Abstract
A low-pressure and high-speed rotating connector comprises an elbow and a shell. One end of the shell is arranged in the elbow, a spring is arranged in the shell, a spring cushion is arranged at the right end of the spring, an O-shaped seal ring is arranged at the right end of the spring cushion, a stationary seal ring is arranged at the right end of the O-shaped seal ring, a rotating outer pipe is arranged at the front end of the stationary seal ring, and an oil nozzle is designed on the portion, outside the rotating outer pipe, of the shell. A cylindrical pin is arranged on the portion, outside the stationary seal ring, of the shell. A ceramic ring is arranged at the right end of the stationary seal ring. A dynamic seal is designed at the right end of the ceramic ring. A bearing is arranged between the rotating outer pipe and the shell. An O-shaped ring is arranged outside the bearing. The low-pressure and high-speed rotating connector has the advantages that water and gas serve as media, vibration is reduced by adding the O-shaped ring on the outer circle of the bearing, the rotating connector can be kept in a good stable state, each sealing piece which is prone to damage is designed alone, it is ensured that the rotating connector is convenient to detach and assemble and easy to replace, and the long service life is ensured through the smallest maintenance cost.
