Deskripsi
EP-RPR2255 Planetary Gearbox
EVER POWER 2-Stage Industrial Planetary Gearbox with Integrated Cooling Flange
Itu EP-RPR2255 is a closely related variant to the RPR2250 series, incorporating an integrated cooling fin array on the output flange that increases passive heat dissipation by 18% versus a plain flange ?? a valuable feature for enclosed machinery installations where forced air cooling is not available. Replacing Brevini riduttori RPR2255, this unit delivers 26,500 Nm output torque for enclosed pump drives, marine gearrooms, underground machinery and thermally constrained industrial equipment.

Prinsip Kerja
The 2-stage planetary layout is identical to the RPR2250 in gear geometry. The differentiating feature is the cooling fin flange ?? cast integrally into the output end bell, its extended surface area conducts frictional heat from the oil sump to ambient air by natural convection. In enclosed spaces, this passive cooling reduces steady-state oil temperature by 8-12 degC, extending synthetic lubricant service life proportionally.
Keunggulan Utama
|
◼ Integrated Cooling Fin Flange
18% more passive heat dissipation ?? reduces oil temperature 8-12 degC without external cooling. |
◼ Aluminium Fin + Iron Housing
Best of both materials ?? aluminium thermal conductivity, iron structural strength. |
|
◼ FKM High-Temp Seals
Synthetic oil service at up to 130 degC ?? suitable for hot enclosed installations. |
◼ 2-Stage High Efficiency
Minimises heat generation at source in thermally constrained installations. |
|
◼ Direct RPR2255 Replacement
Same mounting interface as original Brevini unit. |
Teknologi Struktur dan Material
Housing material is Besi cor ulet GGG50; the cooling fin flange is a separate EN-AC 46000 aluminium alloy casting bolted to the output end, combining aluminium’s superior thermal conductivity with the structural strength of the iron housing. Planet gears use 17CrNiMo6 carburised and ground steel. Seals are fluoroelastomer FKM for high-temperature synthetic oil service.
Skenario Aplikasi Khas
| Industri | Aplikasi | Persyaratan Utama |
|---|---|---|
| Laut | Engine room pump drive, no external cooling | Fin flange provides essential passive cooling in enclosed engine room. |
| Underground | Mine dewatering pump drive | Passive cooling avoids need for forced-air ducting in confined drives. |
| Oil & Gas | Enclosed wellhead pump gearbox | 8-12 degC oil temperature reduction extends lubricant service interval. |
| Industrial | Printing press main drive in enclosed cabinet | Passive cooling maintains oil temperature within limits without cabinet fans. |

Studi Kasus ?? Catatan Lapangan Teknik
| Negara | Aplikasi | Masukan |
|---|---|---|
| Singapore | Marine engine room pump drive, container vessel | “Engine room temperatures reach 48 degC. The fin flange dropped oil temperature by 11 degC, extending our oil change interval from 1,000 to 2,000 hours.” ?? Chief Engineer, Port of Singapore. |
| Afrika Selatan | Underground dewatering pump, gold mine | “No space for forced-air ducting. Passive cooling was the only viable option. EVER POWER’s fin flange solved the problem that had caused two competitors’ units to fail due to overheating.” ?? Mine Engineer, Johannesburg. |
| Inggris | Printing press main drive, enclosed cabinet | “Cabinet temperature regulation was always a problem. Fin flange solved it permanently ?? cabinet fan now runs at minimum speed only.” ?? Production Manager, Leeds. |
Pertanyaan yang Sering Diajukan
Q: Can the cooling fin flange be retrofitted to an existing EP-RPR2250?
A: No. The fin flange end bell is a different casting. It must be specified at order. The two housings are externally identical in mounting dimensions.
Q: What is the maximum ambient temperature for the cooling fin design?
A: The fin flange design maintains oil temperature below 90 degC at up to 50 degC ambient at rated load. Above 50 degC ambient, an oil-to-water cooler option is available.
