The working principle of gearbox is mainly to achieve multiple functions through the combination of gears of different sizes, including acceleration and deceleration, changing the direction of force transmission, changing the rotational torque and having clutch function. The specific introduction is as follows:
Acceleration and deceleration: The gearbox achieves acceleration or deceleration by changing the combination and ratio of gears, which is achieved by the meshing of large and small gears. For example, a large gear is installed on the low-speed shaft and a small gear is installed on the high-speed shaft to achieve the effect of deceleration and torque increase.
Changing the direction of force transmission: Through the cleverly designed fan-shaped gears, the gearbox can vertically transmit force from one direction to another shaft to achieve efficient power transmission.
Changing the rotational torque: Under the same power conditions, the torque on the shaft can be changed by adjusting the speed of the gears, which is very useful for application scenarios that require precise control of torque.
Clutch function: By separating two originally meshed gears, the gearbox can separate the engine and the load to achieve power disconnection and connection. This function plays a key role in vehicle starting, shifting and braking.
Power distribution: Through the design of the gearbox main shaft driving multiple driven shafts, the gearbox can realize the function of one engine driving multiple loads. This function is of great significance to improving the efficiency and flexibility of the power system.
