EP-ED2250 2-Stage Standard Inline Planetary Gearbox
Brevini Riduttori ED2250 Compatible Replacement | EVER POWER
그만큼 ED2-series delivers a balanced combination of ratio range, efficiency and compactness in a 2-stage inline planetary configuration. With ratio coverage of 10:1 to 50:1 and input speeds to 5,000 rpm, it serves industrial automation, packaging machines, conveyor drives, printing presses and medium-duty machine tool axes where efficiency and moderate reduction are simultaneously required.
그만큼 EP-ED2250 replaces the Brevini riduttori ED2250 ?? a 2-stage inline planetary gearbox delivering approximately 35,200 Nm output torque, ratio range 10:1 – 50:1, and IP rating IP65.

작동 원리
The first stage sun gear accepts motor input. Its planet carrier becomes the second-stage sun shaft, compounding the reduction. A floating sun gear between stages automatically centres the load distribution across all planet contacts, compensating for minor bore concentricity errors and extending planet bearing life in high-cycle automation duty. Both stages share a single oil sump for maintenance-free lubrication across the rated service interval.
핵심 이점
|
▲ 10:1 – 50:1 Ratio Range
Wide 2-stage coverage from one product family. |
▲ Floating Inter-Stage Sun
Self-equalises planet loads ?? extends life in high-cycle duty. |
|
▲ 5,000 rpm Input
High input speed for direct servo or VFD motor coupling. |
▲ Shared Sump Lubrication
Maintenance-free service across both stages. |
|
▲ Direct ED2-Series Replacement
Same mounting interface as Brevini original. |
구조 및 재료 기술
Housing cast from GGG50 연성 주철. Planet gears use 17CrNiMo6 carburised steel, ground to DIN 5. The output shaft is supported by a back-to-back angular contact bearing pair, pre-loaded to eliminate axial play under reversing loads. External seals are NBR compound for mineral and synthetic oil compatibility.

자주 묻는 질문
Q: Can the ED2-series be used with a VFD (variable frequency drive)?
A: Yes. The 5,000 rpm rated input speed accommodates VFD output at standard and boost frequencies. Confirm maximum continuous motor current for thermal sizing.
Q: What is the minimum oil change interval?
A: With synthetic ISO VG 220 oil, first change at 500 hours then every 2,500 hours or 12 months, whichever comes first.
