The single cylinder diesel body
Technical field
The utility model relates to a kind of diesel-engine body, particularly a kind of single cylinder diesel body.
Background technique
The part of diesel engines carries out high-speed motion each other relatively, if there is not lubricant oil between them, the meeting enhance faster wear also produces a large amount of heats, existing a kind of single cylinder diesel body, as shown in Figure 4, have tank filler sleeve and crankshaft lubrication oilhole, the crankshaft lubrication oilhole is used for lubricated bent axle, the crankshaft lubrication oilhole is a horizontal through hole, one end is positioned at the gear chamber capping of single cylinder diesel, the other end is positioned at diesel-engine body, and its tank filler sleeve is arranged on the last end face sidepiece of diesel-engine body, makes a call to a penetration hole and connect crankshaft lubrication oilhole and tank filler sleeve on last end face.Owing to be easy to generate the phenomenon that oilhole ftractures after the stress on the upper top cover originally just greatly, is processed tank filler sleeve and penetration hole in the above.
Summary of the invention
The purpose of this utility model is to provide a kind of housing construction more firm, rational single cylinder diesel body, reduces the phenomenon of other position crackings of oilhole and body.
The technological scheme that its purpose that realizes the utility model adopts is: a kind of single cylinder diesel body, has gear chamber, at gear chamber outer wall end face a tank filler sleeve is set, has an inside horizontally disposed crankshaft lubrication oilhole on the gear chamber capping, tank filler sleeve is communicated with the crankshaft lubrication oilhole.
Also have a boss at gear chamber outer wall end face, tank filler sleeve is arranged on the boss and is communicated with the crankshaft lubrication oilhole.
Also have cylinder sleeve water cavity and cylinder head screw on the body, arrange in the symmetrical position of two side cylinder head screws and expose muscle, the cylinder sleeve water cavity is a circular arc camber.
The beneficial effects of the utility model are: tank filler sleeve is arranged on the outer wall of gear chamber, has avoided end face boring on body, increased body intensity, avoided the generation of tank filler sleeve cracking phenomena simultaneously.The design that exposes muscle guarantees that the moment that produces when the cylinder head bolt in the cylinder head screw is tightened can not make cylinder cap face, cylinder head screw, cylinder head screw bottom deform or ruptures; The jacket water cavity outer wall is designed to circular arc camber, and it is long-pending to have increased body water cavity active cooling surface, connects the muscle that exposes of cylinder head screw two sides simultaneously with the curved surface principle, has strengthened the rigidity and the intensity of body.

Embodiment
As Fig. 1,2,3 one kind of single cylinder diesel body, have gear chamber 1, cylinder sleeve water cavity 2, cylinder head screw 3, has a boss 6 at gear chamber 1 outer wall end face, oil inlet hole 4 is arranged on the boss 6, on gear chamber 1 capping, has an inside horizontally disposed crankshaft lubrication oilhole 5, crankshaft lubrication oilhole 5 feeds internal body, and tank filler sleeve 4 is communicated with crankshaft lubrication oilhole 5.
Crankshaft lubrication oilhole 5 is installed lubricating oil pressure gauge at an end of gear chamber 1 capping, and lubricant oil enters crankshaft lubrication oilhole 5 from tank filler sleeve 4 and is used for lubricated bent axle.Symmetrical position layout at two side cylinder head screws 3 exposes muscle 7, and cylinder sleeve water cavity 2 is a circular arc camber, as shown in Figure 5.
