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 UMC 760-UV Bronze final drive gearbox is our largest and most durable gearbox with an extended output shaft designed for the most extreme growing conditions. It features a high strength aluminum bronze bull gear and a heat treated steel worm gear giving it a much higher load capacity than the standard 760-UV. Additionally, this gear combination greatly reduces gear wear, extending the useful life of the gearbox. It also features a 2.5″ output shaft to accommodate more overhung load. It is designed for use on center pivots, corners, lateral move/ linear irrigation systems and carts where a 52:1 gear ratio and extended output shaft are standard specifications.
Features and Benefits
- 2.5″ output shaft
- 52:1 gear ratio with a 25° pressure angle
- Unique dual input and output seal design
- Bronze Gear
- Heat Treated Steel Worm Gear

Cara Memasang dan Menyelaraskan Reducer Cacing dengan Benar
Pemasangan dan penyelarasan reduktor ulir yang tepat sangat penting untuk memastikan kinerja optimal dan umur pakai yang panjang. Ikuti langkah-langkah berikut untuk memasang dan menyelaraskan reduktor ulir:
- Persiapan: Kumpulkan semua alat, perlengkapan, dan peralatan keselamatan yang diperlukan sebelum memulai proses pemasangan.
- Penempatan: Tempatkan reduktor cacing pada lokasi yang diinginkan, pastikan terpasang dengan aman pada permukaan yang stabil. Gunakan pengencang dan braket pemasangan yang sesuai jika diperlukan.
- Penyelarasan Poros: Periksa keselarasan poros input dan output. Gunakan alat ukur presisi untuk memastikan bahwa poros-poros tersebut sejajar dan lurus satu sama lain.
- Penyelarasan Pelat Dasar: Sejajarkan pelat dasar reduktor dengan fondasi atau permukaan pemasangan. Pastikan pelat dasar rata dan sejajar dengan benar sebelum mengencangkannya pada tempatnya.
- Pengencangan Baut: Gradually and evenly tighten the mounting bolts to the manufacturer’s specifications. This helps ensure proper contact between the reducer and the mounting surface.
- Periksa Izin: Pastikan terdapat ruang yang cukup untuk komponen atau bagian yang berputar yang mungkin bergerak selama pengoperasian. Hindari gangguan apa pun yang dapat menyebabkan kerusakan atau masalah kinerja.
- Pelumasan: Apply the recommended lubricant to the worm reducer according to the manufacturer’s guidelines. Proper lubrication is essential for smooth operation and reducing friction.
- Pengujian Keselarasan: Setelah pemasangan, jalankan reduktor cacing sebentar tanpa beban untuk memeriksa apakah ada suara aneh, getaran, atau masalah ketidaksejajaran.
- Pengujian Beban: Secara bertahap, berikan beban yang diinginkan pada reduktor cacing dan pantau kinerjanya. Pastikan reduktor beroperasi dengan lancar dan efisien dalam kondisi beban tersebut.
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.
Energy Efficiency of a Worm Gearbox: What to Expect
The energy efficiency of a worm gearbox is an important factor to consider when evaluating its performance. Here’s what you can expect in terms of energy efficiency:
- Typical Efficiency Range: Worm gearboxes are known for their compact size and high gear reduction capabilities, but they can exhibit lower energy efficiency compared to other types of gearboxes. The efficiency of a worm gearbox typically falls in the range of 50% to 90%, depending on various factors such as design, manufacturing quality, lubrication, and load conditions.
- Inherent Losses: Worm gearboxes inherently involve sliding contact between the worm and worm wheel. This sliding contact generates friction, leading to energy losses in the form of heat. The sliding action also contributes to lower efficiency when compared to gearboxes with rolling contact.
- Helical-Worm Design: Some manufacturers offer helical-worm gearbox designs that combine elements of helical and worm gearing. These designs aim to improve efficiency by incorporating helical gears in the reduction stage, which can lead to higher efficiency compared to traditional worm gearboxes.
- Pelumasan: Proper lubrication plays a significant role in minimizing friction and improving energy efficiency. Using high-quality lubricants and ensuring the gearbox is adequately lubricated can help reduce losses due to friction.
- Application Considerations: While worm gearboxes might have lower energy efficiency compared to other types of gearboxes, they still offer advantages in terms of compactness, high torque transmission, and simplicity. Therefore, the decision to use a worm gearbox should consider the specific requirements of the application, including the trade-off between energy efficiency and other performance factors.
When selecting a worm gearbox, it’s essential to consider the trade-offs between energy efficiency, torque transmission, gearbox size, and the specific needs of the application. Regular maintenance, proper lubrication, and selecting a well-designed gearbox can contribute to achieving the best possible energy efficiency within the limitations of worm gearbox technology.
Mencegah Backlash pada Gearbox Cacing
Kelonggaran (backlash) pada gearbox cacing dapat menyebabkan penurunan akurasi, kesalahan posisi, dan penurunan efisiensi secara keseluruhan. Berikut adalah langkah-langkah untuk mencegah atau meminimalkan kelonggaran:
- Komponen Berkualitas Tinggi: Gunakan roda gigi cacing dan roda cacing berkualitas tinggi dengan toleransi manufaktur yang ketat. Komponen presisi akan membantu mengurangi celah (backlash).
- Penyusunan Jaringan yang Tepat: Pastikan roda gigi cacing dan roda gigi cacing sejajar dan terhubung dengan benar. Penyambungan yang tidak tepat dapat menyebabkan peningkatan celah (backlash).
- Pramuat: Memberikan sedikit beban awal pada roda gigi cacing dapat membantu mengurangi celah balik. Namun, beban awal yang berlebihan dapat meningkatkan gesekan dan keausan.
- Mekanisme Anti-Reaksi Balik: Pertimbangkan untuk menggunakan mekanisme anti-backlash, seperti sistem pegas atau shim yang dapat disetel, untuk mengkompensasi backlash yang ada.
- Pelumasan: Pelumasan yang tepat dapat mengurangi gesekan dan berperan dalam meminimalkan celah balik. Gunakan pelumas yang memberikan kekuatan lapisan film yang baik dan mengurangi keausan.
- Pemeliharaan: Lakukan inspeksi dan perawatan rutin pada gearbox untuk mengidentifikasi dan mengatasi setiap perubahan pada celah (backlash) seiring waktu.
It’s important to strike a balance between reducing backlash and maintaining smooth operation. Consulting with gearbox experts and following manufacturer guidelines will help you optimize your worm gearbox’s performance while minimizing backlash.
