Detailed Description
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, and it should be understood that the preferred embodiments are described herein for purposes of illustration and explanation, and not limitation.
As shown in fig. 1, 2, 3 and 4, the improved oil supply structure applied to the centrifugal fan comprises an oil chamber 1 and a connecting rod 2 fixedly connected with the oil chamber 1, wherein a plurality of oil outlet holes 21 are uniformly formed in the connecting rod 2, so that in the operation process of the centrifugal fan, oil stored in the oil chamber 1 can flow into the connecting rod 2 and then flows out through the oil outlet holes 21 to lubricate the machine. A hollow rotating shaft 3 is connected between the oil cavity 1 and the connecting rod 2, the rotating shaft 3 comprises an oil supply end 31 and an oil outlet end 32, the oil supply end 31 is communicated with the oil cavity 1, and the oil outlet end 32 extends into the connecting rod 2, so that oil in the oil cavity 1 flows from the oil supply end 31 to the oil outlet end 32 and then enters the connecting rod 2. Wherein the outer diameter of the oil supply end 31 is larger than the outer diameter of the oil outlet end 32, which enables the lubricating oil to sufficiently flow into the connecting rod 2. Still the cover is equipped with from packing gum cover 33 on the pivot 3, can make the staff can not polluted by lubricating oil when dismantling the installation to pivot 3, oil pocket 1 and connecting rod 2 like this, has also prevented lubricating oil simultaneously and has certain sealing performance. Be provided with spacer ring 4 between pivot 3 and oil pocket 1 and the connecting rod 2 respectively, its effect mainly plays sealed and strengthen the fixed effect of locking, has further promoted stability ability and practicality.
The aperture of the oil outlet 21 is increased from the inner wall of the connecting rod 2 to the outer wall of the connecting rod 2, so that the flow rate of the lubricating oil from the connecting rod 2 can be relatively reduced, and the waste of the lubricating oil is reduced.
In this embodiment, connecting rod 2 is cylindricly, and oil outlet 21 is located the middle part of connecting rod 2 and encircles the outer wall a week setting of connecting rod 2, can make the outflow of lubricating oil more even like this, and is effective.
To sum up, the utility model relates to a be applied to centrifugal fan's improved generation fuel feeding structure can make during the abundant flow of lubricating oil reaches connecting rod 2, has certain sealed effect simultaneously, has slowed down the speed that lubricating oil flows from connecting rod 2 in for the outflow of lubricating oil is more even effective, has reduced the waste of lubricating oil, and proclaim oneself gum cover 33 simultaneously and can also protect the staff, and whole steadiness can be strong, and the practicality is high, and is lubricated effectual.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
