Support Spring Assembly
Product Overview
As a specialized spare part tailored for Nanchang Mining Machinery's screening equipment, the Support Spring Assembly serves as a critical structural component dedicated to the precise positioning and secure installation of rubber springs. Engineered to meet the rigorous demands of mining and aggregate processing, this assembly ensures the stable operation of vibration-damping systems, effectively protecting screening equipment from excessive impact and extending its service life.
Core Structure
The Support Spring Assembly is designed for durability and functional reliability, comprising key components that work in synergy:
Mounting base: High-strength steel plate or cast iron foundation, providing a stable platform for connecting to the screen's main frame.
Guide Sleeve: Precision-machined steel sleeve that guides the rubber spring, preventing lateral displacement during equipment operation.
Fixing Bolt & Nut: High-tensile steel fasteners with anti-loosening design, ensuring the rubber spring and assembly components remain securely fastened.
Gasket Set: Rubber or metal gaskets that enhance sealing performance and reduce direct friction between components.
Adjustment Washer: Optional thickness-adjustable washers that allow fine-tuning of the rubber spring's installation height to match different screen models.
Key Applications
Exclusively developed for Nanchang Mining's screening equipment, the Support Spring Assembly plays an indispensable role in:
Mining Vibrating Screens: Including primary, secondary, and tertiary screens used for ore separation, providing stable positioning for rubber springs to absorb vibration from screen boxes.
Aggregate Screening Equipment: Such as YA series circular vibrating screens and YK series high-frequency screens, ensuring rubber springs maintain optimal damping performance during the classification of ced stone, sand, and gravel.
Heavy-Duty Screening Systems: Adaptable to large-scale screening equipment in harsh mining environments, where reliable rubber spring installation is critical for equipment stability.
Core Advantages
Precise Positioning: The guide sleeve and mounting base are engineered with tight tolerances, ensuring rubber springs are installed in the correct position to maximize vibration-damping efficiency.
Robust Stability: High-strength materials and anti-loosening fasteners prevent assembly deformation or component detachment under continuous vibration and heavy loads.
Easy Installation & Maintenance: Modular design simplifies the installation and replacement of rubber springs, reducing equipment downtime for maintenance.
Strong Compatibility: Customized to match Nanchang Mining's various screen models, eliminating mismatches between the assembly and rubber springs or screen frames.
Enhanced Equipment Protection: By securing rubber springs in place, the assembly ensures effective vibration absorption, reducing wear on screen bearings, motors, and other core components.
