A fixed additional element extends on the side of the axial section of the second ring facing away from the interior, and the rises in the direction of the radial section of the first ring above the axial section of the second ring with a protrusion. The protrusion has a downward slope in the direction of the second ring, to form the gap. | 01-15-2015 |
20160091094 | POROUS MEDIA VENTLESS SEAL - The use of externally-pressurized porous media in shaft sealing for turbomachinery is provided for single seals, tandem seals, double-opposed seals, and a ventless seal. These arrangements provide for significant benefits, such as the following: (a) external pressurization allows frozen seal faces to lift open before rotation, (b) pressure is distributed uniformly across the seal face, as opposed to allowing leakage to pass over it, (c) low flow rates of injected gas are possible, (d) the seal faces are self-defending due to the uniform pressure in the gap, and (e) complete elimination of venting process gas is possible. By employing externally-pressurized porous media sealing, a drastic simplification of seal design, as well as gas treatment and seal panel design, is possible. | 03-31-2016 |

20140151966 | DUAL SEALING ARRANGEMENT FOR FINAL DRIVE GEAR BOX - A final drive transmission includes concentric inner and outer metal face seals at an interface between fixed and rotating housing sections for preventing oil contaminating material from entering the housing. Each face seal includes identical metal face seal rings that are biased into sealing engagement with each by identical frusto-conical elastomeric rings. The metal rings are generally L-shaped in cross section, with the metal rings of the outer face seals being constructed to withstand extreme conditions by making their cross section approximately twice that of the inner metal rings. Together with interface surfaces, the assembled inner and outer face seals define a sealed cavity which contains lubrication oil. A reservoir of oil with an oil level sensor is coupled to the sealed cavity and in this way it is determined whether or not oil is leaking from the cavity so that steps may be taken to avoid a catastrophic failure. | 06-05-2014 |
