Abstract
A split combined type wind cooling diesel engine cylinder liner comprises a cylinder liner body, an engine body positioning ring, a plurality of plate type radiating fins and a plurality of radiating cushions, wherein the plate type radiating fins and the radiating cushions are sleeved and mounted on the external periphery of the cylinder liner body at intervals, and screw bolt mounting holes are arranged on the plate type radiating fins. Due to the fact that the prior integral type monometallic cylinder liner is changed into a split combined structure, apart from that the cylinder liner retains the combination property requirements of the prior cylinder liner, the thicknesses of the plate type radiating fins and the radiating cushions are optional, not only the cylinder liner of this structure is provided with more excellent radiating performance, but also when bore of the cylinder liner body is abraded to be damaged, as long as the cylinder liner body is changed, all the engine body positioning ring, the plate type radiating fins and the radiating cushions can be used repeatedly, thereby guaranteeing the diesel engine cylinder liner is provided with due mechanical property and improving the radiating performance as well, and most of the parts can be used repeatedly.
Description
Technical field:
The utility model relates to a kind of one-cylinder diesel machine part, relates in particular to the cylinder liner of single-cylinder air-cooled diesel engine.
Background technique:
Existing single-cylinder air-cooled diesel engine cylinder liner majority is the monometallic cast iron cylinder cover, this monometallic cast iron cylinder cover one end links to each other with cylinder head, the other end is fixed tightly on the body by stay bolt, gas mixture constantly is compressed blast in cylinder liner when diesel engine is worked, therefore the operating temperature of cylinder liner is very high, must cool off it, otherwise diesel engine just can't proper functioning, because the two ends of cylinder liner are necessary and cylinder head, body connects, therefore on both ends of the surface, must offer bolt mounting holes, occupy bigger heat-dissipating space, because the radiating fin that is provided with on the monometallic cast iron cylinder cover outer wall is difficult to do very thinly, the efficiently radiates heat area of entire cylinder cover is difficult to increase like this, and heat dispersion is subjected to very big influence, causes cylinder liner to reduce working life, on the other hand, in case when the endoporus of cylinder liner may wear to the limit, whole part was all scrapped, can't reuse.
The model utility content:
Goal of the invention of the present utility model is to provide a kind of separate assembling air-cooled diesel engine cylinder liner, and it can overcome the problems referred to above that existing single-cylinder air-cooled diesel engine cylinder liner exists better.
The technical solution adopted in the utility model is as follows:
Separate assembling air-cooled diesel engine cylinder liner described in the utility model, comprise cylinder sleeve body 1, body positioning ring 2, some board-like radiating fin 3 and some cooling pads 4, one end of cylinder sleeve body 1 is provided with the seam boss 5 that links to each other with cylinder head, the other end of cylinder sleeve body 1 is provided with the shaft shoulder 6 that links to each other with body, board-like radiating fin 3 and cooling pad 4 are sleeved on the excircle of cylinder sleeve body 1 spaced reciprocally, body positioning ring 2 is sleeved on the shaft shoulder 6 of cylinder sleeve body 1 in the transition fit mode, on board-like radiating fin 3, be provided with bolt mounting holes 7, the external diameter of cooling pad 4 is less than bolt mounting holes 7 inner side surface place diameters, and all board-like radiating fin 3 and cooling pad 4 all place between seam boss 5 and the body positioning ring 2.
Described cylinder sleeve body 1 is the boron titanium cast iron, and the material of described board-like radiating fin 3 and cooling pad 4 is metal aluminum or aluminum alloy or steel plate, and its thickness is 0.5～3.0mm.
Described board-like radiating fin 3 is two composite structures of symmetry.
Because will have all-in-one-piece monometallic cylinder liner now makes into by cylinder sleeve body 1, body positioning ring 2, board-like radiating fin 3, the split composite structure that cooling pad 4 is formed, cylinder sleeve body 1 keeps the heat-resisting of existing cylinder liner, wear-resistant, high-intensity performance, the thickness of board-like radiating fin 3 and cooling pad 4 can be chosen arbitrarily, this cylinder liner not only has excellent more heat dispersion, when the internal diameter wearing and tearing of cylinder sleeve body 1 reach capacity, as long as change cylinder sleeve body 1, and body positioning ring 2, all board-like radiating fin 3 and cooling pad 4 are all reusable, both guaranteed that cylinder jacket of diesel engine should have mechanical property, improved the heat dispersion of cylinder liner again, most of part in the cylinder liner of scrapping can be reused, thereby make the environmental protection and energy saving material-saving characteristics that the utlity model has.
Description of drawings:
Fig. 1 is an example structure schematic representation of the present utility model.
Fig. 2 is the structural representation of whole board-like radiating fin 3.
Fig. 3 is the structural representation of split type board-like radiating fin 3.
Among the figure: 1-cylinder sleeve body; 2-body positioning ring; The board-like radiating fin of 3-; The 4-cooling pad; 5-seam boss; The 6-shaft shoulder; The 7-bolt mounting holes.
Embodiment:
Cylinder liner with 170F type single-cylinder air-cooled diesel engine is an example below, and in conjunction with Figure of description 1～3, embodiment of the present utility model is explained in detail:
A kind of cylinder liner of single-cylinder air-cooled diesel engine, it is by cylinder sleeve body 1, body positioning ring 2, some board-like radiating fin 3 and some cooling pads 4 are formed, the internal diameter of cylinder sleeve body 1 is 70mm, its upper end is provided with the seam boss 5 that links to each other with cylinder head, the external diameter of seam boss 5 is 92mm, intermediate section is the construction section of board-like radiating fin 3 and some cooling pads 4, its external diameter is 82mm, next end of cylinder sleeve body 1 is provided with the shaft shoulder 6 that links to each other with body, its external diameter is 78mm, board-like radiating fin 3 and cooling pad 4 are sleeved on the excircle of cylinder sleeve body 1 spaced reciprocally, and the internal diameter of board-like radiating fin 3 and cooling pad 4 cooperates with the crest clearance of cylinder sleeve body 1, be provided with four bolt mounting holes 7 on board-like radiating fin 3, all bolt mounting holes 7 are distributed on the circumference of 108mm, and the external diameter of cooling pad 4 is 92mm, the diameter of bolt mounting holes 7 is 16mm, the internal diameter of body positioning ring 2 is 78mm, and external diameter is 92mm, the shaft shoulder 6 transition fit of it and cylinder sleeve body 1.
Structure of the present utility model is equally applicable to the cylinder liner product of single cylinder or multi-cylinder air-cooled diesel engine or gas and oil machine.
