としている。[Problems to be solved by the invention] However, in conventional sealing mechanisms using oil seals and V-packs, the tightness of the seal with the power shaft is determined by the tightening force of the wire for oil seals and the tightening force of rubber for packages. In order to change the adhesion, the oil seal, gasket, and even the dimensions of the power shaft had to be changed. Therefore, in order to solve these conventional problems, the present invention has developed a sealing system that allows adjustment of the tightness with the power shaft without changing the sealing mechanism. The purpose is to obtain 1 mechanism.

Several donut-shaped rubber sheets are installed so that the inner periphery is in close contact with the power shaft, compressed fluid is supplied around the donut-shaped rubber sheets, and the pressure of the compressed fluid is adjusted. It is characterized in that the adhesion between the donut-shaped rubber seal 1 and the doughnut-shaped rubber seal 1 can be adjusted.

５・７・１０の密着部が追従するようにしである。[Example 1] An example of the present invention will be described below based on the drawings using an example of introducing power into a water tank. In FIG. 1, housing 8 and housing 11 are assembled and fixed to water tank 15 by mounting screws 16, and power shaft 4 is introduced into water tank 15 through the center of housing 8 and housing 11. A flange 3 is driven into the upper end of the power shaft 4, and a work set table 1 is fixed to the upper surface of the flange 3 with mounting screws 2. The work set table 1, the flange 3, the water tank 15, and the housing 8 are sealed with an O-ring 12 and an O-ring 14 in between, respectively. Three rubber sheets 5, 7, 10 are rings 6, 13
- It is installed inside the housing 8 in a state where it is sandwiched by the fixing nuts 17, and is fixed by being tightened in the axial direction by the fixing nuts 18. At this time, the inner peripheries of the rubber sheets 5, 7, and 10 are in close contact with the power shaft 4, and the power shaft 4 is sealed at this contact portion. Further, a suitable gap is provided between the rings 6, 13, 17 and the power shaft 4 so that the close contact portions of the rubber sheets 5, 7, 10 follow the movement of the power shaft 4.
継手９より供給された圧縮流体は、ハウジング８とリン

By adopting a structure in which compressed fluid is supplied around the power shaft and the donut-shaped rubber sheet to obtain close contact, the effect is that the pressure of the compressed fluid to be supplied can be adjusted to obtain the necessary close contact. be. Furthermore, the exact same mechanism can be applied to the power shaft introduction part into a vacuum container that requires high vacuum.
