Conveyor chain with side roller

The Conveyor chains with side-roller is a transmission system that enables speed
differentiation control between conveyed materials and the chain through its
roller mechanism. The core design principle lies in the ratio between roller
diameter and roller diameter. Taking the speed multiplier chain developed by
Hangzhou Donghua Chain Group as an example, its roller diameter D is typically
2-3 times the roller diameter d. By applying the formula v = v₀ × (D/d), this
configuration achieves a speed multiplier relationship between the worktable
plate movement speed v and the chain's base speed v₀. This design allows the
chain to maintain constant operating speed while flexibly adjusting material
delivery rhythms, making it particularly suitable for dynamic adjustment
scenarios such as logistics sorting and assembly lines.

In the logistics sector, Zhejiang Shenlong Chain Drive's patented dual-row
free-wheel chain technology demonstrates remarkable advantages. Featuring a
dual-row roller structure, this innovation uses motor-driven rotating rods to
engage gears with the chain. Compared to traditional belt drives, it reduces
elastic slip rate to below 0.5% while boosting transmission efficiency by
15%-20%. Field tests show a 30% reduction in axial load when handling 500kg
loads, with bearing lifespan extending by 200%. The system also incorporates a
visual measurement system using 3D cameras mounted on the chain's top, achieving
cargo volume accuracy within 0.2% – a fourfold improvement over traditional
manual measurement methods.

The free-wheel chain delivers three key technical advantages: First, its
anti-static design ensures surface resistance ≤10⁶Ω, meeting ESD protection
standards for electronics workshops. Second, noise control technology reduces
operating noise to below 65dB, 20% lower than conventional chains. Third, the
modular structure enables rapid replacement, with single-section chain
replacement time shortened to 5 minutes. For maintenance convenience, the
self-lubricating sleeve design extends service intervals to 2000 hours through a
lubrication-free mechanism.
