The presence or addition of individual other elements or its combination.
As shown in figures 1 and 3, the utility model provides a kind of bearing seal structure for rotating machinery, and it includes：
Bearing 100, it is arranged on the main shaft 200 for rotating machinery；
End cover 300, the end that it is arranged on bearing 100 is with fixation and seals the bearing 100；
Rotating ring 400, it is arranged on the main shaft 200 between the bearing 100 and the end cover 300, with the master
The tight fit of axle 200, the axially external of the rotating ring 400 in axial direction extends outward knuckle 401；
And stationary ring 500, it is set on the main shaft 200 and is fixedly attached to the end cover 300, the stationary ring
Be provided with annular groove 501 on 500 outer peripheral face, the axially inner side wall 502 and the rotating ring 400 of the annular groove 501 it
Between define axial gap 503；The knuckle 401 of the rotating ring blocks the axial gap 503 and at least part of annular groove 501
Opening.The rotating ring 400 is rotated with the main shaft 200, and the lubricating oil adhered on the main shaft 200 is rotated,
So that lubricating oil is cast aside on the inwall of the end cover 300 along rotating ring vertical plane under the action of the centrifugal force；The knuckle 401 hides
The axial gap 503 is kept off, so as to avoid lubricating oil from being dropped in the axial gap 503, then along stationary ring 500 and main shaft
200 clearance leakage is out.The knuckle 401 is also configured to block at least part of stationary ring 500, is forming the same of sealing
When, it is to avoid the oil droplet fallen into the stationary ring 500 enters the axial gap 503 under the influence of centrifugal force, will can also moisten
Lubricating oil oil droplet is guided to the madial wall of the end cover 300, for entering bearing housing bottom by drainback passage.
Wherein in one embodiment, as shown in Fig. 2 the rotating ring 400 and the interference fit of the main shaft 200.It is described dynamic
The knuckle 401 on ring 400 is arranged on the end of the periphery surface side 402 of the rotating ring 400.The knuckle 401 is formed at institute
State on the axially external face 403 of rotating ring 400.Thus, when the lubricating oil being attached on the main shaft 200 under the action of the centrifugal force,
Cast aside along the axially inner side face of rotating ring 400, the effect of the knuckle 401 is to coordinate the stationary ring 500 to be formed to the bearing
100 sealing, while avoiding oil droplet from falling into the axial gap 503.
Wherein in one embodiment, as shown in figure 1, the end of the axially inner side wall 502 of the annular groove 501 is to institute
That states annular groove 501 internally extends lip 504.The effect of the lip 504 is to prevent from being collected to the annular groove 501
Interior lubricating oil falls into the axial gap 503 again under the action of the centrifugal force, causes oil leak.
Wherein in one embodiment, the stationary ring 500 is bolted on the end cover 300 (in figure not
Show), the axially outer side of the annular groove 501 connects the end cover 300.
Wherein in one embodiment, as shown in figure 1, the stationary ring 500 is formed in one with the end cover 300,
The stationary ring 500 is radially gone up to extend to main shaft 200 and is formed for the end cover 300.In process, it is described close
The axially outer side for blocking lid 300 extends inwardly to the outer peripheral face of main shaft 200 in radial directions, then again in axial direction to
It is interior extend simultaneously keep the axial gap 503 with the rotating ring 400, afterwards radially on extend out to the knuckle
After 401, inside bending forms the lip 504.The stationary ring 500 is integrally formed with the end cover 300 and is more beneficial for axle
The sealing held.
Wherein in one embodiment, as shown in figure 1, the bearing seal structure for rotating machinery also includes：Baffle plate
600, it is arranged on the axial inwall of the end cover 300, and footpath is provided between the baffle plate 600 and the rotating ring 400
To gap；The radial clearance alters the big 2mm of axle amount than the maximum radial for rotating machinery permission.The freedom of the baffle plate 600
End near the outer peripheral face of the rotating ring 400, is ensureing the premise that the rotating ring 400 is rotated with the main shaft 200 to greatest extent
Under, the lubricating oil oil droplet that stop portions are cast aside from the main shaft flies out outside the rotating ring 400, causes leakage.
Wherein in one embodiment, as shown in figure 1, the bearing seal structure for rotating machinery also includes：Bearing housing
700, it is arranged on the outer ring of the bearing 100, and the end cover 300 is for example bolted to connection the bearing housing
700.The bearing housing 700 is used within the fixing seal of the bearing 100 to the end cover 300 and bearing housing 700.
Wherein in one embodiment, as shown in figure 1, drainback passage 301 is offered on the end cover 300, by institute
The lubrication oil droplet for stating the attachment of 300 inwalls collects and is drained to the bottom of the bearing housing 700.When lubricating oil is thrown under the action of the centrifugal force
During from the extremely madial wall of the end cover 300, the drainback passage 301 can in time guide oil droplet to flow to the bearing housing
700 bottoms, it is to avoid lubrication buildup causes leakage in the stationary ring 500.
Wherein in one embodiment, as shown in figure 1, the knuckle is 90 °, the axial length of the knuckle is more than described
Axial gap 2mm.During assembling, reserved enough axial gap is needed between the rotating ring 400 and the stationary ring 500, to ensure
State freely rotating for rotating ring 400.The axial gap 503 alters the big 2mm of axle amount than the maximum that the rotating machinery is allowed.The folding
The length of angle 401 must determine according to the width of the axial gap 503, and one is embodiment wherein, the knuckle 401
Length 2mm bigger than the width of the axial gap.
Wherein in one embodiment, the rotating ring 400 and the stationary ring 500 are steel part material.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and implementation method
Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new and shown here as the legend with description.
