EP-CTD2100 Planetary Track Drive Gearbox ?? 21,000 Nm<\/h1>\n

Brevini CTD2100 Compatible Replacement | EVER POWER<\/p>\n

The EP-CTD2100<\/strong> delivers 21,000 Nm<\/strong> 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<\/strong> that reduces audible noise and gear mesh vibration ?? a feature increasingly specified by European OEMs seeking to meet workplace noise regulations.<\/p>\n

\"EP-CTD2100<\/p>\n

Product Overview<\/h2>\n

Primary applications: 10-14 t hydraulic excavators, tracked trenchers, crawler-mounted concrete pumps and medium-duty tracked dumpers<\/strong>. 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.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

The three-stage arrangement uses a helical-cut first stage<\/strong> 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.<\/p>\n

The multi-disc wet brake<\/strong> 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.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
★ Helical First Stage<\/strong>
Axial contact ratio > 1.2 ?? measurably lower noise and vibration versus straight-cut alternatives.<\/div>\n<\/td>\n
\n
★ Oil-Cooled Brake Stack<\/strong>
Internal oil circulation groove cools disc pack in high-frequency stop-start operations.<\/div>\n<\/td>\n<\/tr>\n
\n
★ IP68 Submersion Seal<\/strong>
Fully sealed for stream crossings, flooded trench work and aggressive pressure washing.<\/div>\n<\/td>\n
\n
★ 3-Stage Torque Density<\/strong>
21,000 Nm in a body sized for the 10-14 t class ?? no upsizing of track frame needed.<\/div>\n<\/td>\n<\/tr>\n
\n
★ Brevini CTD2100 Drop-In Fit<\/strong>
Identical flange dimensions and brake port locations ?? no adaptation components required.<\/div>\n<\/td>\n<\/tr>\n<\/table>\n

Structure and Material Technology<\/h2>\n

Helical first-stage gears are precision-hobbed from 17CrNiMo6 alloy steel<\/strong>, carburised to 0.8-1.1 mm and ground to DIN 5 accuracy. The straight-cut second and third stages use 20CrMnTi steel<\/strong> ground to the same accuracy class. The housing bore is hard-anodised internally<\/strong> in the bearing zones to provide an interference-fit surface that resists fretting corrosion under vibration loading. Output shaft seals are dual-lip FKM fluoroelastomer<\/strong> rated for synthetic gear oil at up to 120 degC.<\/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>\n12 t tracked trencher<\/td>\nHigh-frequency travel reversals; oil-cooled brake critical for brake longevity.<\/td>\n<\/tr>\n
Concrete<\/td>\nCrawler-mounted concrete pump<\/td>\nSlow precise positioning alongside pour; low noise protects operator hearing.<\/td>\n<\/tr>\n
Mining<\/td>\n10 t underground development loader<\/td>\nLow-noise requirement in confined underground tunnels; IP68 handles mine drainage spray.<\/td>\n<\/tr>\n
Demolition<\/td>\n13 t tracked demolition machine<\/td>\nHigh shock loads from concrete breaking; helical first stage absorbs vibration spikes.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Selection Guide<\/h2>\n
    \n
  1. Noise Requirement (dBA)<\/strong> ?? Helical first stage is recommended when machine must meet EN 474 noise limits.<\/li>\n
  2. Brake Cycle Frequency<\/strong> ?? High-frequency stop-start (> 60 cycles\/hour) requires oil-cooled brake spec.<\/li>\n
  3. IP Rating<\/strong> ?? IP68 standard; confirm maximum continuous submersion depth if applicable.<\/li>\n
  4. Motor Displacement<\/strong> ?? Provide cc\/rev and shaft specification for ratio confirmation.<\/li>\n
  5. Operating Temperature<\/strong> ?? Specify if ambient exceeds 40 degC for thermal de-rating check.<\/li>\n<\/ol>\n
