Abstract
The invention relates to a multi-sealing structure. The multi-sealing structure comprises a mounting base 1, a sealing bush 2, a sealing seat 5, a threaded sealing ring 6, an oil retaining disk 7, a rotary shaft 3 and a bearing 4. The bearing 4 is installed on the rotary shaft 3. The oil retaining disk 7 and the threaded sealing ring 6 are sequentially arranged on one side. The sealing bush 2 is installed on an outer ring of the bearing 4 in a matched mode and installed on the mounting base 1. The sealing seat 5 is further fixedly installed on the mounting base 1. The inner diameter of the sealing seat 5 is coated with graphite. Sealing comb teeth are arranged on the outer diameter of the oil retaining disk 7. The multi-sealing structure can realize sealing between high-pressure and high-rotation-speed components, is good in sealing effect, and has the advantages of being long in service life, good in reliability and the like.
Description
Technical field
The present invention relates to a kind of sealing configuration, especially a kind of multi-sealing structure.
Background technique
Existing mechanical system has multiple dynamic seal apparatus, in order to realize the lubricating oil stoping between sound parts, reveal, use and include comparatively widely threaded sealing structure, castor tooth sealing configuration, graphite grazing structure etc. at present, then for some mechanical systems, as aeroengine, its inner chamber lubricating oil pressure is high, dynamic component rotational velocity is high, current conventional sealing configuration or effect are undesirable, or working life is low, can not meet the requirement of system.
Summary of the invention
The object of this invention is to provide a kind of sealing configuration, can realize the sealing between high pressure, high-revolving parts, realize good sealing effect, the feature such as the life-span is high, good reliability.
Technological scheme of the present invention is, multi-sealing structure comprises fitting seat, seal cartridge, sealing seat, thread seal ring, oil baffle disc, running shaft, bearing, bearing is arranged on running shaft, one side is located by the shaft shoulder arranging on running shaft, opposite side be disposed with oil baffle disc, thread seal ring, the internal diameter of described thread seal ring is stepped shaft, the part that diameter is little and oil baffle disc are fixed on running shaft and with running shaft synchronous rotary, the interior loop contacts of oil baffle disc and bearing, on the outer shroud of bearing, coordinate seal cartridge is installed, described seal cartridge is arranged on fitting seat, on fitting seat, be also installed with sealing seat, the internal diameter of seal cartridge coordinates with the external diameter of oil baffle disc, the internal diameter that external diameter is large with the diameter of thread seal ring coordinates, the external diameter of thread seal ring coordinates with the internal diameter of sealing seat, on the inner-diameter portion whose that the diameter of described thread seal ring is large and external diameter, be provided with sealing thread, the internal diameter of sealing seat scribbles graphite, on the external diameter of oil baffle disc, be provided with sealing castor tooth.In described multi-sealing structure, a side of low fuel pressure is provided with compressed air cell, and described compressed air cell is connected with high-pressure air pipe.On described oil baffle disc, be provided with disc, described disc is positioned at compressed air cell, and a side relative with bearing is provided with inclined-plane.On the external diameter of described sealing seat, be provided with big sealing ring, on the internal diameter of oil baffle disc, be provided with small sealing ring with the position of thread seal loop contacts.
The present invention has used the forms such as thread seal, the sealing of castor tooth, graphite grazing, good sealing effect, simple in structure, easy processing and assembling.In multiple whorl seal arrangement, oil baffle disc is set, the lubricating oil stopping and collect is got rid of to bearing, bearing is lubricated with cooling, and stop the lubricating oil of lubricating bearings to flow out.In addition, in this structure, also from gas compressor, introduce pressurized air, utilize pressurized air to form a hyperbaric chamber, oppositely promote fluid and reflux, further enhanced leaktightness effect.The present invention can realize the sealing between high pressure, high-revolving parts, realizes good sealing effect, has the life-span high, the features such as good reliability.
