Abstract
The utility model relates to a die-casting aluminium flywheel shell of diesel engine, including the flywheel shell body, the outer fringe connection face evenly distributed of flywheel shell body and gearbox has a plurality of heavy holes of going, and flywheel shell body excircle side is equipped with circular net strengthening rib, and the flywheel shell body back is equipped with scattering formula net strengthening rib and a plurality of ring strengthening rib. The utility model discloses weight reduction 50%, wall thickness attenuate 4mm, improved the pleasing to the eye of bell housing under the circumstances of subtracting heavy, reduced the weight of engine self.
Description
Technical Field
The utility model relates to a flywheel shell, in particular to diesel engine die-casting aluminium flywheel shell.
Background
The flywheel shell material that most of present diesel engines use is cast iron, the wall is thick, cause the circulation is not good while casting, will form "sand hole"; the volume is large, the weight is large, and the self weight of the engine is increased; high processing cost, rough casting surface and unattractive appearance.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a diesel engine die casting aluminium flywheel shell. Under the condition of weight reduction, the appearance of the flywheel housing is improved, and the weight of the engine is reduced.
The utility model discloses there is following technical scheme to realize:
the utility model provides a diesel engine die-casting aluminium flywheel shell, includes the flywheel shell body, and flywheel shell body connects the face evenly distributed with the outer fringe of gearbox and has a plurality of heavy holes that go, and flywheel shell body excircle side is equipped with circular net strengthening rib, and the flywheel shell body back is equipped with scattering formula net strengthening rib and a plurality of ring strengthening rib.
Furthermore, the scattering grid reinforcing ribs and the plurality of circular ring reinforcing ribs are mutually staggered to form a grid shape.
Furthermore, the thickness of the flywheel casing is about 6mm, and the weight is about 9.4 kg.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses a flywheel casing adopts the die-casting aluminium material, and the flywheel casing openly is connected the design theory that adopts the heavy hole with the gearbox, and the flywheel casing excircle increases circular net strengthening rib, and the flywheel casing back adopts scattering formula net strengthening rib for holistic weight reduction 50%, wall thickness attenuate 4mm has improved the pleasing to the eye of flywheel casing under the circumstances of subtracting heavy, has reduced the weight of engine self.
Drawings
Fig. 1 is a schematic front structural view of the present invention;
fig. 2 is a schematic side view of the present invention;
fig. 3 is a schematic diagram of the back structure of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some examples of the present invention, not all examples. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in figure 1, the die-casting aluminum flywheel casing of the diesel engine comprises a flywheel casing body, wherein a plurality of strip-shaped holes 1 are uniformly distributed on the outer edge connecting surface of the flywheel casing body and a transmission case, and part of weight can be reduced.
As shown in fig. 1 and 2, the outer side surface of the flywheel housing body is provided with a circular grid reinforcing rib 2, and the back surface of the flywheel housing body is provided with a scattering grid reinforcing rib and a plurality of circular ring reinforcing ribs. The scattering grid reinforcing ribs and the plurality of circular ring reinforcing ribs are mutually staggered to form a grid shape, as shown in fig. 3.
The outer circle at the front end of the flywheel shell adopts a dead weight removing mode, so that the weight can be reduced, the reinforcing rib can be played, the strength is increased, and the sand hole formed due to the over-thick wall thickness in the die casting process can be reduced.
The mode of circular net strengthening rib is adopted around the bell housing excircle, increases excircle intensity to increase the strengthening rib in the position department of installation bolt hole. The back of the flywheel shell adopts scattering grid reinforcing ribs to enhance the longitudinal and transverse tension of the flywheel shell and enhance the strength of the flywheel shell under the condition of weight reduction. The utility model discloses the heavy problem of bell housing has been solved to the bell housing, and the cast iron bell housing of comparing has increased intensity through the structural mode that adds the strengthening rib, and weight reduction 50%, wall thickness attenuate 4mm, and reduce cost has beautified the outward appearance.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
