Rotary air supply device unaffected by air pipe bending disturbance

Abstract

The invention relates to a rotary air supply device unaffected by air pipe bending disturbance. The device comprises an air floatation shaft, an air floatation sleeve, an air storage sleeve, an end cover and a base, wherein the air floatation shaft is sleeved in the air floatation sleeve, and a small clearance exists between the air floatation shaft and the air floatation sleeve; the air floatation sleeve is sleeved in the air storage sleeve, and the bottom of the air floatation sleeve and the base are fixed together; the air floatation sleeve, the base, the air storage sleeve form a high pressure chamber at the bottom of the air floatation shaft; the air storage sleeve is provided with an air inlet, which is communicated with the high pressure chamber; an axial through hole is formed at the center of the air floatation shaft; the top end of the air floatation shaft and the end cover with an air outlet hole are fixed together; the air floatation sleeve is provided with a blind hole from the side of the high pressure chamber to form an air intake hole; the air floatation sleeve is provided with radial throttling orifices along the circumferential direction; the number of the throttling orifices is at least two groups; sealing recesses are formed at both sides of the throttling orifices; the air floatation sleeve is provided with air release holes at the side close to the high pressure chamber; air release grooves are formed at the outer circle of the circumference in which the air release holes are located; the air release holes and the air intake hole form included angles and are isolated from each other; and through holes are formed in the air storage sleeve along the radial direction and are communicated with the air release grooves to form air vent holes. The rotary air supply device unaffected by air pipe bending disturbance has the beneficial effects that air supply can be carried out continuously and is not affected by air pipe disturbance.

Description

technical field [0001] The invention relates to the field of air flotation. Background technique [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 plane, ...
