Cone Crusher Pinion

This paper provides a detailed overview of the cone crusher pinion, a critical transmission component that meshes with the bull gear to transfer motor power to the eccentric assembly, enabling the moving cone's oscillating motion. It elaborates on the pinion's functions, including power transmission, torque amplification, and precision meshing. The composition and structure are detailed, consisting of gear teeth, shaft body, bearing journals, shoulders/collars, lubrication holes, and keyway/spline, along with their structural characteristics. For large-scale pinions, the casting process is described, covering material selection, pattern making, molding, melting and pouring, cooling and shakeout, heat treatment, and inspection. For forged pinions, the machining and manufacturing process is outlined, including forging, rough machining, heat treatment, finish machining, and deburring/polishing. Additionally, quality control measures are specified, such as material validation, dimensional accuracy checks, hardness and microstructure testing, dynamic performance testing, non-destructive testing, and final inspection. These processes ensure the pinion achieves the required strength, precision, and durability, guaranteeing reliable power transmission in demanding crushing operations
