Crankshaft
The crankshaft changes the vertical piston movement to rotary motion, and transfers this rotary motion to the drivetrain. Crankshafts may contain cast iron alloy or forged steel. Cast iron crankshafts are satisfactory in car and light-duty truck engines. However,forged steel crankshafts provide increased strength compared with those made from cast iron alloy. All the main bearing and connecting rod bearing journals are machined to a highly polished finish. Bearing inserts are located between the main bearing bores and the main bearing journals on the crankshaft. Connecting rod bearing inserts are mounted between the connecting rod bores and the crankshaft journals. The main bearing journals must be perfectly aligned wish each other. Connecting rod journals are offset from the center of the crankshaft. Thererore, the connecting rod journals orbit around the main bearing journals. The cankshaft journals must be properly spaced so the pistons reach TDC in the correct drder.
Oil passages are drilled from each main bearing journal to the connecting rod journals to assure adequate oil supply at the connecting rod bearings.
A flexplate, or flywheel, is bolted to the transmission end of the crankshaft, and a vibration damper and pulley are pressed onto the front of the crankshft.
Bearing Inserts
Bearing inserts must have these characteristics;
1. Embedability to absorb foreign particles which may scratch the crankshaft journal.
2. Surface action to prevent bearing seizure to the crankshaft if the bearing insert
momentarily contacts the journal surface.
3. Conformability to allow bearing material to creep slightly and compensate for some
misalignment between the bearing insert and the crankshaft journal.
4. Fatigue strength to withstand severe sxplosion impacts from the combustion chamber,
piston, and connecting rod.
Commonly used bearing insert materials include steel-backed Babbit, overplated copper,
nonoverplated copper, overplated aluminum-cadmium, and nonoverplated aluminum.
Locking tabs on half of bearing insert fit into slots in the connecting rod or main bearing opening to prevent bearing rotation. Bearing inserts are designed so their curvature is slightly larger than the bore in which they are mounted. Therefore, when the bearing insert is installed it conforms exactly to the bore surface. This type of bearing insert design is called bearing spread.
When bearings are manufactured, they are designed so they are slightly longer than the bore in which they are insatalled;therefore, the edges of the bearing insert protrude a short distance from the bore. When the bearing cap is bolted in place, bearing crush and spread provide good heat dissipation from the bearing, and prevent bearing rotation in the bore.
A thin film of oil must be maintained between the bearing insert and the crankshaft journal. Correct bearing clearance is essential to maintain this film of oil.
