Description
Technical field
The invention belongs to air bearing technology fields, and in particular to a kind of air hydrodynamic foil bearing paillon of cylinder pin type
Fixed structure.
Background technique
Bearing is an extremely important part in modern machinery and equipment, wide range of applications, from small-sized household electricity
Device has the presence of bearing to ship, aerospace.Component of the bearing as a core, but limits always other technologies
Development.Gas dynamic pressure paillon transverse bearing relative to other bearings have working speed is high, friction energy loss is small, long service life and
The advantages that operating ambient temperature range is wide.But the flat paillon and corrugated foil in air transverse bearing are in the process of shaft start and stop
In can wear, after multiple start and stop, flat paillon or corrugated foil serious wear will lead to bearing performance decline or even can not
Success " taking off ", it is therefore desirable to the bearing more renewed.And traditional air transverse bearing by the way of welding by flat paillon and
Corrugated foil is fixed on bearing holder (housing, cover), and this mode is more troublesome when not only installation, but also once flat paillon or corrugated foil
Piece is seriously worn, and entire bearing will be all replaced, therefore traditional method is not only time-consuming but also increases cost.
The present invention is to design a both ends on bearing holder (housing, cover) to be embedded in the cylinder groove of straight pin, by using straight pin come
Achieve the purpose that fixed flat paillon and corrugated foil.Once flat paillon or corrugated foil are worn, straight pin only need to be removed more
Flat paillon or corrugated foil are changed, without re-working entire bearing holder (housing, cover), this mode is not only saved the time, but also is saved significantly
Cost is saved.
Summary of the invention
To solve the above-mentioned problems, facilitate the installation and replacement of flat paillon or corrugated foil in air transverse bearing, this hair
It is bright to provide a kind of air hydrodynamic foil bearing paillon fixed structure of cylinder pin type, pass through this easily flat paillon or ripple
The recycling to bearing holder (housing, cover) may be implemented in paillon substitute mode.
Technical solution of the present invention:
A kind of air hydrodynamic foil bearing paillon fixed structure of cylinder pin type, including bearing holder (housing, cover) 1, corrugated foil 2, flat foil
Piece 3, straight pin a4 and straight pin b5；
The bearing holder (housing, cover) 1 is hollow circuit cylinder cylinder, and inner wall is equipped with cuboid slot 6, in cuboid slot 6 and bearing holder (housing, cover) 1
Wall surface is connected, and is open state；The bearing holder (housing, cover) 1 is provided with cylinder groove 7 in wall body, and the diameter dimension of cylinder groove 7 is small
In the depth of cuboid slot 6；Along the cross section direction of cylinder groove 7, the middle part of cylinder groove 7 and cuboid slot 6 there are crossover sites,
It is connected to cylinder groove 7 with cuboid slot 6；The both ends of cylinder groove 7 are open state, for installing straight pin a4 and straight pin b5；
The cuboid slot 6 and cylinder groove 7, is parallel to each other with the central axes of bearing holder (housing, cover) 1, cuboid slot 6 and cylinder groove 7 and corrugated foil
The peaceful paillon dog-ear 9 of piece dog-ear 8 cooperates；
The corrugated foil 2 is circumferential not closed hollow circuit cylinder barrel structure, and surface has and cylindrical drum center line phase
Parallel ripple, circumferential not closed one end are foldable outwardly corrugated paillon dog-ear 8；The size of the corrugated foil 2 is less than
The size of bearing holder (housing, cover) 1；The flat paillon 3 is circumferential not closed hollow circuit cylinder barrel structure, is by a rectangular paillon through it
Two opposite side doublings are around forming, and the junction of two opposite side is open state, and wherein a line is foldable outwardly to form flat paillon
Dog-ear 9；The size of the flat paillon 3 is less than the size of corrugated foil 2, and corrugated foil 2 is placed in the inside of bearing holder (housing, cover) 1, wave
2 outer surface of line paillon is bonded with 1 inner surface of bearing holder (housing, cover), and flat paillon 3 is placed in the inside of corrugated foil 2, the outer surface of flat paillon 3
Be bonded with the inner surface of corrugated foil 2, the peaceful paillon dog-ear 9 of corrugated foil dog-ear 8 is inserted into cuboid slot 6, straight pin a4 and
Straight pin b5 is embedded into cylinder groove 7 from the both ends of cylinder groove 7 respectively, so that the peaceful paillon 3 of corrugated foil 2 is fixed on bearing
In set 1.
Beneficial effects of the present invention:
The present invention and traditional radial gas dynamic pressure foil bearing in the mode of the flat paillon of fixation and corrugated foil
Difference, traditional air transverse bearing are mounted on flat paillon and corrugated foil on bearing holder (housing, cover) by the way of welding, both wasted
Time increases cost again.The present invention is the cylinder groove for designing a both ends on bearing holder (housing, cover) and being embedded in straight pin, passes through benefit
Achieve the purpose that fixed flat paillon and corrugated foil with straight pin.Once flat paillon or corrugated foil are worn, need to only take
Lower cylindrical pin replaces flat paillon or corrugated foil, and without re-working entire bearing holder (housing, cover), this mode not only saves the time,
And cost is greatly saved.

Specific embodiment
Below in conjunction with attached drawing and technical solution, a specific embodiment of the invention is further illustrated.
Such as Fig. 1, a kind of air hydrodynamic foil bearing paillon fixed structure of cylinder pin type, including bearing holder (housing, cover) 1, corrugated foil
2, flat paillon 3, straight pin a4 and straight pin b5；Wherein, one " frame " of the structure as a whole of bearing holder (housing, cover) 1 is set on inner wall
There is cuboid slot 6, a cylinder groove 7 is provided in wall body, the diameter dimension of cylinder groove 7 is less than the depth of cuboid slot 6；Along cylinder
There are crossover sites at the middle part of the cross section direction of slot 7, cylinder groove 7 and cuboid slot 6, connect cylinder groove 7 and cuboid slot 6
It is logical；The structural schematic diagram of bearing holder (housing, cover) 1 and the partial enlarged view of structural schematic diagram are as shown in Figures 2 and 3.
Fig. 4 is the structural schematic diagram before corrugated foil 2 assembles, and corrugated foil 2 is circumferential not closed hollow circuit cylinder cylinder knot
There is the ripple parallel with cylindrical drum center line on structure, surface, and circumferential not closed one end is foldable outwardly corrugated paillon dog-ear
8, dog-ear length is several millimeters and differs, depending on bearing specific size；Fig. 5 is the structural schematic diagram before the assembly of flat paillon 3, is put down
Paillon 3 is not closed " cylindrical drum " of a circumferential direction, and wherein one end to form prominent to being folded outward, and referred to as flat paillon dog-ear 9, dog-ear is long
Degree differs for several millimeters, depending on bearing specific size.
The peaceful paillon dog-ear 9 of corrugated foil dog-ear 8 is installed into the cuboid slot 6 and cylinder groove 7 of bearing holder (housing, cover) 1, corrugated foil
The outer surface of piece 2 is bonded with the inner surface of bearing holder (housing, cover) 1, and the outer surface of flat paillon 3 is bonded with the inner surface of corrugated foil 2.Cylinder
Pin a4 and straight pin b5 is universal standard part, and length is not more than the half of 1 length of bearing holder (housing, cover), and straight pin a4 and straight pin b5 divide
It is not embedded into cylinder groove 7 from the both ends of cylinder groove 7 to fix the peaceful paillon 3 of corrugated foil 2, straight pin is not outer after being completely embedded into
Dew.The partial enlarged view of effect picture and assembly effect picture after assembly is as shown in Figure 7 and Figure 8.The peaceful paillon of corrugated foil dog-ear 8
Dog-ear 9 is deformed by the extruding of straight pin a4 and straight pin b5, such as Fig. 9 and Figure 10 after the peaceful paillon 3 of corrugated foil 2 deforms
