Description
Technical Field
The utility model relates to a fan field specifically is a fixed impeller structure.
Background
The impeller is the important component part of fan, and the impeller mainly divide into movable impeller and fixed impeller, and current fixed impeller's structure mainly includes: the motor shaft comprises a base plate and a plurality of blades evenly arranged on the base plate, wherein a shaft hole is formed in the middle of the base plate, and a motor shaft penetrates through the shaft hole in a sliding mode. In the use process of the fixed impeller, a motor shaft is usually connected with the impeller in a clamping mode by adopting a flat key so as to drive the fixed impeller to rotate, the monotonous clamping mode is long in time and easy to generate abrasion gaps, so that the motor shaft and the impeller vibrate and generate huge noise, and the use requirements of enterprises cannot be met.
SUMMERY OF THE UTILITY MODEL
The utility model provides a not enough to prior art, the utility model provides a decide impeller structure has solved some current wearing and tearing clearances that produce easily, makes to vibrate between motor shaft and the impeller, still can produce the problem of huge noise.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: a stator vane structure comprising: the base plate and evenly set up a plurality of blades on the base plate, be provided with the shaft hole at the middle part of base plate the motor shaft that slides in the shaft hole and wear to be equipped with evenly be provided with a plurality of splines on the motor shaft evenly be provided with a plurality of spline grooves with spline sliding fit on the base plate, the one end of spline groove seals on the base plate, the other end of spline groove runs through on the base plate be provided with damping rubber pad in the spline groove between spline and the base plate be provided with the spout respectively on the base plate between two adjacent spline grooves slide and be provided with the slider in the spout, the one end that the slider stretched into the spout is connected with the base plate through the spring be provided with the hemisphere fixture block on the other end that the slider stretched out the spout be provided with the hemisphere draw-in groove of mutually supporting with the hemisphere fixture block on.
Advantageous effects
The utility model provides a decide impeller structure. Compared with the prior art, the method has the following beneficial effects: the motor shaft adopts the spline groove card on spline and the base plate to establish, and set up damping rubber pad between spline and base plate, the base plate between two adjacent splines still realizes the secondary positioning function in the hemisphere draw-in groove of motor shaft through hemisphere fixture block secondary joint, the hemisphere fixture block can realize clearance compensation through the spring, offset with the motor shaft all the time, can effectively reduce the motor shaft and produce the wearing and tearing clearance after the base plate uses for a long time, reduce the vibration between motor shaft and the impeller, greatly reduced noise, long service life, satisfy the operation requirement of enterprise.
Drawings
Fig. 1 is a schematic structural diagram of the structure of the present invention.
Fig. 2 is a rear view structural diagram of fig. 1.
In the figure: 1. the base plate, 2, blade, 3, shaft hole, 4, motor shaft, 5, spline, 6, spline groove, 7, damping rubber pad, 8, spout, 9, slider, 10, spring, 11, hemisphere fixture block, 12, hemisphere draw-in groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: a stator vane structure comprising: a base plate 1 and a plurality of blades 2 evenly arranged on the base plate 1, a shaft hole 3 is arranged in the middle of the base plate 1, a motor shaft 4 is arranged in the shaft hole 3 in a sliding and penetrating way, a plurality of splines 5 are evenly arranged on the motor shaft 4, a plurality of spline grooves 6 which are in sliding fit with the splines 5 are uniformly arranged on the base plate 1, one end of each spline groove 6 is sealed on the base plate 1, the other end of each spline groove 6 penetrates through the base plate 1, a vibration damping rubber pad 7 is arranged in the spline groove 6 between the spline 5 and the base plate 1, sliding grooves 8 are respectively arranged on the base plate 1 between two adjacent spline grooves 6, a slide block 9 is arranged in the slide groove 8 in a sliding way, one end of the slide block 9 extending into the slide groove 8 is connected with the base plate 1 through a spring 10, a hemispherical clamping block 11 is arranged at the other end of the sliding block 9 extending out of the sliding groove 8, and hemispherical clamping grooves 12 matched with the hemispherical clamping block 11 are respectively arranged on the motor shaft 4.
During the installation, in inserting shaft hole 3 with motor shaft 4 from the one end that spline groove 6 runs through base plate 1, spline 5 on the motor shaft 4 inserts spline groove 6 on the base plate 1 respectively, when spline 5 inserts in spline groove 6 completely, hemisphere fixture block 11 is just right with hemisphere draw-in groove 12, hears to click and rubs a sound, and spring 10 promotes hemisphere fixture block 11 on the slider 9 and blocks and establish and realize the secondary positioning in hemisphere draw-in groove 12, prevents that motor shaft 4 from taking place to become flexible with the impeller after using for a long time.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
