WPEDS 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。 WPEDS 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。

IEC motor flange at the S-type overhead position enables direct motor mounting above the dual-stage housing. No adaptor … 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.

■ S-Type IEC Flange Overhead + Double Stage — Maximum Ratio from Direct Motor

IEC motor flange at the S-type overhead position enables direct motor mounting above the dual-stage housing. No adaptor plate between motor and first stage, no lateral motor projection — the most compact motorised ultra-high-ratio drive in the WPE series.

■ D-Split Housing — Dual-Stage Maintenance Access in Position

Top cover removes with motor mounted overhead and driven shaft connected. Both worm stage chambers accessible in-situ — no unit removal required for planned maintenance intervals.

■ Output Torque to 9,066 Nm — Same as WPEDA

WPEDS worm gear internals are identical to WPEDA. S-type IEC input direction does not reduce the dual-stage torque capacity — size 155–250 delivers up to 9,066 Nm.

■ Most Compact Overhead Motorised Ultra-High-Ratio Drive

Combining overhead IEC motor (S-type), split maintenance access (D-type), and two-stage extreme ratio in one housing achieves the minimum possible installed height and lateral width for a motorised reducer at ratios above 1/200.

■ Dual Independent Oil Chambers

Both gear stage chambers are independently sealed, independently filled, and independently drained. Separate oil condition monitoring per stage simplifies planned maintenance in long-interval applications such as solar and infrastructure drives.

■ FC20+ Dual-Chamber Housing — 20+ Year Service Life Capability

FC20+ cast iron dual-chamber housing maintains inter-stage alignment and dimensional stability across the extended service intervals required by infrastructure, renewable energy, and industrial automation applications.

☀ Overhead-Motor Solar Tracker + Maintenance Access

WPEDS combines overhead IEC motor (eliminating lateral drive projection on tracker frames) with D-split maintenance access — critical for solar installations where periodic inspection must occur in-situ on the mounting structure.

⚒ Compact Valve Actuator Drives with Service Access

In valve actuator applications where both minimal lateral projection and in-situ periodic inspection are required, WPEDS is the appropriate WPED series choice — overhead motor, extreme ratio, in-situ worm wheel access.

⚙ Automated Gate & Dam Sluice Drives

WPEDS motorised overhead configuration suits gate and sluice drives where the motor must be above the water level and periodic drive inspection must occur without removing the unit from the water control structure.

⚊ Industrial Automation Positioning Drives

High-ratio positioning drives for large rotary tables, industrial gantries, and automated handling systems benefit from WPEDS overhead IEC motor and in-situ split cover access for precision gear mesh inspection.

■ 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。

“WPEDS on our solar tracker motorised drives. Overhead IEC motor keeps the drive assembly within the panel spacing constraint. D-split cover for in-situ inspection at the annual maintenance interval — critical for field-installed units.”

“Used WPEDS on our dam sluice gate drives. Motor overhead above water level, 1/900 ratio, 4,463 Nm output. D-split cover opens for inspection without removing the unit from the gate frame. Exactly the design we needed.”

“WPEDS on our compact automated gate positioning drives. Overhead IEC motor direct mount, split maintenance access in position — reduced planned downtime for our annual inspection schedule by 60% versus the previous drive arrangement.”

“Good overhead IEC + dual-stage combination. WPEDS-100–155 on our industrial turntable drives. Overhead motor, extreme ratio, in-situ access — all working as specified. Appreciate independent oil chambers.”
