⭐ ویژگی‌های کلیدی و مزایای مهندسی

🔨

آب‌بندی شفت سه مرحله‌ای

لابیرنت داخلی + آب‌بند دو لبه FKM + حلقه V شکل خارجی، یک سد دفاعی سه‌گانه در برابر نفوذ آب، گل و لای و گرد و غبار ریز به حفره‌های یاتاقان تشکیل می‌دهند.

🌡

پره‌های خنک‌کننده خارجی یکپارچه

سطح اضافی 35% ناشی از شیارهای خنک‌کننده ماشینکاری شده، دفع گرما را تسریع می‌کند و دمای روغن را در طول چمن‌زنی تابستانی با بار کامل و مداوم، زیر 80 درجه سانتیگراد نگه می‌دارد.

🛠

18CrNiMo7-6 Aerospace Gear Steel

Vacuum-carburized gears from aircraft-grade alloy achieve HRC 60-63 surface and a tough pearlitic core, meeting AGMA Class 10 tooth accuracy standards.

🔬

98%+ Power Delivery Efficiency

Mirror-polished flanks (Ra ≤ 0.4 μm) and AGMA Class 11 accuracy virtually eliminate parasitic losses, ensuring every horsepower reaches the cutting blade.

⚖

4140 Chrome-Moly Output Flange

Forged steel output flange heat-treated to HRC 28-32, drilled for heavy-duty blade carriers up to 50 kg — eliminating the flex found in cast alternatives.

🚀

GGG-60 Heavy-Plate Housing

EN-GJS-600-3 ductile iron with 18 mm walls and FEA-optimized ribbing, engineered for sustained 150+ HP loads without measurable housing flex.

📚 راهنمای انتخاب گیربکس

Getting gearbox selection right the first time saves money and headaches. Here is a systematic approach to specifying the EP-RC81:

📌 Cast Iron Housing vs Aluminium Housing
The EP-RC81 uses a ductile 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-RC81 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.
📌 سازگاری نوع شفت خروجی
The EP-RC81 features 1 3/8 Z6, Taper spline 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.
📌 ملاحظات وزن و نصب
At 28.7 Kg, the EP-RC81 is designed for large-frame tractor implements and heavy-duty mowers. 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.
📌 تطبیق نسبت دنده با سرعت نوک تیغه
For the EP-RC81 with ratio(s) 1:1.93 / 1:1.46, 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.

🛠 راهنمای نصب و راه‌اندازی

  1. جعبه دنده را روی پایه‌های نصب یا سوراخ‌های پیچ قرار دهید و مطمئن شوید که شفت ورودی رو به محور انتقال قدرت تراکتور و شفت خروجی با توپی یا روتور تیغه هم‌تراز است.
  2. مطمئن شوید که شفت PTO در تمام موقعیت‌های کاری حداقل همپوشانی خار 50% داشته باشد. همپوشانی ناکافی باعث سایش سریع خار و احتمال جدا شدن شفت می‌شود.
  3. Record the installation date, tractor hour meter reading, and gearbox serial number in your maintenance log for warranty and service interval tracking.
  4. 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.
  5. Insert all mounting bolts finger-tight first, then torque to specification in a cross (star) pattern to ensure even clamping. Typical torque: 80-120 Nm depending on bolt size.
  6. With the implement raised and blades clear of the ground, engage the PTO at low idle speed. Listen for any unusual noise and observe for vibration or oil leaks.
  7. Verify that the mower implement safety chain or restraint is properly connected to prevent the gearbox from contacting the ground if the three-point hitch fails.

❓ سوالات متداول

❓ How do I select the right gear ratio?

Match the ratio to your blade tip speed target. Lower ratios (e.g. 1:1) give higher blade RPM for finish mowing; higher ratios (e.g. 1:1.93 or above) trade speed for torque, ideal for thick brush. Calculate: output RPM = input RPM ÷ ratio.

❓ What is the expected operational lifespan?

With proper maintenance, our gearboxes typically deliver 3,000 to 5,000 operating hours. Many units in the field have exceeded 6,000 hours. Lifespan depends on operating load, maintenance compliance, and field conditions.

❓ Is this suitable for mulching applications?

Yes. Our gearboxes are widely used on mulching mowers and brush cutters. For mulching, select a model rated 25-30% above your actual PTO horsepower to provide a safety margin against the intermittent shock loads typical of mulching.

❓ 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.

⭐ نظرات مشتریان و گزارش‌های میدانی

★★★★★

📍 South Australia, Australia

We maintain 40+ mowers for council contracts. Switching to this brand has reduced our gearbox failure rate by over 60 percent.

★★★★★

📍 قونیه، ترکیه

Running in extreme cold (-25 °C) winters and hot summers. Synthetic oil in this gearbox handles both extremes without issue.

★★★★★

📍 آیووا، ایالات متحده

We replaced three OEM gearboxes with this model across our fleet. Gear quality and seal performance are noticeably superior. Reordering for next season.

★★★★☆

📍 فیصل آباد، پاکستان

Third year of heavy use on our orchard floor management. Still going strong with just regular oil changes. The best aftermarket gearbox I have found.

★★★★☆

📍 پولتاوا، اوکراین

Good gearbox with a solid, hefty feel. Delivery to Ukraine was fast. Only needed a small spacer washer to fit our older mower model.
