WPDA Single Speed Cast Iron Worm Reducer — WP Series

Aligning a standard AC motor to a gearbox through a separate adaptor plate adds cost, introduces shaft misalignment risk, and wastes axial installation space. The WPDA solves this by integrating an IEC-standard motor flange directly into the gearbox housing. Drop your motor onto the flange, tighten four bolts, and the drive is complete — no coupling, no adaptor, no field alignment.

The D-type split housing adds an independent maintenance advantage: the top cover can be removed without disturbing motor or driven machine connections, enabling in-situ worm wheel inspection that solid-housing units cannot match. With output torques up to 3,025 Nm, the WPDA covers the full range of OEM machine building, pump station, and conveyor drive requirements.

■ Integrated IEC Motor Flange — No Adaptor Required

Machined to IEC 72-1, accepting A02/Y-series motor flanges for frames 56–355 directly. Eliminates the adaptor plate SKU, removes one misalignment source, and reduces installation time by approximately 40% versus coupled configurations.

■ D-Type Split Housing — In-Situ Worm Wheel Access

The two-piece cast iron housing separates at the horizontal centreline. Remove the top cover in-place to inspect or replace the worm wheel without disconnecting the motor or the driven machine.

■ Output Torques from 4 Nm to 3,025 Nm

Size 40 delivers 4–20 Nm for small mechanism drives; size 250 reaches 850–3,025 Nm for heavy conveyor and mixer applications — all within the same WPDA housing design.

■ FC20+ Cast Iron — Superior Vibration Damping

The D-type housing retains the same FC20+ cast iron properties as the solid WPA, providing vibration damping 3× better than aluminium alternatives across the continuous duty cycle.

■ Sealed Air Vent — Prevents Pressure Build-Up

A top-mounted air vent with dust-exclusion filter equalises internal pressure during thermal cycling without allowing contaminant ingress — preventing oil leaks common in unvented housings after sustained operation.

■ Permanent Metal Nameplate — ISO 9001 Traceability

Every WPDA ships with a fixed metal nameplate: model, size, ratio, serial number, and manufacturing date — enabling full supply chain traceability for OEM and maintenance records.

⚒ OEM Machine Building

Machine builders specify the WPDA because the integrated IEC flange eliminates the motor adaptor from the bill of materials, reducing assembly time by up to 40% compared to gearbox-plus-adaptor configurations.

⚙ Pump Station Drives

Direct motor mounting eliminates shaft coupling misalignment — the leading cause of early bearing failure in pump stations. The WPDA keeps motor and reducer rigidly aligned throughout service life.

☷ Textile & Printing Machinery

Printing presses and textile winders require precise, repeatable speed. The WPDA’s integral flange maintains consistent alignment under the vibration inherent in high-speed web handling.

⚊ Automated Production Lines

On assembly lines where rapid motor-reducer swap-out is critical, the WPDA’s four-bolt flange reduces mean time to repair dramatically versus coupled units requiring shaft alignment on the factory floor.

■ ISO 9001:2000 Sertifikalı

Her bir ünite ISO 9001:2000 kalite yönetim standardına uygun olarak üretilmektedir. Hammadde denetimi, süreç içi kontroller ve son testler belgelendirilmekte ve her bir ünitenin seri numarasına kadar takip edilebilmektedir.

■ CE İşareti — AB Makine Direktifi 2006/42/EC

CE uyumluluğunun tam olması, mekanik güç aktarımı için Avrupa güvenlik ve tasarım standartlarına uyumu teyit ederek AB, İngiltere, Avustralya ve Yeni Zelanda pazarlarına ihracatı desteklemektedir.

■ Sevkiyat Öncesi Testler: Gürültü, Sızıntı, Tork

Her bir ünite sevkiyat öncesinde üç testten geçer: nominal yükte 68 dB(A)'nın altında gürültü, 30 dakikalık basınç sızıntısı testi ve nominal değerin ±5% aralığında tork iletimi. Uygun olmayan üniteler yeniden işlenir, sevk edilmez.

■ FC20+ Malzeme Sertifikasyonu

Gövde dökümleri, FC20 sınıfı için fabrika sertifikalarıyla doğrulanır: minimum 220 MPa çekme dayanımı, 160–200 HB sertlik. 135 ve üzeri boyutlarda ultrasonik kusur testi yapılır.

“Standardised on WPDA-100 for all our conveyor upgrade projects. The IEC flange means motor swap in under 30 minutes on-site without alignment tools — critical in dusty, time-sensitive mine maintenance.”

“Packaging machine redesign eliminated adaptor plates and flexible couplings at every drive station by switching to WPDA. Assembly output increased by 15% due to faster build times.”

“WPDA drives our loom main shafts. Direct motor flange eliminated drive vibration we had with belt-driven reducers — fabric defect rate dropped noticeably.”

“Good build quality and easy IEC flange compatibility. D-split housing made our first inspection very fast — worm wheel showed minimal wear at 8,000 hours. Would appreciate more sizes between 135 and 155.”
