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
⚒ 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.
