Description
The utility model relates to a kind of axial fan, particularly relates to a kind of spindle carrier of axial fan.
The radiation fan assembly was provided with central siphon in the framework of ccontaining fan in the past, and utilize the poor design in central siphon footpath, with bearing with urgent combination, in the embedding central siphon, and make the central shaft of impeller (rotor) penetrate bearing, and impeller central shaft terminal is provided with a circular groove, for element buckles such as C shape clasps.So, this impeller is articulated in the central siphon of radiation fan shell frame versatilely, becomes position rotating.This bearing has two types design, and a kind of is single bearing, and is to make single bearing that good location can be arranged, and adopts the bearing of the full whole shaft tube inner wall of embedding, articulate to support that central shaft is movable, but this device has the inconvenient problem of assembling.And, can increase the surface of contact of central shaft and bearing simultaneously, surface of contact is healed galling also the more.Therefore, can reduce the working life of fan.And another kind is a duplex bearing, it is at the upper and lower bearing of the urgent embedding of central siphon upper and lower end, and can reduce in the middle of the central siphon partly wall area of contact, but, if the bearing tool that embeds deviation or urgent combination degree a little differs, corresponding center line of this upper and lower two bearings and impeller central shaft center line just have offset problem, can't guarantee that fan center's axle can be in a fixedly straight line rotation, and be easy to generate noise.
The purpose of this utility model is to provide a kind of axle of this impeller that makes to reduce friction, and can reduce the member of radial journal bearing, with the spindle carrier of the axial fan that reduces production costs.
The spindle carrier of a kind of axial fan of the present utility model, comprise a substrate, an impeller and a housing that combines with this substrate, this substrate is provided with a base plate, be combined with most control pieces on this base plate, this impeller has a wheel hub, a central shaft reaches by this wheel hub one extension and is provided with most blades and a magnet ring, this impeller is according to central shaft rotation, and this impeller is to place this housing and substrate, it is characterized in that:
This substrate and housing respectively are provided with a supporting plate, and this two supporting plate respectively is provided with inwardly an arc recess, and this arc recess is two apical grafting end apical graftings with this central shaft that runs through this wheel hub.
The spindle carrier of described axial fan is characterized in that: this supporting plate and substrate, housing are one-body molded.
The spindle carrier of described axial fan is characterized in that: this supporting plate and substrate, housing are with the fastener secure bond.
The spindle carrier of described axial fan is characterized in that: these central shaft two apical grafting end end faces are formed with arc recess, and are provided with a rolling ball body between the arc recess of this central shaft and this substrate and housing supporting plate.
The spindle carrier of described axial fan is characterized in that: this supporting plate and central shaft are to make with wear-resistant material.
The spindle carrier of axial fan of the present utility model is by two substrates and the housing arc recess with supporting plate, for the central shaft two apical grafting end apical graftings rotation of impeller.So, this impeller has only less friction area when rotating, and can reduce the frictional heat of the two in a large number, more can reduce number of bearings simultaneously, and reduce production costs.
