EP-RPR3046 Planetary Gearbox
EVER POWER 3-Stage Compact Planetary Gearbox ?? Higher Reduction for Automation
De EP-RPR3046 adds a third planetary stage to the RPR046 housing, raising peak output torque to 7,800 Nm and ratio range to 100:1 while maintaining the same external footprint as the 2-stage RPR2046. This makes it the first choice when servo or induction motors need a high reduction ratio ?? such as slow-speed rotary tables, indexing mechanisms and material handling lifts ?? without enlarging the machine frame.

Werkingsprincipe
Three sequential planetary stages share the same concentric axis. Stage 1 handles the high-speed motor input at up to 3,500 rpm. Stage 2 and 3 multiply torque further with each reducing input speed proportionally. The floating sun gear in stage 2 compensates for carrier concentricity errors between stages, eliminating the need for precision alignment at assembly and improving load sharing across all planet gears simultaneously.
Kernvoordelen
|
▲ 100:1 High Ratio
3-stage design covers slow-speed applications that a 2-stage cannot reach. |
▲ Same Footprint as RPR2046
No machine redesign needed when upgrading from 2-stage to 3-stage. |
|
▲ Floating Sun Stage 2
Compensates inter-stage concentricity, improving load sharing and life. |
▲ Angular Contact Output
Handles combined axial and radial loads from cantilevered drive elements. |
|
▲ Direct RPR3046 Replacement
Identical flange dimensions ?? bolt-in replacement. |
Structuur- en materiaaltechnologie
The 3-stage housing is cast from GGG40 ductile iron for stiffness. Planet gears throughout all three stages use 17CrNiMo6 steel, carburised and ground to DIN 5 accuracy. Angular contact ball bearings support the output shaft, providing combined axial and radial load capacity for cantilevered gear or sprocket loads.
Typische toepassingsscenario's
| Industrie | Sollicitatie | Key Requirement |
|---|---|---|
| Automatisering | Slow-speed rotary table drive | 100:1 ratio provides smooth, precise table rotation from a standard motor. |
| Materiaalbehandeling | Goods lift / vertical conveyor | High reduction allows small motor to drive heavy loads at low speed. |
| Afdrukken | Web-spanningsregeling danser rol | 3-stage accuracy maintains consistent web tension across print width. |
| Voedselverwerking | Mixing and dosing conveyor | IP65 sealing handles food-grade wash-down on external surfaces. |
Selectiegids
- Vereist uitgangskoppel (Nm) ?? Confirm peak and continuous torque requirement with appropriate safety factor.
- Overbrengingsverhouding ?? Motor speed (rpm) divided by required output speed (rpm).
- Duty Cycle ?? Continuous S1 or intermittent S3/S6; affects thermal de-rating.
- Motorinterface ?? Flange type (SAE/ISO), shaft diameter, keyway or spline specification.
- Environment ?? IP class, ambient temperature, corrosion zone, orientation.

Veelgestelde vragen
Q: What is the efficiency of the 3-stage design?
A: Each stage has >= 96% efficiency. Three stages combined: >= 88.5% overall. This is suitable for most continuous industrial duty applications.
Q: Can I use the same motor as my existing RPR2046 installation?
A: Yes, provided the motor speed and torque are within the EP-RPR3046 input rating. The input flange dimensions match the RPR2046 family.
