Cone Crusher adapter ring

The cone crusher adapter ring, a key component between the main shaft and moving cone, transmits torque and axial loads, compensates for minor misalignment, protects high-cost parts, and eases assembly. It operates under high torque and cyclic loads, demanding strength and precision.​ Structurally, it features a tapered alloy steel (40CrNiMoA or 45#) body with a precision inner taper (1:10 to 1:20), outer threads/flange, keyway, lubrication grooves, and a positioning shoulder.​ Manufacturing involves forging (heating to 1150–1200°C, upsetting/piercing) or casting, followed by quenching/tempering (HRC 28–35). Machining includes precision grinding of the taper (Ra0.8 μm) and threading.​ Quality control covers material testing (composition, tensile/impact strength), dimensional checks (CMM, taper gauge), NDT (UT, MPT), torque/fatigue testing, and assembly validation. These ensure reliable performance in torque/load transmission for efficient crusher operation.​
