3310583 XCMG GR2605 motor grader sun gear
3310583 sun gear is a core transmission component in the planetary drive system of construction machinery. It mainly cooperates with planetary gears and ring gear to achieve power transmission, speed reduction and torque increase. Manufactured from high-strength alloy steel with precision forging, carburizing quenching and fine grinding, it features high tooth hardness and strong load capacity, ensuring stable and reliable transmission under heavy-duty, shock and continuous working conditions. It is widely used in key parts such as drive axles, wheel reducers and gearboxes.
Technical Parameters
- Model: 3310583
- Type: Planetary Transmission Sun Gear
- Material: High-strength alloy structural steel, integrally forged
- Heat Treatment: Carburizing & quenching + low-temperature tempering, precision ground tooth surface
- Tooth Surface Hardness: HRC58～62
- Operating Temperature: -40℃～120℃
- Structure: External teeth with internal spline or shaft hole in the center, high transmission accuracy
- Application: Heavy load, impact, vibration, continuous operation, high dust environment
Application Scenarios
Suitable for drive axles, wheel reducers, planetary gearboxes, travel and swing mechanisms of construction machinery such as loaders, graders, rollers and forklifts. As the central part of the planetary gear train, it works with planetary gears, ring gear and planet carrier for power transmission, speed reduction and torque increase, suitable for long-term continuous operation under harsh working conditions.
Common Faults & Troubleshooting
- Tooth wear, pitting or spalling: Usually caused by insufficient lubrication, overloading or foreign matter ingress. Replace 3310583 sun gear and check gear oil and mating parts.
- Abnormal noise and vibration: Caused by gear damage, improper meshing clearance or faulty support bearings. Replace the sun gear and calibrate assembly position.
- Spline wear and slipping: Resulted from long-term heavy load and impact with increased fitting clearance. Replace the sun gear directly and inspect the mating spline shaft.
- Tooth breakage: Caused by severe impact, overloading or material fatigue. Replace the sun gear and check for overloading causes in the transmission system.
