Description
Technical field
The present invention relates to a kind of bearing cooler, more particularly to a kind of high temperature sliding bearing cooling device.
Background technology
In the production process of power plant and large enterprise, motor is main power source (such as various water pumps, blower fan
Machinery), it once breaks down, and is sizable, especially large and medium-sized high-voltage electric to loss caused by whole production
Machine, whole production process can be seriously affected.The sliding bearing of motor is in long-term and run at high speed, and will produce big calorimetric
Amount, has a strong impact on its operation.In large and medium-sized high-tension motor, electrical fault caused by due to bearing running hot damage, it account for
More than the 70% of motor whole failure, especially particularly evident in summer performance, bearing running hot is to perplex operating maintenance always
A great problem.
The type of cooling of the medium-sized high pressure bearing of motor of prior art is natural cooling, cooling effect extreme difference, bearing shell warp
The often scaling loss because of overheat, and bearing shell crosses cause thermal damage will have a strong impact on whole production process, and considerable damage is brought to production,
The bearing of motor of large and medium-sized high-tension motor is costly simultaneously, and mounting process is more complicated during replacing, safeguards and changes meeting again
Put into the waste of larger manpower and other materials.
A kind of sliding bearing cooling dress is disclosed in the Chinese utility model patent that Application No. 201320774478.0
Put, bearing cooler is arranged in the grease chamber of sliding bearing housing by this improved method, using the heat-exchange method of physics by axle
Hold caused heat during running at high speed to radiate by cooler, cost is relatively low, radiating effect is preferable, to a certain extent has
Beneficial to saving maintenance cost；It is cold that a kind of bearing is disclosed in the Chinese utility model patent that Application No. 201520941383.2
But device, solve the existing bearing on the inside of the bearing chamber caused by old oil can not discharge caused by make motor bearings temperature
Rise, bearing film is destroyed, damage bearing, the problem of causing unit load to decline.But two kinds of bearings in above-mentioned patent are cold
But the improvement of device is all not involved with is changed to bearing arrangement, and bearing temperature is reduced by being passed through high pressure cold air
Method.
For above-mentioned defect, the present inventor has invented a kind of high temperature sliding bearing cooling device, by original
On the basis of sliding bearing structure, passage and air channel are added, is passed through high pressure cold air to reduce the method for bearing bush temperature, no
It is only simple in construction, easy to process, can with it is simple and effective reduction bearing bush temperature, increase economic efficiency, can also be to a certain degree
The upper waste for reducing manpower and other materials.
The content of the invention
In order to solve the above problems, the invention provides a kind of high temperature sliding bearing cooling device.By improving sliding axle
The structure held, passage and air channel are added, high pressure cold air is passed through to reduce the method for bearing temperature, extends the work of bearing
Make the life-span, improve economic benefit to a certain extent, while also reduce the waste of manpower and other materials.
Technical scheme is used by realizing above-mentioned purpose：
1st, the high temperature sliding bearing cooling device is mainly by axle sleeve (1), front shroud (2), bearing block (3), bearing shell (4), after
Cover plate (5), lubricating cup hole a, lubricant b, air admission hole (6), venthole (7), ventilation ring (8) and the part composition of link slot (9) ten,
It is mainly characterized by：To avoid the dry friction between axle sleeve (1) and bearing shell (4), there are between axle sleeve (1) and bearing shell (4)
The lubricant b of lubrication, lubricating oil enter through lubricating cup hole a, are lubricated；Front shroud (2) and back shroud (5) can be effective
Oil leak is prevented, so as to avoid the operating efficiency of whole device from being affected；The air admission hole (6) of conveying high-pressure cold air and
Venthole (7) is located on bearing block (3), there is the ventilation ring (8) of two certain lengths between bearing block (3) and bearing shell (4), high
Press cold air to enter through air admission hole (6), flow through ventilation ring (8), after cooling to device, flowed out from venthole (7).
2nd, the ventilation ring (8) of the high temperature sliding bearing cooling device is located at lubricating cup hole a both sides respectively, between two ventilation rings
Connected through link slot (9), high pressure cold air enters through air admission hole (6), after the ventilation ring for flowing through left side, is transported by link slot (9)
Move the ventilation ring to right side, take away the heat of bearing shell (4), flowed out from venthole (7).
3rd, the high temperature sliding bearing cooling device is simple in construction, easy to process, it is contemplated that support to axle and bears on axle
The factors such as the load of part, air admission hole (6), venthole (7), the diameter of ventilation ring (8) and link slot (9) are unsuitable excessive,
When diameter is excessive, the load-carrying properties of bearing can be affected, therefore in general, air admission hole (6), the aperture of venthole (7)
For 0.25 times of half bearing thickness, the aperture of link slot (9) is 0.3 times of half bearing thickness, the length of the ventilation ring (8) of lubricating cup hole a both sides
It is 0.25 times of half bearing thickness for 0.35 times of bearing shell length, thickness.
According to above-mentioned steps, a kind of high temperature sliding bearing cooling device can be obtained.
The primary structure of high temperature sliding bearing cooling device is determined by the above method, mainly by axle sleeve (1), front shroud
(2), bearing block (3), bearing shell (4), back shroud (5), lubricating cup hole a, lubricant b, air admission hole (6), venthole (7), ventilation ring (8)
With the part composition of link slot (9) ten, it is mainly characterized by：On the basis of original high temperature slides axle construction, high pressure with the addition of
Cold air transfer passage reduces bearing bush temperature, can effectively solve the problems, such as bearing running hot, extends the service life of bearing, and
The apparatus structure is simple, there is certain economy.
