WPWED Double Speed Cast Iron Worm Reducer — Product Overview

Where the WPWE covers all shaft directions at extreme ratios, the WPWED adds the two features that motorised OEM applications most frequently require: direct IEC motor mounting without adaptor plate, and D-split cover for in-situ worm wheel inspection. The result is a universal motorised extreme-ratio platform — one product covering multiple machine shaft directions, direct motor connection at any orientation, and planned maintenance access without unit removal.

WPWED Double Speed Worm Reducer — Core Features

■ WPW Universal Body + IEC Flange + D-Split + Double Stage

The WPWED builds on the WPWE universal body by adding IEC direct motor mounting (no adaptor) and D-type split housing (in-situ maintenance cover). All WPW shaft direction configurations remain available — extreme ratio, universal orientation, direct motor, in-situ access.

■ D-Split Cover — In-Situ Access at Any WPW Shaft Direction

The D-split housing cover can be removed for worm wheel inspection regardless of which WPW shaft direction configuration is in use — universal maintenance access across all orientations.

■ IEC Motor Flange — No Adaptor in Any Shaft Direction

The IEC 72-1 flange is integrated at the input position regardless of WPW shaft direction — direct motor mount without adaptor plate in all WPWED configurations.

■ Output Torque to 9,066 Nm — Universal Body Full Capacity

WPWED worm gear internals are identical to WPEDA. Universal body does not reduce torque capacity — size 155–250 delivers up to 9,066 Nm.

■ Single Universal Model — Multiple Machine Drive Orientations

WPWED covers all shaft direction requirements of a multi-orientation OEM machine in a single universal model — reducing BOM complexity, spare parts inventory, and maintenance training requirements.

■ Dual Independent Oil Chambers — Direction-Adjusted Volumes

Both stage chambers are independently sealed. Oil volumes are specified per WPW shaft direction in the WPWED lubrication table.

WPWED Worm Reducer — Industry Applications

WPWED double speed worm reducer applications

⚒ Universal OEM Machine Motorised Drive Platform

OEM machine builders use WPWED as the single extreme-ratio motorised drive platform for all shaft direction requirements — IEC motor direct, in-situ maintenance access, and 1/200–1/900+ ratio across every machine drive position.

⚊ Multi-Orientation Processing Line Drives

Packaging and food processing lines with drives in multiple orientations standardise on WPWED for all extreme-ratio motor-direct drive positions — one product, all orientations, planned maintenance access in position.

⚙ Infrastructure & Utility Slow Drives

Dam gates, sluice controls, and utility infrastructure slow drives in multiple shaft direction configurations use WPWED for its combination of direct motor mounting, extreme ratio, and in-situ maintenance capability.

☷ Agricultural Machinery Multi-Axis Drives

Complex agricultural machinery with motor-direct slow drives in multiple axis directions uses WPWED universal body to standardise the complete slow-speed drive system on one product family.

Frequently Asked Questions — WPWED Double Speed Worm Reducer

▶ How does WPWED differ from WPWE?
The WPWE has a standard solid input shaft requiring a coupling and a solid one-piece housing. The WPWED adds an integrated IEC motor flange for direct motor mounting and D-type split housing for in-situ maintenance access. Same ratio range, torque ratings, and universal WPW shaft directions.
▶ Does the IEC flange on WPWED support all WPW shaft direction configurations?
Yes. The IEC flange input is integrated into the WPWED housing at the input shaft position regardless of which WPW shaft direction configuration is selected for the specific installation.
▶ Can the WPWED D-split cover be removed in any installation orientation?
Yes. The D-split design allows the cover to be removed regardless of the WPW shaft direction in use — universal in-situ maintenance access across all mounting orientations.
▶ What is the maximum output torque of WPWED?
WPWED size combination 155–250 delivers up to 9,066 Nm — the same as WPEDA since the worm gear internals are identical.
▶ Are oil volumes in WPWED adjusted per shaft direction?
Yes. The WPW shaft direction affects oil sump geometry in both stage chambers. Use the WPWED lubrication table which specifies the correct oil volume for each chamber at each WPW shaft direction configuration.
