Final Drive Parts
How does a final drive parts work?
The final drive of an excavator refers to the transmission system that transmits the power generated by the engine to working devices such as crawler tracks and bucket rods to achieve excavation operations. Through the transmission system, the excavator can travel and turn, and can also realize functions such as up and down rotation of the arm and telescopic insertion of the arm.2. The composition of the final drive of the excavator
The final drive of the excavator mainly consists of the following parts:
1. Main transmission box: The transmission box is the core part of the entire transmission system. The main transmission shaft is used to transmit power to the engine, crawler tracks, and bucket arm devices.
2. Crawler tracks and track wheels: The crawler tracks and track wheels are responsible for the excavator's walking, steering and bearing the vehicle's weight. The power that drives the crawler track comes from the power output by the motor.
3. Oil cylinder and arm: The excavator arm and oil cylinder are the core components of the excavation operation. They realize the up and down rotation of the arm and the telescopic insertion of the arm and other operating functions.
4. Oil circuit and oil pump: The oil circuit and oil pump are responsible for providing power to various parts, so that the crawler tracks, bucket rods, cylinders and other parts can work smoothly.
3. Maintenance of excavator final drive
The final drive of the excavator is a key system of the excavator. To maintain its normal operation, scientific maintenance and upkeep must be carried out. The specific method is as follows:
1. Replace hydraulic oil regularly: Hydraulic oil is an important lubricating medium for the final drive of the excavator. It needs to be replaced every 3,000 hours to ensure that the lubricating oil is clean.
2. Clean the filter regularly: During use, impurities in the oil circuit will continue to deposit. Cleaning the filter regularly can effectively prevent impurities from entering the system and improve the stability and reliability of the system.
3. Regularly check the bearings: The bearings in the final drive are responsible for bearing the heavy load during work. Check and replace damaged bearings regularly to avoid bearing damage from affecting the system.
4. Summary
The final drive of an excavator is a key system for realizing excavation operations. Through the cooperation of the transmission box, crawler tracks, stick and oil circuit, it realizes the functions of excavator walking, steering and stick telescopicity. Paying attention to the maintenance of the excavator's final drive is of great significance to ensure the long-term stable operation of the excavator and extend the service life of the excavator.
