WPDKA Cast Iron Worm Reducer — Product Overview
Most drive trains require three separate components between motor and driven shaft: a motor adaptor, a gearbox, and an output coupling. The WPDKA consolidates all three functions into a single cast iron worm reducer. The integrated IEC motor flange mounts the motor directly — no adaptor. The K-type hollow bore output receives the driven shaft directly — no coupling. The D-type split housing enables in-situ worm wheel maintenance — no teardown.
The result is the lowest component count, shortest installed drive length, and fastest maintenance access available in the WP worm reducer series. One WPDKA unit replaces gearbox plus adaptor plus coupling across the full size range of 40–250 mm centre distance.

WPDKA Worm Reducer — Core Features
■ D-Type Split Housing — In-Situ Maintenance
Remove the top cover with motor and driven shaft in place. Inspect and replace the worm wheel without disconnecting any drive train element — the fastest maintenance access in the WP series.
■ IEC Motor Flange — Zero Adaptor Plate
Factory-machined IEC 72-1 flange accepts A02/Y-series motors frames 56–355 directly. Eliminates one component and one potential misalignment source from the drive train.
■ K-Type Hollow Bore — No Output Coupling
Precision H7-tolerance bore with GB/T 1095 keyway. Insert the driven shaft directly and key. No coupling lubrication, no coupling fatigue failure, and no coupling mass on the shaft overhang.
■ One Unit Replaces Three Components
WPDKA replaces the motor adaptor plate + gearbox + output coupling, reducing BOM count by two components, installation time by approximately 50%, and total installed drive length by 60–200 mm depending on size.
■ FC20+ Cast Iron Housing — Full Rigidity
Triple-feature architecture does not compromise structural integrity. The WPDKA retains FC20+ cast iron with 95°C continuous oil temperature rating, identical to the standard WPA.
■ Sizes 40–250 mm — Full Power Range Covered
Covers 0.12 kW (size 40) to 15.0 kW (size 250), with output torques from 5 Nm to 3,025 Nm — the complete range of standard OEM machine building and industrial conveyor drives.
WPDKA Worm Reducer — Industry Applications

⚒ OEM Compact Machine Design
Machine builders achieving the tightest possible drive envelope choose the WPDKA — IEC motor mounts direct, driven shaft inserts direct, and split cover provides maintenance access without disassembly.
⚙ Chemical & Wastewater Agitators
Agitator shafts insert through the hollow bore with no exposed coupling in corrosive process fluids. D-type housing enables annual worm wheel checks during routine maintenance windows without removing the motor.
⚊ Compact Conveyor Drive Packages
Shaft-mounted WPDKA with IEC motor reduces the installed height of conveyor head drive assemblies by eliminating adaptor and coupling components — critical in low-headroom installations.
⚙ Construction Equipment Drives
Robust FC20+ cast iron handles the shock loading of construction equipment drives. Triple-function design simplifies the drive system bill of materials for equipment manufacturers.
