The high-speed rotating joint is provided with a multi-stage clamping ring, wherein the first clamping ring is used for separating the joint main body and the connecting body, so that the joint main body and the connecting body can be quickly arranged on two sides of the rotating shaft respectively during installation; the second clamping ring and the third clamping ring are used for fixing the bearing arranged in the first cavity, and the internal structure of the joint is reasonably arranged, so that the internal structure of the high-speed rotating joint is still stable when the high-speed rotating joint works; the interface of the pagoda-shaped structure can meet the application of certain specific occasions, can be matched with specific equipment for use, and works smoothly. The utility model discloses high-speed rotary joint adopts the structure of through type, and such structure sets up reasonable, convenient assembling, job stabilization is smooth and easy, product long service life's advantage.

This practicality further sets up all to form the seal groove on the inner wall of first cavity and the inner wall of second cavity, be provided with rubber seal in the seal groove.

The rubber sealing element can ensure the sealing performance between the inner wall of the first cavity and the outer wall of the rotating shaft and between the inner wall of the second cavity and the outer wall of the rotating shaft, and leakage is avoided.

This practicality further sets up to the top and the below of bearing all are provided with the retaining ring.

The utility model discloses further set up to the bearing and be provided with two sets ofly, including first bearing and second bearing, the both sides of first bearing and the both sides of second bearing all are connected with the retaining ring, first bearing is connected with the third rand, and the second bearing is connected with the second rand.

The first bearing and the second bearing are fixed in the first cavity through the retainer ring, and are further limited and separated by the retainer ring, so that the working stability of the bearing on the rotating shaft is improved.
