علبة تروس PTO لآلة جمع التبن

تستخدم تروسنا فولاذًا من سبائك 20CrMnTi مع التصليد السطحي لضمان صلابة سطحية تتراوح بين 58-62 HRC مع الحفاظ على قلب صلب ومرن - وهو أفضل بكثير من تروس الفولاذ الطري الموجودة في المنتجات الرديئة.

يوفر غلاف علبة التروس المحكم الإغلاق حمايةً بمعيار IP65 ضد الغبار ورذاذ الماء، مما يجعله مثالياً لظروف المناطق النائية القاسية في أستراليا. أما البدائل الرخيصة فغالباً ما تفتقر إلى الإحكام المناسب وتتعطل في البيئات المتربة.

تحقق ملامح أسنان التروس المحسّنة بواسطة الكمبيوتر كفاءة نقل الطاقة أعلى من 96%، مما يقلل من استهلاك الوقود وتوليد الحرارة مقارنة بالبدائل المصممة بشكل سيئ والتي تهدر 10-15% من طاقة الإدخال على شكل حرارة.

على الرغم من أن تكلفتنا الأولية أعلى بمقدار 15-25% من خيارات الميزانية، إلا أن عمر الخدمة الممتد (أكثر من 10000 ساعة مقابل 3000 ساعة نموذجية) ومتطلبات الصيانة المنخفضة توفر ما بين 40-60% من المدخرات على مدار دورة حياة المعدات.

توفر المعالجة السطحية متعددة الطبقات، بما في ذلك طبقة أساسية من فوسفات الزنك وطبقة علوية من الإيبوكسي، مقاومة ممتازة للتآكل في البيئات الساحلية الرطبة، والتعرض لرذاذ الملح، والتلامس الكيميائي من الأسمدة.

تتيح منصة علبة التروس المعيارية الخاصة بنا إمكانية استبدال مجموعات التروس في الموقع لتكوينات نسب مختلفة، مما يقلل من تكاليف المخزون للتجار ويتيح التكيف السريع مع الأدوات المختلفة.

Unpack the PTO gearbox and cross-reference the nameplate data with your order specifications. Confirm the gear ratio, input/output shaft dimensions, and rotation direction are correct for your hayrake.

Prepare the hayrake mounting interface by removing the old gearbox (if replacing) and cleaning all mating surfaces. Inspect mounting holes for thread damage or elongation.

Apply a thin film of anti-seize compound to the mounting bolt threads and the gearbox-to-frame mating surface. This prevents corrosion-bonding and facilitates future maintenance.

Lift the gearbox into position using appropriate lifting equipment (typical weight 25-80 kg depending on model). Never attempt to manually handle heavy gearbox units.

Insert and hand-tighten all mounting fasteners in a star pattern. Then torque to specification in two passes: first to 60% of final torque, then to 100%. Typical values: M10 = 50 Nm, M12 = 85 Nm, M16 = 210 Nm.

Attach the PTO drive shaft to the input spline. The shaft should slide freely onto the spline with no binding. If resistance is felt, check for burrs, misalignment, or incorrect spline count.

Connect the gearbox output to the hayrake’s working element. Verify rotational alignment using a dial indicator if precision coupling is required. Maximum allowable angular misalignment: 1°.

Add the specified lubricant type and quantity. For most models, fill to the centre line of the sight glass with the gearbox in its normal operating position.

Reinstall all PTO shaft guards, gearbox covers, and safety decals. Ensure 360° coverage of all rotating components within operator reach.

Commission the gearbox by running at no-load for 15 minutes, then gradually introducing load over 2 hours. Record baseline temperature and vibration readings for future comparison.

Purpose: Equipping a new hayrake with a high-performance pto gearbox.

Customer Review: “We ordered five units for our fleet. Every one was perfectly packed, correctly specified, and delivered on time. Our mechanics were impressed with the build quality. Will order again.” — Michael O’Brien, Geraldton, WA

Purpose: Emergency replacement of a seized hayrake gearbox during peak season.

Customer Review: “Our previous gearbox overheated constantly. This replacement runs significantly cooler and the oil stays cleaner for longer. The sealing is clearly a step above the competition.” — Chris Lawson, Esperance, WA

Purpose: Sourcing a cost-effective replacement for an imported hayrake gearbox.

Customer Review: “After trying two cheaper alternatives that both failed within aseason, we switched to this gearbox. It has now run over 1,500 hours without any issues. Quality is outstanding.” — Craig Montrose, Kalgoorlie, WA

Purpose: Replacing a failed oem gearbox on a 10-year-old hayrake.

Customer Review: “The gearbox arrived ahead of schedule and was a perfect bolt-on fit. We had zero downtime during our busiest period. Highly recommend for any hayrake operator.” — Alan Davenport, Albany, WA

Purpose: Bulk purchase of hayrake gearboxes for a machinery dealer network.

Customer Review: “The price-to-quality ratio is exceptional. We compared with European OEM parts costing 3x more and found no difference in performance after 800+ hours of operation.” — Tony Marlborough, Bunbury, WA

The correct gear ratio depends on your tractor’s PTO speed (540 or 1000 RPM) and the required implement speed. For most hayrake applications, ratios between 1.47:1 and 1:1.9 are common. Our engineering team can calculate the optimal ratio based on your specific tractor and hayrake model. Contact us with your specifications for a free recommendation.

Yes, our PTO gearboxes are designed as direct replacements for major brand hayrake gearboxes. We offer matching mounting patterns, spline configurations, and gear ratios for popular models from brands like John Deere, Case IH, New Holland, and others. Provide us with your current gearbox part number or machine model for exact cross-reference compatibility.

Standard gearbox models ship within 5-7 business days from our warehouse. Custom-built gearboxes with non-standard ratios, shaft configurations, or special materials typically require 15-25 business days. We maintain extensive stock of common agricultural gearbox models for fast turnaround on urgent orders.

We recommend the first oil change at 50 hours (break-in period) to flush out metal particles from initial gear seating. Subsequent oil changes should occur every 500 hours or annually, whichever comes first. In severe-duty conditions (high temperature, dusty environments, continuous operation), reduce the interval to 250 hours. Always use the specified gear oil grade.

Yes, we offer tiered pricing for bulk orders. MOQ starts at just 1 unit for standard models, but volume discounts begin at 5 units (5-8% off), 20 units (10-15% off), and 50+ units (negotiable project pricing). OEM customers and distributors receive additional programme benefits. Request a quote for your specific volume.

All our agricultural PTO gearboxes carry a standard 18-month warranty from date of delivery, covering defects in materials and workmanship. Extended warranty options (24 or 36 months) are available for registered units. The warranty includes free replacement parts and technical support. Normal wear items (seals, lubricant) and damage from misuse or improper installation are excluded.

Absolutely. Our hayrake PTO gearbox is designed with generous safety factors (typically 2.0-2.5x rated load) to absorb the shock loads and transient peaks common in hayrake applications. The hardened gear teeth, oversized bearings, and robust housing all contribute to excellent shock load resilience. For extreme applications, we offer reinforced models with even higher ratings.

We offer models for both 540 RPM and 1000 RPM PTO systems, as well as dual-speed models that accept either input. When ordering, specify your tractor’s PTO speed so we can supply the correct gear ratio for your target output speed. Adapters for converting between 6-spline (540 RPM) and 21-spline (1000 RPM) shafts are also available.

Yes, we ship nationwide across Australia including remote and regional areas. We use established freight networks experienced in heavy agricultural equipment delivery. Standard delivery to major cities is 3-5 business days; regional areas 5-10 business days. Express freight options are available for urgent requirements.

Yes, we manufacture both PTO gearboxes and PTO shafts, so we can supply a complete, matched drivetrain assembly. This ensures optimal compatibility, correct shaft length, proper U-joint phasing, and simplified ordering. Bundled packages offer cost savings of 8-12% compared to purchasing components separately.
