Gear Of Construction Machinery
Transfer power and torque: the power of the engine or other power source is transmitted to the various working parts of the construction machinery, such as the bucket of the excavator, the boom of the loader, etc., so that these parts can produce the required movement and force to complete a variety of tasks.
Change the speed and torque: through the different number of teeth gear mesh with each other, to achieve the speed reduction or increase, while increasing or reducing the torque accordingly, to meet the construction machinery under different working conditions of speed and strength requirements. For example, when the excavator is climbing or digging hard soil, it needs a large torque, and the gear transmission can reduce the speed and increase the torque.
Change the direction of movement: change the direction of power transmission, such as converting the horizontal rotation to the vertical rotation, to adapt to the complex movement needs of construction machinery, such as the rotating mechanism of the crane, steering mechanism, etc.
Peculiarity
High strength and wear resistance: construction machinery usually operates in a harsh working environment and bears a large load and impact force, so construction machinery gears need to be made of high-strength materials, and go through a special heat treatment process to improve the hardness and wear resistance of the gear, to ensure that there will be no tooth surface wear, break and other failure forms during long-term use.
High precision: In order to ensure the smoothness and accuracy of power transmission, reduce vibration and noise, the manufacturing precision of construction machinery gear requires higher requirements. The high-precision gear can make the meshing between the teeth closer, and the transmission error is smaller, so as to improve the efficiency and reliability of the entire construction machinery.
Good impact resistance: In the working process of construction machinery, the gear will often be affected by the impact load, such as the sudden force of the excavator when digging, the collision of the loader when loading and unloading the goods. Therefore, the gear of construction machinery needs to have good impact resistance and can maintain a stable working state under impact load without deformation or damage.
Adapt to harsh environment: construction machinery may work in high temperature, low temperature, humidity, dust and other harsh environment, gear need to have good corrosion resistance, rust resistance and fatigue resistance, to adapt to a variety of harsh working conditions, extend the service life.

Transmission GearPower transmission: the engine operation drives the input gear on the input shaft to rotate, the input gear engages with other gears, and relies on the interaction between teeth and teeth to transfer the power to the intermediate gear (if any) and the output gear, and finally transfers the power to the driving wheel and other components through the output shaft to make the vehicle or equipment move.
Variable speed principle: Change the transmission ratio by meshing gears with different numbers of teeth. For example, when the big gear drives the small gear, the speed of the small gear will be faster than the big gear, but the output torque will be smaller, to achieve growth and torque reduction; On the contrary, when the pinion drives the big gear, the speed of the big gear slows down, the torque increases, and the torque increases. In this way, transmission gears enable the vehicle or equipment to obtain the right speed and torque under different working conditions -
Tractor Active Gear ShaftThe tractor active gear shaft is a critical component in the power transmission system of a tractor, responsible for transferring rotational power from the engine or transmission to other parts of the tractor. By efficiently distributing torque and enabling smooth gear shifts, the active gear shaft plays a vital role in enhancing the performance and versatility of the tractor, making it essential for a wide range of agricultural tasks. In this article, we’ll explore the function, benefits, and maintenance of the tractor active gear shaft.

Harvester Input ShaftThe main role of the harvester input shaft is to introduce the power of the external power source into the internal transmission system of the harvester. When the power source (such as an engine) is running, the torque generated is transmitted to the input shaft through the connecting parts, causing the input shaft to start rotating. The gear, pulley or sprocket and other transmission parts installed on the input shaft will rotate with the rotation of the input shaft, and then transfer the power to the subsequent transmission parts and working parts, such as driving the cutting device, conveying device, threshing device, etc., to complete the crop harvesting, conveying, threshing and other work processes.
