EP-PR3065 Planetary Gearbox
EVER POWER 3-Stage Helical Planetary Gearbox ?? High Reduction for Precision Drives
El EP-PR3065 is EVER POWER’s 3-stage replacement for the Brevini riduttori PR3065. Combining a helical first and second stage with a straight-cut output stage, this unit achieves 11,000 Nm output torque with a ratio range extending to 120:1 ?? covering slow-speed servo applications that a 2-stage unit cannot reach. Targeted at precision machine tools, semiconductor handling equipment, film winding systems and medical imaging drives.

Parámetros técnicos
| Parámetro | Valor |
|---|---|
| Modelo | EP-PR3065 |
| Reemplaza | Brevini riduttori PR3065 |
| Par máximo de salida | 11,000 Nm |
| Etapas de engranajes | 3 |
| Rango de relación | 25:1 – 120:1 |

Principio de funcionamiento

The first two helical stages reduce speed and amplify torque with minimal audible noise. The third straight-cut stage provides maximum torque density for the output. Pre-loaded angular contact bearing pairs on the input and output shafts eliminate axial play under reversal loads, which is critical for servo-driven applications that frequently change direction at high cycle rates.
Ventajas principales
|
● ISO Class 4 Gear Accuracy
Highest accuracy in EVER POWER’s RPR range ?? minimum transmission error for precision axes. |
● Pre-Loaded P4 Bearings
Zero axial play under reversal ?? critical for high-cycle servo applications. |
|
● Helical Stages 1 and 2
Two helical stages provide very low noise ?? suitable for medical and clean-room environments. |
● 120:1 High Ratio
3-stage design covers very slow speed applications without large motor. |
|
● Direct PR3065 Replacement
Matching flange pattern ?? direct bolt-in fit. |
Estructura y tecnología de materiales

All three stage housings are precision-bored from a single GGG50 ductile iron casting, ensuring perfect stage-to-stage axis alignment without separate alignment shims. Input and output shaft bearings are pre-loaded P4 accuracy angular contact pairs. Internal gear flanks are ground to ISO accuracy class 4 ?? the highest standard in EVER POWER’s RPR catalogue ?? for applications demanding minimum transmission error.
Escenarios de aplicación típicos
| Industria | Solicitud | Requisito clave |
|---|---|---|
| Semiconductor | Wafer handler rotation axis | ISO class 4 gear accuracy meets nanometre-level positioning requirements. |
| Medical | MRI table positioning drive | Ultra-low noise from helical stages is essential in quiet scan room environments. |
| Film / Foil | Precision winding tension control | Pre-loaded bearings prevent axial play under frequent tension reversal. |
| Optics | Telescope or antenna slew drive | 120:1 ratio provides very slow precise angular movement from standard motor. |

Estudios de caso ?? Notas de campo del ingeniero
| País | Solicitud | Comentario |
|---|---|---|
| Netherlands | Semiconductor wafer handler rotation axis | “ISO class 4 accuracy was mandatory for our wafer positioning spec. EVER POWER provided full gear inspection reports. Positioning error was within spec from day one.” ?? Mechanical Lead, Eindhoven. |
| Japan | MRI table drive, medical imaging manufacturer | “Ultra-quiet operation is non-negotiable in a scan room. The two helical stages made the drive essentially inaudible to the patient.” ?? Product Engineer, Nagoya. |
| UK | Precision foil winding machine, speciality film plant | “Pre-loaded bearings solved the axial play problem we had with our previous supplier’s unit. Winding tension consistency improved immediately.” ?? Process Engineer, Birmingham. |
