3310653 XCMG GR2605 motor grader sun gear shim
3310653 Sun Gear Shim is a special thrust and adjustment washer for planetary reduction systems in construction machinery. It is mainly installed between the sun gear and the planet carrier or bearing to accurately control the axial clearance of the sun gear, cushion end-face impact, reduce friction and wear, ensure stable meshing of the planetary gear train, and improve the reliability and service life of the transmission system.
Technical Parameters
- Model: 3310653
- Type: Sun Gear Thrust Shim / Adjusting Shim
- Material: High-hardness wear-resistant alloy steel plate
- Surface Treatment: Precision flat grinding, blackening anti-rust treatment
- Hardness: HRC45～50, compression-resistant and wear-resistant without deformation
- Thickness: Standard fixed thickness with high dimensional accuracy
- Operating Temperature: -40℃～120℃
- Structure: Annular thin sheet with high concentricity and flat end face without burrs
Application Scenarios
Suitable for drive axles, wheel reducers, planetary gearboxes, swing mechanisms and other parts of construction machinery such as loaders, graders, rollers and forklifts. Installed between the sun gear end face and the planet carrier or bearing for axial clearance compensation, positioning support and wear protection, suitable for heavy-duty and continuous operation conditions.
Common Faults & Troubleshooting
- Thinning and excessive clearance: Caused by long-term high-speed friction. Replace 3310653 shim and readjust axial clearance.
- Crushing deformation and damage: Caused by overload or poor lubrication. Replace with a new shim and check gear meshing and lubrication status.
- Abnormal noise and heating during operation: Caused by missing or severely worn shim. Replace the shim in time to avoid direct wear on the sun gear end face.
- Dislocation and falling off: Caused by improper installation or damaged limit structure. Reassemble and check the positioning structure of the planet carrier.
