Nexen introduces the Roller Pinion Gear System
Accurate Positioning and Precise Operation The RPG system features nexen's unique roller pinion technology that provides extremely accurate positioning. The Roller Pinion Gear system offers backlash-free transmission in both directions by maintaining at all times opposing contact with two or more teeth.
Patented Tooth Design Ensures Quiet Operation The RPG system is designed with bearing supported rollers which smoothly roll along the face of each tooth. This reduces the noise levels by eliminating tooth slap common to traditional gear systems and chain drives.
Solid and Segmented Ring Gears Provide Easy Integration and Unlimited Diameters Nexen can provide solid ring gears up to one meter in diameter. Larger diameters can also be provided in easy to assemble segments.
Rugged Design Capable of High Speeds The RPG system maintains accurate positioning at peripheral speeds as high as 11 m/sec. Even at these speeds, the extremely-low friction design ensures minimal heat generation or wear on components.
