Abstract
The utility model relates to a separate cylinder sleeve connecting structure, which mainly fastens a separate cylinder sleeve on an independent machine body by a cylinder cover stud. A separate cylinder sleeve gasket is lined on the surface, combined with the independent machine body, of the lower part of the separate cylinder sleeve. A cylinder cover gasket is lined on the surface, connected with a cylinder cover, of the upper part of the separate cylinder sleeve. The lower part of the separate cylinder sleeve is partially extended into the independent machine body. One end of the cylinder cover stud is locked on the independent machine body, and the other end of the cylinder cover stud is fastened on the cylinder cover by a cylinder stud gasket and a fastening nut. The separate cylinder sleeve connecting structure ensures casting and processing properties, greatly reduces the rejection rate of parts to the minimum to improve the economic benefits, simultaneously makes the independently-machined separate cylinder sleeve simple and convenient to rearrange, and solves a series of problems of air leakage, burning through of a cylinder gasket, the aggravated abrasion of an inner hole and a piston ring of the cylinder sleeve, even oil burning and the like caused by the deformation of the cylinder sleeve.
Description
Technical field
The utility model relates to the linkage structure device of a kind of air cooling engine cylinder liner and body, specifically is used for the structural type that is linked and packed of air cooling engine cylinder liner and body, belongs to field of power equipment technology.
Background technique
In traditional air cooling engine structure, cylinder liner and body are cast into one, and promptly tradition all is that cylinder liner is embedded on the body; Promptly two kinds of different materials are embedded in together, cast and to add the man-hour adjustable poor, and the learies of cylinder body is big, and is less economical.From process aspect, cylinder liner and body cast in a time-out complex process, when serious even generations of breaking arranged, casting processing are already also had higher requirement.Cylinder bolt directly is locked on the cylinder liner simultaneously, after the cylinder bolt locking, under the effect of power, can cause the distortion of cylinder liner junction plane, cause easily that gas leakage, head gasket are easily burnt, the distortion of cylinder liner also can cause endoporus, the generation of a series of problems such as wear of piston-rings aggravation even burn oil.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of separated type cylinder liner linkage structure, this linkage structure can be improved the manufacturability of casting, processing, the scrappage of part is reduced to bottom line greatly, requirement to the casting processing industry also reduces greatly, thereby has improved economic benefit.
According to the technological scheme that the utility model provides, a kind of separated type cylinder liner linkage structure comprises free-standing body, separated type cylinder liner, cylinder head; Described separated type cylinder liner is fastened on the free-standing body by the cylinder cap stud, described separated type cylinder liner bottom and free-standing body junction plane are lined with separated type cylinder liner pad, the junction surface of described separated type cylinder liner top and cylinder head is lined with cylinder head gasket, the bottom part of described separated type cylinder liner reaches in the free-standing body, end with the cylinder cap stud is locked on the free-standing body, and the other end is fastened on the cylinder head by cylinder head bolts pad, tightening nut.
Compared with the prior art the utility model has the following advantages:
The utility model has guaranteed the manufacturability of casting, processing, and the scrappage of part is reduced to bottom line greatly, the requirement of casting processing industry is also just reduced greatly, thereby improved economic benefit.It is also simple, convenient when the separated type cylinder liner that processes is separately simultaneously installed again; The gas leakage that the distortion of cylinder liner causes, burn head gasket, cylinder cover inner hole and a series of problems such as wear of piston-rings aggravation even burn oil also are resolved.
Description of drawings
Fig. 1 surveys schematic representation for the utility model separated type cylinder liner axis of no-feathering that is linked and packed.
Fig. 2 is the utility model separated type cylinder liner structural plan schematic representation that is linked and packed.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 2, comprise free-standing body 1, separated type cylinder liner pad 2, separated type cylinder liner 3, cylinder head gasket 4, cylinder head 5, cylinder cap stud 6, cylinder head bolts pad 7, tightening nut 8 etc.
The utility model embodiment's motor is an air cooling engine, is used for for example working machine etc.
The utility model separated type cylinder liner 3 linkage structures are locked in separated type cylinder liner 3 on the free-standing body 1 by cylinder cap stud 6, for preventing that leakage of oil, gas leakage separated type cylinder liner 3 bottoms and free-standing body 1 junction plane are lined with separated type cylinder liner pad 2, the junction surface of separated type cylinder liner 3 tops and cylinder head 5 is lined with cylinder head gasket 4.The bottom part of separated type cylinder liner 3 reaches free-standing body 1 the inside, directly is locked on the free-standing body 1 with an end of cylinder cap stud 6, and the other end by cylinder head bolts pad 7, tightening nut 8 with cylinder head 5 under lock and key.
The utility model separated type cylinder liner 3 linkage structures to the distortion of cylinder liner also can cause gas leakage, burn head gasket, cylinder cover inner hole and wear of piston-rings aggravation, even a series of problems such as burn oil also are resolved, and the manufacturability of processing requires also to reduce greatly simultaneously.
