WPEDS Double Speed Cast Iron Worm Reducer — Product Overview
单级蜗轮减速器可实现高达 1/60 的减速比。当应用需要 1/200、1/500 或 1/900 的减速比时——例如太阳能跟踪器、阀门执行器、低速输送机和定位驱动器——则需要采用第二级蜗轮减速器。 WPEDS 将两个匹配的蜗杆级串联安装在一个铸铁外壳中，在一个紧凑的底座安装装置中提供 1/200 到 1/900 以上的传动比，没有中间轴，级间没有外部联轴器，也没有额外的安装框架。
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.

WPEDS Double Speed Worm Reducer — Core Features
■ 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.
WPEDS Worm Reducer — Industry 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.
