EP-ET3320 3-Stage Standard Inline Planetary Gearbox<\/h1>\n

Brevini Riduttori ET3320 Compatible Replacement | EVER POWER<\/p>\n

The ET3-series<\/strong> 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<\/strong> where high torque multiplication is needed alongside consistent performance in continuous industrial duty cycles.<\/p>\n

The EP-ET3320<\/strong> replaces the Brevini riduttori ET3320<\/strong> ?? a 3-stage inline planetary gearbox delivering approximately 92,000 Nm<\/strong> output torque, ratio range 20:1 – 200:1, and IP rating IP66.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

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<\/strong> in the output stage eliminates the flex found in welded split-type carriers, ensuring even planet load distribution at peak torque. Oil-bath lubrication<\/strong> supports any mounting orientation without modification.<\/p>\n

Structure and Material Technology<\/h2>\n

\"EVER<\/p>\n

Output stage gears use 17CrNiMo6 or 18CrNiMo7-6 carburised steel<\/strong> depending on size, ground to DIN 5. Forged one-piece planet carriers are GGG50 nodular iron<\/strong>. Housing exterior carries epoxy primer + polyurethane topcoat<\/strong> (480h salt spray). Seals are FKM fluoroelastomer<\/strong> for synthetic oil at up to 120 degC.<\/p>\n
