Neugart PLFE & WPLFE Flange Output Planetary Gearboxes
The Neugart PLFE & WPLFE Flange Output Planetary Series (featured model: PLFE090 1-Stage 1:5 Ratio) is Neugart's ultra-compact flange output drive platform, engineered specifically for high-torsional-stiffness servo applications requiring direct mechanical coupling via **ISO 9409-1 flange mounting**. By replacing the traditional output shaft with a compact flange face, the PLFE (inline) and WPLFE (right-angle) series drastically shorten overall drive length while enabling direct bolt-on mounting of pinions, belt pulleys, rotary tables, and drive flanges. Built with deep-groove ball bearings and precision spur gearing, PLFE gearheads provide exceptional tipping moment rigidity, low torsional backlash (**<3 to <5 arcmin**), and high dynamic efficiency (up to 97%). Available across 3 modular frame sizes (064, 090, 110) covering 1-stage (3:1 to 10:1) and 2-stage (12:1 to 100:1) reduction ratios with output torques up to **460 Nm**. WE DRIVE HONGKONG LIMITED provides technical sourcing, ratio verification, and custom PCS motor adapter selection for Neugart PLFE & WPLFE flange output planetary gearboxes worldwide.

Shaft Output Reducer to Flange Output Gearbox Upgrade Guide
Direct replacement guide for upgrading inline shaft gearboxes to Neugart PLFE / WPLFE compact flange output units in high-rigidity servo drives:
| Conventional Shaft Output Reducer | Mechanical Limitations | Current Neugart PLFE / WPLFE Equivalent | Key Performance & Flange Advantages |
|---|---|---|---|
| Shaft Reducer with External Shaft Coupling | Long overall length causes mechanical slop and elastic shaft windup | Neugart PLFE064 / PLFE090 Direct Flange Mount | ISO 9409-1 flange interface bolts directly to load, reducing envelope size and windup. |
| Standard Shaft Reducer on Rack & Pinion Axis | Pinion overhung load causes output shaft bending and bearing wear | Neugart PLFE090 / PLFE110 High Tipping Stiffness | Flange output bearing geometry absorbs high radial pinion forces directly without shaft flex. |
| Inline Shaft Drive in Tight Machine Envelope | Tight enclosure prevents inline motor installation | Neugart WPLFE090 Right-Angle Compact 90° Flange | Combines 90° right-angle bevel input with compact flange output for minimal spatial footprint. |
