EP-ED2045 2-Stage Standard Inline Planetary Gearbox
Brevini Riduttori ED2045 Compatible Replacement | EVER POWER
The ED2-series delivers a balanced combination of ratio range, efficiency and compactness in a 2-stage inline planetary configuration. With ratio coverage of 10:1 to 50:1 and input speeds to 5,000 rpm, it serves industrial automation, packaging machines, conveyor drives, printing presses and medium-duty machine tool axes where efficiency and moderate reduction are simultaneously required.
The EP-ED2045 replaces the Brevini riduttori ED2045 ?? a 2-stage inline planetary gearbox delivering approximately 2,640 Nm output torque, ratio range 10:1 – 50:1, and IP rating IP65.
Technical Parameters
| Parameter | Value |
|---|---|
| Model | EP-ED2045 |
| Replaces | Brevini riduttori ED2045 |
| Output Torque | 2,640 Nm |
| Gear Stages | 2 |
| Ratio Range | 10:1 – 50:1 |

Working Principle
The first stage sun gear accepts motor input. Its planet carrier becomes the second-stage sun shaft, compounding the reduction. A floating sun gear between stages automatically centres the load distribution across all planet contacts, compensating for minor bore concentricity errors and extending planet bearing life in high-cycle automation duty. Both stages share a single oil sump for maintenance-free lubrication across the rated service interval.
Core Advantages
|
▲ 10:1 – 50:1 Ratio Range
Wide 2-stage coverage from one product family. |
▲ Floating Inter-Stage Sun
Self-equalises planet loads ?? extends life in high-cycle duty. |
|
▲ 5,000 rpm Input
High input speed for direct servo or VFD motor coupling. |
▲ Shared Sump Lubrication
Maintenance-free service across both stages. |
|
▲ Direct ED2-Series Replacement
Same mounting interface as Brevini original. |
Structure and Material Technology
Housing cast from GGG50 ductile iron. Planet gears use 17CrNiMo6 carburised steel, ground to DIN 5. The output shaft is supported by a back-to-back angular contact bearing pair, pre-loaded to eliminate axial play under reversing loads. External seals are NBR compound for mineral and synthetic oil compatibility.
Typical Application Scenarios
| Industry | Application | Key Benefit |
|---|---|---|
| Machine Tool | Servo turret indexing | Low backlash for repeatable tool position on CNC lathe. |
| Packaging | Stretch wrapping machine | Consistent film pre-stretch ratio from servo drive. |
| Medical | Surgical robot joint | Minimum backlash and smooth torque for safe patient contact. |
| Printing | Print drum speed control | Precise speed for registration accuracy in multi-colour print. |
Selection Guide
- Required Output Torque (Nm) ?? Confirm peak and continuous with safety factor (1.3-2.0 typical).
- Gear Ratio ?? Motor speed (rpm) / required output speed (rpm).
- Stage Count ?? 2-stage (2-stage inline) provides ratio 10:1 – 50:1.
- Motor Interface ?? Flange type (SAE/ISO metric), shaft diameter and key.
- Operating Environment ?? IP class, ambient temperature, mounting orientation.

Frequently Asked Questions
Q: Can the ED2-series be used with a VFD (variable frequency drive)?
A: Yes. The 5,000 rpm rated input speed accommodates VFD output at standard and boost frequencies. Confirm maximum continuous motor current for thermal sizing.
Q: What is the minimum oil change interval?
A: With synthetic ISO VG 220 oil, first change at 500 hours then every 2,500 hours or 12 months, whichever comes first.
