Product Description
S2M Timing Pulley is a precision synchronous pulley designed specifically for lightweight and cost-effective transmission scenarios, suitable for low to medium load fields such as office automation, medical equipment, 3C electronics, and food packaging. With compact design, precise meshing, and cost advantages It can support efficient operation of small and medium-sized devices (with a maximum speed of 8000 RPM), significantly reducing equipment maintenance costs, and is the preferred transmission component for upgrading smart factories and lightweight machinery.
Production process flow
Material selection and inspection
Material: 6061-T6 aluminum alloy (main body)/SUS304 stainless steel (rust proof version)/nylon PA66 (insulation version).
Inspection: Material hardness testing (HB ≥ 90), chemical composition analysis (spectrometer) to ensure compliance with ROHS/REACH standards.
Mold Design and Manufacturing
Tooth shaped mold: designed based on ISO Level 5 standard, carved using a five axis CNC machining center with a tolerance of ± 0.005mm.
Heat treatment: Aluminum alloy molds undergo solid solution aging treatment to improve wear resistance (surface hardness HV ≥ 120).
Precision machining
CNC turning: Use DMG MORI five axis machine tool to machine the wheel body, ensuring concentricity ≤ 0.008mm.
Tooth groove grinding: laser positioning+CBN grinding wheel precision grinding is used, with a tooth symmetry error of less than 0.003mm.
Surface treatment
Anodizing (aluminum alloy): thickness 10-15 μ m, hardness HV ≥ 150, corrosion resistance increased by 3 times.
Nickel plating (stainless steel): thickness 3-5 μ m, passed ASTM B733 salt spray test (48 hours).
Teflon coating (nylon): reduces friction coefficient to 0.08, suitable for high-speed and low-noise scenarios.
Quality inspection
Three coordinate measurement: detect tooth profile accuracy, aperture concentricity, and import data into MES system for traceability.
Dynamic balance test: Vibration value ≤ 2.5mm/s at a speed of 1500 RPM, certified by CE.
Packaging and Delivery
Rust proof packaging: vacuum sealed+desiccant, supports DHL/FedEx global delivery within 72 hours.
Differentiated selling points
Lightweight design: The aluminum alloy version has a density of 2.7g/cm ³ and is 40% lighter than the stainless steel version, making it suitable for portable devices such as medical robots.
Intelligent noise reduction: with involute tooth tip rounded corner design, the noise is ≤ 50dB (A), which is 5-8dB lower than competitors.
Flexible adaptation: Supports MXL/XL/L/H/S2M multi series tooth compatibility, reducing customer inventory pressure.
