Description

Engine timing gear chamber cap assembly parts

Technical field

The utility model relates to engine technology, particularly timing gear for diesel engine chamber sealing configuration.

Background technique

The engine timing gear chamber cap is the seal arrangement of engine timing gear chamber, also is the engine crankshaft assembling connecting piece.General timing-gear chamber cover is to make blank by cast iron or aluminum alloy material through conventional cast or pressure casting process, is made through machining again.Also to be equipped with an advancing device case in addition during assembling, the advancing device case of prior art and the assembly structure of timing-gear chamber cover as shown in Figure 1, the general fastening pieces that adopt of advancing device case 2 are fixed on the timing-gear chamber cover 1.The shortcoming of this technology is: 1, conventional cast or pressure casting process energy consumption are big; 2, to pass through manufacture method complex procedures, the manufacturing efficiency of machining lower for conventional cast or high pressure die casting; 3, aluminum alloy material cost height; 4, equipment precision requirement height in the mechanical processing process requires height, time cost height to the manufacturing operation peopleware; 5, twice assembly cost height, efficient are low.

The model utility content

Technical problem to be solved in the utility model is exactly the above-mentioned shortcoming at prior art, and the assembly parts of a kind of advancing device case and engine timing gear chamber cap is provided.

The utility model solve the technical problem, and the technological scheme of employing is that engine timing gear chamber cap assembly parts comprises timing-gear chamber cover and advancing device case, it is characterized in that described timing-gear chamber cover and the as a whole parts of advancing device case;

Further, described engine timing gear chamber cap oil sealing mounting point is provided with reinforced structure;

Concrete, described reinforced structure is made of the stiffening rib that the oil sealing installed position becomes aplysia punctata to distribute;

More specifically, described stiffening rib is totally 4;

Preferably, described engine timing gear chamber cap assembly parts is a stamping part;

Preferably, described stamping part is a 1.5mm cold-rolling steel-plate punch spare.

The beneficial effects of the utility model are that the employing integral structure has been simplified production process, has strengthened the integrity of product structure, has improved manufacturing efficient, efficiency of assembling.Further adopt the cold-rolling steel-plate punch moulding, effectively reduce cost of material, manufacture cost and the assembly cost of product, and suitable mass production.

Embodiment

Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.

Engine timing gear chamber cap assembly parts of the present utility model has been integrated advancing device case and timing-gear chamber cover, adopt the stamping process once-through, above-mentioned two parts are made an one-piece element, simplified production process, strengthen the integrity of structure, improved manufacturing efficient and efficiency of assembling.

Embodiment

Engine timing gear chamber cap assembling unit structure of the present utility model as shown in Figure 2, the as a whole parts of this assembly parts, its structure has comprised timing-gear chamber cover 1 and advancing device case 2.For dissimilar motors, the shape of timing-gear chamber cover 1 and shape shown in Figure 2 may be different, but its structural difference is little.This routine engine timing gear chamber cap assembly parts, adopt the 1.5mm cold rolled sheet through the stamping process once-through, in order to increase the structural strength of assembly parts, the structural strength of oil sealing mounting point 10 particularly, this example has designed 4 stiffening ribs at 10 places, timing-gear chamber cover 1 oil sealing mounting point, increase the strength structure at this place, these 4 stiffening ribs become aplysia punctata to distribute along seal mounting hole.Fig. 3 illustrates the partial sectional view of advancing device case 2 place parts among Fig. 2, the overall structure effect of the engine timing gear chamber cap assembly parts that this is routine clearly has been described, the position of advancing device case 2 promptly is installed on timing-gear chamber cover 1 originally, stamp out a peviform projection, replace and need the advancing device case of assembling separately originally.
