The connecting rod is one of the five big engine, engine is important safety pieces. The quality of the connecting rod directly influence engine performance and security. The connecting rod from the structure is plex, but the connecting rod belongs to the typical irregular parts and high accuracy, connecting rod processing technology is plex. This article through to the connecting rod processing technology introduction, and targeted support for connecting rod broken of new technology and new materials for specific process analysis, to realize the development of the advanced nature of the connecting rod processing.
The connecting rod is to transfer the power of the important moving parts, it small head with the pistons for reciprocating motion, the major part of the crankshaft rotary motion, as with the rod body in size head movement under the synthesis of swing. In addition to withstand cyclical change, as well as gas impact bear the larger the inertial force. This requires connecting rod fatigue resistance, impact resistance, and have the enough strength, stiffness and good toughness.
Because the structure of the engine is different, connecting rod structure vary slightly. But its basically piston sales by KongDuan (small head end), crankshaft pin KongDuan (big head end) and rod body of three parts. The crankshaft pin KongDuan for separate structure, body and cov
