Abstract
The embodiment of the invention discloses a highly-seal fan transmission shaft. The highly-seal fan transmission shaft comprises a fan transmission shaft body, and a convex groove is formed in the seal position of the motor input end of the fan transmission shaft body in the rotating direction of a rotating shaft of the fan transmission shaft body; a concave groove is formed in the seal position of a lower connecting end of a fan transmission box side cover, and the concave groove and the convex groove are opposite in spiral direction; a strip-shaped flow guiding concave groove is formed in the lower portion of the fan transmission box side cover. According to the fan transmission shaft provided by the embodiment of the invention, threads are arranged on the transmission shaft, and the strip-shaped flow guiding concave groove is formed in the lower portion of the fan transmission box side cover, so that when the fan transmission shaft rotates around the axis at a high speed, overflowing grease flows to the strip-shaped flow guiding concave groove along the threads under the action of centrifugal force; by modifying the structure of the transmission shaft, the overflowing grease is guided to flow back into a transmission system, so that not only is the sealing effect improved, but also cost caused by frequently replacing a sealing gasket is lowered.
Description
Technical field
The present invention relates to blower fan transmission renovation technique field, more specifically, it relates to a kind of high sealing blower fan transmission shaft and fan transmission system.
Background technology
Blower fan transmission shaft is widely used in blower fan, such as the important accessory of centrifugal ventilating draught fan transmission apparatus.
Blower fan transmission shaft has higher requirement for sealing property, and existing blower fan transmission shaft usually adopts and installs gasket prevention internal grease seepage additional.
But, utilize oil sealing and gasket to prevent the mode of internal grease seepage, owing to the factors such as aging, the non-refractory of oil sealing and gasket, distortion exist, and leakage of oil can not be stopped completely, it is necessary to frequently change oil sealing and gasket. Thus there is sealing poor effect and seal the high problem of cost in blower fan transmission shaft structure of the prior art.
Summary of the invention
In view of this, the present invention provides a kind of high sealing blower fan transmission shaft, improves sealing effect to realize, reduces the technical purpose of sealing cost.
A kind of high sealing blower fan transmission shaft, comprising:
Blower fan transmission shaft body, sealing place of the input end of motor of described blower fan transmission shaft body is provided with convex groove along the axis of rotation direction of described blower fan transmission shaft body;
Sealing place of lid lower section, described blower fan transmission case side coupling end is provided with groove, and the hand of spiral of described groove is contrary with the described convex groove hand of spiral;
Lid lower section, described blower fan transmission case side is provided with strip diversion groove.
Preferably, described high sealing blower fan transmission shaft also comprises: be closely set in described sealing place of blower fan transmission shaft body input end of motor and the built-in sealing-ring of blower fan coupling end respectively.
A kind of fan transmission system, comprising: above-mentioned high sealing blower fan transmission shaft.
As can be seen from above-mentioned technical scheme, the blower fan transmission shaft of the embodiment of the present invention, transmission shaft is offered screw thread, and lid lower section, blower fan transmission case side is provided with strip diversion groove, at blower fan transmission shaft in the process of axle center high speed rotating, overflow grease will under the influence of centrifugal force along spiricle and flow to described strip diversion groove, thus realize by transformation transmission shaft structure, realize guiding spilling grease to be back to transmission system inside, not only improve sealing effect, and reduce the frequent replacing cost that causes of gasket.
Accompanying drawing explanation
