WPWDK Worm Reducer — Core Features

■ Four Features: Universal Body + IEC + K-Bore + D-Split

Universal P-housing with direct IEC motor mounting, K hollow bore coupling-free output, and D-split in-situ maintenance cover — zero coupling hardware at either end in any WPW shaft direction.

■ IEC Flange — No Adaptor at Any Shaft Direction

IEC 72-1 flange at the input stage eliminates the motor adaptor across all 5 WPW shaft direction configurations.

■ K Hollow Bore — Coupling-Free Shaft Insertion at Any Orientation

K-type through-bore accepts the driven shaft directly at any WPW output shaft direction — no coupling, no coupling maintenance, no coupling fatigue in any orientation.

■ D-Split Cover — In-Situ Access in Any Configuration

Cover removes for worm wheel inspection in any WPW shaft direction — universal maintenance access across all installation orientations.

■ Single Product — All Motorised Hollow Bore Drive Positions

WPWDK eliminates the need for direction-specific motorised hollow bore reducer variants — one product model covers all installation orientations.

■ Output Torque 2.2–4,440 Nm — Full Capacity Retained

Four features do not affect worm gear torque ratings. WPWDK size 250 delivers 4,440 Nm — the same as WPW.

WPWDK Worm Reducer — Industry Applications

Frequently Asked Questions — WPWDK Universal Speed Worm Reducer

▶ How does WPWDK differ from WPWK?
The WPWK uses a standard bilateral solid input shaft requiring coupling and a solid one-piece housing. The WPWDK adds IEC motor flange for direct motor mounting and D-split housing for in-situ maintenance. Same shaft direction options, same torque ratings, same hollow bore.
▶ What is the maximum output torque for WPWDK?
WPWDK size 250 delivers up to 4,440 Nm — the same as WPW and WPWK since the worm gear internals are identical.
▶ Can WPWDK be shaft-mounted in any orientation with IEC motor?
Yes. The torque arm boss is present regardless of WPW shaft direction. With IEC motor connected overhead and K-bore on the driven shaft, WPWDK is shaft-mounted with zero external coupling hardware at either end.
▶ Does the D-split cover open in any WPW shaft direction?
Yes. The D-split design allows cover removal regardless of WPW shaft direction configuration — universal in-situ maintenance access.
▶ What IEC motor frames does WPWDK accept?
Same as WPWD: A02/Y-series at the same frame ranges per size. Verify motor dimensions against WPWDK dimension drawing.
