EP-CTD1020 Compact Planetary Travel Drive Gearbox<\/h1>\n

Brevini CTD1020 Compatible Replacement | EVER POWER<\/p>\n

The EP-CTD1020<\/strong> 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<\/strong> 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.<\/p>\n

\"EP-CTD1020<\/p>\n

Product Overview<\/h2>\n

The EP-CTD1020 serves compact construction, agricultural, robotic and light industrial crawler markets<\/strong>. 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.<\/p>\n

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.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

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<\/strong> engages automatically on loss of hydraulic pressure, preventing roll-back on slopes.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
● Lightweight Compact Design<\/strong>
Aluminium option brings housing weight below 22 kg ?? ideal for battery-powered compact carriers.<\/div>\n<\/td>\n
\n
● IP67 All-Round Sealing<\/strong>
Withstands temporary immersion, high-pressure wash and muddy terrain without seal failure.<\/div>\n<\/td>\n<\/tr>\n
\n
● Failsafe Spring Brake<\/strong>
Spring-engaged brake holds position on slopes whenever hydraulic pressure is removed.<\/div>\n<\/td>\n
\n
● Wide Ratio Selection<\/strong>
16:1 to 50:1 range covers both slow-work and faster-travel speed requirements in one platform.<\/div>\n<\/td>\n<\/tr>\n
\n
● Direct CTD1020 Drop-In Fit<\/strong>
Matching flange pattern and spline spec ?? bolt-in replacement without machine modification.<\/div>\n<\/td>\n<\/tr>\n<\/table>\n

Structure and Material Technology<\/h2>\n

The housing is available in die-cast aluminium alloy<\/strong> (lightweight duty) or GGG40 ductile iron<\/strong> (heavy duty). Planet gears are cut from 20CrMnTi case-hardening steel<\/strong>, carburised to 0.6-0.9 mm and ground to DIN 6 accuracy. The output flange bearing is a four-point contact slewing ring<\/strong> rated for combined axial, radial and overturning loads from the track chain. All seals use NBR compound<\/strong>, standard for mineral and synthetic gear oils.<\/p>\n

Typical Application Scenarios<\/h2>\n\n\n\n\n\n\n\n
Industry<\/th>\nMachine \/ Use<\/th>\nKey Requirement<\/th>\n<\/thead>\n
Construction<\/td>\nCompact (1-3 t) mini-excavator<\/td>\nLow weight critical for transported machine; 2-stage gives correct digging torque.<\/td>\n<\/tr>\n
Agriculture<\/td>\nNarrow-track vineyard tractor chassis<\/td>\nShort housing fits between track frame rails; IP67 handles mud and spray.<\/td>\n<\/tr>\n
Robotics<\/td>\nOutdoor inspection crawler<\/td>\nBattery-powered; aluminium housing minimises current draw per metre travelled.<\/td>\n<\/tr>\n
Industrial<\/td>\nLight AGV \/ factory floor crawler<\/td>\nSmooth slow-speed positioning; spring brake holds position on ramps.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Selection Guide<\/h2>\n
    \n
  1. Machine Weight (kg)<\/strong> – Determines required drawbar pull and minimum output torque.<\/li>\n
  2. Travel Speed (m\/min)<\/strong> – Fixes the ratio given the motor displacement and sprocket diameter.<\/li>\n
  3. Motor Interface<\/strong> – SAE-B 2-bolt or 4-bolt; confirm shaft diameter and keyway.<\/li>\n
  4. Housing Material<\/strong> – Specify aluminium (weight priority) or ductile iron (heavy-duty).<\/li>\n
  5. Battery or Engine Powered<\/strong> – Low-temperature start requirement affects oil and seal grade choice.<\/li>\n<\/ol>\n
