2023-05-18

1、The crankshaft is an important part of the engine. It bears the force transmitted from the connecting rod and transforms it into torque through the crankshaft output and drives other accessories on the engine to work;

2、The crankshaft is subjected to the combined effect of centrifugal force of the rotating mass, cyclically varying gas inertia force and reciprocating inertia force, which subjects the crankshaft to bending torsional loads;

3、Prevent the oil from deteriorating; prevent the crankshaft oil seal and crankshaft liner from leaking.
