WPEDKA ダブルスピード鋳鉄製ウォーム減速機 — WPシリーズ

単段ウォーム減速機は最大1/60の減速比を実現します。1/200、1/500、または1/900の減速比が要求される用途（ソーラートラッカー、バルブアクチュエータ、低速コンベア、位置決め駆動装置など）では、2段目のウォーム減速機が技術的な解決策となります。 WPEDKA 2つのマッチングされたウォームギアを単一の鋳鉄製ハウジング内に直列に配置し、中間軸、ステージ間の外部カップリング、追加の取り付けフレームを必要とせず、コンパクトな脚部取り付けユニットで1/200から1/900を超える減速比を実現します。

D-split maintenance access, IEC direct motor mount, K hollow bore output, and two-stage extreme ratio — all within a sin… The dual-stage architecture uses matched tin-bronze worm wheels and 20CrMnTi worm shafts at both stages, providing consistent mesh quality and noise performance across the full ultra-high ratio range.

■ Four Functions in One Dual-Stage Housing

D-split maintenance access, IEC direct motor mount, K hollow bore output, and two-stage extreme ratio — all within a single FC20+ cast iron dual-chamber housing. The most fully specified unit in the WPE double speed series.

■ IEC Motor Flange — Direct Motor Mount at 1/200–1/900+

Motor bolts directly onto the first-stage IEC flange. No adaptor plate, no coupling between motor and first stage. Simplifies OEM motorised drive BOM at all ultra-high ratio levels.

■ K Hollow Bore — No Output Coupling at 9,066 Nm Maximum

The K-type output bore receives the driven shaft directly even at maximum output torques up to 9,066 Nm (size 155–250). No coupling hardware required at the output shaft interface.

■ D-Split Housing — Dual-Stage In-Situ Access

Remove the housing cover without disturbing motor or driven shaft connections. Both worm stage chambers are accessible for worm wheel inspection and replacement in-situ — minimising planned maintenance time for installed motorised drive systems.

■ Replaces Four Components — Reducer + IEC Adaptor + Output Coupling + Second Frame

WPEDKA eliminates the IEC motor adaptor, the output shaft coupling, and the inter-stage coupling and frame required by two separate single-stage reducers. Single unit, minimum installation hardware.

■ Matched Dual-Stage Worm Wheel Pairs — Consistent Ratio Accuracy

Both stage worm wheel pairs are precision-matched at manufacture. Inter-stage ratio accuracy is maintained across the full operating life — critical for positioning drives where accumulated ratio error must remain within specification.

☀ Solar & Renewable Energy Motorised Drives

WPEDKA direct IEC motor flange and hollow bore output simplify solar tracker and wind turbine yaw drive design — no adaptor, no coupling at either end, in-situ service access for the expected 20+ year field life.

⚒ Electric Valve Actuator Systems

IEC motor direct coupling and K-bore valve stem mounting eliminates both motor adaptor and output coupling from electric actuator assemblies. D-split cover provides in-situ valve actuator inspection access.

⚙ Industrial Positioning Drive Systems

For CNC rotary table indexing, large-format precision turntable drives, and automated gate positioning systems, WPEDKA extreme ratio plus direct connections at both ends simplifies the drive train architecture.

⚊ Shaft-Mounted High-Ratio Conveyor Drives

Shaft-mount WPEDKA directly on conveyor head shafts for extreme-ratio, ultra-slow-speed conveyor drives — IEC motor overhead, hollow bore on shaft, no coupling hardware anywhere in the drive train.

■ ISO 9001:2000認証取得済み — 二段階組立

WPEの二段変速ユニットはすべて、ウォーム段組立段階の両方においてISO 9001:2000品質管理基準に準拠しています。最終組立前に、段間アライメントと複合減速比の精度が検証されます。

■ CEマーキング — EU機械指令2006/42/EC

機械式動力伝達機器のCEマーク完全準拠は、再認証なしでEU、英国、オーストラリア、ニュージーランド市場への輸出を可能にします。

■ 出荷前テスト：騒音、漏れ、トルク

定格負荷時の騒音は68dB(A)以下、両ギア室の30分間加圧漏れ試験に合格、出力トルクは定格値の±5%以内。不適合品は出荷前に再加工。

■ FC20+ 材料認証 — 両方のハウジング

一次および二次ウォームハウジングは、FC20ミル証明書によって検証されています。最低引張強度は220MPa、硬度は160～200HBです。サイズ組み合わせ135～200以上については、超音波欠陥検査を実施しています。

“WPEDKA on our solar tracker motorised drives. IEC motor direct, K-bore on tracker shaft, D-split for 20-year field maintenance plan. No coupling hardware anywhere in the drive — exactly what the system design required.”

“Used WPEDKA on our industrial valve actuator assemblies. Eliminated IEC adaptor, output coupling, and second reducer frame from the BOM. Single unit at 1/800 ratio with 2,100 Nm output. Remarkable simplification.”

“WPEDKA on our precision turntable positioning drives. Direct IEC motor, shaft through K-bore, split cover for annual inspection. Most compact drive architecture we’ve achieved for this application.”

“Excellent integration unit. WPEDKA-80–135 on our conveyor positioning drives. All four features working as described. Would appreciate a formal backlash specification for use in our positioning accuracy calculations.”
