• 4N7693 4N-7693 Crankshaft Excavator Engine Parts Fitting For 235 235B 235C

• Specification

• Function

1.Power conversion: It converts the linear thrust from the piston - connecting rod into a rotational torque, achieving the transformation from the piston's reciprocating motion to the crankshaft's circular motion. This is the core function of the crankshaft, which converts the thermal energy generated by the fuel's combustion in the engine cylinder into mechanical energy.

2.Power output and transmission: The crankshaft transmits the generated torque to the transmission system through the flywheel, providing power for the movement of construction machinery, such as driving the wheels of loaders and tractors to rotate, enabling the equipment to complete various operations.
