Abstract
The utility model discloses an improved turbine shaft of a supercharger. The improved turbine shaft comprises a worm wheel and a worm which are coaxially arranged; the worm is fixed on the worm wheel; a hollow part is arranged between the worm wheel and the worm; the hollow part is arranged on the axis of the worm wheel and the worm; the worm wheel and the worm are welded together by adopting an electron beam welding technology; the outer surface of the worm is provided with a sealing groove; and the sealing groove is close to one end of the worm wheel. The turbine shaft is simple in structure; and according to the turbine shaft, the hollow part is formed by hollowing the welded position of the worm wheel and the worm, so that heat transfer from the turbine end to an intermediate can be effectively blocked, the lubricating quality of lubricating oil at the turbine end is ensured, and the problems that the turbine shaft is blocked and ground and the like because lubrication of a bearing fails are solved.
Description
Technical field
The utility model relates to a kind of turbosupercharger, relates in particular to a kind of improved booster turbine axle.
Background technique
In turbosupercharger; Turbocharging technology utilizes the waste heat overbottom pressure ability drive pressure mechanism of qi in the exhaust gases of internal combustion engines, improves the density of the induced air of motor, thereby increases substantially the power of motor; Reduce fuel consume; And significantly reducing the discharging of pollutant, turbocharging technology is to realize that combustion engine energy-saving reduces discharging, satisfies the key technology of increasingly stringent emission regulation demands, along with the development of turbosupercharger to small-sized, big capacity, high supercharging pressure level; Because high supercharging pressure level; The turbine end operating temperature of turbosupercharger is up to more than 850 ℃, because of the too high floating bearing that makes the booster turbine end of the reason temperature of heat transmission because of lubrication failure, produce turbine shaft stuck, grind problem such as axle.
The model utility content
The technical problem that the utility model solved is to provide a kind of improved booster turbine axle, has effectively blocked the heat transfer of turbine end to intermediate, has guaranteed the lubricating quality of turbine end lubricant oil.
The technological scheme of the technical problem that the utility model solved is: a kind of improved booster turbine axle, comprise the turbine and the scroll bar of coaxial setting, and scroll bar is fixed on the turbine, is provided with hollow portion between turbine and the scroll bar.
As optimized technical scheme, hollow portion is arranged on the axis of turbine and scroll bar.
As optimized technical scheme, turbine and scroll bar adopt vacuum electron beam welding technology to weld together.
As optimized technical scheme, the outer surface of scroll bar is provided with seal groove, and seal groove is near turbine one end.
Owing to adopted the improved booster turbine axle of technique scheme, be provided with hollow portion at turbine and scroll bar connecting part on the turbine shaft, can effectively block the heat transfer of turbine end to intermediate, increase service life of equipment, reduce lubricant oil and lost efficacy.
Because hollow portion is arranged on the axis of turbine and scroll bar, i.e. hollow portion, turbine and scroll bar coaxality have guaranteed the balance rotating of turbine shaft, have increased the working life of turbine shaft.
Because turbine and scroll bar adopt vacuum electron beam welding technology; Because of the electron beam penetrability is strong, turbine welding end surface and scroll bar welding end surface fast thawing, welding tensile strength is greater than former mother metal; Turbine shaft machining allowance is little; Stock utilization is high, and the turbine shaft good stability is not yielding, and it goes without doing, and welding stress is handled.
Because scroll bar is provided with seal groove, is convenient on seal groove, be provided with seal ring.
This model utility is simple in structure; Turbine shaft adopts turbine and scroll bar weld to hollow out and handles the formation hollow portion; Can effectively block the heat transfer of turbine end to intermediate; Guaranteed the lubricating quality of turbine end lubricant oil, prevented to lose efficacy that the turbine shaft of generation is stuck, grind problem such as axle because of bearing lubrication.
Description of drawings
Fig. 1 is the structural representation of the improved booster turbine axle of the utility model;
Fig. 2 is the another kind of structural representation of the improved booster turbine axle of the utility model;
Among the figure: 1. turbine, 2. scroll bar, 3. hollow portion, 4 seal grooves.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the utility model, should be understood that these embodiments only be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Like Fig. 1, shown in Figure 2, a kind of improved booster turbine axle comprises the turbine 1 and scroll bar 2 of coaxial setting; Scroll bar 2 is fixed on the turbine 1, is provided with hollow portion 3 between turbine 1 and the scroll bar 2, and hollow portion 3 is arranged on the axis of turbine 1 and scroll bar 2; Hollow portion 3 has dual mode, and a kind of is when scroll bar 2 diameters of axle hour, because of satisfying the diameter of axle intensity at seal groove 4 places; Then hollow portion 3 is that only design is on turbine 1; Another kind is when scroll bar 2 diameters of axle satisfy the diameter of axle intensity at seal groove 4 places, and hollow portion 3 all has hollow in turbine end and scroll bar end, and turbine 1 adopts vacuum electron beam welding technology to weld together with scroll bar 2; The outer surface of scroll bar 2 is provided with seal groove 4, and seal groove 4 is near an end of turbine 1.
Owing to adopted the improved booster turbine axle of technique scheme, be provided with hollow portion 3 in turbine 1 and scroll bar 2 connecting parts on the turbine shaft, scroll bar 2 is provided with seal groove 4; Can effectively block the heat transfer of turbine end to the pressurized machine intermediate, turbine 1 adopts vacuum electron beam welding technology with scroll bar 2, because the electron beam penetrability is strong; Turbine 1 welding end surface and scroll bar 2 welding end surface fast thawings; Welding tensile strength is greater than former mother metal, and turbine shaft machining allowance is little, and stock utilization is high; The turbine shaft good stability is not yielding, and it goes without doing, and welding stress is handled.This model utility is simple in structure; Turbine shaft adopts turbine 1 and scroll bar 2 welds to hollow out and handles the formation hollow portion; Can effectively block the heat transfer of turbine 1 end to intermediate; Guaranteed the lubricating quality of turbine 1 end lubricant oil, prevented to lose efficacy that the turbine shaft of generation is stuck, grind problem such as axle because of bearing lubrication.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.
The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
