描述

WPES 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。 WPES 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。

Combines two worm stages with S-type top-entry input, enabling the motor to mount overhead while achieving ratios that n… 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.

WPES Double Speed Worm Reducer — Core Features

■ S-Type Top-Entry + Double Stage — Overhead Motor at 1/200–1/900+

Combines two worm stages with S-type top-entry input, enabling the motor to mount overhead while achieving ratios that no single-stage reducer can reach. Reduces lateral machine footprint at ultra-high ratio.

■ Same Torque Ratings as WPEA — S Input Does Not Reduce Capacity

S-type top-entry designation changes input shaft direction only. WPES worm gear internals and torque ratings are identical to the WPEA — up to 6,050 Nm from size combination 155–250.

■ Matched Dual-Stage Worm Wheels — Both Stages

Both reduction stages use precision-matched ZCuSn10Pb1 tin-bronze worm wheel pairs for consistent inter-stage ratio accuracy across the full 1/200–1/900+ range.

■ Overhead Motor Reduces Lateral Footprint

S-type input positions the motor vertically above the dual-stage reducer. In confined-width installations where lateral motor projection would exceed available space, WPES resolves the constraint without sacrificing ratio capability.

■ Bilateral Input Option Maintained

The S-type top-entry input shaft extends on both sides, accepting coupling connections from either direction — the same flexibility as the standard WPS single-stage unit.

■ FC20+ Dual-Chamber Cast Iron Housing

Single-cast dual-chamber housing from FC20+ grey cast iron maintains inter-stage alignment across the operating temperature range. No bolted joint between stages — worm shaft centreline geometry is set at manufacture.

WPES Worm Reducer — Industry Applications

WPES double speed worm reducer ultra-high ratio industrial applications

☀ Overhead-Motor Solar Tracker Drives

WPES combines ultra-high ratio reduction with overhead motor geometry — reducing the lateral projection of the drive assembly on solar tracker frames where horizontal space between panels is constrained.

⚒ Valve Actuators in Tight Lateral Spaces

In pipe galleries and valve manifolds where lateral clearance beside the actuator drive is limited, WPES overhead motor positioning achieves the required 1/200–1/900+ ratio within the available installation envelope.

⚙ Slow-Speed Drives in Narrow Machine Frames

Machinery with constrained lateral width — narrow conveyors, slim elevator frames, compact processing lines — uses WPES to achieve ultra-high ratio reduction while keeping the motor above the frame rather than beside it.

⚊ Overhead-Driven Positioning Systems

Where the mechanical design requires the motor to be above the driven equipment and the output speed must be below 5 rpm, WPES is the standard double-stage solution.

WPES Double Speed Worm Reducer — Customer Reviews

★★★★★

“WPES on our solar panel tracker drives where horizontal clearance between panel arrays is limited. Overhead motor plus 1/600 ratio gives us the tracking speed we need in a narrower drive envelope than the WPEA configuration.”

Townsville — G.H.
★★★★★

“Used WPES on our narrow-frame conveyor drives. Motor overhead keeps the drive within the frame width. 1/500 ratio gives us correct belt speed from a standard 4-pole motor. Good solution.”

Perth — B.S.
★★★★★

“WPES on valve actuator drives in our pipe gallery. Limited lateral clearance made WPES the only workable option. Overhead motor, 1/800 ratio, correct torque output for the valve size. Works well.”

Singapore — D.C.
★★★★☆

“Good S-type double-stage unit for overhead motor applications. WPES-80–135 on our positioning drives. Overhead motor reduces machine width. Would appreciate a combined S+K variant for shaft-mount applications.”

Frequently Asked Questions — WPES Double Speed Worm Reducer

▶ How does WPES differ from WPEA?
The WPEA accepts the motor shaft from below (A-type). The WPES accepts it from above (S-type), positioning the motor overhead. Both have identical two-stage worm gear internals, the same ratio range, and the same torque ratings — only the input shaft direction differs.
▶ What is the oil volume adjustment for WPES S-type input orientation?
With the input shaft entering from above, the first-stage worm shaft orientation shifts. Use the WPES-specific lubrication table for the correct oil volume in each chamber at the specified size combination and S-type mounting orientation.
▶ Can a standard motor couple to the WPES S-type input shaft?
Yes. The WPES S-type input shaft accepts standard IEC motor shaft couplings. The shaft dimensions are identical to the WPS single-stage unit — any coupling designed for WPS input shaft dimensions fits WPES.
▶ Does WPES support shaft-mount configuration?
The WPES standard configuration uses foot-mount. For shaft-mount applications combining double-stage reduction with overhead S-type input and hollow bore output, the WPEKS model (K+S+double-stage) is the appropriate choice.
▶ What is the maximum output torque for WPES?
WPES size combination 155–250 delivers up to 6,050 Nm — identical to WPEA at the same size combination and ratio. S-type input designation does not affect the worm gear torque capacity.
