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.

760-UV Bronze Gearbox

Designed for the most extreme conditions where an extended output shaft is required.

 

Growers typically use The UMC 760-UV bronze gearbox for the most extreme applications where an extended output shaft is required. The gearbox is designed for higher annual hours of operation while handling the heavy loads experienced on corner systems and lateral move carts as well as the most extreme field conditions where wheel rutting is prominent, soil is heavy, and tower weights are higher.

 

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
• Larger input bearings
• Input shaft guard
• External seal protectors for input and output seals
• 11-Bolt mounting pattern
• Full cycle expansion chamber with aluminum cover
• Filled with extreme pressure worm gear oil
• Steel output shaft
• Tapered roller bearings
• Includes carriage bolts and nuts
• Dual ended input shaft
• Also Available Assembled in the USA

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:

1. Persiapan: Kumpulkan semua alat, perlengkapan, dan peralatan keselamatan yang diperlukan sebelum memulai proses pemasangan.
2. 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.
3. Penyelarasan Poros: Periksa keselarasan poros input dan output. Gunakan alat ukur presisi untuk memastikan bahwa poros-poros tersebut sejajar dan lurus satu sama lain.
4. Penyelarasan Pelat Dasar: Sejajarkan pelat dasar reduktor dengan fondasi atau permukaan pemasangan. Pastikan pelat dasar rata dan sejajar dengan benar sebelum mengencangkannya pada tempatnya.
5. 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.
6. 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.
7. 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.
8. Pengujian Keselarasan: Setelah pemasangan, jalankan reduktor cacing sebentar tanpa beban untuk memeriksa apakah ada suara aneh, getaran, atau masalah ketidaksejajaran.
9. 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.

Bagaimana Cara Menghitung Kecepatan Input dan Output pada Gearbox Cacing?

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:

• Kecepatan Masukan: Kecepatan input (N)₁) adalah kecepatan roda gigi penggerak, yang dalam hal ini adalah roda gigi cacing. Biasanya informasi ini diberikan oleh pabrikan atau dapat diukur secara langsung.
• Kecepatan Output: Kecepatan keluaran (N)₂) adalah kecepatan roda gigi penggerak, yaitu roda gigi cacing. Untuk menghitung kecepatan keluaran, gunakan rumus:

  N₂ = N₁ / (Z₁ * Saya)

Di mana:
N₂ = Kecepatan keluaran (rpm)
N₁ = Kecepatan input (rpm)
Z₁ = Jumlah gigi pada roda gigi cacing
i = Rasio roda gigi (rasio jumlah gigi pada roda gigi cacing terhadap jumlah ulir pada cacing)

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.

Keunggulan Penggunaan Reducer Cacing pada Sistem Mekanik

Reducer tipe cacing menawarkan beberapa keunggulan yang membuatnya cocok untuk berbagai sistem mekanis:

• Rasio Reduksi Gigi Tinggi: Gearbox cacing memberikan pengurangan kecepatan yang signifikan, sehingga ideal untuk aplikasi yang membutuhkan rasio pengurangan gigi yang tinggi tanpa memerlukan banyak gigi.
• Desain Ringkas: Reducer tipe cacing memiliki desain yang ringkas dan hemat ruang, sehingga dapat digunakan dalam aplikasi dengan ruang terbatas.
• Penguncian Otomatis: Gearbox cacing memiliki sifat penguncian otomatis, yang berarti bahwa ulir cacing dapat mencegah roda cacing berbalik arah. Hal ini bermanfaat untuk aplikasi di mana gearbox perlu menahan beban di tempatnya tanpa mekanisme pengereman eksternal.
• Pengoperasian yang Lancar dan Tenang: Gearbox cacing beroperasi dengan gerakan geser di antara gigi-giginya, sehingga menghasilkan pengoperasian yang lebih halus dan lebih tenang dibandingkan dengan beberapa jenis gearbox lainnya.
• Transmisi Torsi Tinggi: Gearbox cacing dapat mentransmisikan torsi dalam jumlah besar, sehingga cocok untuk aplikasi yang membutuhkan keluaran torsi yang kuat.
• Disipasi Panas: Gerakan geser antara ulir cacing dan roda cacing berkontribusi pada pembuangan panas, yang dapat menguntungkan dalam aplikasi yang menghasilkan panas selama pengoperasian.
• Performa Stabil: Reducer tipe cacing menawarkan kinerja yang stabil dan andal, sehingga cocok untuk pengoperasian terus menerus dalam berbagai sistem industri dan mekanik.

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.
