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.

- Dual ended input shaft
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

What are the Noise Levels Associated with Worm Gearboxes?
The noise levels associated with worm gearboxes can vary depending on several factors, including the design, quality, operating conditions, and maintenance of the gearbox. Here are some key points to consider:
- Design and Quality: Well-designed and high-quality worm gearboxes tend to produce lower noise levels. Factors such as gear tooth profile, precision manufacturing, and proper alignment can contribute to reduced noise.
- Gear Engagement: The way the worm and worm wheel engage and mesh with each other can impact noise levels. Proper tooth contact and alignment can help minimize noise during operation.
- Lubrication: Inadequate or improper lubrication can lead to increased friction and wear, resulting in higher noise levels. Using the recommended lubricant and maintaining proper lubrication levels are important for noise reduction.
- Operating Conditions: Operating the gearbox within its specified load and speed limits can help prevent excessive noise generation. Overloading or operating at high speeds beyond the gearbox’s capabilities can lead to increased noise.
- Backlash: Excessive backlash or play between the gear teeth can lead to impact noise as the teeth engage. Proper backlash adjustment can help mitigate this issue.
- Maintenance: Regular maintenance, including gear inspection, lubrication checks, and addressing any wear or damage, can help keep noise levels in check.
It’s important to note that while worm gearboxes can produce some noise due to the nature of gear meshing, proper design, maintenance, and operation can significantly reduce noise levels. If noise is a concern for your application, consulting with gearbox manufacturers and experts can provide insights into selecting the right gearbox type and implementing measures to minimize noise.
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:
- Input Speed: 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.
- Output Speed: 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.
What Industries Commonly Use Worm Reducers?
Worm reducers are versatile mechanical components that find applications in various industries due to their unique advantages and capabilities. Some of the industries that commonly use worm reducers include:
- Material Handling: Worm reducers are widely used in material handling equipment such as conveyors, bucket elevators, and cranes to control movement and manage heavy loads.

- Food and Beverage: Worm reducers are used in food processing and packaging machinery where hygiene and cleanliness are crucial.
- Agriculture: Agricultural equipment like irrigation systems and tractors use worm reducers for controlling rotational motion.
- Mining and Construction: Heavy-duty applications in mining equipment, excavators, and construction machinery benefit from the torque multiplication provided by worm reducers.
- Energy: Wind turbines and solar tracking systems use worm reducers to convert low-speed, high-torque motion into rotational energy.
- Textile: Textile machinery employs worm reducers for controlling speed and tension in weaving and spinning operations.
- Packaging: Packaging equipment relies on worm reducers for precise movement and positioning of packaging materials.
- Medical: Medical devices and equipment often utilize worm reducers for their accuracy and controlled motion.
- Printing: Printing machines use worm reducers to regulate paper feed and ensure consistent printing quality.
Worm reducers’ ability to provide high torque output, compact design, and self-locking characteristics makes them suitable for applications requiring reliable and controlled motion across various industries.
