Abstract
The utility model relates to a combustion engine mainly for JC85-JC90 single-cylinder diesel engines. The utility model is characterized in that: the sides of the flywheels employ a structural framework of dabbers and tangential dabbers to connect with each axle pores on the body in order to effectively increase the hardness of the sides, the side of the gear chamber cap is deprived of all dabbers and the gear chamber baffle is attenuated to balance the hardness of the two sides of the body and reduce the occurs of the distortion and the stress concentration. Thereby the utility model decreased the mass of the engine on the premise of guarantying the strength of structure. Besides, the utility model changes the structure of the head of the engine by employing a toric structure and stepwise arc chutes to strengthen the head hardness, increase the section of the cooling water channel, and improve the cooling effect. The utility model has distinctive economic benefits and is also widely applicable to other series single-cylinder diesel engines.
Description
Technical field
The utility model relates to field of internal combustion engine, refers in particular to a kind of body of single cylinder diesel, is mainly used in the JC85～JC90 serial diesel engine that has uniaxiality balance mechanism.
Background technique
JC85～JC90 serial diesel engine is the following maximum single-cylinder farm diesel engine of use of present domestic 8.8kW, along with diesel engine is constantly strengthened, the reliability of body worse and worse, usually be where to go wrong just to strengthen structure where, consequently not only increased the quality and the manufacture cost of body, wasted raw material, also can make body rigidity everywhere inhomogeneous, regional area produces the serious stress concentration phenomenon, directly has influence on strength of machine body.Former in addition body head design is unreasonable, and cooling water circulation cross section is too little, is unfavorable for the cooling of diesel engine, causes engine overheat easily, especially works as cylinder diameter and expands to after 90mm or the 95mm, and this phenomenon is even more serious.
Summary of the invention
The purpose of this utility model provides a kind of body of single cylinder diesel, this body adopts the various tangential bracings of local frame structure stiffening rib and reasonable Arrangement, improve the force-bearing situation of body, reduce the body rigidity of gear chamber side, increase the body rigidity of flywheel side, the structural rigidity of body each several part is reached unanimity, under the prerequisite that reduces the dangerouse cross-section place of body stress, alleviate the body quality.Change the body head construction in addition, increased cooling water circulation cross section, improved cooling effect, increased the rigidity of body head simultaneously, alleviated the quality of head.
Concrete technological scheme is: the stiffening rib that frame-shaped structure is set with rear side above body flywheel side; Tangent direction along the main bearing seat circumference is provided with tangential bracing, increases the radial thickness of main bearing seat; The body head adopts multi-face structure, uses girt substitution level stiffening rib up, below replace former machine dividing plate with cascade circular arc dividing plate, not only strengthened head rigidity, alleviate quality, also increase the cooling-water flow cross section, improved cooling effect; Medial and lateral at the cylinder head bolt position are provided with horizontal stiffener, are connected with crankcase, strengthen the rigidity of flywheel side; In the gear chamber cover side of body, eliminate all stiffening ribs, the horizontal stiffener at a retained gas cylinder bolt position, reduce the radial thickness of each bearing support, and attenuate gear chamber block board thickness, reduce the rigidity of body gear chamber cover side, thereby the rigidity of body both sides is reached unanimity.
After the utility model has the advantages that the employing such scheme, the reliability of present body and the contradiction of quality have been solved.Because adopt local frame structure can improve the ability of body resistance type effectively, and tangential bracing can be delivered to gaseous-pressure the rear end and the stone bolt of body with path the most efficiently, gaseous-pressure can be directly delivered on each bearing hole simultaneously, prevent that bearing hole from producing distortion and stress concentration phenomenon, adopt said structure, can under the prerequisite that guarantees housing construction intensity, alleviate the body quality more than 1 kilogram.The utility model also can be widely used in other serial single cylinder diesel body, and economic benefit is very remarkable, and vast market prospect is arranged.
Description of drawings
Concrete structure of the present utility model is provided by the following drawings and example:
Fig. 1, Fig. 2, Fig. 3 are shaft side figure of the present utility model
Each bearing support 10 body head girts 11 cascade circular arc dividing plate of multi-face structure 6 cylinder liner lower support positions 7 flywheel side main bearing seats, 8 gear chamber dividing plates, 9 gear chamber cover sides of 1 body flywheel rear flank end frame structure stiffening rib, 2 body flywheel sides top frame structure stiffening rib 3 tangential bracings 4 cylinder head bolt medial and lateral horizontal stiffener 5 body heads
Embodiment
Now in conjunction with the accompanying drawings an embodiment's of the present utility model structure is described in detail: as Fig. 1, Fig. 2, shown in Figure 3: the utility model stiffening rib 1 of body flywheel rear flank end frame structure, the stiffening rib 2 of machine body top frame structure, tangential bracing 3, in the cylinder head bolt, outside horizontal stiffener 4 links together flywheel side main bearing seat 7, increase this side body rigidity, stiffening rib with the gear chamber cover side removes simultaneously, the thickness of attenuate gear chamber dividing plate 8, reduce the radial thickness of each bearing support 9 of gear chamber cover side, thereby reduce the rigidity of gear chamber cover side; The head of body adopts multi-face structure 5, and above-head adopts girt 10, and cascade circular arc dividing plate 11 is adopted in the below, strengthens body head rigidity, increases the cooling-water flow cross section, improves the engine cooling performance.
Present embodiment only is used to illustrate the utility model, and does not limit.
