Transmission Core Components

Power 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

Transmission Gear are vital components in machinery, particularly in heavy-duty equipment such as tractors, harvesters, and construction machinery. These gears play a crucial role in transmitting power from the engine to the wheels, ensuring smooth and efficient operation. Designed for durability, Transmission Gear are made from high-quality materials like steel and alloy to withstand the immense stresses and high temperatures encountered during operation.

Input shaft (one shaft) : usually connected to the spline hole of the clutch driven disk, the center of the end face may have a hole for mounting the clutch friction plate. The shaft is equipped with a drive gear, which varies according to the design of the gearbox. Some of the drive gear may be integrated with the shaft, while the drive gear of other gears may be empty set on the shaft through a needle roller bearing, and a synchronizer will be installed on the input shaft to achieve smooth shifting.
Output shaft (two shafts) : generally directly connected with the drive shaft (drive shaft), the shaft is equipped with a driven gear, which meshes with the driving gear on the input shaft. Part of the gear shift is driven by needle roller bearings, part is splined on the shaft, and there is also a synchronizer to ensure the smoothness and accuracy of the shift. At the rear end of the output shaft there is usually a spline for connecting with the drive shaft to transfer power.
Intermediate shaft (three shafts) and other shafts: In addition to the input shaft and output shaft, some transmissions will also have other shafts such as intermediate shaft. The intermediate shaft is also equipped with gears with different tooth numbers, which plays the role of transition transmission, transferring the power of the input shaft to the output shaft to achieve different transmission ratios.

A transmission shaft is a critical part of the powertrain in various machinery, including agricultural equipment, vehicles, and industrial machines. It plays an essential role in transmitting mechanical power from one component to another, ensuring smooth and reliable operation. Often used in combination with gears, couplings, and bearings, transmission shafts help deliver torque from the engine to the wheels or other mechanical systems. Whether it’s a tractor, harvester, or construction equipment, the transmission shaft ensures that power is efficiently transferred for optimal performance.
