Tractor Drive Shaft

The tractor drive shaft as the core component for power transmission in modern agricultural machinery, undertakes the key task of efficient and stable connection between the engine and agricultural machinery. Its design needs to take into account universal transmission, load carrying capacity, durability and maintenance convenience to adapt to the complex farmland operation environment.

The tractor drive shaft is mainly composed of a drive shaft tube, universal joints, connecting sleeves and fixing bolts. The transmission shaft tube is made by rolling and welding high-strength low-carbon steel plates. The wall thickness design must meet the critical speed and torsional strength requirements to avoid the risk of resonance fracture. Universal joints, as the core transmission components, achieve multi-angle power transmission through cross shafts and needle roller bearings. Their design needs to take into account both transmission efficiency and service life.

Material and process upgrade

Application of high-strength materials

The tractor drive shaft tube is made of high-strength steel, with tensile strength increased by 30%, and is suitable for high-power models.

The surface of the universal joint cross shaft is chrome-plated, which doubles its corrosion resistance and extends its service life.

Process optimization

The tractor drive shaft adopts laser welding technology, which increases the weld strength by 40% and reduces the risk of fracture.

The key parts (such as universal joint forks) adopt precision casting technology, with dimensional accuracy reaching ±0.1mm, reducing transmission errors.

The tractor drive shafts produced by Shuoxin®, as the power hubs of agricultural machinery, directly determine the operational efficiency and equipment lifespan. Through material innovation, structural optimization and intelligent upgrading, we provide farmers with more reliable transmission solutions.
