Description
The invention belongs to the mechanical sealing technology field, can be widely used in the mechanical engineering, especially the sealing system of reciprocating machine.
The existing situation of mechanical engineering is, the sealing between the two relative slide members, and as the internal-combustion piston engine in the mechanical engineering, compressor, between the casing wall and piston of pump or the like, between axle and the bearing, used Sealing is piston ring, seal ring or Stamping Steel Ribbon.With the piston ring is example, it is a simple right angle type opening, just an axial stepped shaft is taken mouthful (claiming the ladder mouth again), its history of continuing to use is very remote, so far become and (see that Xi'an Communications University's machinery is that the 41st page of " (internal combustion (IC) Engine Design " Chinese industrial publishing house in October, 1961 Beijing front page compiled by internal-combustion engine teaching and research group, Jilin Industry University internal combustion teaching and research group volume " (theory of internal-combustion engine and design " volume two, the 42nd page of China Machine Press's in July, 1977 Beijing front page).These design proposals all stay inevitably at opening part sews passage, makes sealability not good enough.For compensating its defect, have to again adopt the measure of many rings, make structure complicated, frictional loss increases, and the complete machine dimensional weight increases.Particularly the opening end gap is in operation because of wearing and tearing increasing gradually, sealability descends and must change, causing piston ring to become the shortest part (seeing the 62nd page of above-mentioned " theory of internal-combustion engine and design " volume two) of operating life on the internal-combustion engine, and become the key factor of decision complete machine, car load service cycle.For a long time, " monocycle piston IC engine " studied always by scientific and technological circle, but sews the not success of solution of problem of passage because of piston ring.
US4713867 discloses a kind of piston ring, the end interface of its piston ring is also taken mouth for the multiple row stepped shaft, but because vertical surface of its overlap joint section is a plane, therefore can not guarantee sealing effect, especially in use for some time, take a mouthful place and passage will occur sewing.
The present invention aims to provide a kind of mechanical seal device and production method thereof, makes Sealing not have the passage of sewing and irrelevant with wearing and tearing, thereby improves the reliability and the life-span of sealing, increases work efficiency.
For this reason, the present invention proposes three kinds of relevant design proposals.The compound mouthful scheme of taking of the first, many with the plug ring of working, seal ring etc. are rotatable occasion in groove; It two is to add the link block scheme, is used for the occasion of location such as piston ring, seal ring or delocalization work more; It three is combined crosswise schemes, is used for the occasion of high pressure compressor reinforced seal more.For Stamping Steel Ribbon, above-mentioned three kinds of schemes all can adopt.
In other words, major technique solution of the present invention is:
A kind of mechanical seal device, it comprises the employing Sealing, slide relative part and relative static element, described Sealing opening is the step-like compound mouth of taking of multiple row, it is characterized in that: Sealing is taken a mouthful end gap that is positioned between two primary sealing areas and is the dead angle that nothing is sewed passage, the molded lines of its faying surface in the cross-section of its overlap joint section be one by a primary sealing area on the line of any to another primary sealing area a bit, promptly, the track of faying surface molded lines formation faying surface is parallel with two primary sealing areas, remaining mutual disjunct distance between its adjacent two-part end gap that is separated into by the section of overlap joint, the shape of taking mouthful end can be with technique change, and sealability is constant.
The Sealing opening is the link block embedded structure and is meant a kind of like this structure, promptly embeds a link block movingly at the Sealing opening, makes to constitute the compound mouth structure of taking between Sealing opening two ends and the pin.
Multiple tracks repeats and the compound mouth structure of taking of combined crosswise is meant so a kind of combination, promptly the sealing system multiple tracks of identical or inequality compoundly taking mouth structure, adding pin structure is combined reinforced seal with acquisition extreme pressure occasion.
The manufacture method of aforesaid mechanical seal device, it may further comprise the steps:
According to the faying surface molded lines precision machining is carried out in the end of Sealing, make the sealing of corresponding faying surface shape.
With a plurality of narrow ring assembly weldings is a cover or a Sealing, the narrow ring of being processed into by the faying surface molded lines carries out pickling plating layer of copper, gets up to do Diffusion Welding by the combination of shapes of global design then, and cylindrical and the radial plane to the domain is finish-ground to Sealing at last, perhaps
Domain cutting becomes a Sealing, that is, the blank that elder generation has opened mouth with pattern to roughing processes a faying surface of taking the mouth place respectively to two ends, and in the circle mould, fit to process under the state to encircle then and carry on the back, fine grinding cylinder, heat setting becomes Sealing, perhaps,
Process cylindrical pin notch and dividing plate respectively, promptly, process the cylindrical body of fluting earlier, processing the groove that communicates behind the location on the precise clamp then, again in midline cut one with every the wide groove in boundary and in groove, embed the dividing plate of a slice stationary fit, a correct grinding pin fitting surface promptly obtains required not connected symmetrical notch at last, perhaps
Two combined methods of cylindrical pin, promptly, on a cylindricality end face, mill out earlier the tenon degree of lip-rounding shape that matches with the compound end shape of taking mouthful Sealing, downcut the post sheet in top, be welded on this post sheet counter-rotating on the pin head and the fine finishing end face again, thereby make and the compound mouthful cylindrical pin of Sealing precision-fit of taking.
