[0035] The air inlets 14 are equidistantly connected and opened on the inner side of the front side of the outer shell 11;

[0036] The outer shell 11 is the main mounting carrier of the air bearing body and provides external protection, and the air inlet 14 provides the air required by the bearing;

[0037] The air bearing body also includes shaft suspension breathable steel 12, shaft shoulder suspension breathable steel 13, air outlet 15, and connecting shaft 16;

[0038] The shaft suspension breathable steel 12 is symmetrically arranged at the front and rear ends of the outer shell 11, and the shaft shoulder suspension breathable steel 13 is symmetrically arranged at the front end of the front shaft suspension breathable steel 12, the air outlet 15 is equidistantly arranged between adjacent air inlets 14, and the connecting shaft 16 is sleeved in the middle of the outer shell 11;

[0039] The shaft suspension breathable steel 12 and the shaft shoulder suspension breathable steel 13 cooperate with the introduction of gas to meet the rotation requirements of the connecting shaft 16. The gas outlet 15 is used for gas outlet and ventilation. The connecting shaft 16 is connected to the outside to meet the rotation requirements and reduce the friction generated by the rotation.

[0040] The air intake filter unit includes a ring frame 21, a first high-efficiency filter screen 22, and a second high-efficiency filter screen 23;

[0041] The ring frame 21 is arranged in front of the air inlet 14, and the first high-efficiency filter 22 and the second high-efficiency filter 23 are arranged in the front and rear of the inner rear of the ring frame 21, and the apertures of the first high-efficiency filter 22 and the second high-efficiency filter 23 are gradually reduced;

[0042] The ring frame 21 is used to install the first high-efficiency filter 22 and the second high-efficiency filter 23. The first high-efficiency filter 22 and the second high-efficiency filter 23 are used to filter the impurity particles in the introduced air. The gradually decreasing aperture setting can realize graded filtering and improve the use effect.

[0043] The front part of the inner wall of the ring frame 21 is provided with thread grooves 24 at equal intervals, and the rear part of the inner wall of the ring frame 21 is fixed with a thread ring 26;

[0044] The thread groove 24 satisfies the installation between the ring frame 21 and the outside;

[0045] A threaded tube 25 is arranged outside the threaded ring 26, and the two are threadedly fixed, and the threaded tube 25 is fixed to the front end of the inner wall of the air inlet 14;

[0046] The connection between the threaded tube 25 and the threaded ring 26 fixes the ring frame 21 and the air inlet 14. The threaded connection method is conducive to the disassembly and assembly of the structure.

[0047] Working principle: After connecting the connecting shaft 16 to the outside, put the threaded ring 26 into the threaded tube 25 and tighten it to install and fix the ring frame 21 and the air inlet 14;

[0048] Next, the first high-efficiency filter 22 and the second high-efficiency filter 23 are installed at the front and rear positions of the inner rear of the ring frame 21 through the following connection parts, and the ring frame 21 is connected to the external air supply equipment in conjunction with the threaded groove 24;

[0049] Then, when the external air supply device supplies air to the air inlet 14 through the ring frame 21, the supplied gas passes through the first high-efficiency filter 22 and the second high-efficiency filter 23 to filter the impurity particles in the air;

[0050] This solution prevents foreign particles from entering the bearing, affecting component wear and improving performance.

[0055] The width of the magnetic rod 33 is smaller than the inner width of the limit opening 32, ensuring that the thread groove 24 can be used normally, and the arrangement of the anti-slip pattern can meet the application of the disassembly force of the magnetic rod 33;

[0056] Working principle: When installing the first high-efficiency filter 22 and the second high-efficiency filter 23, the ends of the connecting column 31 are pre-fastened with the inner ends of the first high-efficiency filter 22 and the second high-efficiency filter 23 to install and fix the two.

[0057] Next, the magnetic rod 33 is placed in the limiting opening 32, and the inner end of the magnetic rod 33 contacts the outer side of the first high-efficiency filter 22, and the limiting opening 32 and the magnetic rod 33 are in a magnetically fixed state, so that the first high-efficiency filter 22 and the second high-efficiency filter 23 can be fixed in the ring frame 21, and vice versa;

[0058] This solution can conveniently and quickly disassemble the first high-efficiency filter 22 and the second high-efficiency filter 23, saving time and effort.
