Neugart WPLN & WPSN Precision Right-Angle Planetary Gearboxes
The Neugart WPLN & WPSN Precision Right-Angle Planetary Series (featured model: WPLN090 1-Stage 1:5 Ratio) is Neugart's flagship precision 90° drive system, engineered specifically for high-end CNC machine tools, robotics, printing machinery, and dynamic servo axes where space is severely restricted. By pairing a high-precision **spiral bevel hypoid input stage with precision ground helical planetary gearing**, the WPLN (round output flange) and WPSN (square output flange) series eliminate axial motor projection while delivering maximum positioning accuracy and whisper-quiet running. Equipped with preloaded tapered roller bearings, these gearheads absorb extreme radial (up to 21,500 N) and axial loads, providing unyielding tipping rigidity under high dynamic start-stop cycles. Offering ultra-low torsional backlash (**<3 to <5 arcmin**) and dynamic efficiency up to 96%, WPLN/WPSN gearboxes are available across 5 modular frame sizes (070, 090, 115, 142, 190) covering ratios from 3:1 to 100:1 with output torques up to **1,800 Nm**. WE DRIVE HONGKONG LIMITED provides technical sourcing, ratio verification, and custom PCS motor adapter selection for Neugart WPLN & WPSN precision right-angle planetary gearboxes worldwide.

Standard Right-Angle Reducer to Neugart WPLN/WPSN Precision Upgrade Guide
Direct replacement guide for upgrading standard high-backlash right-angle gearboxes to high-precision helical Neugart WPLN and WPSN units:
| Conventional Right-Angle Gearbox | Limitations & Mechanical Failures | Current Neugart WPLN / WPSN Equivalent | Key Upgrades & Precision Advantages |
|---|---|---|---|
| Standard Worm Reducer on Servo Axis | High backlash (>20') and low efficiency (<70%) cause heat build-up and hunting | Neugart WPLN070 / WPLN090 Low Backlash Hypoid Stage | Spiral bevel hypoid stage delivers <3 arcmin backlash and up to 96% dynamic efficiency. |
| Inline Servo Reducer in Tight Enclosure | Axial motor overhang prevents machine enclosure doors from closing properly | Neugart WPLN090 / WPSN090 Compact 90° Integration | 90° right-angle orientation saves critical machine length while retaining helical precision. |
| Standard Bevel Reducer on Heavy Pinion Axis | Shaft flex and bearing failure under dynamic overhung radial load | Neugart WPLN115 / WPSN142 Tapered Roller Bearings | Preloaded tapered roller bearings absorb massive radial and axial shaft loads directly. |
