WPEA 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。 WPEA 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。
Both reduction stages share a single FC20+ dual-chamber cast iron housing. No intermediate coupling shaft, no external m… 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.

WPEA Double Speed Worm Reducer — Core Features
■ Two Worm Stages in One Housing — No Intermediate Shaft
Both reduction stages share a single FC20+ dual-chamber cast iron housing. No intermediate coupling shaft, no external mounting frame between stages — the complete ultra-high-ratio reducer in a single bolt-down unit.
■ Ratio 1/200 to 1/900+ — Standard Motor Input
A standard 1,450 rpm motor input becomes 1.6–7.3 rpm at size 40–70 ratio 1/900. Covers the full ultra-low output speed requirement without custom gearing or planetary add-on stages.
■ Output Torque to 6,050 Nm — Size 155–250
The largest size combination (155–250 mm) delivers up to 6,050 Nm at the highest available ratio — matching the torque demands of heavy-duty solar tracker drives and large valve actuators.
■ Matched Tin-Bronze Worm Wheels — Both Stages
Both worm wheel pairs use the same ZCuSn10Pb1 tin-bronze alloy and precision hobbing process, ensuring consistent mesh efficiency and noise performance across the two-stage reduction.
■ 双边A型输入——标准电机联轴器
The A-type solid input shaft accepts standard motor couplings from either side. No special motor adaptor required — the WPEA installs with the same motor connection hardware as a standard WPA.
■ FC20+ Dual-Chamber Cast Iron Housing — Full Rigidity
The dual-chamber housing is machined from a single FC20+ casting to maintain precise inter-stage alignment. No bolted split between stages — the worm shaft centreline geometry is set permanently at manufacture.
WPEA Worm Reducer — Industry Applications
☀ Solar Tracker Drives
WPEA ratios from 1/500 to 1/900 reduce standard motor speed to the 1–5 rpm range required for photovoltaic panel tracking drives. Single-unit installation eliminates the multi-stage drive train complexity of alternative approaches.
⚒ Industrial Valve Actuators
Gate valves, butterfly valves, and sluice gates requiring ultra-low output speed and high output torque are standard WPEA applications. Size 100–155 at 1/800 delivers 2,100 Nm from a standard 3.69 kW motor input.
⚙ Slow-Speed Conveyor Drives
Cooling conveyors, curing conveyors, and controlled-rate feed systems requiring belt speeds below 0.1 m/s use WPEA double-stage reduction to achieve the necessary output speed without VFD controls.
☷ Antenna & Satellite Positioning
WPEA extreme-ratio reductions provide the fine angular control needed for large antenna and satellite dish positioning systems where backlash and ratio precision are both critical.

WPEA Double Speed Worm Reducer — Customer Reviews
“WPEA-80–135 on our solar tracker drives. Ratio 1/600 from a standard motor gives us exactly the panel rotation speed we need. One unit, one mounting frame, no intermediate coupling — clean installation.”
“Used WPEA on our industrial valve actuators. The 1/800 ratio from a small motor delivers the torque we need for large gate valves. Far simpler than the multi-stage drive system we previously used.”
“WPEA on our curing conveyor drives. Ultra-slow belt speed with standard motor input — no VFD needed. The dual-stage unit is more compact than the equivalent two-reducer configuration.”
“Good double-stage reducer for extreme ratio applications. WPEA-100–155 on our antenna positioning drives. Precise ratio, good torque. Would appreciate tighter backlash specification for demanding positioning applications.”
