Abstract
The utility model discloses a light-weight equal-rigidity aluminum diesel engine body, which relates to the field of internal-combustion engine body manufacture and is mainly used for a single-cylinder air cooling diesel engine with the air cylinder diameter being 65 to 80mm. The front side and the back side of the light-weight equal-rigidity aluminum diesel engine body are connected into a framework structure through two tappet post seats, the framework structure is provided with reinforcing ribs, integral convex blocks, heat radiation ribs, arch-shaped composite curve surface structures and lug bosses are in inclined arrangement, and the oil spray pump flange surface is connected into a whole with the front end surface of the engine body, so the engine body approaches to the equal-rigidity design, and under the work load, all major bearing holes, air cylinder installing holes, oil pump installing holes and the concentricity, the cylindricity and the planeness of a gear chamber cover end surface are positioned at the same horizontal plane as the cast iron engine body. The maximum succession with the original machine in aspects of the structure and the manufacture process is realized, the installation of other components is not influenced, the mass production can be organized through the original mechanical processing line, and the requirements of different users can be met.
Description
Technical field
The utility model relates to internal combustion (IC) engine airframe and makes the field, is mainly used in the single-cylinder air-cooled diesel engine of cylinder bore 65-80mm.
Background technique
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, the quality and the manufacture cost of body have consequently not only been increased, raw material have been wasted, also can make body rigidity everywhere inhomogeneous, regional area produces the serious stress concentration phenomenon, directly has influence on strength of machine body.Along with the raw material resources exhaustion, price constantly rises violently in addition, has proposed the requirement of energy-saving material-saving.
At present, domestic single-cylinder air-cooled diesel engine body uses the gray cast iron manufacturing, and the body quality lays particular stress on.The body of external similar type uses the aluminum alloy manufacturing, compares with it, and specific mass is low, power per liter is low, can not adapt to the requirement of low energy consumption, energy-conserving product.
Summary of the invention
The purpose of this utility model is to adopt the aluminum alloy low-pressure casting body, compares with cast iron engine block, and quality alleviates 58%, but that maximum problem is the Young's modulus of cast aluminium is little, and hardness is low, so the amount of deformation of body increases, and makes the motor cisco unity malfunction when serious.Characteristics of the present utility model are the reasonable Arrangement by housing construction and stiffening rib, rigidity Design such as be tending towards, promptly under work loads, coaxality, cylindricity, planeness and the cast iron engine block of each main bearing hole, cylinder mounting holes, oil pump mounting hole, gear chamber cover end face are in same level.
Technical solution adopted in the utility model is that gear chamber terminal body leading flank, the flywheel side body trailing flank of two tappet seats and body both sides fuse, and form frame structure; At four stiffening ribs of flywheel side body trailing flank cavity arrangements, described four stiffening ribs are for being in tilted layout, directly guide cylinder head bolt power into body base stone bolt boss by bearing support and stiffening rib, reinforce with four stiffening ribs at base plate and body trailing flank simultaneously; The bottom of body front-end face, body rear end face is adopted the tilting whole projection of tilting front-end face, the tilting whole projection intensive aspect base stone bolt boss of ear end face respectively; Outwards protrude flywheel side body trailing flank bottom, and arrange radiating fin in the outside; Step arch compound curved surface structure is adopted at the top of body; Reinforce with gear chamber periphery boss and gear chamber periphery stiffening rib around the gear chamber, simultaneously Injection Pump installation base and body front-end face are fused.
The beneficial effects of the utility model are, structurally with on the manufacturing process maximum inheritance is arranged, do not influence the installation of other component, can organize production in enormous quantities with original machine line with former machine, can satisfy the requirement of different user, its economic benefit and social benefit are good.

Embodiment
Now in conjunction with the accompanying drawings structure is described in detail.
The utility model fuses two tappet seats 1 at the inner chamber of body with body both sides gear chamber terminal body leading flank 2, flywheel side body trailing flank 3, form frame structure, be divided into the body front end two-layer, can strengthen the integral rigidity of body significantly, reduce cylinder block mounting hole and bearing hole distortion; The bearing hole of flywheel side body trailing flank 3 is bigger, its rigidity is relatively poor, therefore at body cavity arrangements body trailing flank inner chamber stiffening rib 4, directly guide cylinder head bolt power into body base stone bolt boss 5 by bearing support and stiffening rib, reinforce at base plate and four body bottom surfaces of flywheel side body trailing flank 3 usefulness stiffening rib 6 simultaneously; The tilting whole projection 9 of front-end face, the tilting whole projection 10 of ear end face are adopted in the bottom of body front-end face 7, body rear end face 8, strengthen the rigidity of body base, outwards protrude flywheel side body trailing flank 3 bottoms simultaneously, and behind the placement machine body of the outside side lower part radiating fin 11, can increase 15% left and right sides lubricant oil memory space, simultaneously lubricant oil is dispelled the heat effectively, strengthen the rigidity of organism soleplate.Step arch compound curved surface structure 12 is adopted at the top of body, has strengthened the rigidity of body upper effectively.Gear chamber 13 is hatch frames, rigidity is relatively poor, for preventing gear chamber end face torsional deformation, oil leakage phenomenon occurs, around gear chamber, utilize gear chamber periphery boss 14 and gear chamber periphery stiffening rib 15 to reinforce, simultaneously Injection Pump installation base 16 and body front-end face 7 are fused.
