Abstract
The utility model discloses a turbocharger anti-thrust bearing belonging to motive power machine technology. The utility model is characterized in that the turbocharger anti-thrust bearing comprises eight bearing blocks equispacing in a circle around the bearing, the blocks comprises an oil wedge bevel, block plans and oil grooves. The oil wedge bevel is arranged between the oil grooves and the block plans. The utility model greatly improves the bearing capacity of the bearing.
Description
Technical field: the utility model belongs to the technical field of bearings of dynamic power machine, is specifically related to a kind of thrust bearing of turbocharger.
Background technique: under the vehicular engine operating mode, for the pressurized machine of mesohigh ratio, the pressure range of supercharger air compressor and turbine is higher, and in the high pressure-charging and super high pressure-charging pressurized machine that are applicable to than high power engine, this point performance is particularly outstanding.The high dynamic change of the pressure of supercharger air compressor and turbine, caused the booster thrust bearing produced bigger thrust loading of having born, this will make a very bad impression to the mechanical efficiency and the thrust-bearing reliability of pressurized machine, on several pressurized machines, just thrust bearing load-carrying properties problem had once appearred, the thrust bearing wearing and tearing are very serious, and bearing capacity is low.
The model utility content: the utility model is just in order to solve the deficiencies in the prior art, and proposes a kind of thrust bearing of turbocharger.
The technical solution of the utility model is: a kind of thrust bearing of turbocharger, thrust bearing is made up of 8 bearing tiles that are uniformly distributed along the circumference, bearing tile is made up of oil film wedge inclined-plane, bearing tile plane and oil groove, and the oil film wedge inclined-plane is in the middle of oil groove and bearing tile plane.
The purpose of this utility model can also be further perfect by following steps: the oil film wedge on oil film wedge inclined-plane is 0.05-0.1mm deeply, cornerite is respectively 4/5 and 3/5 of bearing tile cornerite, the inclined-plane on oil film wedge inclined-plane is a space curved surface, and its border is surrounded by two sections circular arcs and two sections straight lines of crossing the center of circle.
The beneficial effects of the utility model: the plane thrust bearing is adopted in some design at present, the defective of this bearing is that bearing capacity is extremely low, plane bearing is difficult to obtain advantages of high bearing capacity under the normal clearance condition, as oil slick thickness 15 microns the time, bearing capacity is 510 newton, and the thrust bearing bearing capacity that improves design is 4680 newton, is 9.2 times of plane bearing scheme.
Description of drawings: the utility model has 2 width of cloth accompanying drawings, and wherein Fig. 1 is a most preferred embodiment of the present utility model, also can make the specification digest accompanying drawing.
Fig. 1, be structural representation of the present utility model;
Fig. 2, be that the A-A of Fig. 1 is to sectional view.
Embodiment: most preferred embodiment of the present utility model is described further below in conjunction with accompanying drawing:
Most preferred embodiment of the present utility model as shown in Figure 1, 2, a kind of thrust bearing of turbocharger, thrust bearing 1 is made up of 8 bearing tiles that are uniformly distributed along the circumference, bearing tile is made up of oil film wedge inclined-plane 2, bearing tile plane 3 and oil groove 4, and oil film wedge inclined-plane 2 is in the middle of oil groove 4 and bearing tile plane 3.The oil film wedge on oil film wedge inclined-plane 2 is 0.05-0.1mm deeply, cornerite along circumference is respectively 4/5 and 3/5 of bearing tile cornerite, the inclined-plane on oil film wedge inclined-plane 2 is space curved surfaces, and its border is surrounded by two sections circular arcs and two sections straight lines of crossing the center of circle, and the remaining part of bearing tile is made up of bearing tile plane 3.The thrust bearing internal diameter is 20 millimeters; The thrust bearing external diameter is 40 millimeters.
Thrust bearing 1 is installed on the turbosupercharger, and thrust bearing 1 is pressed on the bearing support by back of the body dish or screw, and oil supply gallery communicates with the bearing support oil supply gallery, and two thrust plates are by the running shaft driven rotary, and thrust bearing 1 maintains static.
