Description
Technical field
The present invention relates to the seal arrangement field, particularly relate to a kind of powder concentrator bearing combination sealing arrangement.
Background technique
At present, known powder concentrator adopts thin oil lubricant mostly, and the sealing of transmission shaft is to adopt oil sealing to add the mode of felt ring seal.Because the central negative pressure effect that rotor causes, dust very easily enters in the oil sealing, accelerates the damage of oil sealing.Simultaneously, the dust in the oil return also can cause comprising the whole lubrication system wearing and tearing of bearing and oil pump, causes system's seepage.Maintenance needs production line all to stop production, and employs large-scale crane, not only has a strong impact on normal production, and costly.
Summary of the invention
The object of the invention is to solve the above problems, propose a kind ofly can effectively stop dust to enter lubrication system, slow down the wearing and tearing of the whole lubrication system that comprises bearing and oil pump, prevent the combination sealing arrangement of oil leakage phenomenon.
The present invention adopts following technological scheme: a kind of powder concentrator bearing combination sealing arrangement, described seal arrangement is arranged on the rotary system of powder concentrator, and described rotary system comprises transmission shaft, be fixed on anti-wearing liner on the transmission shaft, be fixed on rotating disk, bearing, bearing support on the anti-wearing liner, be installed in fixedly transparent cover, O RunddichtringO, felt collar, outside framework oil seal on the bearing support;
Wherein: described combination sealing arrangement comprises: fixedly transparent cover and rotating disk form the first sealing, be installed in anti-wearing liner and fixedly the felt collar between the transparent cover form the second sealing, be installed in anti-wearing liner and fixedly between the transparent cover opening outside framework oil seal inwardly form three seals.
In technique scheme, there is annular protrusion described fixedly transparent cover exterior edge face, and described rotating disk interior edge face has annular protrusion.
In technique scheme, described annular protrusion has two groups at least.
In technique scheme, the annular protrusion between described fixedly transparent cover and the rotating disk mates the formation labyrinth seal mutually.
In technique scheme, the gap of the labyrinth seal that forms between the described annular protrusion is between 0.5mm to 6mm.
In technique scheme, the gap of the labyrinth seal that forms between the annular protrusion is 2mm.
In technique scheme, be provided with four O RunddichtringOs, described O RunddichtringO is separately positioned on:
Be provided with one between described rotating disk and the anti-wearing liner;
Be provided with two between described anti-wearing liner and the transmission shaft;
Be provided with one between described fixedly transparent cover and the bearing support.
In technique scheme, described rotating disk and anti-wearing liner are set to one; Fixedly transparent cover and bearing support are set to one.
Can find out from structure characteristic of the present invention, the invention has the advantages that: can prevent effectively that dust from entering oil sealing, prolong the shaft seal life-span; Can prevent that dust from entering the oil return system of thin oil lubricant, slow down the whole lubrication system wearing and tearing that comprise bearing and oil pump; Prevent oil seepage.
Description of drawings
The present invention will illustrate by embodiment and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the structural representation of powder concentrator bearing combination sealing arrangement of the present invention;
Wherein: the 1st, transmission shaft 2 is that bearing support 3 is that bearing 4 is that locking nut 5 is that anti-wearing liner 6, O RunddichtringO 8 are that outside framework oil seal 9 is that fixedly transparent cover 10 is that rotating disk 11 is felt collars.
Embodiment
The present invention is described further below in conjunction with accompanying drawing.
As described in Figure 1, powder concentrator bearing combination sealing arrangement of the present invention, it is located on the powder concentrator rotary system, and rotary system comprises transmission shaft 1, is fixed on anti-wearing liner 5, bearing support 2 and fixedly transparent cover 9, O RunddichtringO 6, rotating disk 10, felt collar 11 and outside framework oil seal 8 fixed thereon on the transmission shaft 1; Described rotating disk 10 is buckled in fixedly on the transparent cover 9, and described felt collar 11 is installed in anti-wearing liner 5 and fixedly between the transparent cover 9, and described outside framework oil seal 8 is installed in anti-wearing liner 5 and fixedly between the transparent cover 9.
Wherein, in the fixing exterior edge face of transparent cover 9 convex portion of some annulars is arranged, the interior edge face at rotating disk 10 also has some annular protrusions simultaneously, and fixedly the interior edge face of the exterior edge face of transparent cover 9 and rotating disk 10 mates together by these annular protrusions, the formation labyrinth seal; Described annular protrusion is at least more than two groups, and the labyrinth seal clearance that annular protrusion consists of can be selected arbitrarily between 0.5mm to 6mm, and most preferred gap is 2mm.So just formed the first sealing of whole seal arrangement; And felt collar 11 is as the second sealing of whole seal arrangement; Outside framework oil seal 8 is as the three seals of whole seal arrangement.
Four O RunddichtringOs 6 are installed in whole seal arrangement, are installed in respectively: between described rotating disk 10 and the anti-wearing liner 5 between one, described anti-wearing liner 5 and the transmission shaft 1 between two, described fixedly transparent cover 9 and the bearing support 2 one.
