Agricultural Machinery Connecting Rod
The agricultural machinery connecting rod is a core force-bearing transmission component of the power system for agricultural machinery such as tractors, harvesters and agricultural engines. It connects the agricultural machinery crankshaft to the piston (or the power output end to the executive component), and its core function is to convert the rotational motion of the crankshaft into linear motion, or transmit power and bear reciprocating loads and impact forces. It directly determines the efficiency and stability of agricultural machinery power transmission, is suitable for various heavy-load and long-time continuous operation scenarios of agricultural machinery, and is an indispensable key accessory for the agricultural machinery power system.
Two high-quality material options are available, accurately corresponding to European and American standards, to meet different agricultural machinery operation intensity requirements:
Cast Steel ZG35CrMo: Equivalent to European Standard EN 10025-2 16Mo3 / American Standard AISI 4130. It has excellent high strength, high toughness, impact resistance and creep resistance, wear resistance and corrosion resistance, and large load-bearing capacity. Suitable for heavy-duty agricultural machinery and high-load operation scenarios, it can effectively resist the impact and wear caused by complex field working conditions, and is not easy to deform or break.
Ductile Iron QT600: Equivalent to European Standard EN-GJS-600-3 / American Standard ASTM A536 80-55-06. It has high strength, good rigidity, outstanding fatigue resistance and anti-deformation ability, and excellent cost performance. Suitable for conventional operations of medium-sized agricultural machinery, it balances power transmission and use cost, and is compatible with most agricultural machinery power system specifications.
Adopting precision casting (for cast steel) / precision casting + CNC precision machining (for ductile iron) technology, the rod body has a reasonable structure, uniform wall thickness and balanced force. Reinforced design is added at key positions to improve the overall load-bearing capacity; the connecting holes at both ends have high dimensional accuracy, which fits the crankshaft and piston mounting interfaces, easy to assemble and accurately positioned, with smooth transmission without jamming; the surface is treated with anti-rust and anti-corrosion, resistant to field sediment and rain erosion, not easy to rust or wear, easy to maintain, and prolongs the service life.
It has strong compatibility, can match mainstream agricultural machinery models around the world, supports customization of the length, hole diameter, rod diameter and non-standard structure of the connecting rod according to customer needs, and adapts to the power transmission needs of agricultural machinery with different powers; the quality strictly complies with European and American standard testing standards, with up-to-standard materials and stable performance, suitable for foreign trade export, timely supply and reliable quality, effectively ensuring the efficient and stable operation of the agricultural machinery power system.
