3132723 XCMG GR2605 motor grader sun gear
3132723 sun gear is a core transmission component of the planetary reduction mechanism for construction machinery. As the power input center, it cooperates with planetary gears and inner ring gear to achieve speed reduction and torque increase. Featuring high tooth surface hardness, strong load capacity and stable meshing, it is a key gear part for wheel reducers, drive axles and other components.
Technical Parameters
Model: 3132723
Type: Sun gear for planetary transmission
Material: High-strength alloy steel, quenched and tempered with tooth surface hardening
Surface Treatment: Blackening for rust prevention
Hardness: High hardness on tooth surface, wear and pitting resistant
Operating Temperature: -40℃～120℃
Structure: External gear design with splined or plain center hole, high transmission accuracy
Application Scenarios
Suitable for drive axles, wheel reducers and planetary gearboxes of construction machinery such as loaders, graders and rollers. Works with planetary gears, carriers and ring gears for power transmission and speed reduction under heavy-duty, shock and continuous working conditions.
Common Faults & Troubleshooting
Tooth wear, pitting or spalling: Caused by insufficient lubrication or overloading. Replace 3132723 sun gear and check gear oil condition.
Abnormal noise or vibration during operation: Result of gear damage or improper meshing clearance. Replace the sun gear and adjust assembly position.
Spline/bore wear: Loosening due to long-term stress. Directly replace with a new sun gear.
Tooth breakage or chipping: Caused by severe impact or material fatigue. Replace the sun gear and check for overloading in the transmission system.
