Abstract
The invention provides a crankcase oil tray for a ramjet propulsion, which is characterized in that a positioning protrusion is arranged on the upper surface of the crankcase oil tray combined with an engine frame; a sealing cushion is sleeved on the positioning protrusion by a positioning hole on a corresponding position; a purge cock seat is fixed on the position of an oil drain hole of the ramjet crankcase oil tray; and a purge cock is in threaded fit with the purge cock seat. The crankcase oil tray can ensure reliable positioning of a rubber ring, decrement of a rubber gasket, and reliable sealability of the position placing the purge cock.
Description
Technical field
The present invention relates to engine sump tank, the stamping type engine oil sump of more specifically saying so.
Background technique
Engine sump tank is to store machine oil and machine oil is provided for lubrication system, and oil sump and framework constitute crankcase jointly.Mainly contain punching press and casting dual mode at present.The casting oil sump is because quality is heavy, and price is also comparatively expensive.The punching oil drain pan is because of light weight, and cost is low relatively, and the punching oil drain pan has more widely to be used.
In the prior art, between the oil sump of motor and engine body, be the purpose that reaches sealing by the form that is coated with one deck sealer or rubber sheet gasket basically.This wherein, the application of coating technique is fewer and feweri, on the one hand gluing control is bad, glue-line is when being squeezed, be easy to cause the obstruction of bolt hole or framework spill port, when motor can not get oil return timely, even can cause the risk that crank shaft oil seal is rushed out.On the other hand, when motor was reprocessed or changed oil sump, the sealing on framework or the oil sump must be removed, and removing work is wasted time and energy, and befouling environment.Therefore, more employings is the form of gasket seal.Adopt the decrement of the necessary strict control rubber sheet gasket of gasket seal, so just make production be not easy control.
For the punching oil drain pan, its wall thickness is very thin, and the purge cock sealing is bad, after long-time the use, sliding dental phenomenon can take place.
In order to limit rocking of lubricant oil, reduce the machine oil air content, a dividing plate is set in the prior art, but dividing plate and oil sump are split settings, therefore have the process of assembling in oil sump.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology deficiency, a kind of stamping type engine oil sump is provided, to guarantee the reliable location of rubber ring, guaranteeing the decrement of rubber sheet gasket, and can effectively avoid the reliable sealing performance at purge cock place.
Technical solution problem of the present invention adopts following technological scheme:
The present invention adopts the punching oil drain pan.
The structural feature of punching oil drain pan of the present invention is:
Oil sump upper surface combining with engine frame is provided with locator protrusions, and seal rubber pad is sleeved on the locator protrusions with the positioning hole on the corresponding position;
On the drain oil position of described punching oil drain pan, fixedly install the purge cock seat, screw-thread fit between purge cock and the purge cock seat.
It is integral structure that oil sump internal partition and oil sump are set.
Oil sump internal partition and oil sump are set are welding.
Purge cock seat and oil sump are set are welding.
The mode that described locator protrusions is set is with punching press forms.
In the upper edge hole flange of the both sides of described oil sump, reinforced rib is set.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention forms locator protrusions by the junction plane at oil sump upper surface and framework, can guarantee the location of seal rubber pad on the one hand; On the other hand, can guarantee the decrement of seal rubber pad, can not cause because the compression of pad is too big or too little.
2, oil sump both sides upper edge hole increases the reinforced rib that is provided with among the present invention, can play the effect of packing ring, increases sealing reliability, has therefore omitted packing ring simultaneously, reduces cost.
3, the present invention increases the purge cock seat at the purge cock place, has guaranteed the reliable sealing at purge cock place.
4, the present invention is welded as a whole oil sump internal partition and oil sump, when satisfying reduction machine oil air content, has reduced the quantity of part.
Description of drawings
Fig. 1 is the whole plan view of the present invention.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3 is the B-B view of Fig. 1.
Fig. 4 is the C-C view of Fig. 1.
Number in the figure: 1 flange, 2 oil sumps, 3 dividing plates, 4 oil sump upper surfaces, 5 reinforced ribs, 6 locator protrusionss, 7 purge cock seats, 8 purge cocks.
Below, in conjunction with the accompanying drawings invention is described further by embodiment.
Embodiment
Fig. 1, Fig. 2 and shown in Figure 3, present embodiment adopts the punching oil drain pan.On the oil sump upper surface 4 that combines with engine frame, punching press forms locator protrusions 6, and seal rubber pad is sleeved on the locator protrusions 6 with the positioning hole on the corresponding position; The cooperation of this locator protrusions 6 and seal rubber pad has not only guaranteed the location of seal rubber pad, and guarantees being compressed in the reasonable range of seal rubber pad.
Shown in Figure 4, on the drain oil position of oil sump 2, be welded with purge cock seat 7, screw-thread fit between purge cock 8 and the purge cock seat 7; Being connected between purge cock 8 and the purge cock seat 7 is very firm, has guaranteed the reliability of sealing.
Shown in Figure 2, oil sump internal partition 3 is set is integral structure, and oil sump internal partition 3 is welding with oil sump 2 with oil sump 2.Dividing plate 3 connects as one by the mode and the oil sump 2 of spot welding, has reduced the quantity of oilcan spare part, thereby also reduces cost.
Shown in Figure 4, in the upper edge hole flange of the both sides of oil sump 2, reinforced rib 5 is set, reinforced rib 5 plays the effect of packing ring, has guaranteed sealing reliability, because omitted packing ring, has reduced cost simultaneously.
