The Planar Spiral Gearbox

Plainly and simply: unrivalled. We are careful in using the word “innovation”. But in this case, it is appropriate. This is because the entire development of the TorusGear system sets new standards: smaller, more efficient, and more variable than any other gearbox in its class. TorusGear can be designed so compact that talking about its “installation space” almost sounds like an exaggeration. And this is combined with a new type of planar spiral gearing, which is designed for high and efficient force transmission through the use of optimal contact geometry. Design engineers are also all delighted:...

TorusGear is not afraid of comparison. Less is more. Much more. Direct comparison with a conventional worm gearbox (left image) clearly illustrates the advantages of TorusGear. Lighter thanks to significant material savings – and simultaneously increased service life. Compact world champion: this significantly reduces the installation space required, and simplifies the shaft bearing. The significantly smaller centre distance is also noteworthy, at 25 mm in the TorusGear compared to 80 mm in the worm gearbox.
