Useful tips: Wear causes of crankshaft:
Journal of oval wear is due to the force acting on the shaft neck
caused by uneven distribution of direction along the circumference.
Engine working, the connecting rod journal of comprehensive forces always
acting on the inner side of the connecting rod journal, outward
direction along the radius of the crankshaft, connecting rod shaft
caused by internal jugular side wear is the largest, forming the
oval. Connecting rod journal causes of conical wear is due to the
connecting rod journal oil way is tilted, when the crankshaft
rotation, in under the action of centrifugal force, the partial
product lubriing oil of mechanical impurities in the side of the
connecting rod journal, speeding up the side of the journal of
wear, make a cone-shaped connecting rod journal wear. In addition,
the connecting rod bending, the center line of the cylinder and the
center line of the crankshaft is not vertical, can make the axial
uneven journal, and make the wear deflection.
Main journal wear oval, mainly due to the connecting rod,
connecting rod journal and the crank arm to the influence of
centrifugal force, close to the side of the connecting rod journal
and the bearing wear relatively larger. In addition, the journal
surface bruises and burns may occur. Abrasion is mainly due to the
oil not clean, hard mechanical impurities in the journal of larger
surface caused by score. Burn on the surface of the journal is
caused by burning tile, tile burning is mainly due to the
insufficient lubriion oil block, engine oil is too thin, etc.
