Abstract
The utility model relates to an end cover of an exterior rotor flow fan, comprising an end cover of the motor, a waterproof cover, a sealing ring and a lead sealing cover; the end cover of the motor is provided with a bearing inlet and a lead outlet. The waterproof cover and the sealing ring seal the bearing inlet. The lead sealing cover seals the lead outlet; characterized in that the bearing inlet of the end cover of the motor is provided with a first circular waterproof step that is waterproof and the waterproof cover is provided with a flange under an circle outside of the first circular waterproof step so as to seal the bearing inlet; the lead outlet of the end cover of the motor is provided with a second circular waterproof step that is waterproof and the lead sealing cover is provided with a circular groove. The second circular waterproof step is inserted into the circular groove so as to seal the lead outlet. Because the first circular waterproof step matches the flange of the waterproof cover, great waterproof effect is exerted. Even under circumstance that waterproof performance of the sealing ring is reduced, the motor bearing inlet is waterproof. Because the second circular waterproof step is inserted into the groove, the lead outlet is waterproof.
Description
Technical field
The utility model relates to a kind of end cap of outer rotor shaft flow fan.
Background technology
The outer rotor shaft flow fan is mostly in the open air use, and as shown in Figure 1, prior motor waterproof end cap mainly is to come waterproof by waterproof cover and O RunddichtringO.Sealing ring occurs through regular meeting and change because of the influence of extraneous factor, the ponding of outside can enter motor, causes the class of insulation of motor to descend, and security performance can not get ensureing, simultaneously, can cause bearing failure because of entering of water motor is burnt out.In addition, therefore the motor internal metal part can get rusty, and causes decreased performance, lifetime.
The utility model content
The utility model provides a kind of ponding of outside can not enter motor internal in order to overcome the deficiencies in the prior art, the end cap of the outer rotor shaft flow fan that water resistance is good.
In order to achieve the above object, the technical solution adopted in the utility model is: it comprises electric motor end cap, waterproof cover, sealing ring and lead-in wire seal cover; Be provided with bearing inlet and lead outlet on electric motor end cap, waterproof cover and sealing ring are with the bearing inlet seal, and the lead-in wire seal cover seals lead outlet; It is characterized in that: be provided with the first annular waterproof step of waterproof action in the bearing porch of electric motor end cap, on waterproof cover, be provided with the annular lower flange that is set in outside the first annular waterproof step, thereby the bearing inlet seal is lived; Lead outlet place on electric motor end cap has been provided with the second annular waterproof step of waterproof action, is provided with an annular slot on the lead-in wire seal cover, and the second annular waterproof step is inserted in the annular slot, thereby lead outlet is sealed up.
Inwall at the bearing of described electric motor end cap inlet is provided with annular groove in, sealing ring be arranged in annular groove and with the wall fitted seal of waterproof cover.
The beneficial effect of this practical waterproof end cap is, the bearing inlet is provided with the first annular waterproof step, waterproof cover is provided with and is set in the outer annular lower flange of the first annular waterproof step, played good waterproof action, even under the situation that the sealing ring water resistance descends, the motor bearings porch is effective waterproof still.Lead outlet is provided with the second annular waterproof step, is provided with an annular slot on the lead-in wire seal cover, and the second annular waterproof step is inserted in the annular slot, can play good waterproof action.
