Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings.
[0018] refer to Figure 1~Figure 4 , an air suspension frictionless rotating air supply device, comprising an air bearing shaft 1, an air bearing sleeve 3 and a base 7, the air bearing shaft 1 is set in the air bearing sleeve 3, the air bearing shaft 1 and the air bearing sleeve 3, there is a small gap between them, the mating surface of the air bearing shaft 1 and the air bearing sleeve 3 is conical, the base 7 and the bottom surface of the air bearing sleeve 3 are fixed, and there is an air inlet 8 at the bottom of the air bearing sleeve 3, so The bottom of the air flotation shaft 1 forms a high pressure chamber 6 with the air flotation sleeve 3 and the base 7, and the air inlet 8 communicates with the high pressure chamber 6. The air flotation shaft 1 is composed of conical and cylindrical parts. There are conical and cylindrical holes in the center of the float...

An air-suspending friction-free rotary air supply device comprises an air-suspending shaft, an air-suspending sleeve and a base, wherein the air-suspending shaft is mounted in the air-suspending sleeve in an embedded manner; a tiny clearance exists between the air-suspending shaft and the air-suspending sleeve; the matching surfaces of the air-suspending shaft and the air-suspending sleeve are conical; the base is fixed to the bottom surface of the air-suspending sleeve; an air inlet is formed in the bottom of the air-suspending sleeve; a high-pressure cavity is formed among the bottom of the air-suspending shaft, the air-suspending sleeve and the base, and is communicated with the high-pressure cavity; the air-suspending shaft comprises a conical part and a cylindrical part; a conical hole and a cylindrical hole are formed in the center of the air-suspending shaft, and are communicated with the high-pressure cavity; an air outlet is formed in the top of the air-suspending shaft; and at least two groups of throttling holes are uniformly distributed on the conical surface of the air-suspending shaft perpendicularly in the circumferential direction, and are communicated with the high-pressure cavity. The air-suspending friction-free rotary air supply device can supply air continuously without being impacted by air pipe disturbance.
Description
technical field [0001] The invention relates to the field of air flotation. Background of the invention [0002] With the development of science and technology, gas lubrication is often used instead of ordinary mechanical lubrication, and high-pressure gas is introduced into the gap between objects in relative motion to form a gas film, avoiding direct contact to achieve frictionless motion. [0003] Air flotation devices have different ways of forming gas films and different gas supply methods. Usually, the gas pipe is used to introduce gas into the high-pressure chamber, but no matter which gas supply method is used, the air pipe must not disturb the air flotation device. For some Compared with the air flotation device with air source movement, there is a big problem in air flotation gas supply. For example, the side of the vertically placed folding hinges connected by hinges, the bottom uses multiple air bearing pads to realize the frictionless unfolding movement in the ...
