If substantial growth returns to this sector, it will stimulate a sharp demand once again for precision gearboxes and geared motors. Two key technologies in this segment are: n Coaxial cycloidal precision gearboxes These comprise an input shaft, an eccentrically mounted bearing, a cycloidal disc (or discs), ring pins and output rollers and shafts. Examples include Nabtesco’s RDSE and Spinea’s TS series. n Coaxial strainwave precision gearboxes These comprise a rigid circular spline, exible internal spline and wave generator, and are also known as harmonic gearboxes. Examples include Harmonic Drive’s CSG-2UH and Nidec’s Flexwave boxes. Although demand for precision geared products remains tightly aligned with the industrial robotics industry, it is clear that mobile robots currently oer the largest growth potential for these technologies. Companies active in the planetary gearbox market are likely to benet most from this because these are the main type of gearbox used in mobile robots. One nal thought is this: if humanoid robots nd a place in industry, they could also become a signicant driver of growth in demand for precision gearboxes. Even the simplest humanoid robots would probably need a minimum of around 30 precision gearboxes, although some humanoid robots currently being developed are said to need closer to 80 precision gearboxes. Which products will be best suited for this application and which suppliers will succeed in this market remains to be seen. n Data on the precision gearbox and geared motors market is available in Interact’s updated Precision Gearboxes & Geared Motors – 2024 report, which was published recently. www.interactanalysis.com Precision gearbox and geared motors are bene tting from a growth in the adoption of mobile robots Small and precise (from left to right): Harmonic Drive’s strainwave gearbox; Nabtesco’s cycloidal gearbox; and Stober’s planetary gearbox
