Note: 1. The allowable output speed is affected by duty cycle, load, and ambient temperature. When the allowable output speed is above NS1, please consult our company about the precautions.
2. Calculate the input capacity (kW) by the following formula.
Input capacity (kW)=2π*N*T/60*η/100*10*10*10 N: output speed (RPM)
T: output torque (nm)
η =  75: reducer efficiency (%)
The input capacity is the reference value.
3. When using the reducer at a low temperature, the no-load running torque will increase, so please pay attention when selecting the motor.

Role of Agricultural Gearboxes in Agricultural Machinery

An agricultural gearbox is a specialized type of gearbox used in various agricultural machinery and equipment. It plays a crucial role in the proper functioning of agricultural equipment by transmitting power and torque from the engine to the different components that perform specific tasks in the field.

Agricultural gearboxes are designed to withstand the demanding conditions of agricultural operations, including exposure to dust, dirt, moisture, and heavy loads. They are commonly used in a wide range of agricultural machinery, including tractors, combines, tillers, sprayers, and more.

The primary functions of agricultural gearboxes include:

  • Power Transmission: Agricultural gearboxes transmit power from the engine to various components, such as wheels, blades, and belts, enabling them to perform their respective tasks.
  • Speed Control: Gearboxes allow operators to control the speed and output torque of agricultural machinery. Different tasks require different speeds and levels of torque, and gearboxes provide the necessary adjustments.
  • Direction Change: Many agricultural operations require changing the direction of rotational motion. Gearboxes enable smooth and efficient direction changes without the need for complex mechanical arrangements.
  • Adaptation to Tasks: Agricultural gearboxes are equipped with various gears and shafts that can be configured to match the requirements of specific tasks, such as plowing, planting, harvesting, and more.

These gearboxes come in different configurations, such as straight-cut gears, helical gears, and planetary gears, depending on the specific application and requirements. The choice of gearbox type, gear ratio, and design factors contribute to the overall performance, efficiency, and durability of agricultural machinery.

Regular maintenance and lubrication are essential to ensure the longevity and reliable operation of agricultural gearboxes. Proper care and upkeep help prevent premature wear and damage, ensuring that the machinery performs optimally throughout the farming seasons.
