EP-PR3065 Planetary Gearbox
EVER POWER 3-Stage Helical Planetary Gearbox ?? High Reduction for Precision Drives
Cái 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.

Nguyên lý hoạt động
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.
Lợi thế cốt lõi
|
● 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. |
Công nghệ cấu trúc và vật liệu
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.
Các kịch bản ứng dụng điển hình
| Ngành công nghiệp | Ứng dụng | Key Requirement |
|---|---|---|
| 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. |

Case Studies ?? Engineer Field Notes
| Quốc gia | Ứng dụng | Feedback |
|---|---|---|
| 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. |
| Nhật Bản | 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. |
