Swing Motor & Gear Box

How does a swing motor gear box work?

2. Working principle of gear box
When the excavator starts, the engine transmits power to the reducer. The reducer converts the motor's power into rotational force and then transmits it to the rotational support. The rotating support rotates the chassis horizontally through the rolling of the steel balls and transmits power to the rotary joint. The rotary joint will transmit power to the arm to realize the rotation of the arm. During the entire process, various components in the gearbox work closely together to complete the excavator's rotation operation.
3. Maintenance methods of gear box
In order to ensure the normal operation of the gearbox, regular maintenance is required. The specific method is as follows:
1. Change the lubricating oil regularly and replace the lubricating oil filter element to prevent impurities in the oil from damaging the gearbox.
2. Regularly check the sealing performance of the gearbox, look for possible oil leakage, and take corresponding maintenance measures.
3. Regularly check the wear of various parts of the gear box and replace seriously worn parts in a timely manner.
4. Clean and inspect the rotating support regularly, clean the impurities and dirt on the steel ball raceway, and add lubricating oil to ensure the normal operation of the rotating support.
【Conclusion】
The gearbox is one of the core components of the excavator and plays a vital role in the work of the excavator. Through the introduction of this article, readers can have a deeper understanding of the structure and working principle of the gearbox, as well as maintenance methods, which will help the use and maintenance of the excavator in the future.
