Background technology
Blower fan power transmission shaft is to be widely used in blower fan, such as the important accessory of centrifugal ventilating draught fan drive apparatus.
Blower fan power transmission shaft has higher requirement, existing blower fan power transmission shaft generally to use and add for sealing property
Dress sealing gasket stops internal grease seepage.
But, utilize oil sealing and sealing gasket to prevent the mode of internal grease seepage, due to oil sealing and sealing gasket
Aging, non-refractory, the factor such as deformation exist, and leakage of oil can not be stopped completely, need continually
Change oil sealing and sealing gasket.Thus blower fan transmission shaft structure of the prior art exist sealing effectiveness the best and
Seal the problem that cost is high.
Utility model content
In view of this, this utility model provides a kind of high sealing blower fan power transmission shaft, seals effect to realize improving
Really, the technical purpose of sealing cost is reduced.
A kind of high sealing blower fan power transmission shaft, including:
Blower fan power transmission shaft body, along described wind at the sealing of the input end of motor of described blower fan power transmission shaft body
The axis of rotation direction of machine power transmission shaft body is provided with tongue；
Connect below described blower fan transmission case side cover and be provided with groove, the spiral of described groove at the sealing of end
Direction is contrary with the described tongue hand of spiral；
It is provided with strip diversion groove below described blower fan transmission case side cover.
Preferably, described high sealing blower fan power transmission shaft also includes: be the most closely set in described blower fan transmission
At the sealing of axle body input end of motor and blower fan connect end built-in sealing ring.
A kind of fan transmission system, including: above-mentioned high sealing blower fan power transmission shaft.
From above-mentioned technical scheme it can be seen that the blower fan power transmission shaft of this utility model embodiment, in transmission
Offer screw thread on axle, and below blower fan transmission case side cover, be provided with strip diversion groove, in blower fan transmission
Axle is during the high speed rotating of axle center, and the oils and fats of spilling will be under the influence of centrifugal force along spiral lamination
And flow to described strip diversion groove, thus realize by transformation transmission shaft structure, it is achieved guide spillage oil
Fat is back to inside drive system, not only improves sealing effectiveness, and reduces frequently replacing sealing gasket and cause
Cost.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will
The accompanying drawing used required in embodiment or description of the prior art is briefly described.It should be evident that
Accompanying drawing in describing below is only embodiments more of the present utility model, for ordinary skill people
From the point of view of Yuan, on the premise of not paying creative work, it is also possible to obtain the attached of other according to these accompanying drawings
Figure.

Rotating shaft 6 rotation direction stating blower fan power transmission shaft body is provided with tongue 3 (seeing enlarged drawing)；
Connect at the sealing of end 4 below described blower fan transmission case side cover and be provided with groove 5, described groove 5
The hand of spiral is contrary with described tongue 3 hand of spiral；
It is provided with strip diversion groove 7 below described blower fan transmission case side cover.
At the sealing of described motor power shaft 2 and blower fan connect and 4 be respectively arranged with spiral side at the sealing of end
To contrary screw thread, described screw thread can be when rotating shaft 6 high-speed rotation, due to the effect of centrifugal force, overflows
Oils and fats enter in rotating shaft under the guiding of screw thread, and owing to being provided with bar below blower fan transmission case side cover
Shape diversion groove 7, continuation countershaft is lubricated by the oils and fats of spilling, thus solves existing high sealing wind
Machine drive shaft seal poor effect and seal the high problem of cost.
In order to improve sealing further, described high sealing blower fan power transmission shaft also includes: the most closely suit
At the sealing of described blower fan power transmission shaft body input end of motor and blower fan connect end built-in sealing ring (not
Illustrate).
It should be noted that the sealing means of described high sealing blower fan power transmission shaft, it is also possible to use built-in close
Seal coordinates the form that external sealing ring combines, and does not limit to.
This utility model embodiment further discloses:
A kind of fan transmission system, including: above-mentioned high sealing blower fan power transmission shaft.Described fan transmission system
Including electric machine structure, drive mechanism and impeller, described high sealing blower fan power transmission shaft is the weight in drive mechanism
