Abstract
The utility model relates to an induction motor with an equalizing pressure sliding bearing, and an iron chip of the induction motor. The induction motor comprises a shell, and a stator, a rotor and a main shaft which are arranged inside the shell. The main shaft penetrates through the rotor and is connected with the rotor. A cable is arranged between the rotor and the stator. The connecting parts of two ends of the main shaft and the shell are provided with sliding bearings. The stator and the rotor are both provided with an axial ventilation hole and a radial ventilation groove. Two sides of the top part of the middle inside the shell are provided with wind guides which are connected with wind guide ducts. The wind guide ducts are connected with matching ducts which are connected with upper covers of the sliding bearings. The beneficial effects of the induction motor are that a problem of temperature rising of the sliding bearing of an asynchronous motor can be ensured, and a problem of oil leakage of partial self lubricating sliding bearing can be solved; and a reinforced air inflow to the internal part of the sliding bearing is performed through the matching ducts via a special wind path reconstruction so that an objective of equalizing pressure in the internal part and the external part of the bearing is achieved, and oil leakage is avoided.
Description
Technical field
The utility model relates to a kind of wind-driven generator, particularly relates to a kind of induction machine with all pressing sliding bearing.
Background technology
When threephase asynchronous machine turns round, the reasons in structure of the inner wind path of Yin Mada can produce negative pressure, causes the leakage of oil of part self-lubricating plain bearing, affects electrical machinery life, thereby loses market competitive power.Existing solution is for adopting forced-lubrication bearing to substitute, although scheme can solve Leakage, because of forced-lubrication bearing, inner grease chamber is less than self-lubricating, may cause the bearing temperature rise problem that transfinites.
The utility model content
The utility model is exactly in order to address the above problem, and overcomes the existing problem of mesohigh induction machine of the prior art, and the utility model provides a kind of induction machine with all pressing sliding bearing to satisfy the demands.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of induction machine with all pressing sliding bearing, comprise housing and be arranged at stator, rotor and the main shaft in housing, described rotor is arranged in stator, main shaft is connected with rotor through rotor, cable is arranged between rotor and stator, the junction, two ends of main shaft and housing is provided with sliding bearing, it is characterized in that, described stator and rotor are provided with axial ventilation hole and ventilation slot radially, the both sides of the interior center top of described housing are provided with wind and lead, wind is led the connection guide duct, the guide duct connecting pipings, and pipe arrangement connects the upper cover of sliding bearing.
Above-mentioned a kind of induction machine with all pressing sliding bearing, is characterized in that, described guide duct is the SGP pipe.
Above-mentioned a kind of induction machine with all pressing sliding bearing, is characterized in that, on the housing on described pipe arrangement side, is provided with for fixing the retainer ring of pipe arrangement.
Above-mentioned a kind of induction machine with all pressing sliding bearing, is characterized in that, described retainer ring is Φ 12 ball iron.
The beneficial effects of the utility model are: this utility model both can guarantee that the asynchronous machine sliding axle became problem of temperature rise, can solve the Leakage of part self-lubricating plain bearing again, force air inlet through pipe arrangement to sliding bearing inside by special wind path transformation, all press purpose so that bearing internal external section reaches, avoid leakage of oil.
The accompanying drawing explanation
Fig. 1 is that master of the present utility model looks cutaway view;
Fig. 2 is local amplification view of the present utility model;
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1 and Fig. 2, a kind of induction machine with all pressing sliding bearing, comprise housing 100 and be arranged at the stator 200 in housing 100, rotor 300 and main shaft 400, rotor 300 is arranged in stator 200, main shaft 400 is connected with rotor 400 through rotor 300, cable 500 is arranged between rotor 300 and stator 200, main shaft 400 is provided with sliding bearing 410 with the junction, two ends of housing 100, stator 200 and rotor 300 are provided with axial ventilation hole and ventilation slot radially, the both sides of housing 100 interior center top are provided with wind and lead 420, wind is led 420 connection guide ducts 430, guide duct 430 connecting pipings 440, pipe arrangement 440 connects the upper cover of sliding bearing 450.
In the time of work, during the motor operation, rotation by rotor 300 interior wings and partition, form negative pressuren zone in rotor 300 both sides, this negative pressure is by outside motor cold wind or through the interior gas of the cooling mistake of subcooler, top drilling inspiration motor end by housing 100 two ends, cold wind is entered the ventilation slot radially of rotor 300 by the axial ventilation hole of rotor 300, after the ventilation slot radially that enters stator core through air gap is again taken away heat, blow to the motor center top, the Exhaust Gas of housing center top leads 420 through wind, the rear importing sliding bearing of guide duct 430 and pipe arrangement 440 410 inside, to reach sliding bearing 410 internal pressurization effects.
In one of them preferred implementation of the present utility model, guide duct 430 is the SGP pipe.
Be provided with the retainer ring 450 for fixing pipe arrangement 440 on the housing 100 on pipe arrangement 440 sides, retainer ring 440 is Φ 12 ball iron.
The beneficial effects of the utility model are: this utility model both can guarantee that the asynchronous machine sliding axle became problem of temperature rise, can solve the Leakage of part self-lubricating plain bearing again, force air inlet through pipe arrangement to sliding bearing inside by special wind path transformation, all press purpose so that bearing internal external section reaches, avoid leakage of oil.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
