The main function of the excavator center joint is to connect the hydraulic pipelines between the fixed and rotating parts of the entire hydraulic system, allowing the upper and lower sections of the hydraulic pipeline to have a relative rotational movement of 360 degrees.
The excavator center joint, also known as the central rotary joint or hydraulic rotary joint, is widely used in excavators. Its working principle and mechanism allow the hydraulic pipelines to rotate freely between the fixed and rotating parts, without being restricted by mechanical limitations. This design allows excavators to flexibly rotate their working devices during operations such as excavation, loading, and other tasks, without worrying about hydraulic pipeline connections.
Specifically, the internal structure of the excavator center joint includes two precision bearings, ensuring smooth and durable operation of the joint, as well as robustness and flexibility. Due to its low friction coefficient, it can support high-speed rotation. This design not only improves the efficiency of excavators but also enhances their safety and reliability. In addition, the hydraulic rotary joint has a wide range of applications and can be used not only in excavators but also in other equipment such as tunnel boring machines that require hydraulic rotation. Different connection methods can be chosen according to different working situations to maximize efficiency.
In summary, the excavator center joint greatly enhances the performance and efficiency of construction machinery such as excavators through its unique design and functionality. It is an essential and important component in modern construction machinery.
