⭐ Ciri-ciri Utama & Kelebihan Kejuruteraan

⚗

Dual-Lip NBR Oil Seals

Twin-lip nitrile seals with integrated dust excluder on every shaft exit, rated to IP65, preventing moisture and crop debris from entering the gear chamber.

🔒

Optimized Lightweight Geometry

Finite-element-optimized casing walls remove unnecessary material while maintaining full load capacity, reducing installed weight by 15% versus previous-generation housings.

⚡

20CrMnTi Forged Gear Blanks

All gear blanks are closed-die forged (not cast) to align grain flow with tooth roots, increasing bending fatigue strength by 30% over alternative casting methods.

🔄

97%+ Mechanical Efficiency Rating

Super-finished gear flanks (Ra â‰Ī 0.6 Ξm) and optimized tooth contact deliver over 97% efficiency, reducing fuel consumption and allowing cooler continuous operation.

🔨

Premium Tapered Roller Bearings

All positions fitted with Japanese-standard tapered roller bearings rated for 5,000+ hours L10 life, handling combined radial and thrust loads simultaneously.

🌡

GGG-50 Spheroidal Iron Casing

EN-GJS-500-7 housing tested to 25 bar hydrostatic pressure, providing extreme fatigue strength for applications exceeding 100 HP continuous input power.

🔧 Keserasian & Rujukan Silang Peralatan

🔄 Cross-Reference Compatibility for EP-55

The EP-55 is engineered as a direct replacement or upgrade for gearboxes fitted to equipment from leading manufacturers including:

New Holland • Bush Hog • Kioti • Vicon • Bomford • Valtra • Yanmar • Lovol

Penafian: Nama jenama di atas dirujuk semata-mata untuk pengenalpastian keserasian. Ever-power Australia Mower Gearbox Co.,Ltd. tidak bergabung dengan, disokong oleh atau dibenarkan oleh mana-mana pengeluar tersenarai. Semua tanda dagangan adalah milik pemilik masing-masing.

📚 Panduan Pemilihan Kotak Gear

Proper gearbox selection protects your investment and maximizes field productivity. Here is how to determine if the EP-55 is right for your operation:

📌 Pilihan PTO 540 RPM vs 1000 RPM
The EP-55 operates at 540 rpm. Most rotary mowers use 540 RPM PTO. The 1000 RPM standard is for larger implements on high-HP tractors. Never connect a 540 RPM gearbox to a 1000 RPM PTO — the doubled speed will destroy bearings and gears within minutes.
📌 Perumah Besi Tuang vs Perumah Aluminium
The EP-55 uses a grey cast iron housing. Cast iron excels in vibration damping, impact resistance, and heat dissipation — ideal for rough, rocky mowing conditions. Aluminium is lighter and more corrosion-resistant, better suited to wet environments and weight-sensitive implements.
📌 Katalog Standard vs Spesifikasi Tersuai
The EP-55 is available as a standard catalog item shipping in 3-5 days. If your application requires a non-standard ratio, shaft type, or mounting configuration, our engineering team offers custom designs with 4-6 week lead times. Minimum order quantities may apply.
📌 Keserasian Jenis Aci Output
The EP-55 features 1 3/8 Z6, Cone base aequilate spline shaft output. Verify your blade hub or implement rotor accepts this shaft type before ordering. We offer multiple output configurations — spline, taper, keyway, and flange — to match virtually any existing installation.
📌 Pertimbangan Berat dan Pemasangan
At 28.7 Kg, the EP-55 is designed for mid-size utility tractor attachments. Confirm your implement frame and three-point hitch can support this weight plus the weight of the blade assembly. Mounting bolt pattern and orientation should match your existing layout.

🛠 Panduan Pemasangan & Persediaan

  1. Tanggalkan aci PTO traktor dan sokong alat pemotong rumput dengan selamat pada penyangga atau blok bicu sebelum memulakan prosedur pemasangan kotak gear.
  2. Bagi unit yang beratnya melebihi 25 kg, gunakan pengangkat rantai, kren enjin atau pengangkat dua orang untuk meletakkan kotak gear. Jangan sekali-kali cuba mengangkat kotak gear berat secara bersendirian.
  3. Isi kotak gear dengan minyak gear yang disyorkan (SAE 80W-90 atau 85W-140 EP) sehingga paras yang ditunjukkan pada kaca penglihatan atau batang celup. Jangan isi secara berlebihan.
  4. Sebelum beroperasi pada beban penuh, jalankan urutan pecutan masuk secara berperingkat: 30 minit pada separuh pendikit, kemudian 30 minit pada pendikit tiga suku, sebelum menggunakan kelajuan PTO penuh.
  5. Inspect the implement mounting pad for flatness using a straightedge. Any warping exceeding 0.5 mm should be corrected before the new gearbox is installed.
  6. Use Nord-Lock washers or thread-locking compound on all mounting bolts to prevent vibration-induced loosening during operation.
  7. Run the gearbox at no load for 5-10 minutes, then shut down and re-check oil level — new seals and bearings often absorb a small amount of initial oil.

❓ Soalan Lazim

❓ Can this unit directly replace my OEM gearbox?

Yes. Our mounting patterns, shaft diameters, and spline profiles match industry-standard OEM dimensions. We supply detailed technical drawings for cross-referencing. If your existing unit differs slightly, our engineering team can advise on adapters.

❓ What happens if I accidentally run it dry?

Stop the PTO immediately. Even a few minutes without oil causes severe gear scoring and bearing damage, typically requiring a full internal rebuild. Always verify oil level before engaging the PTO.

❓ How should I store the gearbox off-season?

Run briefly to warm the oil, then top up to the full mark. Apply grease to exposed shaft surfaces and seal any open ports. Store in a dry, covered area. Before next season, verify oil level and rotate input by hand to check free movement.

❓ Bolehkah saya menggantikan set gear sahaja?

Ya. Set gear gantian tersedia untuk semua model dan menjimatkan kos apabila perumah, galas dan aci kekal dalam keadaan baik. Kami mengesyorkan penggantian galas dan pengedap secara serentak untuk hasil terbaik.

❓ Bolehkah kotak gear ini mengendalikan putaran PTO terbalik?

Reka bentuk serong lingkaran kami beroperasi dengan betul dalam kedua-dua arah putaran tanpa pengubahsuaian. Walau bagaimanapun, semak keperluan alat khusus anda, kerana sesetengah pemasangan bilah pemotong rumput sensitif arah.
