Cone Crusher Mainshaft Technical Overview

The Cone Crusher Mainshaft serves as the primary drive component in cone crushers. This forged steel shaft connects directly to the crushing head and transmits rotational power.

Key Functions

• Transfers motor/hydraulic power to the crushing head
• Supports crushing forces and impact loads
• Controls gyratory motion through eccentric bushing interaction

Design Features

• Eccentric middle section enables crushing stroke
• High-strength alloy steel construction (e.g., 42CrMo)
• Precision-machined bearing surfaces at both ends
• Heat-treated for maximum durability

Maintenance Requirements

• Monitor eccentric wear surfaces regularly
• Maintain proper lubrication to prevent fatigue cracks
• Ensure precise vertical alignment during installation

Brand-Specific Designs

• Sandvik uses monolithic mainshaft construction
• Metso incorporates hydraulic adjustment capability
• Symons employs traditional tapered designs

Critical Related Components

• Head Center determines crushing motion geometry
• Eccentric Bushing controls stroke characteristics
• Countershaft delivers drive power
