WPWD Worm Reducer — Core Features

■ WPW Universal Body + IEC Flange + D-Split — Three Features

Universal P-housing shaft direction flexibility combined with direct IEC motor mounting (no adaptor) and D-type split housing cover (in-situ worm wheel access). The fully specified universal motorised reducer.

■ IEC Motor Flange — Direct Motor Mount in Any Orientation

IEC 72-1 flange integrated into the P-housing first stage. Motor bolts on in four bolts without adaptor plate in any of the 5 WPW shaft direction configurations.

■ D-Split Housing — In-Situ Maintenance Access

Remove the top cover with motor and driven shaft connected — worm wheel inspection in any WPW shaft direction configuration without unit removal.

■ Output Torque 2.2–4,440 Nm — Full WPW Range

WPWD worm gear internals are identical to WPW. IEC flange and D-split designation do not reduce torque capacity across all 11 standard sizes.

■ Weight 7–481 kg — Universal Motorised Drive Range

From 7 kg (size 40) to 481 kg (size 250), covering all standard OEM machine and industrial process motorised drive requirements.

■ Single Product — All Motorised Drive Orientations

WPWD covers all WPW shaft direction configurations with direct IEC motor — one product model for all motorised drive positions in an OEM machine build.

WPWD Worm Reducer — Industry Applications

WPWD WPW universal worm reducer industry applications

⚒ Universal Motorised OEM Machine Platform

OEM builders use WPWD as the single motorised drive platform across all shaft direction requirements — IEC motor direct, D-split access, universal body eliminates the need for direction-specific motorised reducer SKUs.

⚊ Industrial Process Motorised Drives

Process plant engineers standardise all motorised speed-reduction drives on WPWD for simplified procurement, one spare parts SKU, and consistent maintenance procedures across all drive orientations.

☵ Packaging Machinery Multi-Position Drives

Packaging machine designers use WPWD universal body with IEC motor for all drive positions — horizontal product flow, vertical lift, and side discharge drives all from one product.

⚛ Conveyor System Universal Motor Drives

Conveyor systems with motor-direct drives in multiple orientations standardise on WPWD — universal body, IEC flange, D-split for periodic inspection access at any drive position.

“Used WPWD on our OEM machine builds. Universal body, IEC flange — one product covers all our client’s installation geometry requirements. Eliminated four direction-specific motorised reducer models from our supply chain.”

Melbourne — A.F.
★★★★★

“WPWD as our standard motorised drive across our processing plant. All orientations covered by one part number. Maintenance team trained on one unit only. Significant operational simplification.”

Perth — G.S.
★★★★☆

“Good universal motorised reducer. WPWD-90 on three different orientations. IEC flange and D-split both working as described. Would like a dedicated orientation selection guide with oil level marks for each position.”

Osaka — N.T.

Frequently Asked Questions — WPWD Universal Speed Worm Reducer

▶ How does WPWD differ from WPW?
The WPW uses a standard solid bilateral input shaft requiring a motor coupling and has a solid one-piece housing. The WPWD replaces these with an integrated IEC motor flange for direct motor mounting and D-type split housing for in-situ maintenance. Same shaft direction options, same torque ratings.
▶ What IEC motor frame sizes does WPWD accept?
A02/Y-series: sizes 40–75 accept frames 56–112; sizes 90–130 accept frames 100–160; sizes 150–250 accept frames 132–315. Verify motor LA, LB, LC dimensions against WPWD dimension drawing.
▶ Can the WPWD D-split cover be removed in any WPW shaft direction configuration?
Yes. The D-split cover is accessible regardless of which WPW shaft direction is configured — universal in-situ maintenance access across all installation orientations.
▶ What is the maximum output torque for WPWD?
WPWD size 250 delivers up to 4,440 Nm — the same as WPW since the worm gear internals are identical. IEC flange and D-split features affect mounting only, not torque capacity.
▶ Does the WPWD IEC flange support all WPW shaft directions?
Yes. The IEC flange input is integrated into the P-housing at the input shaft position regardless of which WPW shaft direction configuration is in use.
