EP-CTD1020 Compact Planetary Travel Drive Gearbox
Brevini CTD1020 Compatible Replacement | EVER POWER
Cái EP-CTD1020 is EVER POWER’s entry-level planetary travel drive gearbox, engineered as a precise drop-in replacement for the Brevini riduttori CTD1020. Delivering 10,200 Nm output torque from a lightweight, flange-mounted body, this unit keeps compact tracked carriers, micro-excavators and light industrial crawler systems running efficiently and economically.
Tổng quan sản phẩm
The EP-CTD1020 serves compact construction, agricultural, robotic and light industrial crawler markets. Its 2-stage epicyclic design keeps the housing short and the weight low ?? ideal for OEMs designing tight-envelope track frames where every kilogram and millimetre counts.
Core highlights: 10,200 Nm rated output torque, 2-stage planetary reduction, integrated spring-applied failsafe brake, SAE-B motor flange, IP67 sealing, -20 degC to +80 degC operating range.

Nguyên lý hoạt động
Input from the hydraulic travel motor spins the first-stage sun gear. Multiple planet gears orbit the sun and react against a fixed ring gear, multiplying torque at the first-stage planet carrier. That carrier feeds the second stage for a final cumulative reduction of up to 50:1. The integrated spring-applied, hydraulically released disc brake engages automatically on loss of hydraulic pressure, preventing roll-back on slopes.
Lợi thế cốt lõi
|
● Lightweight Compact Design
Aluminium option brings housing weight below 22 kg ?? ideal for battery-powered compact carriers. |
● IP67 All-Round Sealing
Withstands temporary immersion, high-pressure wash and muddy terrain without seal failure. |
|
● Failsafe Spring Brake
Spring-engaged brake holds position on slopes whenever hydraulic pressure is removed. |
● Wide Ratio Selection
16:1 to 50:1 range covers both slow-work and faster-travel speed requirements in one platform. |
|
● Direct CTD1020 Drop-In Fit
Matching flange pattern and spline spec ?? bolt-in replacement without machine modification. |
Công nghệ cấu trúc và vật liệu
The housing is available in die-cast aluminium alloy (lightweight duty) or GGG40 ductile iron (heavy duty). Planet gears are cut from Thép tôi cứng bề mặt 20CrMnTi, carburised to 0.6-0.9 mm and ground to DIN 6 accuracy. The output flange bearing is a four-point contact slewing ring rated for combined axial, radial and overturning loads from the track chain. All seals use NBR compound, standard for mineral and synthetic gear oils.
Các kịch bản ứng dụng điển hình
| Ngành công nghiệp | Machine / Use | Key Requirement |
|---|---|---|
| Construction | Compact (1-3 t) mini-excavator | Low weight critical for transported machine; 2-stage gives correct digging torque. |
| Agriculture | Narrow-track vineyard tractor chassis | Short housing fits between track frame rails; IP67 handles mud and spray. |
| Robotics | Outdoor inspection crawler | Battery-powered; aluminium housing minimises current draw per metre travelled. |
| Industrial | Light AGV / factory floor crawler | Smooth slow-speed positioning; spring brake holds position on ramps. |
Hướng dẫn lựa chọn
- Machine Weight (kg) – Determines required drawbar pull and minimum output torque.
- Travel Speed (m/min) – Fixes the ratio given the motor displacement and sprocket diameter.
- Giao diện động cơ – SAE-B 2-bolt or 4-bolt; confirm shaft diameter and keyway.
- Vật liệu xây nhà – Specify aluminium (weight priority) or ductile iron (heavy-duty).
- Battery or Engine Powered – Low-temperature start requirement affects oil and seal grade choice.

Case Studies ?? Engineer Field Notes
| Quốc gia | Ứng dụng | Phản hồi của khách hàng |
|---|---|---|
| Nhật Bản | Compact vineyard crawler, 1.8 t, aluminium housing | “The weight saving over the cast iron version was 6 kg per side ?? exactly what we needed to stay under the transport weight limit.” ?? Design Engineer, Nagano OEM. |
| Netherlands | Battery-powered inspection crawler for dike monitoring | “IP67 sealing survived a full immersion incident during a flood test. Gearbox was completely unaffected.” ?? R&D Manager, Delft. |
| Mexico | Mini-excavator rental fleet overhaul, 12 units | “Drop-in replacement with zero modification. All 12 installed in two days. Cost saving funded two additional units.” ?? Workshop Manager, Guadalajara. |
Câu hỏi thường gặp
Q: What is the maximum static brake holding torque?
A: The spring brake provides a minimum static holding torque of 1.4x the rated output torque, sufficient for 25 deg slope hold.
Q: Can the aluminium housing be used in abrasive environments?
A: We recommend the ductile iron housing for abrasive soil or rock environments. Aluminium is best suited for clean-environment robotic and agricultural applications.
Q: Do you stock spare seal kits?
A: Yes. Standard seal kits for every EP-CTD model are stocked for same-week dispatch.
