Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect,
Below in conjunction with detailed description of the invention, the present invention is expanded on further.
As it is shown in figure 1, air-cooled bearing arrangement of the present invention include bearing block 100, bearing bracket stand 200,
Bearing cap 300, pump shaft 50 and axle journal 510, wherein, bearing block 100 center is located at by pump shaft 50,
This bearing block 100 is the cylindrical shell of a hollow, its with bearing bracket stand 200, axle journal 510 and bearing 540,
550 form an oil closed cavity 110, and for accommodating for cooling and the oil of lubrication, bearing block 100 lower end sets
Having a bottom surface 120, this bottom surface 120 is provided with fuel outlet and the interface for external temperature measuring equipment, separately at it
Sidewall is provided with oil-in for external permanent oil level indicator, the instruction of the oil level for being automatically adjusted in oil pocket 110
Scale 35；It addition, bearing block 100 is provided with the support rim 130 of an annular for disposing lower thrust axis
Hold 550, be used for bearing axial load.
Axle journal 510 is sheathed on pump shaft 50, and is placed in bearing block 100；Axle journal 510 and pump shaft
Being additionally provided with the oil sealing bucket 51 for stopping oil between 50, in the present embodiment, oil sealing bucket 51 uses seamless
Steel pipe is made.The bottom surface 120 of bearing block 100 coordinates with the leave from office terrace 53 of oil sealing bucket 51 and fixes,
It is additionally provided with O RunddichtringO 52 between this bottom surface 120 and leave from office terrace 53.
Bearing bracket stand 200 is fixedly installed on above bearing block 100, and this bearing bracket stand 200 sets around pump shaft 50
Putting, journal bearing 540 is located between bearing bracket stand 200 and axle journal 510, is used for carrying radial force.
Bearing cap 300 is located at above bearing bracket stand 200, and this bearing cap 300, bearing bracket stand 200 are by a spiral shell
Bolt 201 is fixed on bearing block 100；Pump shaft 50 together with the axle journal 510 being sheathed on outside pump shaft 50 from
Bearing cap 300 center is stretched out, and bearing cap 300 is provided with the felt circle 301 of annular, this felt circle 301
Specifically be located at axle journal 510 coordinate between face, to prevent oil leakage from going out bearing cap 300 and external dust
Internal Deng entering bearing block 100.
Fan board 520 is located at axle journal 510 top above bearing cap 300, and this fan board 520 passes through spiral shell
Stricture of vagina is tightened on pump shaft 50, and is fixed on the end face on axle journal 510 top by bolt 523；Flabellum
521 are fixed on fan board 520 by bolt 522, and flabellum 521, fan board 520 can be along with axle journals
510 and pump shaft 50 together rotate, and produce axial cross-ventilation, thus the air-flow producing circulation taken away
Heat in bearing block 100.
Fan guard 530 is a cylindrical structure, and it is peripheral that it is located at flabellum 521, is used for guaranteeing flabellum 521
The air-flow produced flows downward, guard block safety simultaneously；Between this fan guard 530 and bearing block 100
Cooperatively forming vent 30, air-flow flows out from this vent 30 and takes away heat.
As shown in Figure 2, Figure 3 and Figure 4, the sidewall of bearing block 100 is provided with some fin 102,
In the present embodiment, these fin 102 are perpendicular to the sidewall of bearing block 100, and uniform at circumferencial direction
Distribution；The bottom surface 120 of bearing block 100 also is provided with fin 101, these fin 101 and bottom surface 120
Vertically, and in a circumferential direction it is uniformly distributed；Fin 101,102 is used to coordinate flabellum 521, side
Bearing block 100 is helped to dispel the heat.
When the present invention works, before pump machine starts, in oil pocket 110, first inject lubricating oil to indicating quarter
Degree 35, now the 1/2 of lower thrust-bearing 550 is immersed in lubricating oil；Now pump machine starts, pump shaft 50
High speed rotating, the lubricating oil in oil pocket 110 is got rid of the journal bearing 540 to top by axle journal 510, it is achieved
Splash lubrication to journal bearing 540；Flabellum 521 rotates along with axle journal 510, pump shaft 50, and produces
Downward axial flow, takes away journal bearing 540, the heat of lower thrust-bearing 550, and temperature is higher
Air-flow subsequently from vent 30 to spilling out.
Newly using due to this practicality and be mounted directly flabellum 521 above bearing cap 300, flabellum 521 can be straight
Connect and rotate with pump shaft 50, efficiently utilize the existing structure of bearing, compact conformation, take volume little；
Directly producing air-flow, and the fin 101,102 of the most helpful heat radiation above bearing, refrigeration is good
Good, it is easy to promote.
Furthermore, owing to taking seamless steel pipe to make oil sealing bucket 51 and at its leave from office terrace 53 and bearing block
It is additionally provided with O RunddichtringO 52 between the bottom surface 120 of 100 and can effectively prevent oil leakage.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, the present invention is not restricted to the described embodiments, above-described embodiment and explanation
