WPEDX Double Speed Cast Iron Worm Reducer — WP Series

Ceiling-mounted slow-speed drive applications require extreme ratio reduction, direct motor mounting, and maintenance access in-position simultaneously. The WPEDX provides all four: the IEC motor flange eliminates the adaptor plate, the X-type output shaft points downward for the driven equipment below, the D-split cover opens in the ceiling-mount position for worm wheel inspection, and the dual worm stages achieve ratios from 1/200 to 1/900+.

■ IEC Flange + X Downward + D-Split + Double Stage — Complete Inverted Motorised Drive

The WPEDX delivers four functions simultaneously: direct IEC motor mount (no adaptor), X-type vertical downward output, D-split in-situ maintenance cover access, and two-stage extreme ratio reduction — the complete solution for motorised ceiling-mount ultra-slow drives.

■ D-Split Housing — Ceiling-Position Worm Wheel Access

Remove the housing cover in the inverted ceiling-mount position without disturbing motor or output shaft connections. Both worm stage chambers are accessible in-situ for planned maintenance.

■ Output Torque to 9,066 Nm — D+X Does Not Reduce Capacity

WPEDX worm gear internals are identical to WPEDA. D+X configuration affects mounting and output direction only — torque capacity is unchanged.

■ IEC 72-1 Flange — Direct Motor Mount on Ceiling Structure

Motor bolts on in four bolts in the inverted ceiling-mount position. IEC flange accuracy ensures permanent motor-reducer alignment even in sustained inverted load conditions.

■ Independent Oil Chambers for X-Type Inverted Orientation

Both chambers use X-type adjusted oil volumes from the WPEDX lubrication table. Independent fill, gauge, and drain for each stage.

■ FC20+ Dual-Chamber Cast Iron — Inverted Structural Stability

FC20+ grey cast iron maintains dimensional stability under sustained inverted mounting loads — the housing does not deform or creep under the weight of the unit and motor in ceiling-mount configuration.

⚊ Mining Overhead Conveyor Slow Drives + Maintenance

WPEDX ceiling-mount combines IEC direct motor, X-type downward shaft for the conveyor head, and D-split inspection access in position — the complete overhead mining drive solution that WPEX provides plus in-situ maintenance access.

⚒ Overhead Automated Gate Drives

Ceiling-mounted automated sluice gate and industrial barrier drives requiring direct IEC motor, extreme ratio, downward shaft output, and periodic gear inspection — WPEDX provides all four requirements.

☵ Sub-Floor Mechanism Drives — In-Situ Accessible

Extreme ratio ceiling drives for sub-floor conveyor and indexing mechanisms where planned maintenance access in-position is required in addition to direct motor mounting and downward output shaft.

⚛ Industrial Overhead Hoist Auxiliary Drives

Auxiliary drives for overhead industrial hoists and crane traversal systems requiring extreme ratios and direct IEC motor, ceiling-mount, with periodic gearbox inspection access in position.

■ ISO 9001:2000 — Dual-Stage Assembly Certified

Both worm stage assemblies are manufactured and tested under ISO 9001:2000. Inter-stage alignment and ratio accuracy are verified before final assembly of every unit.

■ نشان CE — دستورالعمل ماشین‌آلات اتحادیه اروپا 2006/42/EC

Full CE compliance for export to EU, UK, Australian, and New Zealand markets without re-certification.

■ آزمایش‌های قبل از حمل و نقل: نویز، نشتی، گشتاور

Noise below 68 dB(A) at rated load, 30-minute pressurisation of both gear chambers, and output torque within ±5% of rated. Non-conforming units reworked before shipment.

■ گواهینامه مواد FC20+

Both housings carry FC20 mill certificates: 220 MPa minimum tensile strength, 160–200 HB hardness. Ultrasonic testing on size combinations 135–200 and above.

“WPEDX on ceiling-mounted mining conveyor drives. IEC motor direct, downward shaft to conveyor head, D-split cover opens for inspection from below while unit stays on ceiling structure. Eliminated scaffolding requirements for annual maintenance.”

“WPEDX-100–155 on our overhead automated gate drives. Direct IEC motor at 1/800 ratio, 2,100 Nm output, downward X-type shaft. Split cover accessible in position. Exactly right for our installation.”

“Used WPEDX on sub-floor mechanism drives at our distribution centre. Ceiling mount, downward output through floor, D-split for scheduled inspection without lowering the unit. Significant maintenance time saving.”

“Good D+X+double-stage combination. WPEDX-80–135 on our ceiling-mounted hoist auxiliaries. All features working as specified. Would like independent chamber pressure-test documentation for our safety case.”
