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

اصل کار
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.
مزایای اصلی
|
● 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. |
فناوری سازه و مواد
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.
سناریوهای کاربردی معمول
| صنعت | کاربرد | 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. |
