Червячный редуктор WPA для односкоростной передачи, чугунный, серия WP.

Он WPA is the benchmark foot-mount worm reducer in the WP series, chosen where engineers need a rugged, standard-dimension drive unit that installs directly into existing conveyor frames, agricultural machinery, and industrial processing equipment. The FC20+ grey cast iron housing delivers inherent vibration damping under sustained loads up to 2,371 Nm, supporting 50,000+ hour service life across continuous-duty applications.

Its defining feature — a bilateral input shaft — accepts motor connection from either side without ordering a mirrored unit, eliminating adaptor brackets and simplifying installation on compact machine frames. 12 standard sizes from 40–250 mm centre distance cover 0.12–33.20 kW input power across the full range of standard motor frames.

■ FC20+ Cast Iron — 3× Vibration Damping vs Aluminium

Precision-machined FC20+ grey cast iron absorbs shock loads that would fatigue aluminium housings, extending bearing life in conveyor and agricultural applications with high-vibration duty cycles.

■ Bilateral Input Shaft — Motor from Either Side

Both ends of the worm shaft are accessible on every WPA, allowing left- or right-hand motor connection without a mirrored unit. Reduces installation time and eliminates custom bracket fabrication on confined machine frames.

■ 12 Sizes: 17 Nm to 2,371 Nm Output Torque

From compact 40 mm units at 17–26 Nm to heavy-duty 250 mm units at 1,881–2,371 Nm, a single WPA series covers the entire range of standard conveyor, pump, and agricultural drive requirements.

■ Four Mounting Orientations Without Hardware Changes

B3 horizontal, B6 output-up, B7 output-down, and B8 reverse — all supported without modification. Adjust oil quantity per orientation per the lubrication chart.

■ 20CrMnTi Worm Shaft at 55–60 HRC

The carburised, precision-ground worm shaft maintains mesh geometry over 50,000+ hours. Noise level remains below 68 dB(A) at rated load across the full 1/5–1/60 ratio range.

■ Oil Gauge + Drain Plug Standard

Every WPA includes an oil level sight glass and bottom drain plug as standard. First oil change at 100 hours (run-in), then every 2,500 hours — a 15-minute task requiring no specialist tools.

⚊ Grain Auger & Conveyor Drives

The WPA foot-mount base installs directly into standard conveyor frame bolt patterns. Sizes 100–135 at 1/20–1/40 ratios are the standard choice for grain auger drives, where 24/7 harvest-season operation demands cast iron durability over lighter alternatives.

☷ Agricultural Machinery

Powers seed drills, slurry spreaders, and irrigation pump drives. The bilateral input shaft allows motor positioning on either machine side without custom brackets — reducing OEM build time per machine.

⚒ Packaging & Bottling Lines

WPA-60 to WPA-100 deliver precise speed reduction for carton formers, labelling conveyors, and palletiser turntables. Operation below 68 dB(A) meets food factory noise floor requirements.

⚙ Pump & Fan Drives

Continuous 95°C oil temperature rating suits pump station and HVAC fan applications where full-load operation is continuous rather than intermittent.

■ 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.

“WPA-100 running on our grain auger drives for 18 months — zero failures across 12 units in a dusty, high-vibration environment. The cast iron housing handles impacts that would crack aluminium.”

“Replaced worn units with WPA-80 on our packaging conveyor. Noise dropped from 74 dB to under 68 dB. Bilateral shaft meant no motor rewiring — saved two hours per unit during the changeover.”

“WPA-135 on our irrigation pump at 24/7 for over 14,000 hours with no leaks. The oil gauge boss makes monthly level checks a 30-second task.”

“Good performance on our bottling line. WPA-60 runs quietly in B6 vertical mount on a compact frame. Would appreciate more sizes between 135 and 155 mm.”
