EP-RPR2046 Planetary Gearbox
EVER POWER Compact 2-Stage Planetary Gearbox for Light Industrial Automation
The EP-RPR2046 is EVER POWER’s lightest RPR series planetary gearbox, engineered as a direct replacement for the Brevini riduttori RPR2046. At 4,600 Nm and only 18 kg, it serves industrial automation, packaging machinery, conveyor drives and light robotic articulation where space, weight and positioning accuracy are the primary design constraints.
Technical Parameters
| Parameter | Value |
|---|---|
| Model | EP-RPR2046 |
| Replaces | Brevini riduttori RPR2046 |
| Max Output Torque | 4,600 Nm |
| Gear Stages | 2 |
| Ratio Range | 16:1 – 60:1 |
| Max Input Speed | 4,000 rpm |
| Protection Class | IP65 |
| Approx. Weight | ~18 kg |
Working Principle
Input torque enters via the motor flange and drives a first-stage sun gear. Planet gears orbit the sun and react against a fixed ring gear, multiplying torque at the first-stage carrier. The carrier becomes the second-stage input, providing cumulative ratio up to 60:1. The needle-roller planet journals maintain precise planet positioning at high input speeds, critical for servo-motor compatibility.
Core Advantages
|
● Lightweight 18 kg
Aluminium housing option keeps vehicle and machine weight minimal. |
● 4,000 rpm Input
High input speed compatibility for servo and high-speed induction motors. |
|
● Low Backlash
Needle-roller planet journals minimise backlash for precise servo positioning. |
● IP65 Sealing
Dust-tight and splash-proof for indoor automation environments. |
|
● Direct RPR2046 Fit
Same flange and output bore ?? no machine modification at retrofit. |
Structure and Material Technology
Housing cast from ADC12 aluminium alloy for minimum weight. Planet gears use 20CrMnTi steel carburised to 0.6-0.8 mm, ground to DIN 6 accuracy. All seals are NBR compound for synthetic and mineral gear oil compatibility.
Typical Application Scenarios
| Industry | Application | Key Requirement |
|---|---|---|
| Automation | Conveyor indexing drive | Low backlash ensures accurate package positioning at high cycle rate. |
| Packaging | Servo-driven sealing jaw | High input speed (4,000 rpm) compatible with servo motor for fast jaw cycle. |
| Material Handling | Light AGV wheel drive | Compact aluminium housing minimises vehicle weight and extends battery range. |
| Robotics | Arm rotation joint | Low backlash required for repeatable arm positioning. |
Selection Guide
- Required Output Torque (Nm) ?? Confirm peak and continuous torque requirement with appropriate safety factor.
- Gear Ratio ?? Motor speed (rpm) divided by required output speed (rpm).
- Duty Cycle ?? Continuous S1 or intermittent S3/S6; affects thermal de-rating.
- Motor Interface ?? Flange type (SAE/ISO), shaft diameter, keyway or spline specification.
- Environment ?? IP class, ambient temperature, corrosion zone, orientation.

Frequently Asked Questions
Q: Is the EP-RPR2046 servo-motor compatible?
A: Yes. The high input speed rating (4,000 rpm) and low backlash are compatible with standard servo motor specifications. Confirm encoder feedback cable routing with your machine designer.
Q: What is the backlash specification?
A: Standard backlash is <= 8 arcmin. A reduced-backlash option (<= 5 arcmin) is available for high-precision servo applications ?? specify at order.
