Abstract
The utility model relates to an inlay ring ship engine piston, including top and skirt section, two rings of first annular grooves and round second annular groove have been seted up in the skirt section on being close to the lateral surface at top, and the second annular groove sets up between two rings of first annular grooves. The cross sectional shape of first annular groove is isosceles trapezoid, and the cross sectional shape of second annular groove is semi -circular, and the bottom surface of second annular groove is the arc surface. Install triangular sealing ring in the first annular groove, triangular sealing ring's a triangle -shaped apex angle is outer protruding to first annular groove, installs O type sealing washer in the second annular groove. The utility model discloses a triangular sealing ring is the line contact with the cylinder body internal surface, and when guaranteeing sealed effect, the piece that produces in the cylinder body can not block on the sealing washer, sets up round O type sealing washer between two rings of triangular sealing ring again, has further guaranteed sealed effect.
Description
Technical field
The utility model relates to a kind of marine engine piston, inlays ring marine engine piston in particular to one.
Background technology
Piston is the core work parts of diesel engine, and existing ship engine piston comprises piston body, and the periphery of piston body has offered piston ring groove, and the cross section of piston ring groove is rectangle or semicircle, installs O RunddichtringO in piston ring groove.
The sealing-ring of this kind of structure and annular groove design so that sealing-ring is that face contacts with inner surface of cylinder block. When producing chip in cylinder body, and when chip touches sealing-ring, need repeatedly to rub due to sealing-ring and inner surface of cylinder block so that chip scratch inner surface of cylinder block, is even stuck on sealing-ring, impact sealing effect.
Practical novel content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, and the utility model provides a kind of edge ring marine engine piston.
The utility model solves the technical scheme that its technical problem adopts: a kind of edge ring marine engine piston, comprise top and skirt section, described top and skirt section are formed in one structure, two circle first annular recessess and a circle second ring groove are being offered in described skirt section on the outer side at top, described first annular recesses and second ring groove all outer side circumference around described top arrange, and second ring groove is arranged between two circle first annular recessess.
The cross-sectional shape of described first annular recesses is isosceles trapezoid, and on corresponding cross section, the bottom surface of the first annular recesses the longer base of isosceles trapezoid, and on the corresponding cross section of the opening of the first annular recesses the shorter base of isosceles trapezoid; The cross-sectional shape of described second ring groove is semicircle, and the bottom surface of second ring groove is circular arc face.
Being provided with trilateral sealing-ring in described first annular recesses, a vertex angle of described trilateral sealing-ring, to the first annular recesses outer lug, is provided with O RunddichtringO in described second ring groove.
The upper surface at described top has offered combustion chamber.
First annular recesses and second ring groove are parallel to each other between two, and the center of circle of the first annular recesses and second ring groove is located along the same line and the central axis coaxial in this straight line and described skirt section.
The beneficial effects of the utility model are, one edge ring marine engine piston of the present utility model, trilateral sealing-ring is set in the first annular recesses, trilateral sealing-ring and inner surface of cylinder block are linear contact lay, while ensureing sealing effect, the chip produced in cylinder body can not be stuck on sealing-ring, arranges a circle O RunddichtringO again, further ensure sealing effect between two circle trilateral sealing-rings.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is illustrated further.
Fig. 1 is a kind of structural representation inlaying ring marine engine piston of the present utility model.
Fig. 2 is a kind of cross-sectional view inlaying ring marine engine piston of the present utility model.
Fig. 3 is the partial enlargement figure at A place in Fig. 2.
In figure 1, top, 2, skirt section, the 3, first annular recesses, 31, longer base, 4, second ring groove, 41, circular arc face, 5, trilateral sealing-ring, 6, O RunddichtringO, 7, combustion chamber.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now. These accompanying drawings are the schematic diagram of simplification, only with illustration, basic structure of the present utility model are described, therefore it only shows the formation relevant with the utility model.
As Figure 1-3, one edge ring marine engine piston of the present utility model, comprises top 1 and skirt section 2, and described top 1 and skirt section 2 are formed in one structure, and the upper surface at described top 1 has offered combustion chamber 7.
Two circle first annular recesses 3 and circle second ring grooves 4 are being offered in described skirt section 2 on the outer side at top 1, described first annular recesses 3 and second ring groove 4 all outer side circumference around described top 1 arrange, and second ring groove 4 is arranged between two circle first annular recessess 3. First annular recesses 3 and second ring groove 4 are parallel to each other between two, and the center of circle of the first annular recesses 3 and second ring groove 4 is located along the same line and the central axis coaxial in this straight line and described skirt section 2.
The cross-sectional shape of described first annular recesses 3 is isosceles trapezoid, and on corresponding cross section, the bottom surface of the first annular recesses 3 the shorter base of isosceles trapezoid on the corresponding cross section of opening of longer base 31, first annular recesses 3 of isosceles trapezoid; The cross-sectional shape of described second ring groove 4 is semicircle, and the bottom surface of second ring groove 4 is circular arc face 41. In Fig. 1, the first annular recesses 3 and second ring groove 4 also do not install sealing-ring.
As Figure 2-3, being provided with trilateral sealing-ring 5 in described first annular recesses 3, a vertex angle of described trilateral sealing-ring 5, to the first annular recesses 3 outer lug, is provided with O RunddichtringO 6 in described second ring groove 4.
One edge ring marine engine piston of the present utility model, in first annular recesses 3, trilateral sealing-ring 5 is set, trilateral sealing-ring 5 and inner surface of cylinder block are linear contact lay, while ensureing sealing effect, the chip produced in cylinder body can not be stuck on sealing-ring, a circle O RunddichtringO 6 is set between two circle trilateral sealing-rings 5 again, further ensures sealing effect.
Taking above-mentioned according to desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff in the scope not deviateing this practical new technique thought, can carry out various change and amendment completely. The content that the novel technical scope of this practicality is not limited on specification sheets, it is necessary to determine its technical scope according to right.
