Tungsten Heavy Metal Crankshaft Block

Tungsten Heavy Metal Crankshaft Block

The tungsten alloy crankshaft, commonly called crank, is the part of an engine which has the function of translating reciprocating linear piston motion into rotation with the component of "crank throws" or "crankpins", It typically connects to a flywheel to reduce the pulsation characteristic of the four-stroke cycle, and sometimes there is a tensional or vibration damper at the opposite end for the purpose of reducing the torsion vibrations caused along the length of the crankshaft by the cylinders farthest from the output end acting on the tensional elasticity of the metal. The tungsten alloy crankshaft block is grinded to increase the mixture flow and has a special shape to reduce turbulences inside the crankcase. 

The application of tungsten alloy crankshaft block is an exercise in compromise. Depending upon the engine’s number of cylinders, crank configuration, and firing order, the mass properties and location of counterweights can vary. Counterweights can balance dynamic loads and couples, tungsten alloy crankshaft block can be used to alter tensional shaft dynamics, and they can be used to reduce main bearing radial and pin bending loads.

With a crank design that has limited throw clearance in the sump, like an F1 engine, using a counterweight material with high density (like tungsten) minimizes the radial space needed for a given counterweight. 

From a technical point’s view, no engine regardless of the application can benefit from balancing. As tungsten alloy crankshaft block has high density, so adding tungsten alloy crankshaft balance weight into the racing car has good effected in optimizing the performance of the racing car during the racing progress. Tungsten alloy crankshaft block contributes to the better control of the car's movement.

Tungsten alloy crankshaft block often used to counterweight. The tungsten alloy crankshaft block counterweight means that the sum of all the forces is roughly equal to zero at any point in the assembly's rotation, of which the operation is done by the tungsten alloy crankshaft counterweights. It is critical that the crankshafts must be balanced to customized rod and piston combination.
