New gear design is key to power without noise

New gear design is key to power without noise
A cutting-edge coaxial-drive gearhead from Maxon Motor has introduced a revolutionary new style of gearing that produces exceptionally low levels of noise. Uniquely, the Koaxdrive KD 32 utilises both a worm-formed motor pinion and planetary gearing to deliver formidable torque in almost total silence - even with high input loads. 

The real innovation is found in the first gear stage, where the majority of noise is usually produced: here we find three offset wheels, driven by the helical pinion, which interlock with a straight-cut internal gear. Maxon's new, patent-protected use of a sliding mechanism takes axial load off the motor shaft, dramatically reducing contact sound and allowing the gearhead to operate happily, even at speeds of 8000rpm. The planetary gears then provide high reduction rates in a single gearbox, with a number of ratio options available.

Not only does the singular nature of the gearing mechanism mean that noise levels are minimal, but the Koaxdrive also, like other Maxon products, has extremely high output for its small size - up to 6.5Nm of torque with an outer diameter of just 32mm.

The gearhead's unique combination of great power, small size and low noise opens up new possibilities in a wide range of engineering fields. Maxon reports interest already from the luxury car market, where there refinement is always at premium, and the medical industry, where silence in surgical instruments is crucial. 

The new Koaxdrive KD 32 will give the company further impetus in noise-sensitive applications such as these. Paul Williams, senior sales engineer at Maxon Motor UK, says: "Gearing is a very well-established field, and it is highly unusual to find real innovation - but with the Koaxdrive, we've pioneered a genuinely new concept. When I describe this technology to design engineers, their eyes light up. We're giving them the solution to an age-old problem: generating power without noise."
