Description
Technical field
The utility model relates to a kind of linkage structure, especially relates to a kind of connection set and has the wind wheel linkage structure of this connection set.
Background technique
Existing connection set shown in composition graphs 1 and Fig. 2, this connection set comprises: connecting plate 1, and this connecting plate 1 is provided with 2 to the first fixed hole 11; The central position of this connecting plate 1 is provided with the sleeve 2 for being socketed machine shaft, the middle part of this sleeve 2 is the first receiving bore 21 holding machine shaft, two ends of this sleeve 2 extend the bi-side of this connecting plate 1 respectively, be provided with a pair restraining groove 22 in two symmetrical positions of a wherein end of this sleeve 2, this restraining groove 22 is generally U-type groove or dovetail groove; Be provided with the first circular positioning step portion 3 at the madial wall of this sleeve 2, this first positioning step portion 3 is positioned at below the bottom land position of this restraining groove 22; Be provided with the second circular positioning step portion 4 at the outer side wall of sleeve 2, this second positioning step portion 4 is fixedly connected with connecting plate 1, and the surface in this second positioning step portion 4 is positioned at below the bottom land position of this restraining groove 22.During use, machine shaft arranges locating stud, two ends of this locating stud are located among a pair restraining groove 22, and machine shaft end is set among the first receiving bore 21 of sleeve 2, by screw, connecting plate 1 and impeller (or other elements) are fixed again, thus by this connection set, impeller (or wind wheel) is fixedly connected with machine shaft, motor can impeller be rotated.
But, because existing connection set to be positioned by a pair restraining groove 22 and spacing, inherently there is trueness error when processing restraining groove 22, causing the height of the bottom surface of 2 restraining grooves 22 inconsistent, thus the defect having two aspects at least can be caused:
1. the dynamic balancing difference value of this connection set is comparatively large, is unfavorable for the manufacturing operation utilizing this connection set.Such as, impeller is fixedly connected with connecting plate 1, connection set is connected with machine shaft by restraining groove 22, being now the first mounting point, during this first mounting point, the surface of connecting plate 1 is reference surface, when the second mounting point behind the position of exchange a pair locating stud in a pair restraining groove 22 (so-calledly to be exchanged, to be originally that the locating stud being positioned at the left side coordinates with the restraining groove being positioned at the left side exactly, now connecting plate 1 or machine shaft are rotated 180 °, originally the locating stud being positioned at the left side is coordinated) with the restraining groove being originally positioned at the right, now can there is a larger angle difference between the surface of connecting plate 1 and reference surface.That is, the height of the bottom surface of 2 restraining grooves 22 is inconsistent, to amplifying further the dynamic balancing difference value of connection set when two kinds of different mounting points, for production assembled belt carrys out inconvenience, affects manufacturing efficiency.
2. the height due to the bottom surface of 2 restraining grooves 22 is inconsistent, although can be revised by the balancing weight increasing suitable weight between contiguous block 1 and impeller, the geometry center of gravity of wind wheel is consistent with the central axis of machine shaft as much as possible, but the mode workload of this auxiliary correction is comparatively large, waste time and energy, reliability and less stable.

Wherein, the madial wall of this sleeve is provided with the second circular positioning step portion, and the height in the upper surface relative reference face in this second positioning step portion is less than the height in the upper surface relative reference face in this first positioning step portion.
Wherein, the madial wall of this sleeve is provided with the second circular positioning step portion, and the height in the upper surface relative reference face in this second positioning step portion equals the height in the upper surface relative reference face in this first positioning step portion.
Wherein, this connecting plate, this sleeve, this first positioning step portion and this second positioning step portion are all formed in one setting.
Wherein, this restraining groove is U-type groove or dovetail groove.
In addition, the utility model also comprises a kind of wind wheel linkage structure, and it comprises wind wheel and connection set, and the connecting plate of this connection set is fixedly connected with this wind wheel.
Compared with prior art, the utility model has following beneficial effect:
The connection set that the utility model proposes, still by the locating stud screens of restraining groove to machine shaft, but by the height in change second positioning step portion or/and the height in the first positioning step portion makes it the bottom land height being greater than restraining groove, thus by the upper surface in the second positioning step portion or/and the upper surface in the first positioning step portion is accurately located, and the diverse location of the upper surface in the second positioning step portion is or/and the diverse location of upper surface in the first positioning step portion is all easy to keep highly basically identical, thus the defect brought overcome by restraining groove screens simultaneously and location in prior art.In addition, the utility model structure is simple, realize that cost is lower, application prospect is extensive, both the man-hour utilizing the utility model connection set to process other products (wind wheel of such as range hood) can have been saved, enhance productivity, stability and the reliability of the product using the utility model connection set can also be improved.
