Working principle of the excavator center rotary joint
The excavator center rotary joint is a component that connects the excavator arm and bucket. It allows the excavator to rotate 360 degrees without dead ends without moving the entire vehicle, thereby improving work efficiency. In layman’s terms, it is the important axis of rotation of the excavator.
The center rotary joint of the excavator rotates through an internal gear mechanism or a cycloidal pinwheel mechanism. Specifically, when the excavator arm rotates, the oil enters the inside of the excavator center rotary joint through the oil line, pushing the internal gear or cycloidal pinwheel to deflect, causing the excavator arm and bucket to rotate. At the same time, the internal sealing ring ensures that the oil does not leak.
Advantages of the excavator center rotary joint
- Achieve 360-degree rotation without dead ends: The excavator center rotary joint can realize 360-degree rotation without dead ends, improving the adaptability and flexibility of the excavator at the construction site.
- Easy operation: With the help of the excavator center rotary joint, the excavator can be operated more easily and freely. The excavator operator only needs to control the direction of the excavator through the handle or foot pedal, which is simple to operate.
- Improve work efficiency: Using the excavator center rotary joint can optimize the construction environment, reduce construction time, and greatly improve work efficiency and production efficiency.
- Save energy: The rotary joint in the center of the excavator can reduce the time and energy consumption required for the excavator to turn, which is very beneficial to saving fuel.
The center rotary joint of the excavator is one of the important components in the excavating machinery. It realizes the 360-degree rotation of the excavator through an internal gear mechanism or a cycloidal pinwheel mechanism. Its use can improve work efficiency, save energy, and has the advantages of simple operation.
