EP-CTU3200 Planetary Track Drive Gearbox
Brevini CTU3200 Compatible Replacement | EVER POWER
The EP-CTU3200 by EVER POWER delivers ۳۲۰۰۰ نیوتن متر output torque in a compact 2-to-3-stage sealed planetary housing, engineered as a cost-effective, form-fit replacement for the Brevini riduttori CTU3200. Designed for mid-to-large tracked construction and earthmoving equipment, this unit combines wide ratio coverage with all-terrain sealing to minimise unplanned downtime.

بررسی اجمالی محصول
Primary markets: 18-25 t hydraulic excavators, crawler-mounted pipe layers, tracked soil stabilisers and large tunnelling machines. The EP-CTU3200 features an extended ratio range of 25:1 to 120:1 achieved through a configurable 2-or-3-stage arrangement, allowing a single part number to serve machines with significantly different travel speed requirements without any housing change.

اصل کار
In 3-stage configuration, the first two stages use a standard 3-planet arrangement for high input speed tolerance; the final stage upgrades to a 4-planet carrier for enhanced torque capacity at the output. This hybrid arrangement allows the EP-CTU3200 to handle both the high-speed continuous travel phase and the high-torque low-speed pushing phase of excavator track operation without thermal de-rating.
The floating sun gear shaft design automatically centres the load distribution across all planet gears, compensating for minor shaft misalignment caused by track chain tension deflection and chassis flexion during operation.
مزایای اصلی

| ▲ 2-or-3-Stage Flexibility One part number covers 25:1-120:1 ratio range – simplifies procurement and spares stocking. |
▲ Floating Sun Gear Self-equalises planet load distribution, extending tooth life under chassis deflection loads. |
| ▲ 4-Planet Output Stage Higher tooth contact count reduces root stress, supporting rated torque at extreme duty cycle. |
▲ -30 degC Cold Start Arctic-grade synthetic oil and cold-rated FKM seals ensure clean cold-morning engagement. |
| ▲ Direct Brevini CTU3200 Replacement Same flange pattern, spline spec and brake port locations – swap in place with no machine modification. |

فناوری سازه و مواد
All gear blanks are precision-forged from فولاد سخت شونده سطحی 17CrNiMo6, vacuum degassed for superior core impact toughness. Post-carburising case depth is controlled to 0.9-1.2 mm; tooth flanks are profile-ground to ISO/DIN accuracy class 5. The output flange is machined with a T-slot register face for accurate sprocket centering without adjustment shims. O-ring face seals use ترکیب HNBR for resistance to biodegradable hydraulic fluids increasingly specified on European and Japanese job sites.
سناریوهای کاربردی معمول
| صنعت | Machine Type | الزامات کلیدی |
|---|---|---|
| ساخت و ساز | 20 t excavator | High-cycle travel; 3-stage for fast tramming speed on road. |
| تونل سازی | Crawler-mounted shotcrete robot | Slow precise positioning in confined tunnel bores; high torque for gradients. |
| خط لوله | Tracked pipelayer (side-boom crane) | Smooth slow-speed travel alongside open trench with heavy suspended pipe. |
| Agriculture | Large tracked harvester chassis | Wide ratio range handles both field travel speed and headland turning torque. |
راهنمای انتخاب
- Drawbar Pull (kN) – Required traction force on worst-case gradient x safety factor (1.3 minimum).
- تعداد مرحله – Choose 2-stage for max travel speed; 3-stage for maximum torque at given motor size.
- Motor Shaft Interface – Splined (DIN 5480) or keyed shaft; confirm bore diameter.
- Brake Release Pressure – 20-40 bar available hydraulic pressure to release spring brake.
- Biodegradable Oil Requirement – Specify HNBR seals if bio-hydraulic fluid is used on site.

| کشور | کاربرد | بازخورد |
|---|---|---|
| نروژ | 20 t excavator fleet for fjord-side infrastructure project | “Cold-start at -28 degC with no sluggishness. The floating sun design clearly handles the rocky terrain chassis flex we experience.” – Site Manager, Bergen contractor. |
| کره جنوبی | Tunnelling crawler robot for subway expansion | “Slow-speed precision was critical for our robotic lining installation. EP-CTU3200 delivered consistent low-speed control throughout the 14-month project.” – Mechanical Lead, Seoul. |
| Argentina | Large tracked soybean harvester chassis replacement | “Six units replaced in one off-season. Cost saving allowed us to order two spare sets for inventory. Delivery was faster than any European supplier could offer.” – Procurement Manager, Rosario. |
سوالات متداول
Q: Can I switch between 2-stage and 3-stage in the field?
A: Stage count is set at factory. Specify your required ratio range at order and we will configure correctly. Mixed-stage sets are available for fleets needing different travel speeds.
Q: Are HNBR seals an additional cost option?
A: HNBR seals are available at minimal additional cost. Please specify “bio-hydraulic oil service” at order.
