Rotary Tiller Gearbox

Rotary Tiller Gearboxes are adopted middle gear transmission systems, mounted with tractors of 12-80HP. Tractor wheel tracks are completely covered after tillage as the working width is much wider. The quality is reliable and the performance is well. So it can be used on dry and paddy fields. They can reduce the time, laboring, cost, etc. during operation.

A rotary tiller gearbox is a complex mechanical structure that bears a dynamic load. A multispeed rotary tiller is a workhorse for professional users and offers three gearbox speeds, each with different power output. A durable gearbox with ideal working speeds ensures optimal tilling performance. A dual PTO system is also available, which operates at separate speeds to increase versatility. These features allow users to use a single tiller for various tasks and soil conditions. These benefits are not only attractive to consumers but also ensure better tilling performance for professionals and heavy-duty users.

Agricultural Gearbox FAQs

What is the agricultural gearbox used?

Agricultural gearboxes are widely used in agricultural machineries, such as lawn mowers, rice harvesters, grain storage warehousing, rotary tillers, etc. To accommodate this application, we have produced different gearboxes, including rotary tiller gearboxes, lawn mower gearboxes, and rice harvester gearboxes.

What is an orthogonal gearbox?
Agricultural gearboxes always have one input shaft and at least one output shaft. If these shafts are positioned at 90° to each other, the gearbox is an orthogonal angle gearbox or more commonly called a right-angle gearbox.
What gear technology is used in a right-angle gearbox?

Typical gear technologies used in the right-angle gearbox include worm gears, spiral bevel gears, and hypoid gears. Each technology offers specific advantages related to efficiency, output torque capabilities, and compactness.

What's the principle of agricultural gearbox?

Manual gearboxes are mainly composed of gears and shafts, which produce variable speed torque through different gear combinations; automatic gearboxes are composed of hydraulic torque converters, planetary gears, and hydraulic control systems, which achieve variable speed torque through the hydraulic transmission and gear combinations.

The manual gearbox hydraulic torque converter is the most distinctive component. It is composed of pump wheels, turbines, and guide wheels, which directly input engine power to transmit torque and clutch. The pump wheel and the turbine are a pair of workbenches. They are like the relative positions of two fans. The active fan blowing will drive the other passive fan blades to rotate, and the airflow-wind has become the kinetic energy transfer medium.

If the liquid replaces air as the kinetic energy conversion medium, the pump wheel will be driven by the rotation of the liquid turbine, and then the transmission efficiency of the liquid between the pump wheel and the turbine will be improved.

What's the function of agricultural gearbox?
  • Changing the transmission direction, for example, we can use two sector gears to transfer the force vertically to another rotating shaft.
  • Change the rotational torque. Under the condition of the same power, the faster the gear rotates, the smaller the torque on the shaft, and vice versa.
  • Clutch function: we can separate the engine from the load by separating two meshing gears. Such as brake, clutch, etc.
  • Distribute power. For example, we can use an engine to drive multiple slave shafts through the main shaft of the gearbox, so as to realize the function of one engine driving multiple loads.

Precautions for using an agricultural gearbox

The gearbox of agricultural machinery is a key component of agricultural machinery. Its main functions include: achieving the purpose of changing speed and torque through hydraulic transmission and gear combination; Change the transmission ratio; When the rotation direction of the engine remains the same, the agricultural machine is driven backward; Use neutral gear to interrupt power transmission, so that the engine can start and idle, and facilitate transmission shift or power output. In the long-term use process, some faults and abnormal noises can not be avoided.

First of all, we should regularly check the technical status of the steering device and positioning system of the gearbox of agricultural machinery. Regularly check the positioning of the front wheels and the special devices, and take important measures to reduce the deformation and damage of the walking parts. The inspection should be carried out according to the values required by various tractors. Each type is different, so you can see the instructions provided by the factory to understand the problem. In particular, whether the fixed nuts of the main shaft and the cross bar are tightened.

The operation shall be carried out strictly in accordance with the operating specifications. When starting, it shall be stable. When driving on an uneven road, it shall be slowed down. It is not allowed to overtake the ditch at high speed or turn sharply at high speed, which will cause faults and be prone to danger. During transportation, keep driving at a medium speed, try not to use the emergency braking device, and do not let the gearbox work overload frequently.

The operation shall be carried out strictly. When starting, the gearbox of the agricultural machinery shall be kept rotating smoothly. When driving in the field and on uneven roads, remember not to turn sharply. During transportation, the vehicle shall be at medium speed, avoid emergency braking as much as possible, and do not overload.
