Description

Hybrid ceramic ball bearing on turbocharger
Technical field
The utility model relates to a kind of bearing, relates in particular to the hybrid ceramic ball bearing on a kind of turbosupercharger.
Background technique
Motor adopts turbocharging technology can increase substantially power, reduce exhaust pollution, improve economic performance, and turbosupercharging is one of topmost technological development direction of internal-combustion engine.Therefore, turbosupercharger has obtained increasingly extensive application in recent years.At present, whole world commercial car (truck, motorbus) disposes pressurized machine more than 90%, and passenger car about 10% has adopted pressurized machine.Developing direction is 100% turbosupercharging.The demand growth of whole world turbosupercharger at present increases progressively with the ratio more than 10%, domesticly then increases progressively with about 30% ratio.Therefore the turbosupercharger market demand is huge, has a extensive future.
Turbosupercharger generally adopts (oil film) bearing at present, its important failure mode is that (oil film) bearing arrangement lost efficacy, mainly be unsteady (oil film) bearing and thrust bearing friction damage, make pressurized machine bearing rotor system balance destruction, impeller grazing housing, cause pressurized machine to damage, turbocharger applications (oil film) bearing is had relatively high expectations to the pressure of engine lubrication system, temperature, filtering precision etc., and is not allowed oil-break.
Summary of the invention
In order to solve the problem of above-mentioned existence, the purpose of this utility model provides a kind of high mechanical efficiency, low lubricating requirement (even can of short duration oil-break), the simpler bearing arrangement structure of structure, with the hybrid ceramic ball bearing on turbocharger of the mechanical efficiency, reliability and the startability that improve turbosupercharger.
The technical solution of the utility model is achieved in that a kind of hybrid ceramic ball bearing on turbocharger, comprise inner ring, outer ring and retainer, wherein between inner ring and outer ring, two row's ceramic ball are set near the place, both sides, every row's ceramic ball is provided with retainer outward, and inner ring, outer ring, ceramic ball and retainer are together with the back to back structure form angular contact bearing that partners.
Two rows about described ceramic ball and retainer are divided into.
Ceramic ball is installed on the booster turbine rotor shaft for convenience, and described inner ring is divided into left and right sides two-part.
Have two oil inlet holes on top, described outer ring, the bottom has an oil outlet.
In order to make the installing and locating of ceramic ball on the pressurized machine bearing support, have a positioning hole on top, described outer ring.
Compared with prior art the beneficial effects of the utility model are:
1, uses the utility model, will increase substantially the pressurized machine mechanical efficiency, improve the reliability of turbosupercharger, improve pressurized machine working life;
2, reduced requirement to engine lubrication system;
3, improved transient response, the startability of pressurized machine, so improved motor acceleration performance.
4, cancelled thrust bearing, appropriate change inner ring length and shape can reduce other parts such as sealing great waves on the supercharger rotor axle, simplify the bearing arrangement structure.
Description of drawings
Fig. 1 is the utility model hybrid ceramic ball bearing on turbocharger internal structure schematic representation;
Fig. 2 is that the A of hybrid ceramic ball bearing on turbocharger shown in Figure 1 is to view.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but not as to qualification of the present utility model.
Hybrid ceramic ball bearing on turbocharger as shown in Figure 1, a kind of hybrid ceramic ball bearing on turbocharger, comprise inner ring 1, outer ring 2, ceramic ball 3, retainer 4, two rows about wherein ceramic ball 3 is divided into retainer 4, ceramic ball 3 and retainer 4 are between inner ring 1 and outer ring 2.Two row's ceramic ball 3, two retainers 4 and inner ring 1, outer ring 2 are with the back to back structure form angular contact bearing that partners, to bear the axial load of booster turbine rotor.
Inner ring 1 is divided into left and right sides two-part, so that be installed on the booster turbine rotor shaft.2 tops have two oil inlet holes, bottoms and have an oil outlet in the outer ring, and 2 tops, outer ring have a positioning hole, and the effect of positioning hole is to make the installing and locating of outer ring 2 on the pressurized machine bearing support.The wrapping angle size of this angular contact bearing is determined according to pressurized machine model specification.In order to be suitable for the needs of different model pressurized machine bearing structure, inner ring 1 two ends all can stretch out or indentation outer ring 2 outside suitable length, the position of two oil inlet holes 5, oil outlet 6 and positioning holes 7 also can be axially and corresponding change on the circumferencial direction.For easy for installation, can with suitable minimizing resistance be installed processing the groove of the proper width and the degree of depth on the inner headed face of inner ring 1 with on the periphery of outer ring 2.This structure is suitable for pressurized machine bearing rotor system structure, has reduced lubricating requirement, has improved pressurized machine mechanical efficiency, transient response and working life, and then has improved the performance of motor.
