Abstract
The invention relates to a water-cooled bearing outer cover device comprising a bearing outer cover and a cover plate, wherein the cover plate is welded on the bearing outer cover. The water-cooled bearing outer cover device is characterized in that the cover plate is provided with water inlet and outlet openings and a water tank for water circulation, the water inlet and outlet openings comprises a water inlet opening and a water outlet opening that are respectively connected with two ends of the water tank, water openings of the water inlet and outlet openings are provided with screw plugs used for a sealing purpose, and the screw plugs are connected with the water inlet and outlet openings in a threaded manner. According to the outer cover device provided in the invention, via the built-in water tank for water circulation, a rear bearing of an electric motor can be effectively cooled, a defect that a rear bearing of a conventional water-cooled electric motor cannot be cooled can be overcome, service life of the bearing can be prolonged, and long term stable operation of the electric motor can be ensured.
Description
Technical field
The present invention relates toA kind of water-cooled bearing cover apparatus, it is particularly suited for the cooling of the water-cooled machine of the underground coal mine hazardous area that explosive gas mixture exists.
Background technology
Bearing directly concerns the service life of motor as the strength member of motor, the operation conditions of bearing.And when running, the fault that Bearing Temperature causes but is innumerable, therefore reduce the temperature of bearing, the steady in a long-term operation guaranteeing motor is had very important effect.At present.Motor winding is mainly cooled down by existing water-cooled machine, and rear bearing just cannot be carried out cooling, runs once motor, and it is too high that electric motor back shaft holds temperature, easily causes " seizing ", and quickly bearing is impaired, and motor also can outlet fault.
In order to effectively water-cooled machine bearing be cooled down, guarantee the properly functioning of bearing, ensure that motor runs steadily in the long term, the needs that we cool down according to feature and the bearing of water-cooled machine, bearing end cover increases water cooling plant, effectively reduce bearing temperature, extend the service life of bearing, it is ensured that the operation steady in a long-term of motor.
Summary of the invention
It is an object of the invention to overcome water-cooled machine rear bearing temperature present in prior art too high, easily cause " seizing " and the impaired problem of bearing, it is provided thatA kind of water-cooled bearing cover apparatus, bearing temperature can be effectively reduced, extend the service life of bearing, it is ensured that the operation steady in a long-term of water-cooled machine.
For realizing above technical purpose, the technical solution used in the present invention is:A kind of water-cooled bearing cover apparatusIncluding bearing end cover and cover plate, described bridge welding is connected on bearing end cover, it is characterized in that: described cover plate is provided with intake-outlet and for water circulating water chennel, described intake-outlet includes water inlet and outlet, described water inlet is connected with the two ends of tank respectively with outlet, and the mouth of a river of intake-outlet is provided with the plug screw for sealing, and described plug screw is threaded connection with intake-outlet.
As preferably, being shaped as of described tank bends font.
As preferably, described plug screw is two.
As preferably, the material of described plug screw is pyrite.
As can be seen from the above description, the method have technical effect that: water-cooled bearing cover apparatus of the present invention the tank of water circulation can reach the purpose of cooling bearing by built-in, this cover apparatus is the build-up member of electrode, more effectively electric motor back shaft can be held and cool down, guarantee bearing life, it is ensured that the operation steady in a long-term of electrode.

Figure 1It is that the master of the present invention regardsFigure。
Figure 2It isFigure 1A-A face section viewFigure。
Attached FigureDescription of symbols: 1-bearing end cover, 2-cover plate, 3-intake-outlet, 4-plug screw, 5-tank.
Detailed description of the invention
Below in conjunction with specificallyAccompanying drawingThe invention will be further described with embodiment.
According toAccompanying drawing 1WithFigure 2Shown in,A kind of water-cooled bearing cover apparatusIncluding bearing end cover 1 and cover plate 2, described cover plate 2 is welded on bearing end cover 1, it is characterized in that: described cover plate 2 is provided with intake-outlet 3 and for water circulating water chennel 5, described intake-outlet 3 includes water inlet and outlet, described water inlet with outlet respectively two ends with tank 5 be connected, described tank 5 be shaped as bend font, so can increase cooling water circulation distance, be conducive to more preferable cooling bearing, the mouth of a river of intake-outlet 3 is provided with the plug screw 4 for sealing, and described plug screw 4 is threaded connection with intake-outlet 3.
, described plug screw 4 is two, and after being respectively used to be sealed into water inlet and the water outlet of outlet 3, the material of described plug screw 4 is pyrite, can effectively prevent from getting rusty.
The method have the characteristics that, this device is widely used in water-cooled machine, it is particularly suited for the water-cooled machine of the hazardous area that explosive gas mixture exists, effectively electric motor back shaft can be held by built-in water circle device tank 5 and cool down, overcome shortcoming and a difficult problem that existing water-cooled machine can not cool down without fan housing rear bearing, extend the service life of bearing, it is ensured that the operation steady in a long-term of motor, shouldInventionThe design of device, all available extensively application of water-cooled machine in every field, and effect is notable.
Being described the present invention and embodiment thereof above, this description does not has restricted,In accompanying drawingShown is also one of embodiments of the present invention, and actual structure is not limited thereto.If those of ordinary skill in the art is enlightened by it, in the case of without departing from the invention objective, design the frame mode similar to this technical scheme and embodiment without creative, protection scope of the present invention all should be belonged to.
