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

如何正确安装和校准蜗轮减速器
正确安装和校准蜗轮减速器对于确保其最佳性能和使用寿命至关重要。请按照以下步骤安装和校准蜗轮减速器：
- 准备： 安装过程开始前，请准备好所有必要的工具、设备和安全装备。
- 定位： 将蜗杆减速器放置在所需位置，确保其牢固地安装在稳定的表面上。根据需要使用合适的紧固件和安装支架。
- 轴对准： 检查输入轴和输出轴的对准情况。使用精密测量工具确保两轴平行且彼此对齐。
- 底板对齐： 将减速器的底板与基础或安装面对齐。在固定底板之前，请确保底板水平且正确对齐。
- 螺栓拧紧： Gradually and evenly tighten the mounting bolts to the manufacturer’s specifications. This helps ensure proper contact between the reducer and the mounting surface.
- 检查是否符合要求： 确认所有旋转部件或运行过程中可能移动的零件都有足够的间隙。避免任何可能造成损坏或性能问题的干涉。
- 润滑： Apply the recommended lubricant to the worm reducer according to the manufacturer’s guidelines. Proper lubrication is essential for smooth operation and reducing friction.
- 对齐测试： 安装完成后，在不带负载的情况下短暂运行蜗轮减速器，检查是否有任何异常噪音、振动或错位问题。
- 负载测试： 逐步将预定负载施加到蜗轮减速器上，并监测其运行情况。确保减速器在负载条件下平稳高效地运行。
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.
- 润滑： 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.
防止蜗轮蜗杆变速箱出现反冲
蜗轮蜗杆传动装置的反冲会导致精度降低、定位误差增大以及整体效率下降。以下是防止或最大限度减少反冲的步骤：
- 高品质组件： 使用制造公差严格的高质量蜗轮蜗杆和蜗轮。精密部件有助于减少反冲。
- 正确网格划分： 确保蜗轮和蜗杆正确对齐并啮合。啮合不当会导致齿隙增大。
- 预加载： 对蜗轮施加少量预紧力有助于减少齿隙。但是，过大的预紧力会增加摩擦和磨损。
- 防反弹机制： 考虑使用防反冲机制，例如弹簧加载系统或可调节垫片，来补偿任何固有的反冲。
- 润滑： 适当的润滑可以减少摩擦，并有助于最大限度地减少反冲。使用具有良好油膜强度和减少磨损的润滑剂。
- 维护： 定期检查和维护变速箱，以便发现并解决随着时间的推移出现的齿隙变化。
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.
