CRANKSHAFT FUNCTION
Combustion of the fuel-air mixture in the engine produces power. This power is transformed into rotary movement of the crankshaft. The linear motion of the pistons is converted by way of the connecting rod into a torque and is then passed to the flywheel.
The crankshaft has to withstand considerable loads in this process. On the one hand it is subjected to severe bending and torsional stress. Further loads arise from torsional vibration, as the rotary movement of the crankshaft is constantly being abruptly accelerated and decelerated. The bearings are also subject to a high degree of wear.
l CRANKSHAFT DESIGN AND COMPONENTS
To be able to withstand wear and the strain of rotary movement, crankshafts need to have a hard surface and a tough core. For this reason crankshafts are often forged. Alloyed heat-treated steel or nitrided steel is used as raw material. The crankshaft journals are also surface-hardened.
A crankshaft comprises the following components:
· Main journals
· Crank pins
· Crank webs
· Counterweights
Main journals run in the main bearings and define the axis of rotation of the shaft. The connecting rods are connected to the crank pins. Crank webs connect the crank pins to the main journals. The counterweights provide balancing and are attached to the webs.
The design of the crankshaft is determined by the firing order of the engine, the number of cylinders, the design of the engine, the size of the stroke and the number of crankshaft bearings.
Height-adjustable crankshaft mounting – using an eccentrically mounted crankshaft bearing for example – makes it possible to achieve variable compression. The advantage of variable compression is that fuel consumption can be reduced by up to 25 per cent in the part load range.

FAQ:
Q1. How about the processing technology?
A: Crankshaft finishing will extensively use a CNC-controlled crankshaft grinder to finish the journal. The grinding machine will be equipped with the automatic dynamic balancing device of the grinding wheel, automatic tracking device of the center frame, automatic measurement, automatic compensation device, automatic dressing of the grinding wheel, constant line speed and other functional requirements to ensure the stability of the grinding quality.Â
Q2. When will you delivery the products?
A: Â We will instantly send it after we receive your payment.
Q3. Could you provide the parts as the sample provided?
A: Yes, we can provide the parts as you want.
Q4. Could i get a sample?
