EPHD/140 — 18:1

Type: Parallel-shaft helical gearbox (EPHD series)
Ratio: 18 : 1 (speed reduced 18×, torque ~18× × efficiency)
Typical build: Heavy-duty cast-iron housing, hardened & ground helical gears, roller bearings, splash/forced lubrication depending on size & duty.
Mounting / shafts: Foot/base mount; solid or hollow output (keyed), horizontal orientation standard; various input options (motor coupling/adapter or free input shaft).
Use cases: Conveyors, mixers, extruders, hoists — anywhere you want ~80 rpm output from a 4-pole motor.

What 18:1 means for your drive

• Output speed ≈ Input rpm ÷ 18

  • 1440 rpm motor → ~80 rpm

  • 960 rpm motor → ~53 rpm

  • 2880 rpm motor → ~160 rpm

• Torque multiplication ≈ 18 × η (overall efficiency).

  • With η ≈ 0.95 (typical multi-stage helical), torque gain ≈ 17.1×.

Quick torque examples (at 1440 rpm input, η≈0.95)

• 3.7 kW motor → output torque ≈ 420 N·m

• 5.5 kW motor → output torque ≈ 624 N·m

• 7.5 kW motor → output torque ≈ 851 N·m

Formula used:
Motor torque $T_{in}$ ≈ $9550×P\,[\mathrm{kW}] / n\,[\mathrm{rpm}]$.
$T_{out} ≈ T_{in} × 18 × η$.
