EP-PWD2100 Planetary Winch Drive Gearbox<\/h1>\n

Brevini PWD2100 Compatible Replacement | EVER POWER<\/strong><\/p>\n

The EP-PWD2100<\/strong> is EVER POWER’s precision-engineered planetary winch drive gearbox, purpose-built as a direct replacement for the Brevini riduttori PWD2100. Combining robust load capacity with compact design, this unit delivers reliable performance in the most demanding lifting and pulling applications.<\/p>\n

\"EP-PWD2100<\/p>\n

Product Overview<\/h2>\n

Designed for marine winches, crane hoisting systems, offshore lifting platforms<\/strong> and construction material handlers<\/strong>, the EP-PWD2100 integrates a multi-stage planetary gear train inside a sealed housing. Its concentric shaft layout minimises installation footprint while delivering a maximum output torque of 21,000 Nm<\/strong>.<\/p>\n

Core advantages at a glance: high torque density, low backlash, integrated multi-disc wet brake option, and full metric\/imperial mounting compatibility.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

The EP-PWD2100 operates on the epicyclic (planetary) gear principle<\/strong>. The input sun gear meshes simultaneously with multiple planet gears orbiting around it, enclosed within an internally toothed ring gear fixed to the housing. This load-sharing arrangement distributes torque across several contact points simultaneously, achieving far greater torque density than parallel-shaft designs.<\/p>\n

An optional integrated multi-disc wet brake<\/strong> is spring-engaged \/ hydraulically released, providing fail-safe load holding. The output drum flange is directly splined to the planet carrier, giving a rigid, zero-play load path.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n\n\n
● High Torque Density<\/strong>
Achieves 21,000 Nm in a compact envelope, freeing installation space.<\/td>\n		● Precision Low Backlash<\/strong>
Ground planet gears ensure backlash <= 8 arcmin for accurate positioning.<\/td>\n<\/tr>\n
<\/td>\n<\/tr>\n
● Integrated Brake Ready<\/strong>
Bolt-on wet or dry brake interface eliminates external brake brackets.<\/td>\n		● All-Weather Sealing<\/strong>
IP65 standard sealing (IP67 optional) for marine and outdoor duty.<\/td>\n<\/tr>\n
<\/td>\n<\/tr>\n
● Direct Bolt-In Replacement<\/strong>
Mounting dimensions match Brevini PWD2100, requiring no machine modification.<\/td>\n<\/tr>\n<\/table>\n

Structure and Material Technology<\/h2>\n

\"Planetary<\/p>\n

The housing is cast from high-grade ductile iron (GGG50)<\/strong> machined to ISO tolerances. Internal gears are manufactured from 20CrMnTi alloy steel<\/strong>, carburised, quenched and ground to DIN 5 accuracy. Planet pin bearings use double-row tapered roller bearings<\/strong> pre-loaded to minimise radial play. Shaft seals are FKM-grade fluoroelastomer, resistant to synthetic gear oils and hydraulic fluid contamination.<\/p>\n

Selection Guide<\/h2>\n
    \n
  1. Required Output Torque (Nm)<\/strong> – Line pull x drum radius x safety factor.<\/li>\n
  2. Gear Ratio<\/strong> – Motor speed \/ desired drum speed.<\/li>\n
  3. Input Interface<\/strong> – Hydraulic motor (SAE flange type, cc\/rev) or electric motor (IEC frame).<\/li>\n
  4. Brake Requirement<\/strong> – Wet multi-disc, dry disc, or no brake.<\/li>\n
  5. Drum Attachment<\/strong> – Splined drum shaft, flange output or drum-integrated.<\/li>\n
  6. Environment<\/strong> – Sealing class, operating temperature range, corrosion protection level.<\/li>\n<\/ol>\n
