The Koaxdrive KD 32 combines the best of two proven gearing technologies, namely worm and planetary gearing. Special attention has been focused on the first gear stage, as this is where the greatest peripheral speeds occur and therefore noise. The patent-protected design has enabled the substantial reduction of this noise. The worm-formed motor pinion drives the three offset planetary wheels interlocking with the internal gear, which has straight cut teeth. The plastic planetary wheels are largely responsible for reducing noise levels. All additional stages are set out as a completely "normal" straight-cut planetary gearhead. This unique torque conversion makes operation very quieteven with high loads.
