EP-ET3320 3-Stage Standard Inline Planetary Gearbox
Brevini Riduttori ET3320 Compatible Replacement | EVER POWER
The ET3-series is EVER POWER’s workhorse 3-stage inline planetary gearbox, covering ratio ranges up to 200:1 in a single housing. It serves heavy conveyors, industrial hoists, mixer drives, extruder drives, pump drives and large fan systems where high torque multiplication is needed alongside consistent performance in continuous industrial duty cycles.
The EP-ET3320 replaces the Brevini riduttori ET3320 ?? a 3-stage inline planetary gearbox delivering approximately 92,000 Nm output torque, ratio range 20:1 – 200:1, and IP rating IP66.

مبدأ العمل
Three sequential planetary stages cascade torque multiplication. Stage 1 operates at the highest input speed with smallest module gears; stage 3 operates at the lowest speed with largest module gears and the highest torque. A one-piece forged planet carrier in the output stage eliminates the flex found in welded split-type carriers, ensuring even planet load distribution at peak torque. Oil-bath lubrication supports any mounting orientation without modification.
