Abstract
A non-contacting gas sealing device for a shaft (1) - having a seal housing (2), a stator seal ring (3) arranged in the seal housing (2), and a rotor seal ring (4) arranged on the shaft (1) and fixed to it. The two seal rings (3)(4) interact by means of their seal end faces (3a)(4a) with the interposition of the gas barrier. In the operating condition and under a predetermined differential operating pressure, the stator seal ring (3) has an annular functioning gap (F) relative to a shaft-side cylindrical part of the seal housing (2), the said gap being sealed by a rubber or plastics O ring seal (11) arranged in a groove and being pressed against the gas barrier with a contact pressure determined by at least one pressure spring (7). The stator seal ring (3) also consists of a hard seal material with a high thermal conductivity, a high modulus of elasticity and great hardness. The stator seal ring (3) has such a large geometrical moment of inertia that, in the operating condition and under a differential operating pressure, the thickness of the annular functioning gap between the shaft-side cylindrical part of the seal housing and the stator seal ring virtually coincides with the corresponding structurally predetermined annular assembly gap between the cylindrical part and the stator seal ring (3) in all operating conditions and is smaller than 0.4 mm, preferably less than 0.3 mm. The O ring seal is additionally designed as a compensating centring ring for the stator seal ring (3) and, for this purpose, has a hardness which is greater than the extrusion limit for the hardness of the material at the gap width specified and the predetermined differential operating pressure and is smaller than the hardness figure of 90 Shore A according to DIN 53 505. <IMAGE>
