Abstract
Provided is a corrosion resistant shaft end seal structure for a titanium centrifugal fan. The corrosion resistant shaft end comprises a fan hub, and a spindle penetrates into the fan hub and a shaft end pressing cover. A first groove is arranged on the outer side end face of the fan hub, a second groove is arranged on the outer side end face of the shaft end pressing cover, the shaft end pressing cover is fixedly connected with the fan hub through three bolts penetrating through a central hole and the position beside the central hole, a bolt penetrating through the central hole of the shaft end pressing cover is in threaded connection with a of a spindle in a shaft hole of the fan hub, and a check pad is arranged between the three bolts penetrating through the shaft end pressing cover and the shaft end pressing cover. The corrosion resistant shaft end seal structure for the titanium centrifugal fan has the advantages of being reasonable in structure, low in cost, easy to process and the like.
Description
Technical field
The utility model relates to a kind of sealing configuration, particularly relates to a kind of titanium centrifugal blower corrosion protection sealing structure of shaft end.
Background technique
At present, the sealing structure of shaft end of the blower fan of common material making comprises main shaft, floor clip, impeller nut etc.When the gas of blower fan conveying has corrosivity, main shaft with this structure is exposed to corrosive environment in a period of time, etchant gas enters screw-thread fit face and shaft hole matching face, and the main shaft expose portion produces corrosion, can produce larger gap between wheel hub and the main shaft.The shock value anomaly can occur during fan operation, the impeller equipment accident such as come off, damage that distortion even blade cracking are scrapped thereupon such as also can cause Leakage Gas, impeller to fly out to hurt sb.'s feelings at the security incident.
The model utility content
The utility model is used for overcoming the defective of prior art, and the structure of a kind of reliable solution titanium blower fan impeller shaft end sealing in corrosive environment is provided.
The technological scheme that adopts is:
A kind of titanium centrifugal blower corrosion protection sealing structure of shaft end, comprise axial fan hub, be arranged in main shaft and axle head gland in the axial fan hub, the outside end face that it is characterized in that described axial fan hub is provided with the first groove, the outside end face of axle head gland is provided with the second groove, inserted respectively seal ring in the first groove and the second groove, the axle head gland is fixedly connected with axial fan hub by three bolts that penetrate its center hole and center hole side, the bolt that axle head gland center hole penetrates penetrates in the axis hole of axial fan hub, and is connected with spindle thread in the axial fan hub axis hole.Penetrate between three bolts of axle head gland and the axle head gland and be provided with retaining pad.
The above-mentioned bolt that penetrates axle head gland center hole is articulation bolt.
The utility model can prevent the axial float of impeller, also can effectively avoid occuring because the main shaft corrosion causes the accident that titanium impeller comes off.The utility model has fundamentally solved the problem of transmission shaft end preserving and sealing in the aggressive medium.The utlity model has rational in infrastructure, the advantages such as cost is low, easy processing.
