Abstract
The utility model discloses an oil wedge thrust bearing for a turbocharger. An inner ring of a main thrust surface is a conical surface and is provided with a ring-shaped oil wedge. An outer ring of the ring-shaped oil wedge is provided with an oil wedge platform. A plurality of oil inlet holes are distributed on the oil wedge platform. The main thrust surface and an auxiliary thrust surface have totally consistent structures. In the utility model, the characteristic of high reliability of the oil wedge thrust bearing is effectively utilized. The oil wedge thrust bearing for the turbocharger is beneficial to stability of high-speed operation of a shaft, is simple to process, has low cost and can be applied to a supercharger with a random spindle rotating direction. Meanwhile, the service life of the thrust bearing is nearly doubled.
Description
Technical field
The utility model relates to bearing technology, specifically refers to the thrust-bearing of turbosupercharging metal v-belt oil film wedge.
Background technique
The thrust-bearing of exhaust-gas turbocharger design at present mainly contains two kinds of structures: thrust is worn oil film wedge and thrust face not with the structure of oil film wedge.
One, thrust is worn the structure of oil film wedge: the thrust-bearing of this kind band oil film wedge is widely used in the ship turbine pressurized machine, and in centrifugal compressor and other turbomachinery, these equipment price height, particularly main shaft price height need to guarantee the bearing reliable in function that the life-span is long.The maximum characteristics of this kind bearing are that the people is for processing oil film wedge on the thrust face, and oil film wedge can stabilizing effectively be offset the end thrust of pressurized machine.
The shortcoming of this kind bearing is: 1, adopt the Cuprum alloy forging to process, difficulty of processing is big, and work efficiency is low, and oil film wedge quantity is many more and the oil film wedge area is big more, and processing cost is high more.2, along the high point (being called the oil film wedge lift) that circumferentially progressively is elevated to the fuel-displaced limit of oil film wedge, its direction that rotates in a circumferential direction need be consistent with the rotation direction of axle from the low spot on oil film wedge oil-feed limit for this kind bearing oil wedge surface.3, (point to the gas compressor end) much larger than pressurized machine augmented thrust (sensing turbine end) because the pressurized machine main thrust, therefore the structural design of thrust-bearing main thrust face and augmented thrust face is different, usually the oil film wedge external diameter of augmented thrust face is less than the main thrust face, and oil film wedge face size and oil film wedge lift and main oil film wedge face are also different.Behind the main thrust surface wear (in most cases, the augmented thrust face is more not wearing and tearing), but the bearing that the user can only renew.Be generally the projected life of this kind bearing 25000 hours, the practical application life-span can only guarantee half.
Two, thrust face is not with the structure of oil film wedge: add and oil film wedge is not processed man-hour, even the oil film wedge oil-feed tank does not process yet.Such structure is extensive use of in vehicle supercharger.The great advantage of this kind bearing is can the powder metallurgy extrusion modling, and processing is simple, the work efficiency height, and cost is low.Irrelevant with the rotation direction of axle simultaneously.The disadvantage of this kind bearing is that bearing thrust is less, and reliability is general, generally is used to the vehicle supercharger of producing in enormous quantities.
The model utility content
At the prior art above shortcomings, the purpose of this utility model just is to provide the thrust-bearing of the long turbosupercharging metal v-belt oil film wedge of a kind of favorable working performance, easy processing, life-span.
To achieve these goals, the technical solution adopted in the utility model is such: the thrust-bearing of turbosupercharging metal v-belt oil film wedge, have main thrust face and augmented thrust face, described main thrust face inner ring is that cone-shaped circularizes oil film wedge, annular oil film wedge outer ring is furnished with the oil film wedge platform, arranges some oil inlet holes on the oil film wedge platform.
Further, described main thrust face and augmented thrust face structure are in full accord.
Compared to existing technology, the utlity model has following beneficial effect:
1, annular oil film wedge has effectively utilized band oil film wedge thrust-bearing high reliability features.
2, the counter-force of the opposing axle thrust of annular oil film wedge generation is slight entad (a sensing axle gyration center), rotating speed is high more during the pressurized machine operation, pressure ratio is big more, the end thrust that axle points to the gas compressor end from turbine end is just big more, the resistant function power that the annular oil film wedge produces is also big more, entad component is just big more for it, helps the stability of a high speed operation.
3, because annular oil film wedge is irrelevant with the rotation direction of axle, so this thrust-bearing can be applicable to main shaft rotation direction pressurized machine arbitrarily.
4, the processing of annular oil film wedge is simple, and cost is low.
5, two of thrust-bearing thrust face structures are just the same, one side as the main thrust face reach wear limit the time, thrust-bearing is fallen face installs, can make full use of the characteristics that the augmented thrust face not have wearing and tearing substantially, nearly one times of prolongation thrust-bearing life-span.
Description of drawings
Fig. 1-the utility model structural representation.
Fig. 2-the utility model sectional drawing.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, from the figure as can be seen, the thrust-bearing of the utility model turbosupercharging metal v-belt oil film wedge is in conjunction with the advantage of aforementioned two kinds of thrust-bearings, avoid the thrust-bearing design method that its shortcoming has adopted new structure again, it has main thrust face 1 and augmented thrust face 2, described main thrust face 1 inner ring is designed to cone-shaped and circularizes oil film wedge 3, when the thrust block pad high speed rotating that cooperates with thrust-bearing on the axle, lubricating oil is got rid of from bearing centre toward periphery, it is thick just to form internal diameter, the annular oil film wedge that external diameter is thin.Annular oil film wedge 3 outer rings are furnished with oil film wedge platform 4, arrange some oil inlet holes 5 on the oil film wedge platform 4.The oil film wedge platform forms the consistent planar annular oil film of thickness with thrust block pad can offset the end thrust of pressurized machine by the means of complementary annular oil film wedge.
Further, described main thrust face 1 and augmented thrust face 2 structures are in full accord.When reaching wear limit, thrust-bearing is fallen a face install, can make full use of the characteristics that the augmented thrust face not have wearing and tearing substantially, nearly one times of prolongation thrust-bearing life-span as one side of main thrust face.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
