The cone crusher socket liner, a replaceable wear-resistant component in the socket’s bearing cavity, acts as an interface between the rotating main shaft and stationary socket. It protects against wear, reduces friction (≤0.15 with lubrication), distributes loads, and compensates for minor misalignment, requiring good wear resistance and lubricant compatibility. Structurally, it is a cylindrical/flanged sleeve with a liner body (bronze, babbitt, or bimetallic materials), inner bearing surface (Ra0.8–1.6 μm with oil grooves), outer surface (interference fit), optional flange, lubrication features, and chamfers, with 5–15 mm wall thickness. Manufacturing involves casting (centrifugal/sand) for bronze liners, plus heat treatment and machining, or steel shell preparation, bearing layer application (sintering/roll bonding) and machining for bimetallic ones. Quality control includes material testing (composition, hardness), dimensional checks (CMM, roundness testing), microstructural analysis, performance tests (friction, wear), and fit checks, ensuring it protects components for efficient crusher operation
The cone crusher socket, a key component at the moving cone's bottom, functions as a pivot for the main shaft, transmits loads to the frame, facilitates lubrication, and maintains alignment. It operates under high loads, requiring strength, wear resistance, and precision. Structurally, it includes a high-strength alloy steel (42CrMo) body, a precision bearing cavity, eccentric bushing interface, lubrication channels, a mounting flange, and locating pins, with optional wear-resistant inserts. Manufacturing involves sand casting (pattern making, molding, melting/pouring), heat treatment (quenching/tempering, local hardening), and machining (precision boring, flange processing, channel drilling). Quality control covers material testing (composition, mechanics), dimensional checks (CMM, roundness testing), NDT (UT, MPT), mechanical tests (hardness, compression), and functional trials. These ensure it supports stable crusher operation in mining and aggregate processing.
