Pengurang Cacing Besi Tuang Berkelajuan Berganda WPEA — Siri WP

Pengurang cacing peringkat tunggal mencapai nisbah sehingga 1/60. Apabila aplikasi memerlukan 1/200, 1/500, atau 1/900 — penjejak solar, penggerak injap, penghantar berkelajuan perlahan dan pemacu kedudukan — peringkat cacing kedua ialah jawapan kejuruteraan. WPEA meletakkan dua peringkat cacing yang sepadan secara serentak dalam satu perumah besi tuang tunggal, memberikan nisbah dari 1/200 hingga lebih 1/900 dalam satu unit pemasangan kaki yang padat tanpa aci perantaraan, tiada gandingan luaran antara peringkat dan tiada rangka pemasangan tambahan.

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.

■ 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.

■ Bilateral A-Type Input — Standard Motor Coupling

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.

☀ 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.

■ Diperakui ISO 9001:2000 — Perhimpunan Dwi-Peringkat

Setiap unit berkelajuan dua WPE menjalani pengurusan kualiti ISO 9001:2000 pada kedua-dua peringkat pemasangan peringkat cacing. Penjajaran antara peringkat dan ketepatan nisbah gabungan disahkan sebelum pemasangan akhir.

■ Penandaan CE — Arahan Jentera EU 2006/42/EC

Pematuhan CE penuh untuk peralatan penghantaran kuasa mekanikal menyokong eksport ke pasaran EU, UK, Australia dan New Zealand tanpa pensijilan semula.

■ Ujian Pra-Penghantaran: Bunyi, Kebocoran, Tork

Bunyi bising di bawah 68 dB(A) pada beban undian, ujian kebocoran tekanan 30 minit pada kedua-dua ruang gear, dan tork output dalam lingkungan ±5% daripada undian. Unit yang tidak mematuhi piawaian diolah semula sebelum penghantaran.

■ Pensijilan Bahan FC20+ — Kedua-dua Perumah

Kedua-dua selongsong cacing primer dan sekunder disahkan oleh sijil kilang FC20: kekuatan tegangan minimum 220 MPa, kekerasan 160–200 HB. Ujian kecacatan ultrasonik pada kombinasi saiz 135–200 dan ke atas.

“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.”
