Transmission Shaft
Working Principle
Power transmission: The input shaft receives the power from the engine and turns with the operation of the engine. The gear on the input shaft meshes with the gear on the other shaft, and the power is transmitted to the intermediate shaft (if any) and the output shaft in turn through the transmission of the teeth and teeth between the gears, and finally the power is transmitted to the driving wheel, so that the vehicle can be driven.
Variable speed and torque: By changing the combination of different sizes of gear mesh, to achieve different transmission ratios. When it is necessary to drive at high speed, the transmission ratio between the input shaft and the output shaft will be smaller, that is, the input shaft turns many times and the output shaft turns once, so that the speed of the output shaft will be increased, but the output torque will be reduced accordingly; When it is necessary to climb or need greater traction, it will choose to make the transmission ratio larger, reduce the speed of the output shaft, but increase the torque, so as to meet the needs of the vehicle in different driving conditions
Structural Composition
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.
Application Scenario
Automotive field: In the manual transmission, the transmission shaft realizes the driver's manual shift through the combination of different gears to adapt to different road conditions and driving needs. In the automatic transmission, the transmission shaft is matched with the hydraulic torque converter and planetary gear set, etc., and the hydraulic control system automatically realizes the variable speed and torque, providing a more convenient and comfortable driving experience for the vehicle.
Industrial machinery: In the transmission of various machine tools, the transmission shaft is used to achieve different cutting speeds and feed speeds to meet the requirements of different processing processes. In the transmission system of large industrial equipment such as cranes and conveyors, the transmission shaft distributes and transmits power reasonably, so that the equipment can run stably and efficiently.

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.

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.
