Abstract
The invention discloses an elliptic bearing capable of being subjected to forced cooling. The elliptic bearing comprises an upper bushing cover, an upper bushing body, a lower bushing cover and a lower bushing body; the upper bushing cover is arranged on the upper bushing body in a sleeving manner for forming an upper-half bearing part; the lower bushing cover is arranged on the lower bushing body in a sleeving manner for forming a lower-half bearing part; the upper-half bearing part and the lower-half bearing part are combined to form the elliptic bearing; and a bearing liner is arranged on an inner ring of the elliptic bearing. The elliptic bearing is characterized in that a plurality of cooling oil holes parallel to the bearing axis are formed in the lower bushing body nearby the bearing liner of the elliptic bearing. During normal operation of the elliptic bearing, by leading cooling oil into the cooling oil holes, cooling oil passes by the bearing liner unceasingly, then heat in the bearing liner is taken away, the temperature of the bearing liner is reduced, and the forced cooling on the elliptic bearing is realized.
Description
Technical field
The present invention relates to large-scale generating equipment, specifically a kind of elliptic bearing that can force to cool down.
Background technology
With the continuous improvement of generating set power, rotor is more and more weighed, the load of sliding bearing also more and more higher, especially
It is elliptic bearing, the temperature of tile fragment is very high.Despite the use of many lubrication means, but effect on driving birds is not good, have impact on the use of bearing
In the life-span, improve the operation risk of rotating machinery.
The content of the invention
The invention aims to solve above-mentioned technical problem, there is provided a kind of elliptic bearing that can force to cool down,
Realization the technical scheme is that：A kind of elliptic bearing that can force to cool down, including upper watt set, Shang watt body, lower watt
Set, lower watt of body；It is described Shang watt be enclosed within watt body composition bearing upper half, described lower watt is enclosed within lower watt of body under composition bearing
Half；The bearing is upper and lower to be partly combined into elliptic bearing, and its inner ring has jewel；It is characterized in that：In the jewel of elliptic bearing
On lower watt of neighbouring body, there is the cooling oilhole that several are parallel with bearing axis.
The cooling oil nose end head has the gear oil cap plate for making cooling oilhole communicating together.
The gear oil cap plate is arranged on lower watt of body both sides end face, has some cooling oil Oil Guide chambers thereon, the cooling oil Oil Guide
Correspondence adjacent cooling oilhole in chamber is one group, follow-up continuous cold into the next one to make cooling oil that oilhole is cooled down at by one
But oilhole is until final discharge from bearing.
The end face of the lower watt of body is equipped with inclined hole insertion to watt body fuel feed hole, so as to draw cooling oil to cooling down oilhole.
The jewel is coal face.
The invention has the beneficial effects as follows：
When the bearing normally runs, by cooling oil is introduced cooling oilhole, coal spherical bearing lining nearby constantly will have
Cooling oil flows through, and so as to take away the heat of coal, reduces bearing liner temperature, realizes that the pressure to elliptic bearing is cooled down.

Specific embodiment
As shown in Figure 1 to Figure 4, a kind of elliptic bearing that can force to cool down, including upper watt set 1, Shang watt body 2, lower watt cover 3, under
Watt body 4；The Shang watt set 1 is enclosed within watt body 2, and the lower watt of set 3 is enclosed within lower watt of body 4, is then combined into elliptic bearing, its
Inner ring has coal face 5；On lower watt of body 4 near the coal face 5 of elliptic bearing, there is the cooling oil that several are parallel with bearing axis
Hole 8.There is the gear oil cap plate 13 for making cooling oilhole 8 communicating together 8 termination of the cooling oilhole, is fixed through nut bore 11 with screw
In lower watt of 4 end face of body.There are some cooling oil Oil Guide chambers 10 on the gear oil cap plate 13, the cooling oil Oil Guide chamber 10 makes adjacent cold
But 8 UNICOM of oilhole, cools down oilhole 8 until most to make cooling oil that the next one is gone successively to after cooling down oilhole 8 at by one
Whole Jing cooling oils outlet 12 is discharged from bearing.The end face of the lower watt of body 4 is equipped with 7 insertion of cooling oil oil guiding hole to a watt body and enters
Oilhole 6, described watt of body fuel feed hole 6 and watt 9 UNICOM of set fuel feed hole, such that it is able to the cooling oil that will be introduced by watt set fuel feed hole 9
Deliver to cooling oilhole 8.
When the bearing normally runs, by cooling oil is introduced cooling oilhole 8, coal face 5 nearby constantly will have
Cooling oil flows through, and so as to take away the heat of coal, reduces bearing liner temperature, realizes that the pressure to elliptic bearing is cooled down.
Use above specific case is illustrated to the present invention, is only intended to help and is understood the present invention, not to limit
The system present invention.For those skilled in the art, according to the thought of the present invention, can also make some simple
Deduce, deform or replace.
