Engineering Features of the Rake Gearbox

Each of the cards below describes a specific, measurable attribute of the EP-DX300-2 unit. Generic claims have been kept out — every number here is tied to a manufacturing process or a verified test result.

️ 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 medium 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.
Australian Climate Ready
Selected seal and oil specifications resist UV-driven embrittlement and the dusty operating profile typical of Queensland and NSW broadacre conditions.
Inspection Documented
Each shipment includes an in-house inspection sheet logging gear-tooth contact pattern, backlash, bearing torque, and run-in noise reading — full traceability per unit.
⚙️ Hardened Gear Set
Gear teeth are forged from 20CrMnTi alloy steel, then carburized and oil-quenched to a surface hardness of HRC 58–62 with a tough HRC 33–45 core. Load capacity is more than double that of basic 45# steel gears.

How to Select the Right Rake Gearbox

Use the three-step approach below to match a EP-DX300-2-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-DX300-2. 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

Aplikasi Lazim & Tugas Penghantaran Kuasa

The EP-DX300-2 is engineered for rotary / side-delivery rake. 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.

Rotary Rake

Drives the rake rotor that gathers cut hay into windrows. Smooth drive at moderate speed is key.

Side-Delivery Rake

Drives the rake reel that side-delivers hay into rows. Compact gearbox with reliable seal package needed.

Powered Harrow Drive

For tine harrows that share the rake gearbox housing format. High torque at low rotor speed.

Panduan Pemasangan & Pentauliahan

Correct installation of the rake 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-DX300-2 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. Before first use, fill with the specified lubricant — typically SAE 75W-90 synthetic GL-5 — to the centre of the oil-level window. Refer to the spec table for the exact oil capacity for your unit; underfilling causes early bearing wear, overfilling raises oil temperature and stresses seals.
  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-DX300-2 for their fleet or implement build. If your situation is not covered, send us the details and we will respond within one working day.

Bagaimanakah saya memilih nisbah gear yang betul untuk traktor dan peralatan saya?
Match the ratio to the rotor or output speed your implement is designed for. As a rule of thumb, divide your tractor PTO speed (540 or 1000 RPM) by the implement’s required input speed — that gives you the target reduction or step-up. For a rotary / side-delivery rake, ratios in the 1:1 – 1:2 range are most common. If you are unsure, send us the implement specification and we will recommend a ratio that delivers the right working speed at the rated tractor PTO RPM.
Bilakah saya perlu menentukan input 540 RPM berbanding input 1000 RPM?
540 RPM is standard for tractors below approximately 100 HP and remains the most common interface in farm fleets. 1000 RPM is preferred on larger tractors (100+ HP) and where the implement requires higher output shaft speed for the same gear ratio. Always confirm what your tractor’s PTO actually delivers before specifying — the gearbox must match the input source. The EP-DX300-2 is available with both input options.
Adakah anda menawarkan kotak gear spesifikasi OEM dan tersuai? Apakah minimumnya?
Ya. Kami secara rutin membina mengikut lukisan OEM dan spesifikasi tersuai termasuk nisbah bukan standard, hujung aci khas, bahan perumah alternatif, corak bebibir tersuai dan pakej pengedap yang disesuaikan. MOQ standard untuk model katalog ialah satu karton (biasanya 5 hingga 50 unit bergantung pada saiz). Untuk binaan tersuai penuh, MOQ biasanya 50 unit, dengan artikel pertama diluluskan terhadap lukisan atau sampel sebelum pengeluaran bersiri bermula.
What is your warranty policy and how do I make a claim?
The standard warranty is 12 months from the shipment date covering manufacturing defects in materials and workmanship under normal use. Extended 18-month or 24-month coverage is available for OEM contracts. For a claim, send a short video or photo showing the defect, the unit serial number, and a description of the operating context. We will respond within 24 hours and, if the claim is valid, supply a replacement or replacement parts free of charge.
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.
