Cone Crusher Sheave

This paper elaborates on the sheave (pulley) of cone crushers, a key power transmission component that transfers rotational motion from the motor to the countershaft via a drive belt, adjusts countershaft speed, and absorbs vibration. It details its composition and structure, including the sheave body, V-grooves, hub, rim, and web. The casting process for the sheave body is outlined, covering material selection (gray cast iron), pattern making, molding, melting, pouring, heat treatment, and inspection. It also describes the machining process (rough/finish machining, surface treatment) and assembly features. Additionally, quality control measures are specified, such as material testing, dimensional accuracy checks, balancing, functional testing, and surface quality inspection. These processes ensure the sheave enables efficient power transmission, reducing belt wear and enhancing the cone crusher’s operational reliability
