Червячный редуктор WPDKA для односкоростных передач из чугуна — серия WP

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.

■ 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.

⚒ 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.

■ Сертифицировано по стандарту ISO 9001:2000

Каждое изделие производится в соответствии со стандартом управления качеством ISO 9001:2000. Проверка сырья, контроль качества на всех этапах производства и окончательное тестирование документируются и отслеживаются по серийному номеру каждого изделия.

■ Маркировка CE — Директива ЕС о машиностроении 2006/42/EC

Полное соответствие стандартам CE подтверждает приверженность европейским стандартам безопасности и проектирования механических систем передачи энергии, что способствует экспорту на рынки ЕС, Великобритании, Австралии и Новой Зеландии.

■ Предпродажные испытания: шум, герметичность, крутящий момент

Каждый агрегат проходит три испытания перед отгрузкой: уровень шума ниже 68 дБ(А) при номинальной нагрузке, 30-минутное испытание на герметичность под давлением и передачу крутящего момента в пределах ±5% от номинального значения. Несоответствующие агрегаты дорабатываются, но не отгружаются.

■ Сертификация материалов FC20+

Корпуса отливок проверяются по заводским сертификатам на соответствие марке FC20: минимальная прочность на растяжение 220 МПа, твердость 160–200 HB. Ультразвуковой контроль дефектов проводится для типоразмеров 135 и выше.

“WPDKA eliminated three separate components from our mixer drive BOM — motor adaptor, gearbox, and output coupling. Assembly time per unit dropped from 45 minutes to 12 minutes.”

“Used WPDKA-120 on our packaging line drives. Direct motor flange and hollow bore output gave us the most compact drive envelope we’ve achieved. No alignment issues after 12 months continuous running.”

“WPDKA on our sewage treatment agitators. Split housing made our first annual inspection very fast — full access with motor in-place. Worm wheel in excellent condition after 9,000 hours.”

“Very good multi-function unit. The DKA combination is exactly what our compact OEM conveyor design needed. Would welcome a larger selection in the 155–200 mm range.”
