Изобретение относитс к двигателестроению , а именно к поршневым двигател м внутреннего сгорани .FIELD OF THE INVENTION The invention relates to engine construction, in particular to internal combustion piston engines.
Известны цилиндры двигателей внутреннего сгорани ,содержащие рубашку цилиндра, головку и гильзу, а также уплотнительное кольцо газового стыка в головке 1 .Known cylinders of internal combustion engines, comprising a cylinder liner, a head and a liner, as well as a gas joint sealing ring in the head 1.
Недостатком известных конструкций вл етс недостаточна надежность уплотнени газового стыка, вследствие возможности смещени сои гильзы относительно оси цилиндра и головки , которое может возникнуть из-за неточности изготовлени деталей и при изменении теплового режима работы двигател .A disadvantage of the known constructions is the insufficient reliability of the gas butt joint seal, due to the possibility of displacing the soybean sleeve relative to the cylinder and head axis, which may occur due to inaccuracy in the manufacture of parts and when the engine's thermal conditions change.
Наиболее близким техническим решением к предлагаемому вл етс цилиндр двигател внутреннего сгорани в котором повышение надежности уплотнени 1азового стыка достигаетс путем предельного уменьшени поверхности контакта между детал ми газового стыка. При этом торцу гильзы, примыкающему к уплотнительному кольц придана форма узкой кольцевой кромки с малым радиусом скруглени 2 .The closest technical solution to the present invention is an internal combustion engine cylinder in which an increase in reliability of the sealing of a 1-phase joint is achieved by limiting the reduction of the contact surface between the parts of the gas joint. At the same time, the end face of the liner adjacent to the sealing ring is shaped as a narrow annular edge with a small rounding radius 2.
Недостаток указанного цилиндра заключаетс в том, что в нем неThe disadvantage of this cylinder is that it does not
устран етс относительное угловое смещение осей гильзы и ру.башки цилиндра .eliminates the relative angular displacement of the axes of the liner and the cylinders of the cylinder.
Цель изобретени - повышение надежности уплотнени газового стыка путем устранени относительного углового смещени осей гильзы и рубашки цилиндра.The purpose of the invention is to increase the reliability of sealing the gas joint by eliminating the relative angular displacement of the liner axes and the cylinder liner.
Указанна цель достигаетс тем, This goal is achieved by
0 что опорные поверхности по са рубашки и уплотнительного кольца выполнены коническими, а примыкающие к ним соответствующие поверхности упорного бурта и торца гильзы - сферичес5 кими, причем центры сферических поверхностей расположены на оси цилиндра и смещены один относителоно другого.That the bearing surfaces of the jacket and the sealing ring are made conical, and the adjacent surfaces of the thrust collar and the end of the sleeve adjacent to them are spherical, with the centers of the spherical surfaces located on the axis of the cylinder and displaced relative to the other.
На чертеже изображен цилиндр, про0 дольный разрез.The drawing shows a cylinder, a longitudinal section.
Цилиндр имеет рубашку 1 с опорным по сом 2, имеющим коническую поверхность 3 и гильзу 4 цилиндра со сферическим торцом 5 и упорным бур5 том 6 со сферической поверхностью 7. Сферический торец 5 гильзы 4 цилиндра примыкает к уплотнительному кольцу 8 газового стыка, установленному в канавке 9 головки 10 Цилиндра и имеющему конический торец 11.The cylinder has a jacket 1 with a support catfish 2 having a conical surface 3 and a cylinder liner 4 with a spherical end 5 and a thrust drill 6 with a spherical surface 7. The spherical end 5 of the cylinder liner 4 is adjacent to a gas joint 8 in the groove 9 heads of 10 cylinder and having a conical end 11.
