⭐ Características clave y ventajas de ingeniería

🔒

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.

📚 Guía de selección de cajas de cambios

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.
📌 Standard Catalog vs Custom Specification
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.
📌 Compatibilidad con el tipo de eje de salida
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.
📌 Consideraciones sobre el peso y el montaje
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.
📌 Adaptación de la relación de engranajes a la velocidad de la punta de la cuchilla
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.

🛠 Guía de instalación y configuración

  1. Use Nord-Lock washers or thread-locking compound on all mounting bolts to prevent vibration-induced loosening during operation.
  2. Haga funcionar la caja de cambios sin carga durante 5-10 minutos, luego apáguela y vuelva a comprobar el nivel de aceite; los sellos y cojinetes nuevos suelen absorber una pequeña cantidad de aceite inicial.
  3. Limpie a fondo la superficie de montaje del implemento, eliminando todo el óxido, los restos de juntas viejas, las escamas de pintura y los residuos que puedan impedir un contacto perfecto con la brida de la caja de engranajes.
  4. Coloque la caja de cambios sobre los espárragos de montaje o los orificios para los pernos, verificando que el eje de entrada esté orientado hacia la toma de fuerza del tractor y que el eje de salida esté alineado con el cubo de la cuchilla o el rotor.
  5. Asegúrese de que el eje de la toma de fuerza tenga una superposición de estrías de al menos 50% en todas las posiciones de funcionamiento. Una superposición insuficiente provoca un desgaste rápido de las estrías y una posible separación del eje.
  6. Anote la fecha de instalación, la lectura del contador de horas del tractor y el número de serie de la caja de cambios en su registro de mantenimiento para el seguimiento de la garantía y los intervalos de servicio.
  7. Si va a reemplazar una unidad existente, drene completamente el aceite viejo, retire los sujetadores de montaje y baje con cuidado la caja de engranajes vieja. Fotografie la posición y anote las arandelas de ajuste utilizadas.

❓ Preguntas frecuentes

❓ 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.
