Principle of excavator walking motor
1. Introduction
Excavators, as a heavy-duty construction machinery, are widely used in fields such as earthwork excavation, mining, and construction. The walking motor of the excavator is one of the important components to achieve its walking function. This article will introduce the principle and working mode of the excavator walking motor.
2. The function of the walking motor
The walking motor of the excavator is mainly used to provide driving force, enabling it to walk freely on the construction site. The walking motor converts hydraulic energy into mechanical energy, driving the excavator's tracks or tires to move forward, backward, and turn.
3. The principle of a walking motor for excavators is based on hydraulic transmission technology. There is a hydraulic motor inside the motor, which is mainly composed of oil cylinders, pistons, gears, valve cores, etc. When hydraulic oil enters the motor through the oil pipe, the piston is subjected to pressure and begins to move. The rotation of the gears converts hydraulic energy into mechanical energy, driving the excavator's tracks or tires for walking.
4. The working mode of the walking motor in excavators can be divided into two types: hydraulic transmission and hydraulic transmission.
1 Transmission
Hydraulic transmission is a method of converting hydraulic energy into mechanical energy through a hydraulic motor. The gears and valve cores inside the hydraulic motor will adjust the speed according to the pressure changes of the hydraulic oil, thereby achieving the walking of the excavator.
2 force transmission
Hydraulic transmission is a method of converting hydraulic energy into mechanical energy through a hydraulic torque converter. The internal hydraulic torque converter adjusts the flow and pressure of hydraulic oil to change the output torque, thereby controlling the walking speed and force of the excavator.
5. Advantages of walking motors
The excavator walking motor has the following advantages:
1. High power: The walking motor can provide sufficient driving force to enable the excavator to walk in various complex terrains and working conditions
2. High flexibility: The walking motor can adjust the walking speed and direction according to the operator's instructions to achieve flexible operation
3. Good stability: The walking motor can achieve smooth walking through hydraulic or hydraulic transmission, improving the stability and safety of the excavator
6. Regular maintenance is required to ensure the normal operation of the excavator's walking motor.
Mainly including
1. Cleaning: Regularly clean the external surface of the walking motor to prevent dust and impurities from entering the interior and affecting the working effect.
2. Lubrication: Regularly add lubricating oil to the lubricating parts of the walking motor to ensure normal lubrication of the walking motor
3. Inspection: Regularly inspect the seals, gears, and valve cores of the walking motor for wear and damage, and replace or repair them in a timely manner.
7. Summary
The excavator walking motor is a key component of excavator walking, and its principle is based on hydraulic transmission or hydraulic transmission technology. The walking motor converts hydraulic energy into mechanical energy to drive the excavator's tracks or tires for walking. The walking motor has the advantages of high power, high flexibility, and good stability, and requires regular maintenance to ensure its normal operation. By understanding the principle of the excavator walking motor, it is possible to better use and maintain the excavator, improve work efficiency and safety.
