The corrugated pipe shaft end seal device for the fan comprises a corrugated pipe, a seal body and a bearing seat support, wherein one end of the corrugated pipe is fixedly connected to an enclosure at the outlet of a fan shaft end, and the other end of the corrugated pipe is coaxially and fixedly connected with the seal body; the lower end of the seal body is provided with a mounting surface vertical to the seal body; the mounting surface and the upper surface of the bearing seat support are provided with matched mounting holes; and a mounting surface of the seal body is fixedly connected with the bearing seat support. According to the utility model, the problems existing in the prior art are solved, through adopting the corrugated pipe shaft end seal, in the mounting process, the corrugated pipe shaft end seal device for the fan provided by the utility model is convenient to regulate, is labor-time saving greatly, improves the working efficiency, is convenient to be standardized, is simple in structure, and is suitable for wide use.
Description
Technical field
The utility model relates to the blower fan industry, is specifically related to a kind of blower fan and uses the bellow type shaft end seal device.
Background technique
For the blower fan industry for, especially carry the blower fan of poisonous and harmful and explosive gas, its shaft end seal is very important.Seal us for this type of and generally adopt the carbocyclic ring sealing,, when it is installed its coaxality with axle is still had higher requirement though the carbocyclic ring sealing has certain self-regulating property.If coaxality is bad, then carbocyclic ring very easily weares and teares, thereby causes gas leakage.Sealing in the past is installed on the casing and inlet box sidewall that the shaft of blower fan goes out.For large-scale blower fan; Stator that casing inlet box etc. are formed and a rotor that belongs to general isolated footing installation, axle is very big with the coaxiality deviation of casing, need adjust the coaxality of casing and axle when on-the-spot installation seals repeatedly; Extremely take a lot of work, and extremely difficulty is adjusted to perfect condition.
The model utility content
The purpose of model utility: the utility model has solved the problem that existing technology exists, and provides a kind of easy-to-install blower fan to use the bellow type shaft end seal device.
Technological scheme: a kind of blower fan is used the bellow type shaft end seal device; Comprise bellows, seal and bearing bracket; On the casing that is fixedly connected on the outlet of blower fan axle head of one end of said bellows, the coaxial seal that is fixedly connected with of the other end of bellows, the lower end of seal is provided with the attachment face perpendicular with seal; The upper surface of attachment face and bearing bracket is provided with the mounting hole that matches, and said seal attachment face is fixedly connected with bearing bracket.
As optimization, the upper surface of said seal attachment face and bearing bracket is provided with the bearing pin that matches and the mounting hole of bolt, and said seal attachment face is fixedly connected with bearing pin through bolt with bearing bracket.
Beneficial effect: the utility model is through adopting the bellow type shaft end seal, easy to adjust in installation process, greatly practice thrift man-hour, increase work efficiency, be convenient to standardization, the utility model is simple in structure, is fit to be widely used.
