Detail Information
Structure and function of connecting rod.
It is composed of three parts: big end of connecting rod,rod body and small end.Big end is separated, half of which is integrated with the rod body, and the other half is rod cap. Connecting rod cap is assembled with the main crankshaft journal by bolts and nuts.
Connecting rod connects the piston and the crankshaft, and transmits the force exerted by the piston to the crankshaft, transforming the reciprocating motion of the piston into the rotational motion of the crankshaft. It is one of the main transmission components of automotive engines, which transmits the pressure of the expanding gas of the piston to the crankshaft, transforming the reciprocating linear motion of the piston into the rotational motion of the crankshaft, in order to output power.
Raw Material and Forging.
Connecting rod materials are mostly made of high-strength SAE1045 carbon steel, ASTM5140/40Cr carbon steel, etc., through quenching and tempering treatment to improve cutting performance and impact resistance. The hardness requirements for SAE1045 carbon steel are HB217-293 and ASTM5140/40Cr is HB223-280.
Blank of connecting rods is generally produced by forging, and there are two forms of blank: one is the separate forging of the body and cap; Another method is to forge the body and cap integrated, and then cut apart when machining or use an expansion process to break them during the processing. In addition, to avoid defects of the blank, 100% hardness measurement and flaw detection are required.
What kind of connecting rod is a good connecting rod?
The working temperature of the connecting rod is 90~100 ℃, and the rotational speed is 3000~5000r/min. In order to ensure the smooth entry of connecting rod forgings to automated precision machining production lines and the assembly accuracy of processed finished parts in the engine, and to maintain their ability to withstand extremely high frequency of tensile and compressive alternating stress during high-speed operation, so that the crankshaft is always in a balanced state, it is required that the connecting rod forgings have high strength and fatigue lifetime.
