EP-RPR2250 Planetary Gearbox
EVER POWER Heavy-Duty 2-Stage Planetary Gearbox for High-Efficiency Industrial Drives
De EP-RPR2250 levert 25,500 Nm in a 2-stage layout, engineered to replace the Brevini riduttori RPR2250. Its 2-stage design provides the best efficiency figure in the RPR250 size class ?? important for energy-intensive applications such as cement mill drives, large fan drives, pump drives and heavy machine tool main spindles where electrical energy cost over the product life significantly exceeds the purchase price.

Werkingsprincipe

Two large-module planetary stages handle the high input torque from primary motors rated up to several hundred kilowatts. The forged planet carrier in each stage is a single-piece construction ?? avoiding welded split-type carriers that can flex under peak loads and cause uneven planet load distribution. A baas van thermische monitoring on the housing allows a PT100 probe to be fitted for oil temperature surveillance in energy-intensive continuous duty installations.
Kernvoordelen
|
● High Efficiency 2-Stage
Minimum energy loss ?? critical for high-power continuous-duty installations. |
● Forged One-Piece Carrier
No weld-line flex ?? even planet loading under peak torque. |
|
● Thermal Monitoring Boss
PT100 probe port for DCS integration and oil temperature trending. |
● GGG70 High-Grade Housing
Maximum stiffness for large-module gear loading in heavy-duty installations. |
|
● Marine C4 Epoxy Coating
Outdoor and industrial environment corrosion protection. |
Structuur- en materiaaltechnologie

Alle tandwielen zijn gesmeed uit 18CrNiMo7-6 alloy steel, vacuum-degassed, carburised to 1.0-1.3 mm and ground to DIN 5. The ring gear is press-fitted into a GGG70 nodular iron housing ?? the highest iron grade in EVER POWER’s housing series ?? providing maximum stiffness for large module gear loading. External coating is marine epoxy C4 standard for outdoor and factory floor environments.
Typische toepassingsscenario's
| Industrie | Sollicitatie | Kernvereiste |
|---|---|---|
| Cement | Cement raw mill drive | High continuous power; thermal monitoring boss allows integration with mill DCS. |
| HVAC | Large centrifugal fan main drive | 2-stage high efficiency reduces fan house energy consumption. |
| Water | Large vertical pump drive | Any-axis mounting allows direct coupling to vertical pump shaft without bevel gear. |
| Gereedschapswerktuig | Heavy milling machine main spindle | 25,500 Nm handles face milling of large workpieces without stall risk. |
Selectiegids
- Vereist uitgangskoppel (Nm) Bevestig de piek- en continue koppelvereisten met de juiste veiligheidsfactor.
- Overbrengingsverhouding ?? Motortoerental (rpm) gedeeld door het gewenste uitgangstoerental (rpm).
- Bedrijfscyclus ?? Continue S1 of intermitterende S3/S6; beïnvloedt de thermische vermindering.
- Motorinterface Flenstype (SAE/ISO), asdiameter, spiebaan- of vertandingsspecificatie.
- Omgeving IP-klasse, omgevingstemperatuur, corrosiezone, oriëntatie.

Casestudies ?? Veldnotities van ingenieurs
| Land | Sollicitatie | Feedback |
|---|---|---|
| Turkey | Cement raw mill drive, large plant upgrade | “PT100 monitoring integration into our DCS allowed us to detect a bearing developing over 6 weeks. Planned replacement prevented an unplanned 48-hour shutdown.” ?? Maintenance Director, Ankara. |
| Denmark | Large offshore wind farm cooling fan drive | “2-stage efficiency was decisive ?? every percentage point of drive efficiency matters at our scale. EVER POWER’s data confirmed 97.8% transmission efficiency on our test rig.” ?? Engineer, Copenhagen. |
| Vietnam | Heavy vertical pump drive, irrigation scheme | “Vertical mounting with the motor on top was accommodated without any modification. EVER POWER confirmed orientation compatibility within 24 hours.” ?? Project Manager, Ho Chi Minh City. |
Veelgestelde vragen
Q: What is the thermal limit of the EP-RPR2250?
A: Continuous thermal rating is 75 kW at 40 degC ambient. De-rating applies at higher ambient temperatures ?? contact us for a thermal calculation for your specific application.
Q: Is the PT100 monitoring boss factory-fitted?
A: Yes, the boss is machined into every EP-RPR2250 housing as standard. It is plugged with a G1/4 hex plug unless a probe is specified at order.
