Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of deceleration top lubricating sleeve provided by the embodiment of the utility model；
Fig. 2 is a kind of schematic cross-sectional view of deceleration top lubricating sleeve provided by the embodiment of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.It is understood that herein
Described specific embodiment is used only for explaining the utility model, rather than the restriction to the utility model.It further needs exist for
It is bright, part relevant to the utility model is illustrated only for ease of description, in attached drawing rather than entire infrastructure.
It should be noted that the technical program is mainly for the deceleration top for being not installed with mushroom head in the prior art,
After wheel passes through deceleration top, deceleration top lubricating sleeve is popped up in order to prevent, is improved to deceleration top lubricating sleeve, detailed content
See below the description in embodiment.
Fig. 1 is a kind of structural schematic diagram of deceleration top lubricating sleeve provided by the embodiment of the utility model, deceleration top lubrication
Set can be two or more physical entities and constitute, and is also possible to a physical entity and constitutes.
With reference to Fig. 1, which is specifically included: polyurethane filter foam circle 1, outer ring 2, wire loop 3, stainless steel
Band 4 and bail wire 5；
Wherein, polyurethane filter foam circle 1 and wire loop 3 are embedded in outer ring 2, and outer ring 2 is covered on 6 surface of cylinder body；
Bail wire 5 is connect with wire loop 3 and stainless steel band 4 respectively；Stainless steel band 4 is fixed on 7 surface of speed-reduction top housing；
Stainless steel band 4 is used to bail wire 5 being fixed on speed-reduction top housing 7；
When wheel spreading, the lubricating oil in polyurethane filter foam circle 1 is applied to 6 surface of cylinder body, so that cylinder body 6
Has oil film in surface；When wheel pass through after, bail wire 5 control outer ring 2 be fixed on 6 surface of cylinder body, prevent outer ring 2 because
Elastic force pops up cylinder body 6.
It is placed at track it should be noted that Fig. 1 shows one, and the deceleration top of lubricating sleeve is installed.
Since wire loop 3 is embedded in outer ring 2, user can not observe its internal wire loop 3 from the surface of deceleration top, in Fig. 1
The structure of wire loop 3 shown in dotted line.
In embodiment, outer ring 2 is sewed by elastic cloth.In the actual operation process, the sewing mode of outer ring 2 can
By artificial sewn by hand, can also be sewed by sewing kit.Meanwhile polyurethane filter bubble is embedded in outer ring 2
Foam circle 1 and wire loop 3.Wherein, polyurethane filter foam circle 1 can use high-density sponge, to guarantee to deposit inside it
More lubricating oil are contained, extend deceleration top lubricating sleeve uses the time.
It should be noted that before using deceleration top lubricating sleeve, it need to be first by the deceleration top lubricating sleeve in lubricating oil
Middle immersion, and it is mounted on 6 surface of cylinder body.Since deceleration top lubricating sleeve is a hollow circle, in the actual operation process, need
Deceleration top lubricating sleeve is covered in cylinder body 6.Wherein, lubricating oil is antiwear hydraulic oil.For example, the number of antiwear hydraulic oil can be
ISO-L-HM46, or No. 8 instrument oils or Number 10 aviation hydraulic oil, wherein L is hydraulic oil classification, and HM is hydraulic oil
Kind, 46 be the hydraulic oil trade mark.It is of course also possible to use other lubricating oil, as long as the very useful oil that slows down, not to this
It is defined.
In the installation for completing deceleration top lubricating sleeve, when there is wheel by simultaneously spreading deceleration top, polyurethane filter foam circle 1
Because lubricating oil included in itself being squeezed out, and be applied to 6 surface of cylinder body, so that 6 surface of cylinder body is attached by gravity
There is oil film, quickly remove 6 surface and oil contaminant of cylinder body, play the purpose of lubrication, ensure that the normal opening speed of deceleration top, improves
The brake force of deceleration top, and reduce the oiling number of field operation, Window time is shortened, labor intensity is alleviated, is mentioned
High working efficiency, while safety in production is reliably guaranteed, so that deceleration top can remain at good skill
In art state.
After wheel passes through, because polyurethane filter foam circle 1 itself has elastic force, outer ring 2 is because of polyurethane in order to prevent
The elastic force of filter foam circle 1 and pop up cylinder body 6, wire loop 3 is embedded in outer ring 1, and fix on 7 surface of speed-reduction top housing
There is stainless steel band 4, and is connect respectively with wire loop 3 and stainless steel band 4 by bail wire 5.
Fig. 2 is a kind of schematic cross-sectional view of deceleration top lubricating sleeve provided by the embodiment of the utility model.As shown in Fig. 2, steel
The first end and second end of silk fixing card 5 weld together with wire loop 3；The third end of bail wire 5 and the 4th
End is both secured to stainless steel band 4.In embodiment, the third end and the 4th end of bail wire 5 are to be similar to bending
The steel wire of crochet hook shape, and third end and the 4th end are hooked on stainless steel band 4, for fixing the position of bail wire 5
It sets.
In embodiment, the first end and second end of wire loop 3 and bail wire 5 are welded on by soldering appliance
Together, and by wire loop 3 and polyurethane filter foam circle 1 sewing in outer ring 2, then, by the third end of bail wire 5 with
And the 4th end be fixed in stainless steel band 4, wherein position of the stainless steel band 4 on speed-reduction top housing 7 can be solid according to steel wire
Surely block 5 length and the length of cylinder body 6 and adjust.Certainly, by the third end of bail wire 5 and the 4th end and not
Before rust steel band 4 is attached, the surface that stainless steel band 4 is first fixed on to speed-reduction top housing 7 is needed.
In the actual operation process, due to the equipment that deceleration top is different model, the shape of speed-reduction top housing 7 is also possible to
Different.It is to be understood that the shape of bail wire 5 is related with 7 shape of speed-reduction top housing, for example, when subtracting using A model
When the equipment of speed top, correspondingly, bail wire 5 can be A1 shape；For another example, when using the Retarder Equipments of Type B number, accordingly
, bail wire 5 can be B1 shape.
Certainly, enter dust in speed-reduction top housing 7 in order to prevent, generally dustband can be installed in speed-reduction top housing 7.
In embodiment, when wheel rolls, dustband surface and oil contaminant directly can be removed by deceleration top lubricating sleeve, reached to oil cylinder
The lubrication of body 6, while being worn caused by avoiding because of dust to 6 surface of cylinder body, to extend the service life of cylinder body.
Certainly, the deceleration top lubricating sleeve in the technical program is applicable to the Retarder Equipments of various different models, especially
It is to be used under the poor environment of harsh weather and working condition, better reflects its superior function.Illustratively, when in the winter
In the cold seasons such as it, outside air temperature can reach spends more subzero 20, and the compressed nitrogen filled in speed-reduction top housing 7 is with temperature
Decline air pressure is lower, and the lithium saponify viscosity in speed-reduction top housing 7 increases, i.e., the resistance inside speed-reduction top housing 7 increases, to prolong
The return interval of deceleration top is grown, deceleration top is reduced or done work insufficient to skating vehicle acting round；For another example, in frost day
In gas, the oil film between cylinder body 6 and speed-reduction top housing 7 is not easy to be formed, and leads to the insufficient lubrication of deceleration top, i.e., deceleration top is in vehicle
Wheel can not be bounced promptly after passing through, and reduce usage experience.
