3349513 XCMG GR2605 motor grader gear ring

3349513 XCMG GR2605 motor grader gear ring

The 3349513 gear ring is a core meshing component in the transmission system of engineering machinery. It is widely used in wheel-side reducers, drive axles, and slewing mechanisms, meshing with planetary gears or drive gears to transmit high torque. It features strong load-bearing capacity, smooth meshing, wear resistance, and impact resistance, ensuring stable power output.

Technical Parameters

Model: 3349513
Material: High-strength alloy steel, overall tempering + tooth surface quenching
Tooth profile accuracy: Standard involute tooth profile, smooth meshing
Hardness: High tooth surface hardness, anti-pitting, wear-resistant
Applicable temperature: -40℃～120℃
Lubrication method: Gear oil splash lubrication
Installation method: Internal gear ring/external gear ring structure, press-fit or bolt fixing

Suitable Scenarios

Suitable for wheel-side reducers, drive axles, gearboxes, slewing bearings, etc., in engineering machinery such as loaders, graders, road rollers, and excavators; used for high torque power transmission, suitable for heavy-duty, continuous operation, and high-impact conditions.

Common Faults and Troubleshooting

Tooth surface wear, pitting, and spalling: Poor lubrication, overload, or improper meshing clearance. Replace the 3349513 gear ring and check the gear pair clearance.

Broken teeth and chipped corners: Severe impact loads or material fatigue. Replace the gear ring directly and check for impact sources in the transmission system.

Abnormal noise and vibration during operation: Gear ring misalignment or abnormal fit clearance. Realign the installation position and tighten.

Inner bore/locating surface wear: Caused by long-term loose operation. Replace the gear ring and repair the mounting seat mating surfaces.
