WPEDA 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。 WPEDA 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。
Integrates the IEC motor flange directly into the first stage of the dual-chamber housing. Motor bolts on in four bolts … 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.

WPEDA Double Speed Worm Reducer — Core Features
■ IEC Motor Flange on Dual-Stage Housing — No Adaptor
Integrates the IEC motor flange directly into the first stage of the dual-chamber housing. Motor bolts on in four bolts — no adaptor plate, no coupling, no alignment — across the full 1/200–1/900+ ratio range.
■ D-Type Split Housing — In-Situ Access to Both Stages
The D-type split line enables the housing cover to be removed without disturbing the motor or driven machine. Both worm stage chambers are accessible for inspection and service in-situ — critical for planned maintenance on installed solar or valve actuation systems.
■ Output Torque to 9,066 Nm — Size 155–250 with IEC Input
WPEDA size 155–250 delivers up to 9,066 Nm from a 5.5 kW IEC-flanged motor at the highest available ratio — the largest output torque in the WPE series.
■ Matched Dual-Stage Tin-Bronze Worm Wheels
Both reduction stages use precision-matched ZCuSn10Pb1 tin-bronze worm wheel pairs, calibrated for consistent inter-stage ratio accuracy across the 1/200–1/900+ range.
■ One Unit Replaces Reducer + IEC Adaptor — Fewer BOM Items
WPEDA replaces the gearbox plus the IEC motor adaptor plate. In OEM ultra-high-ratio drive systems, eliminating the adaptor reduces component count, installed length, and assembly time.
■ FC20+ Dual-Chamber Housing — Thermally Stable at 95°C
The single-cast dual-chamber FC20+ housing maintains inter-stage alignment at operating temperature. No bolted joint between stages means thermal expansion does not cause relative shaft displacement.
WPEDA Worm Reducer — Industry Applications
☀ Motorised Solar Tracker Systems
WPEDA IEC motor flange enables direct motor attachment on solar tracker drive units. 1/600–1/900 ratios achieve panel rotation speeds below 2 rpm from standard 4-pole motors without VFD controls.
⚒ Electric Valve Actuator Drives
Direct IEC motor coupling at ratios to 1/900+ provides the torque multiplication needed for large-diameter industrial valve actuation — eliminating the motor adaptor from the electric actuator BOM.
⚙ Low-Speed Industrial Mixers
Large industrial mixing vessels requiring output shaft speeds below 2 rpm use WPEDA dual-stage reduction with direct IEC motor — compact, direct-drive architecture versus multi-stage reducer trains.
⚊ Automated Gate & Barrier Systems
WPEDA high-ratio reduction from a compact IEC motor drives automated gates, dam sluices, and industrial barrier systems where torque, slow speed, and direct motor connection are all required.
