Problems solved by technology

[0002] The crankshaft is the most important part of the engine. It must have sufficient strength and rigidity to withstand the joint action of the centrifugal force of the rotating mass, the periodically changing gas inertial force and the reciprocating inertial force. The existing strength and stiffness of the crankshaft Still needs to be improved and further research is needed

Embodiment 1

[0013] A crankshaft comprising the following components in parts by weight: 0.28 parts of chromium, 0.16 parts of strontium, 0.3 parts of copper, 0.2 parts of molybdenum, 0.14 parts of antimony, 0.18 parts of barium, 0.3 parts of manganese, and the balance is iron and unavoidable impurities.

Embodiment 2

[0015] A crankshaft comprising the following components by weight: 0.38 part of chromium, 0.25 part of strontium, 0.4 part of copper, 0.23 part of molybdenum, 0.17 part of antimony, 0.2 part of barium, 0.3 part of manganese, and the balance is iron and unavoidable impurities.

[0016] This kind of crankshaft includes chromium, strontium, copper, molybdenum, antimony, barium, iron and manganese. In particular, elements such as chromium and strontium are added to the crankshaft component, which greatly improves the strength and toughness of the crankshaft. There is no risk of fracture, and it has good application prospects and is worthy of promotion.
