WPEKS 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。 WPEKS 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。
The WPEKS is the only WPE unit that simultaneously provides S-type overhead motor entry, K-type hollow bore output, and … 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.

WPEKS Double Speed Worm Reducer — Core Features
■ K+S+Double Stage — Three Functions: Overhead Motor + Hollow Bore + Extreme Ratio
The WPEKS is the only WPE unit that simultaneously provides S-type overhead motor entry, K-type hollow bore output, and two-stage extreme ratio reduction — the complete feature set for overhead-motor shaft-mount ultra-high-ratio drives.
■ S-Type Top Entry — Motor Overhead, Drive Compact
Overhead motor positioning minimises lateral machine width at extreme ratios where a side-entry motor would project beyond the structural envelope of compact machines and tracker frames.
■ K Hollow Bore — Direct Shaft Connection at 6,050 Nm
Hollow bore output connects the driven shaft directly even at 6,050 Nm maximum output torque (size 155–250). No output coupling hardware — shorter installed length, no coupling fatigue at extreme torque levels.
■ Shaft-Mount Capability — Torque Arm Restraint
The torque arm boss enables WPEKS shaft-mounting directly onto the driven equipment shaft — motor overhead, shaft through bore, no separate mounting frame. The most mechanically integrated configuration in the WPE series.
■ Dual-Stage Ratio to 1/900+ — Standard Motor, Ultra-Slow Output
9 rpm motor input (1,450 rpm / 1/900 / two stages) produces output shaft rotation well below 2 rpm without VFD controls. Single motor, single unit, no intermediate components.
■ Matched Dual-Stage Precision — Consistent Ratio at Both Stages
Both worm wheel stages are precision-matched at manufacture, ensuring inter-stage ratio accuracy is maintained across the service life — essential for positioning drives and solar tracker applications requiring repeatable angular positioning.
WPEKS Worm Reducer — Industry Applications

☀ Solar Tracker Overhead Motor Shaft-Mount
WPEKS shaft-mounts on the tracker rotation shaft with overhead motor entry — the most mechanically integrated solar drive configuration: no mounting frame, no coupling at either end, overhead motor fits within panel spacing.
⚙ Slow Conveyor Head Shaft Overhead Motor Drive
For narrow conveyor frames where the motor must be overhead and the head shaft is keyed, WPEKS provides direct shaft mounting and overhead motor in a single double-stage unit — output speeds below 3 rpm from standard motor.
⚒ Valve Actuator Shaft-Mount with Overhead Motor
Valve stem shaft insertion through WPEKS K-bore with overhead IEC motor coupling — eliminates both the adaptor plate and the output coupling from the actuator drive. Overhead motor keeps electrical connections above process fluid level.
⚊ Compact Turntable Drives — Overhead + Shaft Through
Central turntable pivot shaft passes through WPEKS hollow bore with the motor overhead — extremely compact turntable drive architecture achieving extreme ratio reduction in the minimum possible envelope.

WPEKS Double Speed Worm Reducer — Customer Reviews
“WPEKS on our solar tracker rotation shafts with overhead motor configuration. Shaft through K-bore, motor overhead via S-type coupling, 1/600 ratio — most compact tracker drive assembly we have designed. No mounting frame needed.”
“Used WPEKS on our narrow conveyor head shaft drives. Motor overhead within the frame width, hollow bore on the head shaft, 1/500 ratio. Output belt speed exactly right without VFD. Straightforward installation.”
“WPEKS on valve actuator drives with overhead motor requirement. Valve stem through K-bore, motor overhead via S coupling — no coupling hardware in the process area at all. Significant improvement over the previous arrangement.”
“Good K+S double-stage unit. WPEKS-70–120 on our turntable drives. Overhead motor, shaft through bore, 1/500 ratio — very compact installation. Would like a torque arm kit available as a standard accessory.”
