EP-EC2320 2-Stage Compact Planetary Gearbox
Brevini Riduttori EC2320 Compatible Replacement | EVER POWER
The EC2-series delivers the efficiency and ratio range of a 2-stage planetary design in a radially compact housing specifically engineered for tight-envelope OEM installations. The reduced housing diameter versus the ED2-series makes EC2 units the first choice for motor-integrated drives, AGV wheel hubs, linear actuator heads, robot joint drives and space-constrained automation equipment.
The EP-EC2320 replaces the Brevini riduttori EC2320 ?? a 2-stage compact planetary gearbox delivering approximately 43,700 Nm output torque, ratio range 8:1 – 40:1, and IP rating IP65.
Technical Parameters
| Parameter | Value |
|---|---|
| Model | EP-EC2320 |
| Replaces | Brevini riduttori EC2320 |
| Output Torque | 43,700 Nm |
| Gear Stages | 2 |
| Ratio Range | 8:1 – 40:1 |
| Max Input Speed | 5,000 rpm |
| Efficiency | >= 96% |
| Protection Class | IP65 |

Working Principle
The compact design uses a thin-ring construction ?? the ring gear bore and housing outer diameter are minimised through careful gear module selection, reducing the housing diameter by up to 15% versus the standard ED2 series at the same torque rating. Both stages use needle-roller planet journals for maximum radial stiffness in the reduced-diameter housing, maintaining planet-to-ring gear mesh accuracy under cantilevered load conditions.
Core Advantages
|
◆ Compact Radial Envelope
Up to 15% smaller OD vs ED2 ?? fits tight machine bores and hubs. |
◆ Needle Roller Planet Journals
Maximum planet radial stiffness in thin-ring housing. |
|
◆ Motor-Integration Compatible
Short axial length suits motor-gearbox integrated units. |
◆ 5,000 rpm High Input Speed
Servo and high-speed motor compatibility. |
|
◆ Direct EC2-Series Replacement
Same mounting dimensions as Brevini original. |
Structure and Material Technology
Housing is machined from 7075 aluminium alloy or GGG50 iron depending on size. Planet gears use 20CrMnTi carburised steel, ground to DIN 6. Thin-ring construction requires press-fit ring gear installation with Loctite 638 retaining compound for permanent bore fixation. Output shaft seals are double-lip NBR for dust and oil retention in compact housings.
Typical Application Scenarios
| Industry | Application | Key Benefit |
|---|---|---|
| Cement | Giant grinding mill main drive | Class-leading torque for the largest cement mill installations. |
| Steel | Primary metal reduction drive | Extreme duty cycle for continuous primary slab rolling. |
| Mining | Very large SAG/ball mill drive | Maximum torque for the largest mineral processing mills. |
| Marine | Large ship propulsion gearbox | High power transmission for large vessel main propulsion. |
Selection Guide
