What is the function of the engine crankshaft
Mar 01, 2023| The function of the engine crankshaft is to convert the thrust transmitted from the piston connecting rod into a rotating torque, converting the reciprocating linear motion of the piston into a circumferential rotation of the crankshaft, and then transmitting the engine torque to the transmission system through the flywheel. At the same time, it also drives the engine's valve train and other auxiliary devices.
The function of the engine crankshaft is to convert the thrust transmitted from the piston connecting rod into a rotating torque, converting the reciprocating linear motion of the piston into a circumferential rotation of the crankshaft, and then transmitting the engine torque to the transmission system through the flywheel. At the same time, it also drives the engine's valve train and other auxiliary devices.
The role of the crankshaft is that the crankshaft is the most important component in the engine. It bears the force transmitted from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine to work. The crankshaft is subjected to the combined action of the centrifugal force of the rotating mass, the periodically varying gas inertia force, and the reciprocating inertia force, making the crankshaft withstand bending and torsional loads.
The following are the functions of the crankcase:
1. The crankcase is the most important component in an engine. It bears the force transmitted from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine to work;
2. The crankcase is subjected to the combined action of the centrifugal force of the rotating mass, the periodically varying gas inertia force, and the reciprocating inertia force, making the crankshaft withstand the bending and torsional load;
3. Prevent oil deterioration; Prevent leakage of crankshaft oil seal and crankcase gasket.
