Abstract
The utility model discloses a floating bearing for inhibiting the hyposynchronous vibration noise of turbocharger. The floating bearing comprises a bearing main body, wherein a plurality of oil supply holes communicated with an inner hole of the bearing main body are formed in the bearing main body; at least three axial oil grooves are uniformly formed in the working surface of the inner hole of the bearing main body. The floating bearing has the advantages that the axial oil grooves formed in the working surface of the inner hole of the bearing main body can be used for adjusting and balancing the inlet oil flow and return oil flow of the floating bearing, so that the induction of whirling of an inner oil film of the floating bearing is radically inhibited, the hyposynchronous vibration noise of the turbocharger is effectively inhibited, and the working stability of a rotor system of the turbocharger is improved.
Description
Technical field
The utility model relates to a kind of floating bearing, especially relates to a kind of for suppressing the floating bearing of turbosupercharger subsynchronous vibration noise.
Background technique
Floating bearing is because it is simple in structure, the low vehicle turbocharger rotor support structure that is widely used in of cost, and floating bearing is divided into full floating and two kinds of structures of semifloating conventionally.Interior oil film and the outer oil film of full floating bearing are dynamic pressure oil film, offer rotor yielding support, provide again damping to play cushioning effect; The interior oil film of semifloating bearing is the same with the interior oil film of full floating bearing is dynamic pressure oil film, but because the floating ring of semifloating bearing is without rotation, therefore the outer oil film of semifloating bearing is squeeze film, and damping is only provided, and plays cushioning effect.
Along with the popularization of energy-saving and emission-reduction policy, turbosupercharger is more and more used on passenger car and car, and for meeting the requirement of car comfort, vibration and noise must strictly be controlled.The noise of turbosupercharger is varied, wherein allow user be difficult to most accept be the lasting whistler of subsynchronous vibration.Research finds that the interior oil whirl of floating bearing is the basic reason of bringing out subsynchronous vibration noise, therefore, is necessary the structure of floating bearing to improve, to suppress turbosupercharger subsynchronous vibration noise.
Summary of the invention
Technical problem to be solved in the utility model is to provide one can suppress turbosupercharger subsynchronous vibration noise effectively, and improves the floating bearing of the rotor-support-foundation system working stability of turbosupercharger.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of for suppressing the floating bearing of turbosupercharger subsynchronous vibration noise, comprise bearing main body, on described bearing main body, be provided with the oil supply hole that the endoporus of multiple with described bearing main body is connected, it is characterized in that evenly offering at least three axial oil grooves on the working surface of endoporus of described bearing main body.
The shape of cross section of described axial oil groove is V-arrangement or for U-shaped or for semicircle, the axial oil groove of these several shapes is convenient to manufacturing.
When the shape of cross section of described axial oil groove is V-arrangement, the bottom land of described axial oil groove is rounding structure.
Described axial oil groove is connected with described oil supply hole, and the logical oil of axial oil groove is smooth and easy, and fuel-flow control susceptibility is high, response is fast, is conducive to the stability of the rotor that maintains in real time turbosupercharger.
Compared with prior art, the utility model has the advantage of: the axial oil groove that utilization is offered on the working surface of the endoporus of bearing main body, can regulate also oil-feed flow and the oil return flow of balance floating bearing, fundamentally suppress the bringing out of interior oil whirl of floating bearing, effectively suppress turbosupercharger subsynchronous vibration noise, promoted the working stability of the rotor-support-foundation system of turbosupercharger; In addition, axial oil groove also has the effect of oil-containing, though like this of short duration for the shortage of oil in the situation that, in axial oil groove, contained lubricant oil also can play the effect of supplemental lubrication to a certain extent, ensure that turbosupercharger maintains normal working, extended the working life of turbosupercharger.
