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.

Impact of Gear Ratios on Machinery Performance in Agricultural Gearboxes
The gear ratio in agricultural gearboxes plays a crucial role in determining the performance of machinery. It directly affects the relationship between the input and output speeds and torques. Here’s how gear ratios influence machinery performance:
- Speed and Torque Conversion: Gear ratios allow for the conversion of speed and torque between the input and output shafts. Higher gear ratios can reduce output speed while increasing output torque, making it suitable for tasks requiring high power.
- Power and Efficiency: Gear ratios affect the efficiency of power transmission. While reducing the speed through higher gear ratios can increase torque, it’s essential to strike a balance to maintain efficiency. Lower efficiency can lead to energy loss and increased heat generation.
- Task Adaptability: Different agricultural tasks require varying levels of torque and speed. Gear ratios enable machinery to be adaptable to different tasks by providing the necessary torque for heavy-duty activities like plowing or tilling and higher speeds for tasks like transport.
- Optimal Performance: Selecting the appropriate gear ratio ensures that machinery operates within its optimal performance range. It prevents overloading the engine or the gearbox, contributing to smoother operation and reduced wear and tear.
- Productivity and Fuel Efficiency: Proper gear ratios can enhance the overall productivity of agricultural machinery. By optimizing torque and speed, tasks can be completed efficiently, reducing the time and fuel consumption required for operations.
- Consideration of Terrain: Different terrains and field conditions require adjustments in gear ratios. Steep slopes or heavy soil may necessitate lower gear ratios for increased torque, while flat terrain could benefit from higher ratios for faster operation.
- Impact on Components: Gear ratios can influence the load distribution on gearbox components. Higher gear ratios might subject components to increased forces and stresses, potentially affecting their lifespan.
- Operator Comfort: Proper gear ratios contribute to operator comfort by providing the necessary power for smooth operation without straining the machinery. This can lead to reduced operator fatigue and improved safety.
- Customization: Some modern agricultural equipment offers adjustable or variable gear ratios, allowing operators to fine-tune machinery performance based on specific tasks and conditions.
Choosing the right gear ratio for agricultural gearboxes involves considering factors such as the intended task, soil conditions, and equipment specifications. It’s essential to strike a balance between torque and speed to achieve optimal machinery performance and maximize productivity.

Veel voorkomende tekenen van slijtage aan de tandwielkast en de oplossingen daarvoor
Tandwielkasten kunnen, net als alle mechanische onderdelen, na verloop van tijd slijtage vertonen door factoren als wrijving, belasting en bedrijfsomstandigheden. Het herkennen van de gebruikelijke tekenen van slijtage aan de tandwielkast is essentieel voor tijdig onderhoud en het voorkomen van mogelijke storingen. Hier zijn enkele tekenen waar je op moet letten en de oplossingen om ze aan te pakken:
- Ongewone geluiden: Malende, klikkende of zeurende geluiden tijdens het gebruik kunnen duiden op versleten tandwielen of lagers. Inspecteer de tandwielkast op beschadigde tanden of onvoldoende smering. Vervang beschadigde onderdelen en zorg voor een goede smering.
- Verhoogde trillingen: Overmatige trillingen duiden op een verkeerde uitlijning of onbalans in de versnellingsbak. Controleer of de onderdelen goed zijn uitgelijnd en balanceer ze indien nodig. Controleer ook op versleten of beschadigde assen of lagers.
- Lekkage: Lekkage van olie of smeermiddel kan duiden op versleten afdichtingen of pakkingen. Vervang afdichtingen en pakkingen om lekkage te voorkomen en voor voldoende smering te zorgen.
- Slippende versnellingen: Versnellingen die wegglijden of moeilijk schakelen kunnen wijzen op versleten of beschadigde tandwieltanden. Controleer de tandwielen op tekenen van slijtage of afschilfering en vervang ze indien nodig.
- Temperatuurverhoging: Abnormale warmteontwikkeling kan het gevolg zijn van verhoogde wrijving door versleten onderdelen. Controleer het niveau en de kwaliteit van de smering en vervang versleten lagers of tandwielen die te veel wrijving veroorzaken.
- Verminderde prestaties: Verminderde vermogensoverdracht of uitgangsefficiëntie kan duiden op slijtage in de tandwielkast. Controleer tandwielen, lagers en andere onderdelen op tekenen van slijtage en vervang deze indien nodig.
- Overmatig spelen: Overmatige speling in tandwielen kan duiden op versleten tandwieltanden of lagers. Controleer de onderdelen op slijtage, pas de speling aan en vervang versleten onderdelen.
Om slijtage aan de tandwielkast tegen te gaan, is routineonderhoud nodig, waaronder de juiste smering, uitlijncontroles en regelmatige inspecties. Tijdige vervanging van versleten of beschadigde onderdelen kan de levensduur van de tandwielkast verlengen en zorgen voor optimale prestaties in verschillende toepassingen.
