説明
EP-RPR3600 Planetary Gearbox
EVER POWER 3-Stage 98,000 Nm Ultra-Heavy Planetary Gearbox
の EP-RPR3600 is one of EVER POWER’s most powerful RPR series gearboxes, achieving 98,000 Nm output torque with a 3-stage VAR-steel planetary design and ratio range extending to 250:1. Replacing the Brevini riduttori RPR3600, this unit is specified for the most demanding large-scale industrial installations — large cement raw mill and clinker mill main drives, large ship propulsion gearboxes, large slewing ring drive systems, sugar mill main drives and large industrial press drives.

動作原理
Three extra-large-module planetary stages operate with full oil-jet lubrication. The integrated oil cooling heat exchanger — a plate-type oil-to-water cooler built into the housing base — maintains oil temperature below 75 degC even at 98,000 Nm continuous duty in tropical ambient conditions. The output shaft arrangement uses a split-type shrink disc coupling interface for direct connection to large solid shafts without machining the driven shaft.
主な利点
|
▲ 98,000 Nm Ultra-High Torque
One of the highest torque ratings in EVER POWER’s RPR product catalogue. |
▲ Integrated Oil-to-Water Cooler
Plate cooler built into housing base — maintains oil below 75 degC at tropical ambient. |
|
▲ Shrink Disc Coupling Interface
Direct connection to large solid shafts without shaft machining. |
▲ 316 SS Oil Cooler
Compatible with freshwater and sea water cooling circuits. |
|
▲ Direct RPR3600 Replacement
Same external mounting pattern as original Brevini unit. |
構造と材料技術
All gears throughout three stages use 18CrNiMo7-6 VAR steel, ground to DIN ISO 1328 class 5. Planet carriers are massive GGG70 nodular iron forgings — not weldments — for maximum structural integrity. The integrated oil cooler body is 316 stainless steel for compatibility with cooling water from various sources including sea water if required.
典型的なアプリケーションシナリオ
| 業界 | 応用 | Key Requirement |
|---|---|---|
| セメント | Large clinker mill main drive | 98,000 Nm sustained at 6,000+ annual hours — requires VAR + oil-to-water cooler. |
| Sugar | Sugar mill main crushing drive | 250:1 ratio drives crushing rolls at correct surface speed from large motor. |
| 海洋 | Large ship propulsion gearbox assist | Integrated oil cooler critical in engine room ambient temperatures up to 55 degC. |
| Press | Large industrial hydraulic press drive | 98,000 Nm peak torque on press down-stroke handled without overload. |
選択ガイド
- 必要出力トルク（Nm） — Confirm peak and continuous torque requirement with appropriate safety factor.

事例研究 ― エンジニアの現場メモ
| 国 | 応用 | フィードバック |
|---|---|---|
| エジプト | Cement clinker mill main drive, large plant | “Integrated oil cooler eliminated the external oil cooling unit we previously had on the mill platform. Space saving was significant. Oil temperature now stable at 68 degC even in summer.” — Plant Director, Cairo. |
| Cuba | Sugar mill main crushing drive, state refinery | “250:1 ratio allowed us to use our existing motor without replacement. Capital saving was decisive for our budget-constrained modernisation project.” — Technical Director, Havana. |
| 韓国 | Large marine propulsion gearbox assist | “316 SS oil cooler was required for sea water cooling circuit compatibility. EVER POWER confirmed this specification without additional cost.” — Marine Engineer, Ulsan. |
よくある質問
Q: What cooling water flow rate is required for the plate cooler?
A: Standard flow rate is 15-20 litres/minute at inlet temperature below 30 degC. Sea water service requires reduced flow rate — contact our engineering team for a cooling calculation.
Q: Is the shrink disc coupling included?
A: The shrink disc interface boss is standard. The shrink disc itself is sourced separately and matched to the customer’s shaft diameter — EVER POWER can supply or provide the coupling specification.
