TNT-2 Gearbox
Designed for applications where the irrigation system may need to be towed
This gearbox is the perfect solution for a towable irrigation system. Growers typically prefer this gearbox over a gearbox with a towable hub. Simply disengage the worm and tow your system to its working location, then re-engage the worm and you are ready to run. The CX coupler is the perfect compliment for the TNT-2 gearbox due to the ability to control coupler disengagement at the gearbox.
The UMC patented TNT-2 final drive gearbox is designed specifically for applications where a center CHINAMFG or lateral move/ linear irrigation system needs to be towed. The gearbox provides the ability to disengage the worm gear and allows users to move systems from 1 area to another without requiring a Towable Hub add on.

كيفية تركيب ومحاذاة مخفض السرعة الدودي بشكل صحيح
يُعدّ تركيب ومحاذاة مُخفّض سرعة الدودة بشكل صحيح أمرًا بالغ الأهمية لضمان الأداء الأمثل وطول العمر. اتبع الخطوات التالية لتركيب ومحاذاة مُخفّض سرعة الدودة:
- تحضير: اجمع جميع الأدوات والمعدات ومستلزمات السلامة اللازمة قبل البدء بعملية التركيب.
- تحديد الموقع: ضع مخفض سرعة الدودة في المكان المطلوب، مع التأكد من تثبيته بإحكام على سطح ثابت. استخدم أدوات التثبيت المناسبة وأقواس التثبيت حسب الحاجة.
- محاذاة العمود: تحقق من محاذاة عمودَي الإدخال والإخراج. استخدم أدوات قياس دقيقة للتأكد من أن العمودين متوازيان ومتوازيان مع بعضهما البعض.
- محاذاة اللوحة الأساسية: قم بمحاذاة قاعدة المخفض مع الأساس أو سطح التركيب. تأكد من أن القاعدة مستوية ومحاذية بشكل صحيح قبل تثبيتها في مكانها.
- شد البراغي: Gradually and evenly tighten the mounting bolts to the manufacturer’s specifications. This helps ensure proper contact between the reducer and the mounting surface.
- التحقق من التخليص الجمركي: تأكد من وجود مساحة كافية لأي مكونات أو أجزاء دوارة قد تتحرك أثناء التشغيل. تجنب أي تداخل قد يتسبب في تلف أو مشاكل في الأداء.
- تشحيم: Apply the recommended lubricant to the worm reducer according to the manufacturer’s guidelines. Proper lubrication is essential for smooth operation and reducing friction.
- اختبار المحاذاة: بعد التركيب، قم بتشغيل مخفض السرعة الدودي لفترة وجيزة بدون حمل للتحقق من وجود أي ضوضاء أو اهتزازات غير عادية أو مشاكل في المحاذاة.
- اختبار التحميل: قم بتطبيق الحمل المطلوب تدريجياً على مخفض السرعة الدودي وراقب أدائه. تأكد من أن المخفض يعمل بسلاسة وكفاءة في ظل ظروف الحمل.
It’s important to refer to the manufacturer’s installation guidelines and specifications for your specific worm reducer model. Proper installation and alignment will contribute to the gearbox’s reliability, efficiency, and overall functionality.
How to Calculate the Input and Output Speeds of a Worm Gearbox?
Calculating the input and output speeds of a worm gearbox involves understanding the gear ratio and the principles of gear reduction. Here’s how you can calculate these speeds:
- سرعة الإدخال: The input speed (N1) is the speed of the driving gear, which is the worm gear in this case. It is usually provided by the manufacturer or can be measured directly.
- سرعة الإخراج: The output speed (N2) is the speed of the driven gear, which is the worm wheel. To calculate the output speed, use the formula:
N2 = N1 / (Z1 * i)
Where:
N2 = Output speed (rpm)
N1 = Input speed (rpm)
Z1 = Number of teeth on the worm gear
i = Gear ratio (ratio of the number of teeth on the worm gear to the number of threads on the worm)
It’s important to note that worm gearboxes are designed for gear reduction, which means that the output speed is lower than the input speed. Additionally, the efficiency of the gearbox, friction, and other factors can affect the actual output speed. Calculating the input and output speeds is crucial for understanding the performance and capabilities of the worm gearbox in a specific application.
مزايا استخدام مخفض السرعة الدودي في الأنظمة الميكانيكية
توفر مخفضات السرعة الدودية العديد من المزايا التي تجعلها مناسبة لمختلف الأنظمة الميكانيكية:
- نسبة تخفيض التروس العالية: توفر علب التروس الدودية تخفيضًا كبيرًا في السرعة، مما يجعلها مثالية للتطبيقات التي تتطلب نسبة تخفيض عالية للتروس دون الحاجة إلى تروس متعددة.
- تصميم صغير الحجم: تتميز مخفضات السرعة الدودية بتصميم صغير الحجم وموفر للمساحة، مما يسمح باستخدامها في التطبيقات ذات المساحة المحدودة.
- قفل ذاتي: تتميز علب التروس الدودية بخاصية القفل الذاتي، مما يعني أن لولب الدودة يمنع عجلة الدودة من عكس حركتها. وهذا مفيد للتطبيقات التي تتطلب من علبة التروس تثبيت حمولة في مكانها دون الحاجة إلى آليات كبح خارجية.
- تشغيل سلس وهادئ: تعمل علب التروس الدودية بحركة انزلاقية بين الأسنان، مما ينتج عنه تشغيل أكثر سلاسة وهدوءًا مقارنة ببعض أنواع علب التروس الأخرى.
- ناقل حركة عالي العزم: يمكن لصناديق التروس الدودية نقل مستويات عزم دوران عالية، مما يجعلها مناسبة للتطبيقات التي تتطلب خرج عزم دوران قوي.
- تبديد الحرارة: تساهم حركة الانزلاق بين البرغي الدودي وعجلة الدودة في تبديد الحرارة، وهو ما يمكن أن يكون مفيدًا في التطبيقات التي تولد الحرارة أثناء التشغيل.
- أداء مستقر: توفر مخفضات السرعة الدودية أداءً مستقرًا وموثوقًا، مما يجعلها مناسبة للتشغيل المستمر في مختلف الأنظمة الصناعية والميكانيكية.
Despite these advantages, it’s important to note that worm gearboxes also have limitations, such as lower efficiency compared to other gear types due to the sliding motion and potential for higher heat generation. Therefore, selecting the appropriate type of gearbox depends on the specific requirements and constraints of the application.
