NUODUN Gear Reducers Applied in PU Roller Coating Equipment

In PU (polyurethane) roller-coating production lines, precise speed control, uniform torque output, and long-term operational stability are critical to achieving consistent coating thickness and surface quality. NUODUN supplied a customized drive solution integrating multiple geared motor assemblies to ensure smooth and synchronized roller movement across the machine.

Application Details

The pictured PU roller-coating equipment uses multiple NUODUN worm-gear reducers paired with compact geared motors, mounted in parallel to drive individual rollers at controlled speeds. This configuration ensures stable and repeatable coating performance even under continuous industrial duty cycles.

Key Functions Enabled by NUODUN Drives:

• Synchronized multi-roller transmission
  Each roller is driven by an independent geared motor, allowing fine adjustment of coating pressure, speed, and direction.
• High-torque, low-speed output
  Worm-gear reducers deliver smooth, vibration-free motion essential for PU coating uniformity.
• Stable operation under continuous load
  Aluminum housing and precision-ground worm gears ensure low noise and reliable performance during long production runs.
• Compact installation footprint
  The right-angle structure of NUODUN worm-gear units allows dense multi-motor layout without interfering with machine mechanisms.
