Description
Technical field
The utility model is related to the accessories on bearing block.
Background technology
High-speed rotating bearing usually requires to be cooled down, and a kind of type of cooling is the cooling cycle by lubricating oil to axis
Bearing is cooled down.In the prior art, for by the cooling bearing of lubricating oil, usually to bearing block closure designs, and it is anti-with this
Only lubricating oil does not flow out bearing block.But hydronic lubricating oil needs high-pressure oil pump that lubricating oil after cooling is pumped into bearing block
It is interior, high pressure conditions are in the bearing block of sealing, under the high pressure conditions of bearing block, lubricating oil passes through line shaft and bearing seat-box
Gap between body is easy to except outflow bearing block.Therefore, in the prior art, by the cooling cycle of lubricating oil to bearing block
It carries out under cooling mode, by preventing the oil-proof not yet of outflow of lubrication oil bearing block to the sealing of bearing block.
Invention content
Problem to be solved in the utility model：It is asked in the cooling cycle of lubricating oil since oil leak occurs in the high pressure of bearing block
Topic.
To solve the above problems, the scheme that the utility model uses is as follows：
A kind of oleophobic collar bush for bearing block oil-leakage-prevention, including ring set ontology and oil baffle ring；The ring set ontology
In circle ring column structure；Oil baffle ring is located at one end of the ring set ontology；The ring set ontology is equipped with one end of oil baffle ring
Annular the first oleophobic slot of step is equipped on the inside of annulus；Oil baffle ring is equipped with annular towards the other end for being equipped with oil baffle ring
The second oleophobic slot；The external annulus of the ring set ontology is equipped with the W-shaped oleophobic slot of annular；The W-shaped oleophobic slot is that section is in W
The groove body of shape.
Further, the external annulus of oil baffle ring is equipped with wedge angle ring body.
The technique effect of the utility model is as follows：The utility model is mounted on the axis hole of bearing block babinet, and is sleeved on dynamic
Except power axis so that blow-by inside and outside bearing block babinet, so that bearing block babinet external and internal pressure subtractive is small, by reducing axis
Pressure difference inside and outside bearing babinet, various oleophobic slots designs on the oleophobic collar bush in conjunction with the utility model so that through bearing block
The lubricating oil that babinet axis hole overflows is dredged to various oleophobic slots, then dredges oleophobic slot to the oil spilling room in bearing block babinet
To avoid Leakage.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model embodiment.
Fig. 2 is cutting plane view of the oleophobic collar bush of the utility model embodiment after the cutting of axle center.
Fig. 3 is scheme of installation of the utility model embodiment on bearing block.
Specific implementation mode
The utility model is described in further details below in conjunction with the accompanying drawings.
A kind of oleophobic collar bush for bearing block oil-leakage-prevention is mounted in the axis hole of bearing block and uses as shown in Figure 1 and Figure 2
In bearing block oil-leakage-prevention, including ring set ontology and oil baffle ring 32.The ring set ontology of oleophobic collar bush 3 is in circle ring column structure,
The diameter of the axis hole of its outer diameter and bearing block matches, and the diameter of internal diameter and line shaft matches.The external annulus of ring set ontology
It is equipped with the W-shaped oleophobic slot 34 of annular.W-shaped oleophobic slot 34 is the groove body that section is in " W " shape.Oil baffle ring 32 is located at ring set ontology
One end, toroidal, internal diameter is identical as ring set ontology, outer diameter be more than ring set ontology outer diameter.Ring set ontology is equipped with gear
The first oleophobic of annular slot 31 of step is equipped on the inside of one end annulus of oiled-plate method ring 32.Oil baffle ring 32 has certain thickness, gear
Oiled-plate method ring 32 is equipped with the second oleophobic slot 33 of annular towards the other end for being equipped with oil baffle ring 32.The internal diameter of second oleophobic slot 33
Match with the diameter of axis hole 4, the internal diameter of the second oleophobic slot 33 is identical as the outer diameter of ring set ontology in other words.
When the oleophobic collar bush is mounted in the axis hole of bearing block, as shown in figure 3, wherein 1 is bearing block babinet,
4 be axis hole, and 3 be the oleophobic collar bush of the present embodiment.When oleophobic collar bush 3 is sleeved in the axis hole 4 of bearing block 1, oleophobic collar bush 3
On oil baffle ring 32 be located in the babinet of bearing housing.Axis hole 4 is equipped with oil guide groove of the opening towards axle center, W-shaped oleophobic slot 34
The oil guide groove, the width of W-shaped oleophobic slot 34 is less than the width of oil guide groove so that W-shaped oleophobic slot 34 is by the slot of oil guide groove both sides
Wall is enclosed in the range of Oil Guide channel opening.The lubricating oil on W-shaped oleophobic slot 34 can flow into the oil guide groove on axis hole 4 as a result,
Then it is flowed within bearing block babinet through the oil guide groove.Circular channel in oleophobic collar bush 3 is the channel for installing line shaft.It is dynamic
Power axis passes through the circular channel in oleophobic collar bush 3 to enter in the babinet of bearing housing, is connected with the bearing in the babinet of bearing housing
It connects.
Operation principle when the present embodiment is mounted in bearing block is as follows, and first, oil baffle ring 32 can block high speed and revolve
Shaft holds the lubricating oil for throwing away or splashing out.Plate face of the lubricating oil that oil baffle ring 32 is stopped through oil baffle ring 32 to flow down and
It flows back in the babinet of bearing housing.The lubricating oil that oil baffle ring 32 is stopped has on a small quantity through the seam between oleophobic collar bush and line shaft
To outside babinet, but due to the elicitation effect of the first oleophobic slot 31, these are dredged to the first oleophobic slot 31 clearance flow, and can not be flowed
Go out bearing housing.The lubricating oil that high speed rotation bearing throws away or splashes out is most of through bearing chamber interior wall, through bearing chamber interior wall and gear
Gap between oiled-plate method ring 32 flows to outside babinet, but due to the elicitation effect of the second oleophobic slot 33 and W-shaped oleophobic slot 34 so that profit
Lubricating oil can not flow out bearing housing, be dredged again to bearing housing by the second oleophobic slot 33 and W-shaped oleophobic slot 34.
In addition, for so that the lubricating oil on oil baffle ring 32 flows back to bearing housing faster.On the external annulus of oil baffle ring 32
Equipped with wedge angle ring body 321.The section of wedge angle ring body 321 is the ring body of wedge angle.
