Synchronizing the “Veluwe” Paper Valley<\/h2>\n
\n
\n

The Challenge of Continuous Speed<\/h3>\n

The Netherlands maintains its position as a global leader in high-quality graphical and packaging paper through relentless efficiency. In the paper clusters of **Eerbeek** and **Renkum**, modern machines operate at speeds exceeding 2,000 meters per minute. At these velocities, the sectional drive shafts connecting the motors to the dryer cylinders, calenders, and wire rolls become the most critical components for product quality.<\/p>\n

The primary enemy is **resonance**. As machine speeds increase, standard cardan shafts often approach their lateral critical speed, inducing vibrations that transfer to the paper web. This phenomenon, known as “barring,” creates periodic thickness variations that ruin paper quality. Furthermore, the environmental disparity\u2014100% humidity in the Wet End versus 120\u00b0C heat in the Dryer Section\u2014demands a “Dual-Strategy” approach to sealing and lubrication that generic industrial shafts cannot provide.<\/p>\n<\/div>\n

\n

The Ever-Power “PM-Velocity” Solution<\/h3>\n

Ever-Power has introduced the **PM-Velocity\u2122 Series** to meet the specific demands of the Dutch paper industry. We utilize large-diameter, thin-wall tubes made from high-modulus steel (or optional Carbon Fiber composites) to push the critical speed threshold well above the machine’s operating range. This ensures vibration-free transmission even at 3,000 RPM.<\/p>\n

For the Wet End, our shafts feature **AISI 316L Stainless Steel** flingers and triple-lip Viton sealing to prevent water ingress. For the Dryer Section, we employ a high-temp thermal expansion compensation spline coated with Molybdenum Disulfide to prevent “stick-slip” during thermal cycling. Our adherence to **NEN-EN 13001** and ISO 12100 standards guarantees that our shafts contribute to the overall safety and uptime of the mill.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Systemic Synergy: Gearbox Integration<\/h3>\n

A paper machine sectional drive is a complex ecosystem. The motor connects to the gearbox, which drives the roll via the cardan shaft. Any misalignment or vibration in the shaft transmits directly to the gearbox output bearings. We recommend pairing our **PM-Velocity Shafts** with **Ever-Power Precision Paper Mill Gearboxes**.<\/p>\n

Our gearboxes feature specialized output shafts designed to handle the axial thermal expansion forces transmitted by the cardan shaft. For the Dutch market, we offer “System Tuning” \u2013 analyzing the torsional vibration of the entire drivetrain (Motor-Gearbox-Shaft-Roll) to ensure resonance-free operation at target speeds.<\/p>\n

Case Study: Eerbeek Board Mill<\/span><\/p>\n

Eliminating “Dryer Barring” in Board Production<\/h3>\n

The Challenge:<\/strong> A leading folding boxboard producer in Eerbeek was suffering from “barring marks” (periodic thickness variations) on their PM3 machine. Vibration analysis pinpointed the drive shafts on the 4th Dryer Group. The existing shafts were operating too close to their lateral critical speed, causing resonance at 900 m\/min.<\/p>\n

The Ever-Power Solution:<\/strong> We replaced the standard 120mm diameter shafts with our PM-Velocity 150 Series<\/em> (150mm High-Modulus Tube). This stiffened the drives, shifting the natural frequency to 1400 m\/min, well outside the operating range. We also used our “Thermal-Comp” splines to absorb the 15mm expansion of the steam-heated cylinders.<\/p>\n

The Impact:<\/strong> The barring marks disappeared immediately. Machine speed was increased by 8% without vibration issues, resulting in an additional 4,000 tons of production per year, valued at over \u20ac350,000<\/strong>.<\/p>\n<\/div>\n

Expert Insights: FAQ for Dutch Mill Engineers<\/h3>\n
\n

How do you prevent vibration in long paper machine drive shafts?<\/h4>\n
\n

Vibration usually stems from operating too close to the critical speed. We solve this by using **High-Modulus Steel** or **Carbon Fiber Composite** tubes with larger diameters to increase stiffness. This pushes the critical speed resonance well above the machine’s operating RPM. We also balance every shaft to ISO Grade G2.5.<\/p>\n<\/div>\n<\/div>\n

\n

What is the delivery time for a replacement shaft to a mill in Limburg?<\/h4>\n
\n

We prioritize the Dutch paper sector. For standard DIN flange sizes (e.g., replacing Voith or GWB units), we can manufacture and air-freight a balanced, painted shaft to Maastricht or Eindhoven within 4-5 weeks. Emergency 10-day manufacturing is available for breakdown situations.<\/p>\n<\/div>\n<\/div>\n

\n

Can your shafts handle the heat in the dryer section?<\/h4>\n
\n

Yes. Our Dryer Section shafts are equipped with **Viton (FKM) Seals** rated for 200\u00b0C and lubricated with High-Temp Synthetic Complex grease. Crucially, our “Thermal-Comp” splines are designed to accommodate the axial expansion of the drying cylinders without locking up.<\/p>\n<\/div>\n<\/div>\n

\n

Are your products compatible with Dutch NEN-EN safety standards?<\/h4>\n
\n

Absolutely. Every Ever-Power shaft is engineered with a Safety Factor >2.0 for continuous operation, complying with **NEN-EN 13001** and the **Machinery Directive 2006\/42\/EC**. We provide full technical documentation to support your mill’s safety audits.<\/p>\n<\/div>\n<\/div>\n
