EP-EQ4045 4-Stage Ultra-High Ratio Planetary Gearbox<\/h1>\n

Brevini Riduttori EQ4045 Compatible Replacement | EVER POWER<\/p>\n

The EQ4-series<\/strong> achieves ratio ranges up to 500:1 in a single housing by stacking four planetary stages ?? the highest reduction option in the EC\/EM family. Designed for very slow-speed drives, large industrial positioning systems, antenna and telescope slew drives, kiln and furnace car drives, and large-scale material handling applications<\/strong> where output speed is measured in RPM fractions and maximum torque is non-negotiable.<\/p>\n

The EP-EQ4045<\/strong> replaces the Brevini riduttori EQ4045<\/strong> ?? a 4-stage planetary gearbox delivering approximately 8,400 Nm<\/strong> output torque, ratio range 50:1 – 500:1, and IP rating IP66.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

Four coaxial planetary stages cascade speed reduction and torque multiplication. Stage 1 handles the high-speed motor input; each successive stage multiplies torque while halving speed. The 4-stage design uses a dual-seal output shaft arrangement<\/strong> ?? a primary FKM lip seal plus a labyrinth ?? providing redundant protection against dust and slurry ingress in the slow-speed, high-torque industrial environments where EQ4 units are most commonly deployed.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n

Structure and Material Technology<\/h2>\n

\"EVER<\/p>\n

All four stages use 17CrNiMo6 carburised and ground steel<\/strong> gears. Output stage planet journals run on needle roller bearings<\/strong> with hardened pins for maximum radial stiffness. The housing is cast from GGG50 ductile iron<\/strong> with H7 bore tolerances throughout. External coating is epoxy-chromate primer<\/strong> for C4 corrosion zone service.<\/p>\n
