Description

Technical Field

[0001] The utility model relates to the technical field of crankshafts, in particular to a crankshaft structure. Background Art

[0002] The crankshaft is the most critical component in the engine. It receives force from the connecting rod, converts it into torque, and drives the engine's accessories. The crankshaft is subject to the combined effects of centrifugal force from the rotating mass, cyclically changing gas inertia, and reciprocating inertia, subjecting it to bending and torsional loads. Therefore, the crankshaft must possess sufficient strength and rigidity, and its journal surface must be wear-resistant, operate evenly, and be well-balanced.

[0003] The existing crankshaft structure has a poor protective effect, which makes it easy for the connector to be blocked and damaged due to its exposure. Utility Model Content
