EP-CTD2100 Planetary Track Drive Gearbox ?? 21,000 Nm
Brevini CTD2100 Compatible Replacement | EVER POWER
Cái EP-CTD2100 delivers 21,000 Nm output torque in a sealed, spring-brake-integrated planetary housing, engineered to replace the Brevini riduttori CTD2100 without any machine modification. Designed for 10-14 t tracked construction equipment, this unit introduces a helical first stage that reduces audible noise and gear mesh vibration ?? a feature increasingly specified by European OEMs seeking to meet workplace noise regulations.
Tổng quan sản phẩm
Primary applications: 10-14 t hydraulic excavators, tracked trenchers, crawler-mounted concrete pumps and medium-duty tracked dumpers. The helical first stage is the EP-CTD2100’s defining feature ?? it generates an axial contact ratio above 1.2, smoothing the torque handover between successive tooth engagements and producing measurably lower radiated noise compared to the straight-cut first stage used in most track drives at this torque level.

Nguyên lý hoạt động
The three-stage arrangement uses a helical-cut first stage to absorb high-speed input from the travel motor with reduced noise and vibration. The torque amplified by stage 1 feeds into stages 2 and 3 (straight-cut, optimised for torque density), achieving the rated output ratio at the sprocket shaft.
Cái multi-disc wet brake between the motor interface and stage 1 is hydraulically released during travel and spring-applied at all other times. The disc stack is oil-cooled via a dedicated internal oil circulation groove, extending brake life in high-frequency stop-start duty.
Lợi thế cốt lõi
|
★ Helical First Stage
Axial contact ratio > 1.2 ?? measurably lower noise and vibration versus straight-cut alternatives. |
★ Oil-Cooled Brake Stack
Internal oil circulation groove cools disc pack in high-frequency stop-start operations. |
|
★ IP68 Submersion Seal
Fully sealed for stream crossings, flooded trench work and aggressive pressure washing. |
★ 3-Stage Torque Density
21,000 Nm in a body sized for the 10-14 t class ?? no upsizing of track frame needed. |
|
★ Brevini CTD2100 Drop-In Fit
Identical flange dimensions and brake port locations ?? no adaptation components required. |
Công nghệ cấu trúc và vật liệu
Helical first-stage gears are precision-hobbed from 17CrNiMo6 alloy steel, carburised to 0.8-1.1 mm and ground to DIN 5 accuracy. The straight-cut second and third stages use 20CrMnTi steel ground to the same accuracy class. The housing bore is hard-anodised internally in the bearing zones to provide an interference-fit surface that resists fretting corrosion under vibration loading. Output shaft seals are dual-lip Chất đàn hồi flo FKM rated for synthetic gear oil at up to 120 degC.
Các kịch bản ứng dụng điển hình
| Ngành công nghiệp | Machine / Use | Yêu cầu chính |
|---|---|---|
| Construction | 12 t tracked trencher | High-frequency travel reversals; oil-cooled brake critical for brake longevity. |
| Concrete | Crawler-mounted concrete pump | Slow precise positioning alongside pour; low noise protects operator hearing. |
| Khai thác mỏ | 10 t underground development loader | Low-noise requirement in confined underground tunnels; IP68 handles mine drainage spray. |
| Demolition | 13 t tracked demolition machine | High shock loads from concrete breaking; helical first stage absorbs vibration spikes. |
Hướng dẫn lựa chọn
- Noise Requirement (dBA) ?? Helical first stage is recommended when machine must meet EN 474 noise limits.
- Brake Cycle Frequency ?? High-frequency stop-start (> 60 cycles/hour) requires oil-cooled brake spec.
- Xếp hạng IP ?? IP68 standard; confirm maximum continuous submersion depth if applicable.
- Motor Displacement ?? Provide cc/rev and shaft specification for ratio confirmation.
- Nhiệt độ hoạt động ?? Specify if ambient exceeds 40 degC for thermal de-rating check.

| Đức | 12 t tracked trencher, utility contractor | “The noise reduction was immediate and measurable. Our operator health monitoring dropped by 4 dB on the first day after retrofit. That alone justified the purchase.” ?? Safety Manager, Cologne. |
| Úc | Underground development loader, gold mine | “IP68 sealing held up perfectly in the wet drives where water is constant. Oil-cooled brake has shown zero wear increase after 3,000 cycles.” ?? Mine Maintenance Engineer, Kalgoorlie. |
| Pháp | 13 t demolition robot, urban project | “Urban demolition requires low noise for permits. EP-CTD2100 helped us secure a noise variance for a sensitive site near a school.” ?? Project Manager, Paris. |
Câu hỏi thường gặp
Q: Does the helical first stage require special lubrication?
A: No. Synthetic ISO VG 220, the same spec used throughout the unit, is fully compatible with helical gears and is factory-filled.
Q: What is the maximum continuous submersion depth for IP68?
A: IP68 is tested to 1 metre for 30 minutes continuous submersion per IEC 60529. Deeper or longer submersion requires the optional deep-submersion seal upgrade.
Q: Can the oil-cooled brake be retro-fitted to an existing non-cooled unit?
A: No ?? the oil circulation groove is machined into the housing casting. It cannot be retrofitted. Specify oil-cooled brake at order.
