WPWDKA Universal-Schneckengetriebe | Industriegetriebe

Carburized Worm, 56–62 HRC

20CrMnTi steel worm undergoes carburizing and oil quenching, reaching a surface hardness of 56–62 HRC. The result: a heavy duty worm drive gearbox capable of handling shock loads without accelerated wear — validated across high-cycle packaging and ceramics lines.

Modular Mounting — Universal Fit

This universal worm gearbox accepts IEC B5 and B14 flanges from 56 to 80 frame. Input shaft or hollow-bore options allow direct motor-mounting, eliminating coupling misalignment error in the majority of installations.

HT200 Iron Housing — Passive Thermal Control

Grey cast iron at this wall thickness dissipates heat 35–40% more effectively than fabricated steel housings of equivalent size, allowing continuous-duty operation in ambient temperatures up to 40°C without an external fan or oil cooler on sizes ≤135.

Double-Stage Cascading for Extended Ratios

Two WPWDKA units bolt together to reach compound ratios far beyond 1:60 — an approach sourced from worm gear reducer manufacturers who serve textile and chemical dosing lines where extreme speed reduction at controlled output torque is mandatory.

Low Acoustic Signature

The bronze gear–hardened worm mesh geometry maintains mesh contact across ≥2 teeth simultaneously, damping vibration at the source. Operating noise on size-80 units measures <65 dB(A) at 1 m under no-load conditions — suitable for food-grade and packaging environments.

Synthetic or Mineral Lubrication

Factory oil-filled and tested before shipping. Compatible with ISO VG 220/320 mineral oils and PAO-based synthetics — extend oil change intervals to 8,000 hours in low-contamination environments when synthetic is used.

Q1: What’s the maximum continuous input speed for the WPWDKA worm gear speed reducer?

Rated input speed is 1,450 RPM (50 Hz, 4-pole motor) for all standard sizes. At ratios of 1:60 this produces output speeds as low as ~24 RPM. If your process runs a 60 Hz supply (1,750 RPM input), derate the output torque by approximately 10% and verify the thermal rating with our engineering team before committing.

Q2: Can I use this as a heavy duty worm drive gearbox in outdoor or washdown environments?

The standard KSK oil seal gives IP54-equivalent ingress protection in most orientations. For full outdoor or washdown use, specify the optional stainless shaft extension and enhanced seal package. The HT200 housing is finished with an enamel primer coat; a topcoat is recommended for salt-air or chemical-exposure environments.

Q3: How do I select the right size from the WP series universal worm gear speed reducer range?

Start with required output torque and ratio, then cross-reference the dimensional table above. The size code (40–250) equals the center distance in mm between worm and gear axes. When the required torque falls between two sizes, always select the larger — continuous operation at 80–90% rated torque extends gear life significantly vs. running at the nameplate limit.

Q4: Is the WPWDKA compatible with VFD (variable frequency drive) control?

Yes. The housing and gear set tolerate VFD-induced harmonics without special modification. At frequencies below 20 Hz, however, forced lubrication of the worm contact zone reduces — so restrict minimum speed to 30% of rated RPM in continuous VFD operation, or consult us about adding a forced-cooling option on size 155 and above.

Q5: What is the first oil change interval for a new worm gear reducer?

Drain and refill after the first 200–300 operating hours to remove break-in metal particles. After that: mineral oil every 3,000 hours; PAO synthetic every 8,000 hours. Use ISO VG 220 for ambient temps 10–40°C; switch to VG 320 if ambient exceeds 40°C. Never mix oil types within a service interval.

“We swapped out a competing brand on our packaging line — the WPWDKA 100 ran quieter from day one. After 14 months of three-shift operation, zero oil leaks and no bearing replacement needed. The specs on the data sheet actually matched what arrived.”

“I ordered a size 80 to slow down my wood-veneer conveyor. Arrived pre-filled with oil, bolted straight to a 0.75 kW motor, and the ratio was spot on. Honestly didn’t expect a gearbox to be exciting, but here we are — I told my whole workshop about it. High drama in the reducer department.”

“Sourced 12 units of WPWDKA 135 for a ceramic tile plant retrofit. Lead time was 8 days for that quantity — faster than previous suppliers. One unit shipped with a minor paint nick, which was resolved immediately. Overall the dimensional accuracy was consistent across all 12 pieces.”

Splined Shafts & Yokes

Connect motor to gearbox input without misalignment stress. Machined to ±0.02 mm on spline pitch.

IEC Adapter Flanges

B5 and B14 adapters for frames 56 through 132 — bolt directly to the WPWDKA input face.

Zahnkupplungen

Rigid and flexible jaw couplings to link the output shaft to conveyors, agitators, or secondary gearboxes.

Landwirtschaftliche Getriebe

Mower & disc-bine gearboxes, spreader drives, and PTO shafts for equipment running alongside worm reducers.

Torque Limiters & Overload Clutches

Protect the gearbox from shock-load damage in wood chipper and crusher applications.
