XCMG Loader Middle Sleeve (272200522): Material, Process & Core Functions
Material & Manufacturing Process:
The middle sleeve is crafted from high-strength alloy steel or bearing steel, optimized for durability under heavy loads. Key processes include:
Heat Treatment: Quenching (hardening) and tempering to achieve a surface hardness of HRC 58-62 and a tough core, balancing wear resistance and impact tolerance.
Precision Machining: CNC turning and grinding ensure dimensional accuracy (tolerance ≤ ±0.01mm) and surface finish (Ra ≤1.6μm) to minimize friction.
Surface Treatment: Optional anti-corrosion coatings enhance longevity in harsh environments.
Axial Positioning: Maintains precise alignment of gears on the transmission intermediate shaft, preventing misalignment-induced wear.
Load Distribution: Absorbs and redistributes axial forces from gear engagement, protecting bearings and shaft integrity.
Friction Reduction: Smooth surface finish minimizes energy loss and heat generation during high-speed rotation.
Component Isolation: Acts as a spacer to prevent direct contact between adjacent gears or bearings, reducing vibration and noise.
