ETA-Drive

Product concept

These gear units combine the advantages of worm gear units with those of spur gear units: In the first gear high revs range, the multiple worm shafts run at efficiencies of up to 95% at lubrication favourable gear unit ratios. Here, the worm gear stages have optimum vibration damping properties that provide optimized smooth running.
Noise-optimized spur gear sets run in the downstream second or third gear reduction stages with equally good efficiency at lower speeds.
