This utility model embodiment discloses a kind of coupling shield, to efficiently solve centrifugal compressor units driving shaft
The problem that place's leakage of oil is splashed.
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to the structural representation of the coupling shield that Fig. 1-Fig. 2, Fig. 1 provide for this utility model embodiment；Fig. 2 is
The latter half structural representation of the coupling shield that this utility model embodiment provides.
In a kind of specific embodiment, present embodiments provide a kind of coupling shield, mainly shaft coupling is played protection
Effect, on the one hand prevent staff from touching unintentionally the shaft coupling of high-speed rotation, on the other hand prevent external object pair
The shock of shaft coupling.
This coupling shield includes shroud body 1, and wherein shroud body 1 refers to shaft coupling can rise primary protection work
Parts, i.e. by being set in the outside of shaft coupling to protect shaft coupling, wherein the concrete structure of shroud body 1 can
With with reference to prior art.Wherein shroud body 1 can use plastic housing and iron-clad, but preferably shroud body 1 is aluminum cover herein
Shell body, because aluminum material can be effectively prevented from the generation of spark, it is adaptable to explosion-proof environment, and intensity is higher.
In the present embodiment, one end of shroud body 1 is provided with the connection dish 2 for being connected with power axle bed, to stop
Oil on line shaft arbitrarily splashes, in order to have more preferable oil resistance effect, and the preferably company of sealing between connection dish 2 and power axle bed
Connecing, wherein connection dish 2 can use sealing welding, it would however also be possible to employ bolt connects, and arranges sealing ring.Wherein need explanation
It is that shaft coupling is generally connected to main shaft i.e. between line shaft and driven shaft, and the support of line shaft is by line shaft seat supports
, such as centrifugal compressor units, this line shaft is centrifuge principal axis, and power axle bed refers to centrifugal support.Shroud body 1
Be provided with the connection dish 2 being connected with power axle bed, then this end should refer to the one end near power axle bed, and the other end then should
Extend to the other end of shaft coupling, i.e. extend to the end of driven shaft, it is also possible to extend directly on driven axle bed.At case originally
The bottom of body 1 is provided with oil-out, so that the flowing materials such as the lubricating oil within shroud body 1 can be discharged by oil-out.
Reclaim leakage of oil for convenience, it is also possible to the lower end of oil-out is provided with oil return pipe.Above-mentioned connection dish 2 can be with shroud body
1 is one-body molded, it is possible to so that connection dish 2 is connected with shroud body 1 bolt.
When applying this coupling shield, after ensureing that shroud body 1 is located on shaft coupling, connection dish 2 is connected to
On power axle bed, such as centrifugal compressor units, connection dish 2 is connected on centrifugal support.In life-time service, meeting in power axle bed
There is lubricating oil along main shaft outwardly, and under the high-speed rotation of line shaft, lubricating oil can splash away, because shroud body
The connection dish 2 of 1 is connected with power axle bed, so that shroud body 1 is effectively extending on power axle bed, and the lubrication now sputtered
Oil can be splashed to inside shroud body 1, to be prevented from flowing further.Again because the bottom of shroud body 1 is provided with fuel-displaced
Mouthful, make the oil inside shroud body 1 can pass through oil-out stream, so by this coupling shield, can make to fly on line shaft
The oil spattered is pooled at oil-out rather than arbitrarily splash, and wherein shroud body 1 plays the effect of gear oil.So this shaft coupling
Guard shield can efficiently solve the problem that at centrifugal compressor units driving shaft, leakage of oil is splashed.
Casing base is provided with oil-out, simultaneously it should be guaranteed that, be positioned at and be splashed on shroud body 1 medial surface
Oil should trickle to oil-out, and this oil could flow out from oil-out then.Simultaneously in order to make lubricating oil flow to as soon as possible
Hydraulic fluid port, can be provided with inwardly protruded oil baffle 3 in the inside bottom of shroud body 1, this oil baffle 3 inwardly protruding for
By the lubrication oil catch of splashing to oil-out.And distance between the inner face of oil baffle 3 and driving shaft is the smaller the better.In view of main
Rotational axis direction is generally a direction, it is possible to oil baffle 3 is arranged on the side of oil-out, and when mounted, makes gear
Oiled-plate method 3 is by oil side near the side of oil-out.After making oil splash on oil baffle 3, fly to during splash near oil-out as far as possible
Place.The inner deflection oil-out bending of oil baffle 3, wherein inner one end referring to close driving shaft axis can be made.
Typically arbitrarily splashing in order to avoid oil, the inner chamber of shroud body 1 seals setting the most as far as possible.When bottom accumulates oil relatively
Time many, now shroud body 1 content is easily formed negative pressure, and under atmospheric pressure, oil is difficult to flow out from oil-out again.Based on
This, can arrange venthole, and venthole is the smaller the better in the upper end of shroud body 1, but too small, ventilates the most smooth.
In view of resource scarcity and environmental protection, typically the lubricating oil that oil-out flows out can be reclaimed, in order to reclaim conveniently,
Should avoid polluting as far as possible, in order to be effectively prevented from polluting, at passage, the most preferably be provided with air filter 4, empty
Air cleaner 4 is the device that the contaminant filter in a kind of air that can will pass through falls, to avoid impurity to enter into shroud body 1
Inside, the concrete structure of air filter 4 is referred to prior art.
Because extending at power axle bed, so this coupling shield is the longest.Install for convenience, shroud body can be made
1 includes lower house 11 and upper casing group bolted with lower house 11, and wherein lower house 11 should be integral piece, to avoid seam crossing
Leakage of oil.Wherein upper casing group can include multiple upper shell 12 being set up in parallel the most successively, is preferably provided with two upper casings
Body 12.Multiple upper shell 12 is set, it is simple to arrange manufacture, and when monitoring shaft coupling, it is not necessary to by whole for whole upper casing group
Remove.In order to ensure sealing effectiveness, the most preferably sealing strip is set between upper shell 12 and lower house 11, simultaneously two adjacent
Upper shell 12 between it is also preferred that arrange sealing gasket.In order to ensure bulk strength, the most preferably two upper shell 12 bolts connect.
Shroud body 1 overall can use tubular type, and one end of shroud body 1 connects connection dish 2, and the other end, i.e.
One end away from connection dish 2 should extend at driven shaft, to cover shaft coupling.The diameter of shaft coupling is the biggest, institute
With the cross section of the lumenal cross-section of shroud body 1 driven shaft to be significantly greater than, in order to effectively protect shaft coupling from side
Device, the most preferably in shroud body 1, end away from connection dish 2 is provided with the annular protrusion 13, Jin Erneng extended internally
Enough play shaft coupling is wrapped up effectively.
Based on the coupling shield provided in above-described embodiment, this utility model additionally provides a kind of centrifugal compressor
Group, this centrifugal compressor units includes any one coupling shield in above-described embodiment, the connection dish of described coupling shield
It is connected with the centrifuge axle head of centrifugal compressor units.The shaft coupling in above-described embodiment is have employed due to this centrifugal compressor units
Device guard shield, so the beneficial effect of this centrifugal compressor units refer to above-described embodiment.
