Deskripsi
EP-EC4030 4-Stage Compact High-Ratio Planetary Gearbox
Brevini Riduttori EC4030 Compatible Replacement | EVER POWER
The EC4-series delivers 4-stage ratio coverage up to 400:1 in EVER POWER’s most compact RPM-series housing ?? targeting applications where both extreme ratio and minimum housing size are simultaneously required. It serves compact winch drives, small tracked machine travel drives, micro-positioning systems, compact industrial hoist units and tight-envelope high-reduction drives that cannot accommodate full-size 4-stage housing dimensions.
The EP-EC4030 replaces the Brevini riduttori EC4030 ?? a 4-stage compact planetary gearbox delivering approximately 4,200 Nm output torque, ratio range 30:1 – 400:1, and IP rating IP65.
Technical Parameters
| Parameter | Value |
|---|---|
| Model | EP-EC4030 |
| Replaces | Brevini riduttori EC4030 |
| Output Torque | 4,200 Nm |
| Gear Stages | 4 |
| Ratio Range | 30:1 – 400:1 |
| Max Input Speed | 3,000 rpm |
| Efficiency | >= 92% |
| Protection Class | IP65 |
| Approx. Weight | ~26 kg |
Working Principle
Four planetary stages are packed coaxially in the compact housing using thin-wall ring gear sections and optimised planet-to-ring gear clearance. The output shaft features a large-diameter bore option allowing a hollow-through shaft configuration ?? enabling the EC4 to be mounted directly on a drive shaft or screw without a separate shaft-to-shaft coupling, which is especially valuable in very compact installations.
Core Advantages
|
★ Up to 400:1 Compact
4-stage reduction in smallest available housing diameter. |
★ Hollow Through-Shaft Option
Mount directly on drive screw or shaft ?? eliminates coupling. |
|
★ Thin-Wall Ring Construction
Maximum torque density in minimum radial space. |
★ Compact High-Ratio
Replaces tandem gearbox arrangements in space-constrained machines. |
|
★ Direct EC4-Series Replacement
Same mounting pattern as original Brevini unit. |
Structure and Material Technology
Thin-wall ring gear sections are machined from 42CrMo4 through-hardened steel for maximum stiffness in the reduced wall thickness. Planet gears use 17CrNiMo6 carburised steel, ground to DIN 5. The hollow through-shaft option uses a precision-ground bore to H6 tolerance for interference or clearance fit on the drive shaft. Seals are FKM fluoroelastomer for synthetic oil.
Typical Application Scenarios
| Industry | Application | Key Benefit |
|---|---|---|
| Food | Portioning conveyor drive | IP65 sealing for food-grade wash-down compliance. |
| Packaging | Carton erector drive | Reliable high-cycle servo drive for carton forming. |
| Textile | Yarn winding tension drive | Precise speed regulation for consistent winding tension. |
| Automation | Guided vehicle wheel drive | Compact housing for narrow-profile AGV wheel assemblies. |
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 ?? 4-stage (4-stage compact) provides ratio 30:1 – 400:1.
- Motor Interface ?? Flange type (SAE/ISO metric), shaft diameter and key.
- Operating Environment ?? IP class, ambient temperature, mounting orientation.

Frequently Asked Questions
Q: What applications benefit most from the hollow through-shaft option?
A: Ball screw drives, spindle through-feeds and cable management channels that must pass through the gearbox centre benefit most. The hollow bore eliminates the need for a separate coupling.
Q: Is the EC4 available with a brake flange?
A: Yes. An input-side spring-applied brake interface boss is available for compact hoisting and winching applications.
