Abstract
The utility model discloses a turbocharger thrust bearing, which comprises a circular-disk bearing support, a circular bearing disk and a circular center hole, wherein the circular bearing disk is arranged in the center of the bearing support, and the circular center hole is arranged in the center of the bearing disk. An oil inlet is arranged on the bearing support; an oil inlet passage is arranged between the oil inlet and the center hole; an annular oil groove is arranged on the bearing support on the outer side of the bearing disk; a notch below the oil groove is an oil outlet; a plurality of oil outlet grooves are arranged on the bearing disk; and each oil outlet groove is communicated with the center hole. The turbocharger thrust bearing has the advantages of fine strength and good lubricating effect of the bearing.
Description
Technical field
The utility model relates to the technical field of bearings of dynamic power machine, is specifically related to a kind of thrust bearing that is used for turbosupercharger.
Background technique
At present, the existing thrust bearing that is used for turbosupercharger with the be coupling center hole that touches be the double wedge shape, each double wedge directly contacts with axle, this thrust bearing because and axle between supporting surface little, so poor stability, bearing weares and teares easily, the ability of carry-over moment, intensity difference, and the lubrication effect of this thrust bearing is bad, can not well satisfy the application need of thrust bearing of turbocharger.
Summary of the invention
The purpose of this utility model is to provide a kind of thrust bearing that can address this problem at the existing thrust bearing poor stability described in the background technique, bearing weares and teares easily and lubrication effect is bad problem.
The realization the technical solution of the utility model is as follows:
A kind of thrust bearing of turbocharger, it comprises discoidal bearing support, is arranged at the bearing dish of bearing support central circular and the center hole that is arranged at the circle of bearing disk center, described bearing support is provided with filler opening, be provided with oil inlet passage between this filler opening and the center hole, described bearing dish outboard shafts bearing is provided with the oil groove of annular, the breach of oil groove below is an oil outlet, and the bearing dish is provided with several fuel-displaced grooves, and each fuel-displaced groove all is communicated with described center hole.
In order to improve lubricating efficiency, described bearing support upper and lower surface is symmetrical arranged, and is the working surface of this thrust bearing of turbocharger.
In order to make the filler opening that passes through that lubricant oil can be stable enter in the center hole groove that described filler opening both sides are respectively arranged with waist shape.
Described bearing support is provided with several locating slots that is used for fixing bearing support.
The beneficial effects of the utility model are for because being shaped as of the center hole of bearing centre is circular, so the surface of contact of axle and bearing big than double wedge type, bigger to the support moment of bearing so its intensity is good, assembling is good; Because bearing support is provided with the filler opening that is communicated with center hole, the bearing dish at bearing support center is provided with fuel-displaced groove, bearing dish arranged outside has the oil groove of annular, the oil groove below is provided with oil outlet, can enter oil groove by fuel-displaced groove so enter the lubricant oil of center hole from filler opening, the lubricant oil gravitate flows out from the oil outlet that is arranged at the bearing support below then, can pass through endless form, the impurity of removing in the lubricant oil enters in the bearing by filler opening once more, realize the recycling of lubricant oil, this lubricant oil supply system can improve the lubrication effect of bearing effectively, can improve the utilization ratio of lubricant oil simultaneously.
Description of drawings
Fig. 1 is a schematic representation of the present utility model;
Fig. 2 is that A of the present utility model is to generalized section;
Among the figure, 1 is bearing support, and 2 is locating slot, and 3 is the bearing dish, and 4 is filler opening, and 5 is center hole, and 6 is oil inlet passage, and 7 is oil groove, and 8 is oil outlet, and 9 is fuel-displaced groove, and 10 is the waist connected in star.
Embodiment
With reference to a kind of thrust bearing of turbocharger shown in accompanying drawing 1 and the accompanying drawing 2, the center hole 5 that it comprises discoidal bearing support 1, is arranged at the bearing dish 3 of bearing support 1 central circular and is arranged at bearing dish 3 central circular, described bearing support 1 is provided with filler opening 4, be provided with oil inlet passage 6 between this filler opening 4 and the center hole 5, described bearing dish 3 outboard shafts bearings are provided with the oil groove 7 of annular, the breach of oil groove 7 belows is an oil outlet 8, bearing dish 3 is provided with several fuel-displaced grooves 9, and each fuel-displaced groove 9 all is communicated with described center hole 5.Lubricant oil enters in the center hole 5 of thrust bearing of turbocharger from filler opening 4 by oil inlet passage 6, can realize lubricating between axle and the thrust bearing of turbocharger, in axle high speed rotating process, unnecessary lubricant oil enters in the oil groove 7 by fuel-displaced groove 9 under action of centrifugal force, the lubricant oil that enters in the oil groove 7 flows out by oil outlet 8 under the effect of gravity, can pass through endless form, the impurity of removing in the lubricant oil enters in the bearing by filler opening 4 once more, realize the recycling of lubricant oil, this lubricant oil supply system can improve the lubrication effect of bearing effectively, the utilization ratio that can improve lubricant oil simultaneously enters in the center hole in order to make the filler opening that passes through that lubricant oil can be stable, described filler opening both sides are respectively arranged with waist connected in star 10, because oil inlet passage 6 is narrow, so lubricant oil can be introduced in the waist connected in star 10 from filler opening 4 enters the process of oil inlet passage 6, by the time the lubricant oil after the lubricant oil in the oil inlet passage 6 flows in the center hole 5 in the waist connected in star 10 can be continuously introduced in the center hole 5, guarantees the sustainable supply of lubricant oil.Described bearing support 1 is provided with several locating slots that is used for fixing bearing support 2.
Because being shaped as of the center hole 5 at bearing support 1 center is circular, so the surface of contact of axle and bearing big than double wedge type, so its intensity is good, bigger to the support moment of bearing, assembling is good; Because bearing support 1 is provided with the filler opening 4 that is communicated with center hole 5, the bearing dish at bearing support center is provided with fuel-displaced groove 9, bearing dish arranged outside has the oil groove 7 of annular, the oil groove below is provided with oil outlet 8, can enter oil groove 7 by fuel-displaced groove 9 so enter the lubricant oil of center hole 5 from filler opening 4, the lubricant oil gravitate flows out from the oil outlet 8 that is arranged at the bearing support below then, can pass through endless form, the impurity of removing in the lubricant oil enters in the bearing by filler opening once more, realize the recycling of lubricant oil, this lubricant oil supply system can improve the lubrication effect of bearing effectively, can improve the utilization ratio of lubricant oil simultaneously.
