Description
Technical field
The utility model belongs to piston ring field, particularly relates to a kind of symmetry and takes overlapped piston ring.
Background technique
Piston ring is widely used on various dynamic power machine, as steamer, diesel engine, petrol engine, compressor, hydraulic press etc., piston ring is a kind of metal ring entering piston groove inside for down, it has the metallic elastic expanding outwardly more greatly distortion, is mounted in its corresponding circular groove of section.Piston ring is divided into two kinds: compression ring and machine oil ring.Compression ring can be used to the burning mixture of sealing combustion indoor; Machine oil ring is then used for striking off machine oil unnecessary on cylinder, back and forth and the piston ring of rotary motion, relies on the pressure difference of gas or liquid, seals at ring periphery and cylinder and being formed between ring and a side of annular groove.Along with the prolongation of internal combustion engine time, the otch of piston ring progressively can increase along with the wearing and tearing of piston ring external diameter and cylinder inner wall, the tightness of piston ring is reduced, cause the power dropping of internal-combustion engine or compressor, motor car engine oil consumption constantly increases, and the user cost of machine constantly increases, for reducing oil consumption, need piston ring be regularly replaced, but more rering intricate operation, waste time and energy.
Patent 201020518216.4 provides a kind of piston ring, comprise cock body and gap, the both sides in described gap are respectively first end and the second end of described cock body, it is characterized in that, a seal recess is had in the outer upper end of described first end, a sealing flange corresponding with described seal recess is provided with in the outer upper end of described the second end, when being installed on when described piston ring in the piston groove on piston outer wall, described seal recess is mated mutually with sealing flange, with the gas in sealing air cylinder, but this patent is owing to utilizing, seal recess and sealing flange form radial sealing surfaces, the radial sealing surfaces formed is short, the working life of piston ring can be extended, but the time extended is short, and first end is different with the second end structure, manufacturing procedure is many, manufacturing efficiency is low, promisingly again make sealing flange and seal recess lapping, sealing flange is made to make length long, reduce the mechanical strength of sealing flange, Long-Time Service, easy distortion, reduce the working life of piston ring.
Summary of the invention
For solving the problem, the utility model provide a kind of reasonable in design, structure is simple, sealing is good, long service life, a kind of symmetry efficiently easy to process take overlapped piston ring, comprise piston ring body, described piston ring body is provided with opening, it is characterized in that: top one end exterior periphery of described opening being formed an outer lug boss A, described outer lug boss A caves inward and forms recess A; The bottom of the outwardly formation outer lug boss B in position that the other end of described opening is corresponding with described outer lug boss A, described outer lug boss B caves inward and forms recess B; Be axial slices inside the two ends of described opening, make the two ends of described opening form symmetrical " L " type; Described outer lug boss A and recess B matches, and described outer lug boss B and described recess A matches; When piston ring closes, the mutual lapping of described outer lug boss A and outer lug boss B, the face of mutual lapping is radial sealing surfaces, and the axial surface of contact of described outer lug boss A and described recess B is axial seal face A; The axial surface of contact of described outer lug boss B and described recess A is axial seal face B.
When described piston ring is installed in piston groove, the inner side joint of piston ring forms gap A, described outer lug boss A and described recess B bottom formation gap B; Clearance C is formed at the top of described outer lug boss B and described recess A; Described gap A, gap B and clearance C are blind hole structure, and described gap A is between described gap B and clearance C.
Described outer lug boss A is equal with outer lug boss B length.
Thickness and the thickness equaling piston ring of described outer lug boss A and outer lug boss B.
The thickness of outer lug boss A and outer lug boss B is the half of piston ring thickness.
The beneficial effects of the utility model are: in use, along with the wearing and tearing of piston ring, the rigidity of piston ring own stretches, when lapping position cannot be engaged, produce gas leakage, by outer lug boss A and outer lug boss B is set to symmetric equal-length, under identical Opening length, circumference lapping length is longer, makes the longer service life of piston ring; By arranging boss A, boss B, recess A and recess B, when piston ring is installed in piston groove, boss A and boss B is interlocked lapping, boss A is contained in recess B, boss B is contained in recess A, the axial seal face formed and radial sealing surfaces, stop axially and the spilling of radial gas simultaneously; During use, gap A, gap B and clearance C are blind hole structure, gap A is between gap B and clearance C, make piston ring closer to zhou duicheng tuxing, gas in piston ring acts on the power of gap A, and the power being reacted on boss A and boss B by piston groove is impartial, and boss A and boss B is not easily damaged, piston ring is not yielding simultaneously, extends the working life of piston ring; Opening two ends are designed to symmetric shape, make the length of boss A and boss B relative to unidirectional lapping, shorten length, mechanical strength is higher, longer service life, the utility model reasonable in design, ingenious, processing is simpler, quick, manufacturing efficiency is high, has higher use value and market value.
