WPEDKS 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。 WPEDKS 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, S-type overhead IEC motor flange, K hollow bore output, and two worm stages. The most fully … 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.

■ Five Features in One Dual-Stage Housing

D-split maintenance access, S-type overhead IEC motor flange, K hollow bore output, and two worm stages. The most fully specified unit in the entire WP series — eliminating motor adaptor, output coupling, inter-stage coupling, and second mounting frame simultaneously.

■ IEC Motor Overhead — No Adaptor, No Lateral Projection

S-type IEC flange accepts the motor from directly above. No adaptor plate, no lateral motor projection — the minimum possible motorised drive height and width at extreme ratios.

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

K-type hollow bore receives the driven shaft at output torques up to 9,066 Nm (size 155–250). No output coupling hardware at any torque level across the 1/200–1/900+ ratio range.

■ D-Split Housing — In-Situ Access, Motor and Shaft Stay Connected

Both worm stage chambers accessible via split cover removal while the overhead IEC motor and the driven shaft remain connected. The lowest planned maintenance effort in the WPE series for installed ultra-high-ratio drives.

■ Replaces Five Components — Single Unit Solution

WPEDKS replaces: dual-stage reducer + IEC adaptor plate + output coupling + inter-stage coupling + second reducer mounting frame. Zero external coupling hardware at either end, one foot-mount base.

■ Matched Dual-Stage Worm Wheels — 20+ Year Ratio Accuracy

Precision-matched worm wheel pairs at both stages maintain inter-stage ratio accuracy across the extended service intervals of solar, infrastructure, and industrial automation installations.

☀ Maximum-Integration Solar Tracker Drives

WPEDKS provides the lowest component-count solar tracker drive solution: overhead IEC motor, shaft-through-bore connection to the tracker rotation shaft, in-situ D-split inspection access — designed for 20+ year field life with minimum maintenance visits.

⚒ Industrial Valve & Gate Actuator Systems

For valve and gate actuator OEMs specifying direct IEC motor, extreme ratio, shaft-mount output, and validated in-situ inspection capability simultaneously — WPEDKS is the reference unit combining all four requirements.

⚙ Positioning Drive Systems — Extreme Ratio + Direct Connections

Automated turntable, large-format rotary axis, and industrial gantry positioning drives requiring ratios above 1/200 with direct connections at both input and output ends — WPEDKS delivers all requirements in one compact foot-mount unit.

⚊ Overhead Shaft-Mount Conveyor Drives

Overhead motor geometry, hollow bore on the conveyor head shaft, dual-stage extreme ratio from a standard motor, and periodic gear mesh inspection in-situ — WPEDKS is the complete solution for space-constrained overhead slow-speed conveyor applications.

■ 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。

“WPEDKS on our solar tracker shaft drives. IEC motor overhead, K-bore on tracker shaft, D-split for annual field inspection — zero external coupling hardware anywhere. The cleanest drive design we have used in 15 years of tracker installations.”

“WPEDKS on industrial valve actuator assemblies. Direct overhead IEC motor, shaft through K-bore, split cover inspection without motor or valve disconnection. Five functions — one unit. Eliminated three BOM lines per installation.”

“Used WPEDKS on our slow-speed conveyor head shaft drives with overhead motor constraint. 1/600 ratio, K-bore on head shaft, motor overhead, D-split for periodic inspection — everything required in one compact unit.”

“Outstanding five-feature integration. WPEDKS-80–135 on our precision turntable drives. All features operational as specified. Would appreciate a formal backlash specification and an available torque arm accessory kit.”
