FAW Truck Engine Crankshaft
FAW ENGINE CRANKSHAFT is the most important part of the engine.
ENGINE CRANKSHAFT DESCRIPTION:
FAW ENGINE CRANKSHAFT is the most important part of the engine. It inherits the force from the connecting rod and transforms it into torque, which outputs through the crankshaft and drives other accessories on the engine. The crankshaft is subjected to the centrifugal force of the mass of rotation, the inertia force of inertia and the inertia force of the cycle, and the crankshaft is subjected to the bending torsion load. Therefore, the crankshaft needs sufficient strength and stiffness. The surface of the journal needs to be wear resistant, uniform and balanced.
In order to reduce the FAW ENGINE CRANKSHAFT mass and the centrifugal force generated during movement, the crankshaft journal is often hollow. An oil hole is arranged on the surface of each journal so that oil can be introduced or drawn to lubricate the journal surface. In order to reduce the stress concentration, the connection between the spindle neck, the crank pin and the crank arm is connected by transitional arc.
The balance weight of FAW ENGINE CRANKSHAFT (also called counterweight) is used to balance the rotational centrifugal force and its torque, and sometimes it can balance reciprocating inertia force and torque. When the force and moment are self balanced, the balance can be used to reduce the load of the main bearing. The number, size and location of counterweight must be considered in terms of cylinder number, cylinder arrangement and crankshaft shape. The balance weight is usually combined with the crankshaft casting or forging. The balance weight of the heavy duty diesel engine is made separately from the crankshaft, and then connected by bolts.
