Abstract
The utility model relates to the improvement of a flywheel casing of a cover cap of a multi-cylinder diesel engine gear chamber. The utility model is characterized in that the inclination of the flywheel casing axially extending a surface is small and is from 1 DEG to 2.5 DEG, stiffening ribs are arranged on connecting blocks of the flywheel casing and a base and among the connecting blocks, and a drop pit is arranged on the inner side wall of a flywheel cavity at the middle part of the skirt edge of the flywheel casing. The weight of the flywheel casing is lightened, mechanical performance is greatly increased, and the utility model is suitable for high powered diesel engines.
Description
Utility model is about the improvement to multi-cylinder diesel engine gear chamber cover cap clutch bell.
Existing multi-cylinder diesel engine gear chamber cover cap clutch bell (as a vapour multi-cylinder diesel engine gear chamber cover cap clutch bell) is because special-shaped complexity adopts aluminum alloy low-pressure casting process and gravity foundry technology mold casting forming usually.For adapting to above-mentioned mold casting forming technology, product structure is unreasonable, also do thicklyer as the wall thickness that need not thicken position (for example inboard, flywheel chamber, middle part, shirt rim), like this because above-mentioned foundry technique crystallization pressure is low, full pressure is not enough, cause the feeding deficiency, defective such as that the die casting finished product can produce at this position is loose, shrinkage cavity, insufficient strength; Secondly for making things convenient for the demoulding after the die casting, the surperficial gradient of the axial sponson of clutch bell reaches 3.5 degree more greatly, and not only waste material increases product weight, and causes defectives such as producing loose, shrinkage cavity because of wall unevenness is even easily; Besides on the clutch bell with the contiguous block insufficient strength of base, ruptures easily in the installation back.These not only influence the mechanical performance index such as intensity, stretch ratio of clutch bell, and product materials is many, and weight is big, and the die casting yield rate is low, and manufacturing cost is higher relatively.More can not satisfy the requirement of high-power diesel engine to clutch bell, thereby present high-power multi-cylinder diesel engine can only adopt the cast iron clutch bell, diesel engine power and weight ratio index are low, and have increased clutch bell mechanical processing difficulty and machining cost.
The purpose of utility model is the improvement of doing at the defective of above-mentioned clutch bell existence, provides a kind of rational in infrastructure, and materials are economized, and are in light weight, intensity height, the multi-cylinder diesel engine gear chamber cover cap clutch bell of good mechanical property.
The utility model purpose realizes, mainly improves that to be that surperficial gradient with the axial extension of clutch bell changes little, becomes the 1-2.5 degree, not only can reduce material consumption, reduces manufacturing cost, but also can alleviate clutch bell weight, improves intensity.Specifically, utility model multi-cylinder diesel engine gear chamber cover cap clutch bell is characterized in that it is the 1-2.5 degree that said clutch bell axially stretches out surperficial gradient.The utility model clutch bell axially stretches out surperficial gradient, can equate, can not wait yet, wherein less with the gradient of patrix flywheel chamber medial surface and shirt rim lateral surface especially is the 1-2 degree, counterdie clutch bell fixed connecting part side shaft in stretching out lateral surface and gear cavity then the gradient of face slightly greatly the 1.5-2.5 degree for well, by upper and lower mould molding gradient difference, difference is held power tightly about forming, and helps shaped article and deviates from patrix like this.
Utility model also product has pit on the flywheel chamber madial wall of clutch bell shirt rim middle part (the speed measuring device position is installed), not only can reduce the product material consumption, and can solve thoroughly that this position is loose, shrinkage cavity defect, strengthens the mechanical characteristics at this position.
For improving on the clutch bell intensity with the base contiguous block, utility model has the reinforced rib of protrusion on contiguous block, can also the connection reinforced rib be set between two contiguous blocks, with the intensity of further raising contiguous block.
Below in conjunction with the description of an indefiniteness embodiment, further specify the utility model structure.
Fig. 1 is 6 cylinder diesel gear chamber cover cap clutch bell plan structure scheme drawings.
Fig. 2 is Figure 1A-A sectional structure scheme drawing.
Fig. 3 is that Fig. 2 B is to the bowl configurations partial schematic diagram.
Embodiment: referring to accompanying drawing, the gradient of flywheel chamber 2 medial surfaces 3 of diesel engine gear chamber cover cap clutch bell 1 and the lateral surface 5 of shirt rim 4 is smaller to be 1.5 degree, and the gradient of the interior then face 9 that axially stretches out lateral surface 7 and gear cavity 8 of clutch bell captive joint piece 6 one sides is 2 degree slightly greatly.Have pit 11 on the flywheel chamber madial wall at 4 middle parts, shirt rim (the speed measuring device position is installed) 10, the top degree of depth of pit 11 is greater than the bottom degree of depth.Be provided with between reinforced rib 12, two contiguous blocks of protrusion with the contiguous block 6 of base on the clutch bell and be provided with reinforced rib 13.
Utility model makes that not only wall thickness is even owing to reduced the surperficial gradient of clutch bell, improves the foundry technique performance of product, and alleviated product weight, but about same size product loss of weight 1KG.The setting of connecting portion reinforced rib has improved the intensity at this position greatly, has effectively avoided the phenomenon of rupture after the installation.The pit that flywheel chamber, shirt rim middle part madial wall is provided with not only can 100% have eliminated that this position is loose, the defective of shrinkage cavity, and also is favourable to expendable weight.The utility model clutch bell not only can be used for the diesel engine of general power, but also can be used for high-horsepower diesel engine, has improved diesel engine power and weight ratio index.
For convenience of description, the said multi-cylinder diesel engine gear chamber of utility model cover cap clutch bell and flywheel two speech indications are same thing.
