Deskripsi
EP-EQ4155 4-Stage Ultra-High Ratio Planetary Gearbox
Brevini Riduttori EQ4155 Compatible Replacement | EVER POWER
Itu EQ4-series 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 where output speed is measured in RPM fractions and maximum torque is non-negotiable.
Itu EP-EQ4155 menggantikan riduttori Brevini EQ4155 ?? a 4-stage planetary gearbox delivering approximately 59,500 Nm output torque, ratio range 50:1 – 500:1, and IP rating IP66.

Prinsip Kerja
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 ?? 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.
Keunggulan Utama
|
● Up to 500:1 Single Housing
Eliminates tandem gearbox arrangements for extreme ratios. |
● Dual-Seal Output Shaft
Primary FKM seal plus labyrinth ?? redundant ingress protection. |
|
● IP66 Standard Sealing
Outdoor and wet industrial environment rated. |
● 4-Stage Torque Density
Maximum torque for given housing size in the EC/EM range. |
|
● Direct EQ4-Series Replacement
Identical flange and port dimensions. |
Teknologi Struktur dan Material
All four stages use 17CrNiMo6 carburised and ground steel gears. Output stage planet journals run on needle roller bearings with hardened pins for maximum radial stiffness. The housing is cast from Besi cor ulet GGG50 with H7 bore tolerances throughout. External coating is epoxy-chromate primer for C4 corrosion zone service.

Pertanyaan yang Sering Diajukan
Q: What is the minimum output speed achievable?
A: With a 3,000 rpm input and the 500:1 maximum ratio, minimum output speed is 6 rpm. Lower speeds require a proportional reduction in input speed.
Q: Can the EQ4-series handle reversing loads?
A: Yes. All four stages are rated for equal forward and reverse torque. Fatigue life calculations assume 50/50 direction split.
