The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, burning chamber shell of the present utility model, the wheel chamber casing 1 that comprises casting, wheel chamber casing 1 have the casing wall body 11 that is horn-like shape, link to each other with the flared end of casing wall body 11 and be the taper beam 12 of centrum shape and link to each other with the serrated end of taper beam 12 and be the bearing end seat 13 that overlaps tubular.According to burning chamber shell of the present utility model, wheel chamber casing 1 is by the casting technique moulding, characteristics in view of casting technique, can be by the foundry goods of casting technique moulding, its wall thickness is generally thicker, so compare existing housing by the panel beating moulding, the wall thickness of wheel chamber casing 1 has increased, so adopt the vibration of the combustion box of this wheel chamber casing 1 to reduce, thereby its distortion will reduce; Again because wheel chamber casing 1 by casting integrated moulding, so in use, wheel chamber casing 1 is not easy to ftracture, service life is longer.
Particularly, wheel chamber casing 1 comprises casing wall body 11, taper beam 12 and the bearing end seat 13 that links to each other successively, and wherein, casing wall body 11 is horn-like, has a plurality of support plates 10 that protrude along its center axis on its inwall; Taper beam 12 is the centrum shape, and its flared end links to each other with support plate 10, and its serrated end stretches out along the flared end of casing wall body 11; Bearing end seat 13 is the cover tubular, and the one end links to each other with the serrated end of taper beam 12.In the utility model, wheel chamber casing 1 comprises casing wall body 11, taper beam 12 and bearing end seat 13, and the three is by casting integrated moulding, and position relation each other is more accurate; And one-body moldedly reduced the required welding position of casing following process, reduced the fault rate in the casing use.
In the utility model, owing in the combustion box many important gas channels are arranged, compare existing panel beating housing, wall thickness by the wheel chamber casing 1 behind the casting has increased, but in order not influence the service behaviour parameter of the combustion machine that this wheel chamber casing 1 is housed, the wall thickness of the existing relatively panel beating housing of the wall thickness of wheel chamber casing 1 to thicken direction all inequality at its each position, casing wall body 11 is at its all circle external upset (EU)s to 10～13mm, taper beam 12 is for thickening to 10～13mm to the center axis direction on the wall within it, and bearing end seat 13 is for thickening to 10～13mm to the center axis direction on the wall within it.Preferably, because the thickening direction of wheel chamber casing 1 is determined, because the outer setting of wheel chamber casing 1 has pipeline and the circuits that much are connected with the combustion machine, if the wall thickness of wheel chamber casing 1 is blocked up, will collides with pipeline and circuit and influence assembling; In addition, has multiple mount pad on the wheel chamber casing 1, for continuing to continue to use the pipeline circuit that links to each other with former wheel chamber casing, the position of mount pad can not change, thereby limited the increase of wall thickness, so both thickness of casing wall body 11 and taper beam 12 is 10mm, the thickness of bearing end seat 13 is 12mm, because bearing end seat 13 is the important load parts on the combustion machine, the weight of wheel chamber casing 1 rehandling spare after-combustion casing own increases, be to improve intensity, the thickness of bearing end seat 13 is because of bigger than both thickness of casing wall body 11 and taper beam 12.Compare existing panel beating housing, because the increase of the wall thickness of wheel chamber casing 1, so the weight of wheel chamber casing 1 increases, thereby the weight of combustion box increases, and the vibration of combustion box when work will reduce, so its distortion will reduce, and foundry goods is not easy to crack, and will increase the service life of wheel chamber casing 1.
Preferably, the material category of foundry goods is more, and common have iron, steel, a copper etc., in the utility model, the material of wheel chamber casing 1 is martensitic stain less steel, and its machine adds performance and welding performance is good, anti-fresh water and wet atmospheric corrosion are so can increase the service life of wheel chamber casing 1.
In the utility model, have many on the Zhou Yuan of casing wall body 11 and be used for the gas channel 20 that air guide and Oil Guide are used, wherein, some gas channel 20 extends to its internal cavity from the Zhou Yuan of casing wall body 11; Another part gas channel 20 extends to outside the Zhou Yuan of taper beam 12 from the Zhou Yuan of casing wall body 11, and in the present embodiment, the bar number of gas channel 20 is 4.
Further, carry out oil return for making things convenient for the lubricating oil in the wheel chamber casing 1, so have a plurality of spill ports 30 for oil return on the inwall of casing wall body 11.In addition, for the wheel chamber casing 1 behind the casting is connected with outside parts, so all have a circle installation base 40 of outside protrusion on the serrated end of casing wall body 11 and the Zhou Yuan of flared end, and have on the installation base 40 for the installing hole 50 that wheel chamber casing 1 is installed, after adopting connectors such as screw or bolt to pass installing hole 50 and outside parts, wheel chamber casing 1 is connected with outside parts.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
According to burning chamber shell of the present utility model, wheel chamber casing is by the casting technique moulding, the casing wall body of the wheel chamber casing after the moulding and the thickness of taper beam all increase to 10mm, the thickness of bearing end seat increases to 12mm, compare the thick 2.5mm of existing panel beating housing, because the increase of the wall thickness of wheel chamber casing, so adopt the overall weight of the combustion machine of this wheel chamber casing to increase, the vibration of combustion machine when work reduces, thereby its distortion reduces; Again because wheel chamber casing by casting integrated moulding, wheel chamber casing is not easy cracking, combustion growth in machine service life.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
