Liugong 72A3325 Side Gear: Rigid power transmission as solid as a rock, firmly establishing the core defense line for power transfer.

In the power transmission chain of construction machinery, the side teeth are responsible for transmitting power. “ Rigid hub — It connects the power source to the actuator, and every time the equipment is started or the load is running, precise meshing of the side teeth is required to transmit torque. If the side teeth suffer from tooth surface wear, tooth body fracture, or loosening of the meshing engagement, it will directly lead to power interruption and operational stalling. At best, this results in abnormal noises and reduced efficiency; at worst, it can cause cascading damage to the power transmission components, leading to prolonged downtime for repairs. LiuGong 72A3325 The side teeth, as a factory-customized core power component, boast a robust structure and precise fit, ensuring smooth and efficient power transmission with zero energy loss, thus laying a solid foundation for the equipment's high-performance operation.

Factory-exclusive compatibility: Perfectly meshed, transmitting power with zero backlash.

The meshing accuracy of the side teeth directly determines the transmission efficiency, LiuGong. 72A3325 R&D entirely based on the parameter specifications of the power transmission components for specific aircraft models: The tooth profile curves, module, and pitch have been calibrated through 3D modeling by the original manufacturer, ensuring that the meshing accuracy with the mating gears meets the original manufacturer’s standards and completely eliminating non-original side teeth. “ Misalignment of engagement causes jamming. ” the issue; the tip circle and root circle dimensions precisely match the transmission housing, allowing direct installation without the need for grinding or adjustment; the position and depth of the locating holes perfectly correspond to those of the transmission shaft, ensuring that axial play after assembly is kept within an extremely narrow range, thus eliminating any clearance loss during power transmission and guaranteeing that every bit of power is accurately transmitted to the actuator. Maintenance personnel can complete the replacement using only standard tools, quickly restoring the system’s power transmission performance.

Empowered by robust materials: impact-resistant and load-bearing, maintaining its shape even after prolonged use.

Facing the high-frequency torque impacts of the transmission system, 72A3325 The side teeth feature dual enhancements in both material and manufacturing process: They are entirely forged from high-strength alloy steel, which boasts a higher material density compared to conventionally cast side teeth. This enables them to effectively withstand the impact forces generated during sudden load changes, thereby preventing tooth fracture. After forming, the teeth undergo tempering heat treatment, achieving a balanced combination of core hardness and toughness. —— It ensures both wear resistance of the tooth surfaces and prevents excessive rigidity that could lead to brittle fracture. Even under harsh operating conditions such as heavy-load starts and frequent direction changes, it can stably transmit torque without causing tooth surface collapse or root fracture.

Precision machining process: smooth engagement, reduced friction and noise.

The machining accuracy of the side teeth is key to reducing wear and lowering noise, LiuGong. 72A3325 Employing multiple precision machining processes: The tooth surfaces undergo gear grinding, significantly enhancing surface finish and markedly reducing frictional resistance during meshing, thereby preventing engagement with non-original manufacturer gears. “ Rough tooth surfaces lead to rapid wear. ” The issue; the tooth profile error is controlled within the manufacturer’s specified tolerance range, and the transition fillets between the tooth top and root are smoothly rounded, ensuring even force distribution during meshing and reducing impact-induced wear. The locating end face undergoes a dual process of milling and grinding, resulting in higher conformity with the transmission shaft and minimizing radial runout during operation, thereby fundamentally reducing transmission noise and enabling smoother equipment operation.

Corrosion- and wear-resistant upgrade: Designed for harsh environments, extending service life.

Power transmission components in construction machinery are easily affected by oil contamination and dust. 72A3325 Targeted reinforcement for side teeth: The tooth surfaces undergo a carburizing and quenching process, forming a hard, wear-resistant layer that effectively resists abrasion caused by impurities in gear oil. The tooth body surface is treated with both phosphating and anti-rust oil, ensuring that even under long-term exposure to humid and dusty working conditions, the teeth remain protected against rust-induced surface flaking. The positioning and aperture of the gear oil passages are precisely matched to those of the original factory components, guaranteeing that lubricating grease fully covers the tooth surfaces, forming a stable oil film that further extends the service life of the meshing areas and reduces maintenance frequency.

End-to-end quality control: Original manufacturer standards, ensuring impeccable quality.

LiuGong vs. 72A3325 Side gears undergo rigorous, end-to-end inspections—from raw materials all the way to finished products: Raw materials must pass material composition analysis and mechanical property testing to ensure that the alloy steel meets quality standards. During the manufacturing process, each step is subject to dimensional accuracy checks, with particular emphasis on verifying critical parameters such as tooth profile and tooth pitch. At the finished-product stage, meshing performance tests, fatigue strength tests, and impact resistance tests are conducted to simulate long-term usage scenarios and validate stability. All side gears leaving the factory are equipped with original manufacturer’s traceability markings, ensuring full product traceability and completely eliminating the risk of counterfeit products.
