Description
Technical field
The utility model relates to the split type body sealing configuration of a kind of air-cooled diesel, belongs to air-cooled diesel engine body technique field.
Background technique
Diesel engine has all reached widely in all trades and professions as generating, power plant to be used.Diesel-engine body occupies extremely crucial position in parts and components of diesel engine, all work systems all are installed on the body, and the Rigidity and strength of body directly affects life-span, the sealing between each assembly and the distortion of component of component.Present air-cooled diesel engine mostly adopts split type body, former body is divided into independently body and cylinder barrel, and cylinder barrel is provided with cylinder sleeve, cylinder sleeve is installed in the sleeve port of body, by fastening piece body is connected with cylinder barrel, and the junction plane between body and the cylinder barrel is realized sealing by copper packing.Because the valve actuating push rod seat is arranged on jacket casing one side, therefore the valve actuating push rod seat is respectively the upper valve actuating push rod seat that is arranged on cylinder barrel and the lower valve ram seat that is positioned on the body, when cylinder barrel is connected with body, mainly be to connect with four cylinder sleeve bolts near cylinder barrel, cylinder barrel is positioned at the outside and is provided with two mounting holes, by two bolts cylinder barrel is installed on the body, because the cylinder sleeve on the cylinder barrel is directly installed in the body and by copper packing and seals, therefore on, lower valve ram seat junction plane also only can rely on the copper packing sealing, therefore on, lower valve ram seat peripheral sealing is affected by locking torque, cause seal herein unstable, so that sealability is relatively poor, very easily cause machine oil to reveal from its mating face in a large number, oil temperature is risen, thereby affect power and the clean appearance degree of diesel engine, also greatly increase Consumer's user cost.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, can effectively reduce the split type body sealing configuration of air-cooled diesel engine of oil leakage between the upper and lower valve actuating push rod seat mating face.
The utility model is that the technological scheme that achieves the above object is: the split type body sealing configuration of a kind of air-cooled diesel engine, comprise cylinder barrel and body, cylinder sleeve on the cylinder barrel is installed in the sleeve port of body, the upper valve actuating push rod seat that cylinder barrel is positioned at sleeve port one side is corresponding with the lower valve ram seat on the body, cylinder barrel is installed on the body by fastening piece, it is characterized in that: described body is provided with annular groove or/and cylinder barrel is provided with annular groove on the mating face of upper valve actuating push rod seat on the mating face of lower valve ram seat, seal ring is installed in the annular groove, and the copper packing and the seal ring that are arranged between cylinder barrel and the body junction plane join.
The lower valve ram seat mating face of the utility model body is or/and the upper cylinder pole socket mating face of cylinder barrel is provided with annular groove, so seal ring can be placed in the annular groove, when cylinder barrel is connected on the body by fastening piece, in the mating face sealing of copper packing to the mating face of body and cylinder barrel, copper packing is crimped on the seal ring, by seal ring further to upper, lower valve ram seat seals between the mating face reliably, under normal locking torque, keep, the stability of lower valve ram seat mating face sealing, and on improving, sealability between the lower valve ram seat mating face, solved the problem of valve actuating push rod seat mating face periphery lubricating oil leakage, minimizing has also reduced Consumer's user cost to the impact of diesel engine power.The utility model is on the basis that does not change the existing split type housing construction of air-cooled diesel engine, only by the seal ring that is arranged in the annular groove mating face between the upper and lower valve actuating push rod seat is sealed, rational in infrastructure, simple, be convenient to processing, install and maintenance.
