WPEDKA 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。 WPEDKA 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。
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.

WPEDKA Double Speed Worm Reducer — Core Features
■ 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.
WPEDKA Worm Reducer — Industry Applications
☀ 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.
