Theory

The excavator gearbox is an important part of the excavator transmission system. Its main function is to transmit the power of the engine to the working device of the excavator through gears to realize operations such as excavation, loading, and steering. The following is the basic principle of the excavator gearbox:

Gear transmission: The excavator gearbox uses gear transmission to realize the transmission of power. A gear is a disc-shaped mechanical part with a series of tooth-shaped protrusions on it. The gearbox usually contains multiple gears, which transmit power through meshing. The larger gear is called the driving gear, and the smaller gear is called the driven gear. The driving gear is powered by the engine and transmits power to the driven gear through the meshing of the gears, thereby driving the working device of the excavator.
Gear ratio: The gears in the gearbox realize the conversion of speed and torque through different sizes of teeth. The gear ratio in the gearbox refers to the ratio of the number of teeth of the driving gear and the driven gear. When the number of teeth of the driven gear is less than that of the driving gear, the transmission ratio is greater than 1, which can achieve torque amplifiion, which is suitable for working conditions requiring large torque output. When the number of teeth of the driven gear is greater than that of the driving gear, the transmission ratio is less than 1, which can achieve speed amplifiion, which is suitable for working conditions requiring high-speed operation.
Gearbox structure: Excavator gearboxes usually consist of multiple gears and shafts. Gears and shafts are supported by bearings to enable smooth rotation. In the gearbox, gears are usually distributed on different parallel shafts, and power transmission is achieved through synchronous meshing. The gearbox may also include accessories such as clutches and brakes to achieve control and protection of the transmission system.
Lubriion system: The excavator gearbox will generate greater friction and heat during operation, so a lubriion system is required to reduce friction, cool and protect the gearbox. The lubriion system usually includes components such as oil pumps, oil tanks and oil pipes to transport lubriing oil to various parts of the gearbox to form a lubriing film to reduce gear wear and friction.
In summary, the excavator gearbox realizes power transmission through gear transmission and speed and torque conversion through gear ratio. The structure is complex and requires a lubriion system to ensure normal operation. The appliion of these principles enables excavators to complete various work tasks efficiently and accurately.
