank, to which the big ends of the connecting rods from each cylinder attach.There are multiple files attached for every use.
