⭐ 主な特長とエンジニアリング上の利点

🔒

Stainless Steel Breather Valve

Labyrinthed breather prevents pressure build-up during temperature swings while blocking water and dust ingress — a common failure point in cheaper gearboxes.

⚡

CNC-Bored Bearing Seats, IT6 Tolerance

All bearing bores finish-bored to ISO IT6 on CNC horizontal boring mills, ensuring perfect bearing fit and eliminating the fretting corrosion caused by loose seats.

🔄

Laser-Etched Traceability Code

Every housing is laser-marked with a unique serial number linking to full material, heat-treatment, and inspection records for complete supply-chain traceability.

🔨

Balanced Gear Set Assembly

Complete gear sets are dynamically balanced as a matched pair to ISO G6.3, reducing transmitted vibration to the mower frame and extending component fatigue life.

🌡

Integrated Overload Shear Hub

Built-in shear bolt hub on the output protects the entire gear train from catastrophic damage when blades strike immovable objects like buried concrete or steel.

🛠

Thermo-Compensating Bearing Spacer

Calibrated aluminium spacer between bearing sets expands proportionally with temperature, maintaining optimal preload from cold start through peak operating temperature.

📚 ギアボックス選定ガイド

Getting gearbox selection right the first time saves money and headaches. Here is a systematic approach to specifying the EP-MDH-65:

📌 Cast Iron Housing vs Aluminium Housing
The EP-MDH-65 uses a aluminium alloy or 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.
📌 標準カタログ vs カスタム仕様
The EP-MDH-65 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.
📌出力軸タイプの互換性
The EP-MDH-65 features Flange mount hub 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.
📌重量と取り付けに関する考慮事項
At 22 Kg (approx.), the EP-MDH-65 is designed for disc mower cutter bars. 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.
📌 ギア比とブレード先端速度のマッチング
For the EP-MDH-65 with ratio(s) N/A (Hub Drive), calculate your required blade tip speed: typically 4,500-5,500 m/min for standard rotary cutters, 3,000-4,000 m/min for heavy brush cutting, and 5,500-6,500 m/min for fine finish mowing. Output RPM = PTO RPM ÷ ratio. Multiply by blade diameter to get tip speed.

🛠 インストールとセットアップガイド

  1. 運転中の振動による緩みを防ぐため、すべての取り付けボルトにNord-Lockワッシャーまたはねじロック剤を使用してください。
  2. ギアボックスを無負荷状態で5～10分間運転した後、停止させてオイルレベルを再確認してください。新しいシールやベアリングは、初期段階で少量のオイルを吸収することがよくあります。
  3. 作業機の取り付け面を徹底的に清掃し、錆、古いガスケット材、塗料の剥がれ、およびギアボックスフランジとの密着を妨げる可能性のある破片をすべて取り除きます。
  4. ギアボックスをマウントスタッドまたはボルト穴に配置し、入力シャフトがトラクターのPTOに面し、出力シャフトがブレードハブまたはローターと一直線になっていることを確認します。
  5. PTOシャフトは、すべての動作位置において、少なくとも50%のスプライン重なりを確保してください。重なりが不十分な場合、スプラインの摩耗が急速に進み、シャフトが分離する可能性があります。
  6. Record the installation date, tractor hour meter reading, and gearbox serial number in your maintenance log for warranty and service interval tracking.
  7. If replacing an existing unit, drain the old oil completely, remove mounting fasteners, and carefully lower the old gearbox. Photograph the orientation and note any shim washers used.

❓よくある質問

❓ What quality inspections do you perform?

Every gearbox undergoes 100% dimensional inspection (CMM), gear tooth geometry verification (Gleason analyzer), hardness testing, oil-leak testing, and no-load run-in testing before shipment.

❓ What warranty do you provide?

Every gearbox ships with a 12-month warranty covering material and workmanship defects under normal operating conditions. Warranty claims are handled through our dealer network with replacement units dispatched within 48 hours of approval.

❓ How do I determine the correct model for my mower?

You need four pieces of information: (1) tractor PTO HP, (2) PTO speed (540 or 1000 RPM), (3) current gearbox mounting dimensions, and (4) output shaft type. Send us these details and we will cross-reference the best match.

❓ Is synthetic gear oil recommended?

Synthetic PAO-based 75W-90 or 80W-140 GL-5 oil is excellent, especially in extreme temperatures. Synthetics offer better cold-flow, higher film strength, and longer drain intervals. Fully compatible with all our seal materials.

❓ What shipping methods are available?

Sea freight (20-35 days), air freight (5-10 days), and express courier (3-5 days) worldwide. Sea freight is most economical for bulk orders. All shipments include protective packaging, documentation, and full tracking.
