[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0020] The invention discloses a device for measuring the resistance distance of a foil dynamic pressure air bearing, such as figure 1 , Including foil dynamic pressure air bearing 1, bearing seat 2, rotating shaft 3, arm lever 4, adjusting lever 5, tension sensor 6, rope 7, fixed pulley 8 and weight 9. The foil dynamic pressure air bearing 1 is fixed in the bearing seat 2. The foil dynamic pressure air bearing 1 and the bearing seat 2 are installed on the rotating shaft 3 together, the rotating shaft 3 rotates, and the bearing seat 2 together with the foil dynamic pressure air bearing 1 Do not move, when the rotating shaft 3 reaches a certain speed, a layer of air film will be generated between the rotating shaft 3 and the foil dynamic air bearing 1 due to the air dynamic pressure, that is to say, between the rotating shaft and the foil dynamic air bearing 1 T...
