Maxon Motor has introduced a coaxial-drive gearhead that produces exceptionally low levels of noise.

The Koaxdrive KD 32 utilises both a worm-formed motor pinion and planetary gearing to deliver torque in almost total silence, even with high-input loads.

In the first gear stage, where the majority of noise is usually produced, three offset wheels, driven by the helical pinion, interlock with a straight-cut internal gear.

Maxon’s patent-protected use of a sliding mechanism takes axial load off the motor shaft, reducing contact sound and allowing the gearhead to operate well, even at speeds of 8,000rpm.

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 has high output for its small size – up to 6.5Nm of torque with an outer diameter of 32mm.

The combination of power, small size and low noise make the gearhead suitable for a range of engineering fields.

Already showing interest are the luxury-car industry, where refinement is at a premium, and the medical sector, where silence in surgical instruments is crucial.
