Abstract:
The present invention provides a stator component of a vacuum pump, which is suitable for reducing the fracture energy (energy of fracture that occurs when a rotor of the pump is damaged during its rotation) and the size of the pump, and also provides a vacuum pump having this stator component. In the vacuum pump, a spacer or of a thread groove pump stator, which is a stator component forms a gap satisfying the following <<condition>> between an outer circumferential surface of each of housed in a pump case of the vacuum pump, and an inner circumferential surface of the pump case, with the stator component being housed in the pump case. <<Condition>> 2d/D≤ε max , where D is the outer diameter of the stator component (spacer or thread groove pump stator), d is the width of the gap, and ε max  is the breaking elongation of the stator component.

Claim (Index 1):
A stator component of a vacuum pump, which is an annular stator component housed in a pump case as a component of the vacuum pump that exhausts gas taken in by rotation of a rotor in the pump case, wherein\n the stator component forms a gap which satisfies the following <<condition>> between an outer circumferential surface of the stator component and an inner circumferential surface of the pump case, with the stator component being housed in the pump case, and the stator component is produced by a casting:\n 2 d/D\u2264\u03b5 max \u2003\u2003<<Condition>> \n D: Outer diameter of the stator component d: Width of the gap \u03b5 max : Breaking elongation of the stator component.
