WPEKA Double Speed Cast Iron Worm Reducer — WP Series

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. WPEKA 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.

The WPEKA combines the two-stage extreme ratio capability with the zero-coupling hollow bore output. The driven shaft in… 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.

■ K-Type Hollow Bore — Direct Shaft Mount at Ultra-High Ratio

The WPEKA combines the two-stage extreme ratio capability with the zero-coupling hollow bore output. The driven shaft inserts directly into the K-bore — no output coupling required even at 1/900+ ratios with 6,050 Nm output torque.

■ Shaft-Mount Configuration Available — Torque Arm Restraint

The hollow bore enables shaft-mounting the WPEKA directly onto the driven equipment shaft with a torque arm reaction bracket — the same installation method as the WPKA, but with access to ratios up to 1/900+.

■ Same 6,050 Nm Output Torque as WPEA — K-Bore Does Not Reduce Capacity

The K-type hollow bore substitution does not change the worm gear internals or torque ratings. WPEKA size 155–250 delivers identical 6,050 Nm to the WPEA at the same ratio.

■ Two-Stage Precision — Matched Worm Wheel Pairs Both Stages

Both worm wheel stages use precision-matched ZCuSn10Pb1 tin-bronze pairs, providing consistent inter-stage mesh quality. The dual-stage reduction noise level remains within the 68 dB(A) rated load limit.

■ Bilateral A-Type Input — Standard Motor Coupling

A-type solid input shaft accepts motor connections from either side via standard couplings. No motor adaptor required — WPEKA uses the same motor hardware as a standard WPA.

■ Foot-Mount or Shaft-Mount — Two Installation Modes

The WPEKA foot-mount base and torque arm boss are both present in the same housing. Use foot-mount for frame-mounted installation or shaft-mount directly onto the driven shaft — no modification required.

☀ Solar Tracker Shaft-Mount Drives

WPEKA shaft-mount configuration simplifies solar tracker structural design — the dual-stage reducer mounts directly on the tracker rotation shaft without a separate mounting frame, eliminating the frame and coupling between reducer and shaft.

⚙ Slow-Speed Conveyor Head Shaft Drives

For slow-speed conveyors with a keyed head shaft, WPEKA provides ultra-high ratio reduction plus direct shaft mounting — achieving output speeds below 5 rpm from a standard motor without VFD controls or external coupling hardware.

⚒ Large Valve Actuator Shaft Drives

WPEKA K-bore mounts directly on valve stem shafts for large valve actuator applications requiring ratios above 1/200. No coupling at the valve stem eliminates the external hardware most vulnerable to corrosion in outdoor installations.

⚊ Turntable & Indexing Platform Drives

The WPEKA hollow bore accommodates the central pivot shaft of large turntable and indexing platform drives, where extreme ratio reduction from a standard motor and direct shaft connection both simplify the mechanism.

■ 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.

“WPEKA on our solar tracker rotation shafts. Dual-stage reducer mounts directly on the tracker shaft — no separate frame, no coupling. 1/600 ratio from a standard motor. Clean, elegant installation.”

“Used WPEKA on our slow-speed cooling conveyor head shaft drives. Hollow bore on the head shaft, dual-stage for 1/500 ratio — belt speed exactly as required without VFD. Straightforward to install.”

“WPEKA shaft-mount on large valve actuator stems. No coupling at the valve stem level — eliminates the corrosion-prone hardware that was failing in our outdoor installation. Zero failures since changeover.”

“Good ultra-high ratio hollow bore unit. WPEKA-80–135 on our turntable drives. Direct shaft mount, 1/600 ratio, correct torque. Would appreciate a backlash specification for precision positioning assessment.”
