3132823 XCMG GR2605 motor grader planetary gear

The 3132823 planetary gear is a core transmission component of planetary reduction mechanisms in construction machinery. It works with the sun gear and ring gear to achieve speed reduction and torque amplification. Primarily used for transmitting torque and supporting loads, it features wear-resistant tooth surfaces, impact resistance, and smooth meshing. It is a key gear component in drive axles and wheel-side reducers.

Technical Parameters

Model: 3132823
Material: High-strength alloy structural steel, tempered and hardened on the tooth surface
Tooth Surface Hardness: High hardness, resistant to pitting, wear, and fatigue
Structure: With a central shaft hole, suitable for planetary shafts and needle roller bearings
Precision: High tooth profile precision, stable meshing clearance, smooth operation
Applicable Temperature: -40℃～120℃
Lubrication Method: Gear oil splash lubrication

Suitable Scenarios

Suitable for wheel-side reducers, drive axles, and planetary gear mechanisms in construction machinery such as loaders, graders, and road rollers; used with the sun gear, internal ring gear, and planetary shaft to form a reduction unit, suitable for heavy-duty, impact, and continuous operation conditions.

Common Faults and Troubleshooting

Gear surface wear, pitting, and spalling: Insufficient lubrication, overload, or improper clearance. Replace the 3132823 planetary gear and check the meshing clearance.

Abnormal noise and vibration during operation: Gear damage, bearing wear, or misalignment during installation. Replace the planetary gear and its matching bearing.

Inner bore wear and looseness: Long-term operation leads to increased clearance. Replace the planetary gear directly.

Broken teeth and chipped corners: Severe impact load or material fatigue. Replace the planetary gear and investigate the cause of system overload.
