Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Fig. 1 is the turbocharger schematic diagram that the present invention has bearing self-return function, as shown in Figure 1, the present embodiment
Turbocharger may include:
Booster turbine end housing, compressor end housing, intermediate, pressure side seal, ground feet support and through described
The rotor of booster turbine end housing and the compressor end housing, the bearing that transverse bearing, center of gravity are not overlapped with geometric center
Shell；
The transverse bearing is set to the rotor outer periphery, and the bear box is set to the transverse bearing periphery.
Specifically, lateral swing will be direct among these since marine diesel oil chance is with wave random swing at random
Influence the rotor condition of booster.When diesel engine horizontal swing when, booster due to being fastenedly connected with diesel engine ground feet support,
So also together, random transverse direction can be done therewith with including compressor end housing, intermediate, pressure side seal, turbine end housing
It swings.Turbocharger works with diesel engine, through-flow by compressor impeller and generator terminal of calming the anger by air from generator terminal sucking of calming the anger
It is discharged after element from compressor end housing, after participating in work by combustion, exhaust gas enters booster turbine end housing, and drive rotor turns
It is dynamic, booster is finally discharged.Rotor is supported by pressure side and two transverse bearing of whirlpool end, and transverse bearing oil film wedge face is located at rotor main shaft
Underface, the oil film wedge power generated when rotor rotates with bearing is by rotor picking-up.
Therefore bear box is not overlapped at center with geometric center, therefore after swinging laterally, bear box can be always
Keep vertical state.
Further, further includes:
It is set to the rolling bearing of the bearing periphery.
Specifically, the present embodiment is responsible for supporting and reducing the frictional force with intermediate by rolling bearing.Booster lubrication
Oil enters intermediate by lubricating oil inlet, then before entering bear box, takes the lead in being lubricated to rolling bearing, can be most
The reduction of big degree is passed to the circumferential torque of bear box by intermediate circuit oscillation, and then reduces cartridge housing to the greatest extent
The circuit oscillation of body and transverse bearing, seal oil tooth are that will cause supercharger lubricating oil not when to rolling bearing lubrication
Gap oil leakage of the lubricating oil between intermediate and bear box, the supercharger lubricating oil are flowed out by lubricating oil outlet.
Further, the bear box includes:
First shell and second shell, the density of the first shell are greater than the density of second shell, the first shell
Corresponding angle of circumference is not more than the corresponding angle of circumference of the second shell.
Specifically, the density of the bear box first shell of the present embodiment is greater than the density of second shell, thus bearing
The center of gravity of shell, being capable of rapid return when diesel engine horizontal swing below geometric center.
Further, the bear box includes:
The protrusion being set to outside bear box circumference.
Specifically, as shown in Fig. 2, bear box remains vertical under the action of its own centre of gravity adjustment centering block
State.And it can be repositioned to original state rapidly under the adjustment of centre of gravity adjustment centering block pendulum model, no longer interfered by external shell part,
The oil film wedge power size and Orientation that ensure that transverse bearing generates is always consistent, breaks the axes movement locus of rotor not
It is bad.
Further, the bear box includes:
First shell and second shell, the density of the first shell are greater than the density of second shell, the first shell
Corresponding angle of circumference is not more than the corresponding angle of circumference of the second shell, the protrusion being set to outside the first shell circumference.
Specifically, the density of the bear box bear box first shell of the present embodiment is greater than the density of second shell,
To bear box center of gravity below geometric center, when diesel engine horizontal swing when being capable of rapid return.And first shell
Circumference outside be arranged protrusion further speeded up bear box return.It improves work efficiency.
The present invention has the advantages that new supercharger structure will not change the interface mode of original booster and diesel engine
And size, booster machine shape size and complete machine bulk wight amount are not impacted, booster overall performance will not be lost；Increase
Supercharger rotor antiwhip and reliability, reduce supercharger rotor with housing component because the friction that contacts with each other causes to damage
Bad a possibility that；Original intermediate is divided into two parts, enhances the module interchangeability of booster homologous series different model, no
Same bearing rotor structure, until needing to change bear box can be realized exchange, is reduced and is set in the case where being changed without housing component
Manufacturing cost is counted, efficiency is improved.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
