Engineering Features of the Silage Gearbox

Each of the cards below describes a specific, measurable attribute of the EP-QZ-WRXL unit. Generic claims have been kept out — every number here is tied to a manufacturing process or a verified test result.

Bunyi & Getaran Rendah
Gear digiling CNC mengikut ISO 1328 kelas 6. Bunyi tanpa beban kekal di bawah 72 dB(A); set rotor diseimbangkan dinamik kepada G6.3, jadi alat berjalan lancar walaupun pada kelajuan PTO penuh.
Pelinciran Mod Dwi
Flinger dalaman mengalirkan minyak ke atas galas atas; jaringan bawah mengalir dalam mandian minyak terkawal. Tingkap paras minyak yang jernih serta palam longkang magnetik menjadikan penyelenggaraan lapangan cepat.
Kawalan Tindak Balas yang Tepat
Pasangan gear dipasang dalam jig yang menahan tindak balas sehingga ±0.02 mm. Bunyi larian kekal rendah dan sentuhan gigi kekal di tengah, memanjangkan hayat perkhidmatan.
️ Tingkap Operasi Lebar
Diuji dari -25 °C hingga +85 °C dengan minyak GL-5 sintetik. Unit ini dihidupkan dengan bersih pada pagi yang sejuk dan tahan lasak di ladang musim panas yang terbakar matahari tanpa kegagalan pengedap.
️ Anti-Corrosion Finish
Outer surfaces receive a zinc-phosphate base then a baked epoxy topcoat to 80 µm thickness. Salt-spray resistance ≥ 480 hours, important for high-speed duty.
Field-Repairable Design
Bolted end-covers and standardized seal sizes mean a worn shaft seal or output bearing can be replaced on the farm with hand tools — no return-to-factory delay.
Flange Compatibility
Multiple bolt-circle patterns are stocked: 100 × 100 mm square, BCD 130 mm round, and ISO 9409-A. Replacement onto existing implements normally requires no adapter.
⏱️ Run-In Tested
Every assembled gearbox runs on a no-load test stand for 30 minutes minimum to confirm bearing pre-load, oil retention, and acoustic signature before packing.

How to Select the Right Silage Gearbox

Use the three-step approach below to match a EP-QZ-WRXL-class unit to your tractor and implement.

  1. Ukur — rekodkan standard PTO traktor anda (540/1000 RPM, kiraan spline), diameter dan panjang aci input alat, dan corak bolt yang tersedia pada muncung alat.
  2. Padanan — cross-check those measurements against the spec table for the EP-QZ-WRXL. The flange, shaft, and ratio need to all line up before moving on.
  3. Sahkan di bawah beban — sahkan kuasa input dan tork output yang dinilai mencukupi untuk keadaan operasi puncak anda (cth. tanah basah, tanaman padat, permulaan sejuk).

Senarai semak kriteria pemilihan

Kriteria pemilihan Titik keputusan
Jenis pelaksanaan → padanan nisbah For silage disc mower / forage harvester, target gear ratio in the 1:1.5 – 1:2 range for correct rotor or output speed.
Jalur kuasa traktor Match input power rating to your tractor: 70–180 HP is the practical envelope for the EP-QZ-WRXL family.
Kelajuan PTO (540 lawan 1000 RPM) 540 RPM adalah standard pada traktor di bawah 100 HP; 1000 RPM adalah lebih baik pada mesin 100+ HP dan di mana kelajuan output yang lebih tinggi diperlukan. Sahkan output PTO traktor sebelum menentukan.
Bahan perumahan Besi tuang (HT250 / QT500) untuk tugas berterusan yang berat; aloi aluminium yang memerlukan pengurangan berat dan pelesapan haba yang cepat, contohnya peralatan kecil yang kerap digerakkan.
Susun atur Unit sudut kanan (90°) mengalihkan kuasa PTO ke aci kerja serenjang; unit sebaris mengekalkan penjajaran aci. Pilih berdasarkan geometri pelaksanaan.
Standard vs tersuai Model standard meliputi sebahagian besar kedudukan OEM. Untuk nisbah bukan standard, hujung aci khas, bebibir bersaiz besar atau spesifikasi persekitaran yang keras, minta binaan tersuai.
Antara muka hujung aci Sahkan piawaian PTO input (6-spline, 21-spline, 20-spline) dan hujung output (berkunci, berspline, berflen) pada driveline dan implementasi anda.
Persekitaran kerja Habuk, lumpur, semburan garam atau kesejukan yang melampau mungkin memerlukan pengedap berkadar IP66, minyak sintetik suhu rendah atau kemasan anti-karat — nyatakan pada sebut harga.

Aplikasi Lazim & Tugas Penghantaran Kuasa

The EP-QZ-WRXL is engineered for silage disc mower / forage harvester. The scenarios below describe the specific power-transmission tasks the gearbox is designed to handle, with details of mounting position, drive path, and the technical demand on the gear and bearing set.

Disc Silage Mower (Front or Rear)

Drives the cutter disc bar. Mowing forage at high speeds with short stubble requires precise blade-tip speed and good cooling.

Forage Harvester Header Drive

Drives the cutting drum or row-crop header on a self-propelled forage harvester.

Mower-Conditioner Drive

Combined mower-conditioner units use the EP-QZ-WRXL to drive both the disc bar and the conditioning rolls in a packaged drive line.

Panduan Pemasangan & Pentauliahan

Correct installation of the silage gearbox is the single biggest factor in achieving the design service life. Follow the steps below, in order. Skipping or compressing any step usually shows up as oil leak, premature bearing failure, or noise within the first season.

  1. Persediaan keselamatan. Matikan enjin traktor, keluarkan kunci, lepaskan PTO, tetapkan brek parkir dan sekat roda. Pakai sarung tangan keselamatan dan pelindung mata. Pastikan alat berada pada sokongan yang stabil sebelum sebarang kerja sistem pacuan berfungsi.
  2. Sahkan kotak gear sebelum memasangnya. Check that the EP-QZ-WRXL model number, input flange dimensions, and input/output shaft specifications match both your tractor PTO and the implement input shaft. Mismatched flange or spline patterns will not be corrected by force-fitting.
  3. Isikan dengan pelincir. Sebelum penggunaan pertama, isi dengan pelincir yang dinyatakan — biasanya SAE 90 GL-4 — ke tengah tetingkap paras minyak. Rujuk jadual spesifikasi untuk kapasiti minyak yang tepat untuk unit anda; pengisian yang kurang menyebabkan haus awal galas, pengisian yang berlebihan meningkatkan suhu minyak dan memberi tekanan kepada pengedap.
  4. Pasang dan torkkan bolt. Bolt the gearbox flange to the implement using the OEM bolt set. Tighten in a diagonal pattern in three passes to the final torque (~ 110 N·m for M14 grade 8.8). Even loading prevents flange distortion and seal leak paths.
  5. Sambungkan aci PTO input. Pasangkan kuk aci pemacu PTO pada aci input kotak gear. Pastikan pin pengunci atau kolar tekan-tarik terpasang sepenuhnya. Pasangkan semula perisai keselamatan dengan kedua-dua rantai penahan disangkutkan pada traktor dan alat, jangan sekali-kali berputar dengan aci.
  6. Sambungkan aci keluaran. Luncurkan aci output ke dalam aci kerja alat, jajarkan kunci atau spline dan kunci dengan nat penahan dan pencuci yang dibekalkan. Sahkan apungan hujung aci berada dalam toleransi pengeluar — biasanya 0.05 mm hingga 0.20 mm.
  7. Periksa penjajaran aci. Dengan kotak gear dibolt dan aci disambungkan, putar perlahan-lahan dengan tangan. Jumlah larian keluar (TIR) ​​pada input dan output tidak boleh melebihi 0.10 mm. Sebarang tempat yang ketat atau calar yang boleh didengar menunjukkan isu penjajaran yang mesti dibetulkan sebelum operasi kuasa.
  8. Ujian tanpa beban dijalankan. Hidupkan PTO pada RPM enjin rendah (melahu hingga 540 RPM) selama lima hingga sepuluh minit. Dengar bunyi yang luar biasa, perhatikan resapan minyak dan periksa suhu perumah dengan tangan — ia sepatutnya suam apabila disentuh tetapi tidak cukup panas sehingga tidak selesa.
  9. Larian masuk di bawah beban separa. Untuk 50 jam pertama tugas, elakkan beban penuh. Ubah kelajuan dan beban secara perlahan-lahan untuk meletakkan gigi dan galas gear. Selepas tempoh penggunaan, toskan pelincir — ia akan mengandungi zarah pemecah masuk mikroskopik — dan isi semula dengan minyak baharu gred yang sama.
  10. Tetapkan jadual penyelenggaraan. Periksa paras minyak setiap 200 jam operasi atau setiap minggu semasa penggunaan berat. Toskan dan gantikan minyak gear setiap 500 jam atau sekali setiap musim, yang mana lebih awal. Lap bahagian luar perumah selepas setiap syif untuk mengelakkan pengumpulan kotoran yang memerangkap kelembapan pada pengedap.
⚠️ Amaran keselamatan. Jangan melebihi kelajuan input yang dinilai. Jangan kendalikan dalam keadaan kering — walaupun berjalan sebentar tanpa minyak akan merosakkan gear dan galas. Jangan sekali-kali menservis atau memeriksa kotak gear semasa PTO sedang digunakan. Sentiasa pasang semula semua pelindung dan perisai sebelum menyambung semula operasi.

Soalan Lazim

Common questions from buyers evaluating the EP-QZ-WRXL for their fleet or implement build. If your situation is not covered, send us the details and we will respond within one working day.

What certifications do you hold and is your product suitable for Australian farms?
Production runs under an ISO 9001:2015 quality system. Gears are designed against ISO 6336 load-capacity calculations and DIN 3960/3961 accuracy classes. Units are CE-marked where required and reviewed against the Australian AS 4024 machinery safety framework. We have been exporting agricultural gearboxes to Australia for several years; the seal and lubricant specifications used on units bound for Queensland, NSW, Victoria, and Western Australia have been adjusted for the local dust, heat, and humidity profiles.
How long is the lead time for a stock order vs. a custom build?
Stock catalogue items typically ship within 7–15 working days after order confirmation, subject to current inventory. A custom build requires drawing review, sample (if required), and serial production — usually 30–45 days for a first batch and 20–30 days for repeat batches. Sea-freight is normal for full-container quantities; air-freight is available for urgent partial shipments at additional cost.
What lubricant should I use, and how often should it be changed?
Use a quality GL-5 (or GL-4 minimum) gear oil — SAE 80W-90 covers most field temperatures. For very cold climates, switch to a synthetic 75W-90. First oil change is recommended at the end of the 50-hour run-in period; thereafter every 500 operating hours or once a season, whichever comes first. Always check the level weekly during peak season; running low even briefly damages the gear set.
Is the housing aluminum or cast iron — and which is better?
Both are offered. Cast iron (HT250 / QT500) has higher strength and absorbs shock better — it is the right choice for continuous heavy duty such as feed mixers, big balers, and heavy tilling. Aluminum (A356-T6 or ADC12) is lighter and dissipates heat more rapidly — better for small implements that get moved frequently or where weight reduction is valuable. The EP-QZ-WRXL is available in cast iron only for this application.
Can I replace the gearbox seals or bearings in the field?
Yes. The gearbox is built around standard bearing sizes and standardized seal kits. With a basic set of farm tools and a press (a simple bottle jack works for most cases), a competent farm mechanic can change a worn output seal or output bearing in two to three hours. We supply seal kits and bearing sets as separate spare-part SKUs — request the part list for the EP-QZ-WRXL and we will send pricing and lead time.
