Product working principle

Excavator travelling motor reducer is the core component of excavator travelling system, and its working principle is very important. The reducer can convert the hydraulic power into mechanical power, providing a powerful driving force for the excavator, so that it can be stably advanced in a variety of complex engineering sites.
Hydraulic pump supply: The hydraulic system of the excavator provides high pressure hydraulic oil through the hydraulic pump. The high pressure hydraulic oil produced by the hydraulic pump is transported to the travelling motor reducer and becomes the power source driving the reducer.
Hydraulic motor: The reducer is equipped with a hydraulic motor, which is the key component of converting hydraulic energy into mechanical energy. The hydraulic motor uses the role of high pressure hydraulic oil to push the gear or plunger inside the hydraulic motor to produce mechanical power.
Gear drive: gear drive mechanism is used inside the reducer. The high speed and low torque power generated by the hydraulic motor is transformed into low speed and high torque power by the different transmission ratios of the gear combination. This deceleration drive enables the excavator to overcome resistance and move forward stably when walking.
Output shaft: The output shaft of the reducer is an important component that outputs the power inside the reducer to the drive sprocket or track. The output shaft transmits the high torque power after deceleration to the drive system and pushes the excavator to walk.
Control valve: The excavator travelling motor reducer is equipped with a control valve for controlling the working state of the hydraulic motor. By controlling the opening and closing of the valve and the flow direction of the hydraulic oil, the walking control of the excavator can be realized, such as forward, backward and stop.
Intelligent system: The modern excavator walking motor reducer is usually equipped with an intelligent control system, which can achieve accurate control of the walking speed. The system intelligently adjusts the output of the hydraulic motor according to the working load and working condition of the excavator to ensure the stability and high efficiency of walking.
Excavator walking motor reducer converts hydraulic energy into mechanical power through hydraulic power transmission, deceleration transmission and walking control, and provides powerful driving power for excavator. Its efficient working principle enables the excavator to advance stably in various engineering sites and complete various complex engineering tasks. The continuous innovation and optimization of excavator walking motor reducer will certainly bring more possibilities and forward power to the field of engineering construction.
