Description
Technical field
The utility model relates to a kind of syndeton, especially relates to a kind of jockey and has the wind wheel syndeton of this jockey.
Background technology
Existing jockey shown in composition graphs 1 and Fig. 2, this jockey comprises: connecting plate 1, and this connecting plate 1 is provided with 2 to the first fixing hole 11; The center 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 accommodation hole 21 holding machine shaft, two ends of this sleeve 2 extend the two sides of this connecting plate 1 respectively, be provided with a pair stopper slot 22 in two symmetric positions of a wherein end of this sleeve 2, this stopper slot 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 stopper slot 22; Be provided with the second circular positioning step portion 4 at the lateral 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 stopper slot 22.During use, machine shaft arranges alignment pin, two ends of this alignment pin are located among a pair stopper slot 22, and machine shaft end is set among the first accommodation hole 21 of sleeve 2, by screw, connecting plate 1 and impeller (or other elements) are fixed again, thus by this jockey, impeller (or wind wheel) is fixedly connected with machine shaft, motor can impeller be rotated.
But, because existing jockey to be positioned by a pair stopper slot 22 and spacing, inherently there is trueness error when processing stopper slot 22, causing the height of the bottom surface of 2 stopper slots 22 inconsistent, thus the defect having two aspects at least can be caused:
1. the dynamic balancing difference value of this jockey is comparatively large, is unfavorable for the production operation utilizing this jockey.Such as, impeller is fixedly connected with connecting plate 1, jockey is connected with machine shaft by stopper slot 22, being now the first installation site, during this first installation site, the surface of connecting plate 1 is the plane of reference, when the second installation site behind the position of exchange a pair alignment pin in a pair stopper slot 22 (so-calledly to be exchanged, to be originally that the alignment pin being positioned at the left side coordinates with the stopper slot being positioned at the left side exactly, now connecting plate 1 or machine shaft are rotated 180 °, originally the alignment pin being positioned at the left side is coordinated) with the stopper slot being originally positioned at the right, now can there is a larger angle difference between the surface of connecting plate 1 and the plane of reference.That is, the height of the bottom surface of 2 stopper slots 22 is inconsistent, to amplifying further the dynamic balancing difference value of jockey when two kinds of different installation sites, for production assembled belt carrys out inconvenience, affects production efficiency.
2. the height due to the bottom surface of 2 stopper slots 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.
Utility model content
For overcoming the defect of prior art, the utility model proposes a kind of structure simple, realize the low jockey of cost, and there is the wind wheel syndeton of this jockey.
The utility model adopts following technical scheme to realize: a kind of jockey, comprise connecting plate, be arranged on the sleeve of the center of this connecting plate, this sleeve has the first end face and the second end face that are oppositely arranged, the central axis of this sleeve is vertical with this connecting plate, two symmetric positions of the first end face of this sleeve are provided with a pair stopper slot, and the lateral wall of this sleeve is provided with the second circular positioning step portion; With the second end face of this sleeve for the plane of reference, the height in the upper surface relative reference face in this second positioning step portion, is greater than the height in the bottom land relative reference face of this stopper slot, but is less than the height between the first end face of this sleeve and the second end face.
Wherein, the madial wall of this sleeve is provided with the first circular positioning step portion, and the height in the upper surface relative reference face in this first positioning step portion is less than the height in the upper surface relative reference face in this second positioning step portion.
Wherein, the madial wall of this sleeve is provided with the first circular positioning step portion, and the height in the upper surface relative reference face in this first positioning step portion equals the height in the upper surface relative reference face in this second 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 stopper slot is U-type groove or dovetail groove.
In addition, the utility model also comprises a kind of wind wheel syndeton, and it comprises wind wheel and jockey, and the connecting plate of this jockey is fixedly connected with this wind wheel.
Compared with prior art, the utility model has following beneficial effect:
The jockey that the utility model proposes, still by the alignment pin screens of stopper slot 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 stopper slot, 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 stopper slot 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 jockey to process other products (wind wheel of such as smoke exhaust ventilator) can have been saved, enhance productivity, stability and the reliability of the product using the utility model jockey can also be improved.
