Rubber Chock
Overview
The Triangular Rubber Buffer is a specialized mechanical component designed to absorb shocks, dampen vibrations, and protect equipment from impact damage. Its triangular shape provides stability and even force distribution, making it suitable for various industrial applications. These buffers are commonly used in construction machinery, transportation equipment, and manufacturing systems where impact forces need to be mitigated. The rubber construction offers both flexibility and durability, ensuring long-term performance under repetitive loading conditions.
Structure and Working Principle
The Triangular Rubber Buffer typically consists of a solid rubber body molded into a triangular prism shape, often with mounting holes or grooves for secure installation. The geometry provides multiple contact surfaces for effective energy absorption. When subjected to impact, the rubber compresses elastically, converting kinetic energy into heat through internal friction. The triangular design helps distribute forces evenly across all sides, preventing localized stress concentrations that could lead to premature failure.
Key Features
Triangular Rubber Buffers offer several advantages including excellent shock absorption capabilities, with energy dissipation rates typically ranging from 60-80% depending on the rubber compound used. They provide vibration isolation, reducing noise transmission by up to 30 dB in many applications. The natural resilience of rubber allows these buffers to return to their original shape after deformation, ensuring consistent performance over thousands of cycles. Special formulations can include additives for UV resistance, ozone protection, or enhanced temperature tolerance.
Application Areas
These buffers find widespread use in industrial machinery as vibration isolators under heavy equipment like presses, compressors, and generators. In construction, they're installed in bridge expansion joints and as seismic buffers in buildings. Transportation applications include railcar couplings, truck suspension systems, and dock bumpers. They're also employed in material handling equipment, conveyor systems, and as anti-vibration mounts for sensitive laboratory or medical equipment.
Maintenance and Precautions
Regular inspection should check for signs of cracking, permanent deformation, or surface degradation. Most buffers last 5-10 years under normal conditions but may require replacement sooner in harsh environments. Avoid using petroleum-based cleaners or exposing the buffers to solvents that could degrade the rubber. Temperature limits typically range from -40°C to +80°C for standard compounds, with specialty materials available for more extreme conditions.
B2B Procurement Guide
When sourcing Triangular Rubber Buffers, specify the required load capacity (static and dynamic), dimensions, and any special environmental requirements. Lead times for standard sizes are typically 2-4 weeks, with MOQs varying by supplier. Quality indicators include Shore hardness (usually 50-80 Shore A), compression set values (<25% after 24 hours at 70°C), and tear resistance (>20 N/mm). Certifications to look for include ISO 9001, ROHS compliance, and industry-specific standards like DIN or ASTM.
