Precision Operation Maintains Accurate Positioning The RPG system features an innovative ring gear and roller pinion technology that provides extremely accurate positioning. The Roller Pinion Gear system also offers backlash-free performance in both directions by maintaining opposing contact with two or more teeth at all times.
Patented Tooth Design Ensures Quiet Operation The RPG system is designed with bearing supported rollers that move smoothly 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. Ring gears larger than this become segmented and can be virtually any diameter. Arc segments can also be provided.
Rugged Design Capable of High Speeds The RPG system maintains accurate positioning at peripheral speeds as high as 11 m/sec (36.1 ft/sec). Even at these speeds, the extremely-low friction design does not create heat or wear on components.
