Advise according to the present invention that at this along the tangent direction of annular pass an input hole that is used for oiling agent is led to the annular pass of fixing bearing support, wherein, a nozzle is integrated in this input hole.The oiling agent that will have a vortex component with method is incorporated in this annular pass in this manner, the centrifugation from oiling agent of foul particle can be come out when stationary axle thus.For the foul particle that general's centrifugation comes out is discharged, on the annular pass, connect a tap hole from the annular pass radially outerly.According to the scheme of bearing means of the present invention can be in cod also can be in radial bearing before the foul particle enters into this bearing just can with its effectively centrifugation come out, and therefore from the annular pass, remove this foul particle.Therefore can avoid infringement effectively to bearing.
Description of drawings
By producing other preferred improvement project of the present invention in dependent claims and the following explanation.By accompanying drawing one embodiment of the present of invention are described in detail, but the present invention is not limited to this embodiment.These accompanying drawings are:
Fig. 1: according to one of bearing means of the present invention fixing bearing support;
Fig. 2: the bearing support of fixing among Fig. 1 is along the cross-sectional view of II-II hatching.
Embodiment
The present invention will be described in more detail below with reference to Fig. 1 and Fig. 2.
Fig. 1 and Fig. 2 represent according to one of bearing means of the present invention fixing bearing support 10.This bearing means preferably is designed for the so-called thrust-bearing or the cod of exhaust-gas turbocharger.Pit 11 in the middle of this bearing support 10 has one, it is used to support the axle that moves with respect to rigid bearing body 10, and wherein, an annular pass 12 is connected with this pit 11 radially outerly.Annular pass 12 is used for the oiling agent guiding for the lubricating bearings device.By the annular space of annular pass 12 and formation between one of this pit 11 radially built-in wall 13 and unshowned axle, can be in this bearing with lubricant delivery.
According to the present invention, one is integrated in the fixing bearing support 10 according to bearing means of the present invention with the tangential sprocket holes 14 that extend in annular pass 12 at this.This sprocket hole is used for lubricant delivery to the annular pass 12, and annular pass 12 and a groove 15 that is integrated into fixing bearing support 10 are coupled together radially outerly.A nozzle 16 is integrated in this sprocket hole 14, in order that at last oiling agent is directed in the annular pass 12.By sprocket hole 14 and be integrated into nozzle 16 in the sprocket hole 14 with respect to the tangential sensing of annular pass 12, make oiling agent tangentially direction be transported in the annular pass 12, wherein, in annular pass 12, form one eddy flow by this measure.Because eddy flow, the foul particle that makes in oiling agent to be comprised is separated by centrifugal force, and arrives the radially external wall 17 of annular pass 12.A tap hole 18 is connected with annular pass 12 radially outerly, in order that foul particle that will centrifugation is come out from oiling agent is discharged from annular pass 12.
Just as already mentioned, sprocket hole 14 tangentially extends with respect to annular pass 12, wherein according to Fig. 1, and the inclined setting of sprocket hole 14 and fixing bearing support 10.By the tangential setting of sprocket hole 14, even when maintaining static, axle in annular pass 12, just formed the eddy flow of having mentioned with respect to annular pass 12.When axle rotated, eddy flow that one is induced by the rotation of axle and the eddy flow of inducing with respect to the tangential sensing of annular pass 12 by sprocket hole 14 pointed in the same way, and these eddy flows are overlapping and strengthen, and do not have the opposite effect each other each other like this.Sprocket hole 14 so designs with respect to the tangential sensing of annular pass 12, promptly strengthens by the tangential extension of sprocket hole the eddy flow of caused oiling agent in annular pass 12 when axle rotates.
Tap hole 18 is connected with annular pass 12 radially outerly, and this annular pass is connected with an oil drain out.According to Fig. 2, tap hole 18 is obliquely installed with respect to the axial direction of fixing bearing support 10.Tap hole 18 also can tangentially extend with annular pass 12 as sprocket hole 14.
Tap hole 18 has an enough big cross section, in order that foul particle that also can delivery ratio is bigger from annular pass 12.Yet the cross section of tap hole 18 is sufficiently little, in order that make the lubricant pressure loss that is caused by tap hole 18 as far as possible little.Therefore, the cross section of tap hole 18 is than the radially built-in wall by pit 11 13 be bearing in that annular space that the unshowned axle in this pit 11 limited is little manys times.
Utilization is according to of the present inventionly both being designed to cod, also can being designed to the bearing means of radial bearing, exactly be before oiling agent arrives the described zone of this bearing, just can effectively the foul particle be come out from the oiling agent centrifugation that is used for the lubricating bearings device, and therefore discharge described foul particle.Avoid bearing impaired by this measure, and the working life of therefore improving bearing.
