Abstract
The utility model relates to a diesel engine body, in particular to a double-cylinder air-cooled diesel engine body, comprising a base (1). Bottom studs (2) are symmetrically arranged at the lower parts of the left and right sides of the base (1); two location pinholes I (4) and a plurality of bolt holes (3) are arranged on the end surface of the base (1); the base (1) and the bottom studs (2) have an integral structure; a location pinhole II (6) is arranged below one of the two locating pinholes I (4); and the effective thread depth of the bolt hole (3) ranges from 16mm to 20mm. The double-cylinder air-cooled diesel engine body has the advantages that the strength is high, the locating effect is good, the installation is convenient, oil is not easy to leak, and the running stability of a diesel engine is good.
Description
Technical field
The utility model relates to a kind of diesel-engine body, specifically relates to a kind of double cylinder wind cooling diesel body.
Background technique
Body is the most key part of diesel engine, it also is the part of size and weight maximum, on structural design, to guarantee that body has enough rigidity and intensity on the one hand, also will guarantee housing construction connection and reasonable arrangement, compactness simultaneously, its reasonable in design directly influences power character, Economy, reliability and the emission performance index of diesel engine.Present double cylinder wind cooling diesel body, its pedestal and footing are split-type structural, interfix by bolt, and body intensity is relatively poor, and difficulty is installed, and the diesel engine operation stability is poor, shakes bigger; Be symmetrically set with two positioning pin holes on the pedestal end face, owing to be two point locations, its locating effect is relatively poor, and each bolt hole is dislocation up and down easily, and machine vibration is big after installing; End face upper bolt hole effective thread is shorter, and lock screw is fastening unreliable, easily causes the body leakage of oil.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the double cylinder wind cooling diesel body of a kind of intensity height, good positioning effect, easy for installation, not easy oil leakage and diesel engine good operation stability is provided.
The purpose of this utility model is achieved in that a kind of double cylinder wind cooling diesel body, it comprises pedestal, bottom, the pedestal left and right sides is symmetrically arranged with footing, and the pedestal end face is provided with two positioning pin hole I and several bolts hole, and be characterized in: described pedestal and footing are monolithic construction.
One of them below of described two positioning pin hole I also is provided with a location pin-and-hole II.
The effective thread degree of depth of described bolt hole is 16mm ~ 20mm.
Compared with prior art, the beneficial effects of the utility model are:
A kind of double cylinder wind cooling diesel body of the utility model, its pedestal and footing are monolithic construction, intensity is higher, easy for installation, the diesel engine operation stability is better, shake lessly, the pedestal end face is provided with three positioning pin holes and some bolts hole, and the effective thread degree of depth of bolt hole is 16mm ~ 20mm, therefore its locating effect is better, bolt hole is difficult for dislocation, can effectively increase the locking intensity of lock screw, is difficult for causing the body leakage of oil, the radiating fin of matrix cylinder liner outer surface is widened 5mm, increased heat diffusion area, radiating effect is better, can effectively reduce the oil temperature in the body.
Description of drawings
Fig. 1 is the structural representation of the utility model double cylinder wind cooling diesel body.
Wherein:
Pedestal 1, footing 2, bolt hole 3, positioning pin hole I4, radiating fin 5, positioning pin hole II6.
Embodiment
Referring to Fig. 1, the utility model relates to a kind of double cylinder wind cooling diesel body, it comprises pedestal 1, bottom, pedestal 1 left and right sides is symmetrically arranged with footing 2, pedestal 1 and footing 2 are monolithic construction, directly pass through casting, pedestal 1 end face is provided with two positioning pin hole I4 and several bolts hole 3, described two positioning pin hole I4 are symmetrical set, one of them positioning pin hole I4 below also is provided with a location pin-and-hole II6, the quantity suggestion of described bolt hole 3 is adopted 17, the effective thread degree of depth of bolt hole is 16mm ~ 20mm, and the cylinder liner outer surface on the pedestal 1 is provided with radiating fin 5, and the utility model is widened 5mm with radiating fin 5, to increase radiating effect, reduce oil temperature in the diesel engine.
