Anti-leakage device for an oily bearing

Abstract

An anti-leakage device for an oily bearing includes a base, a wearing piece, a fastener, a bearing, a spindle and a fan wheel. The base provides an axial barrel. The wearing piece, the fastener, the bearing and the spindle are received in the axial barrel. An oil removing disk is attached to an inner side of the fan wheel and provides a conical shell with a conical hole being enclosed with the conical shell such that the oil removing disk is capable of collecting lubrication oil with centrifugal force and the lubrication oil collected by the oil removing disk passes through the conical hole to allow the lubrication oil flowing outward the oil removing disk being forced to move back to the axial barrel.

1 . An anti-leakage device for an oily bearing comprising:
 a base providing an axial barrel;   a wearing piece being received in said axial barrel;   a fastener being received in said axial barrel and disposed on said wearing piece;   a bearing being received in said axial barrel and disposed on said fastener;   a spindle providing a first end and a second end with said first end passing through said bearing; and   a fan wheel being attached to said second end of said spindle;   characterized in that an oil removing disk is attached to an inner side of said fan wheel and provides a conical shell with a conical hole being enclosed with said conical shell such that said oil removing disk is capable of collecting lubrication oil with centrifugal force and the lubrication oil collected by the oil removing disk passes through said conical hole to allow the lubrication oil flowing outward said oil removing disk being forced to move back to said axial barrel.   
   
   
       2 . The anti-leakage device for an oily bearing as defined in  claim 1 , wherein said oil removing disk press-fits with said fan wheel for enhancing tightness. 
   
   
       3 . The anti-leakage device for an oily bearing as defined in  claim 1 , wherein glue type material is added between said oil removing disk and said fan wheel to intensify joint of said oil removing disk and said fan wheel. 
   
   
       4 . The anti-leakage device for an oily bearing as defined in  claim 1 , wherein said conical shell is provided with a spiral groove for the lubrication oil flowing back to an oil storage part provided at the bottom of said axial barrel. 
   
   
       5 . The anti-leakage device for an oily bearing as defined in  claim 1 , wherein at least a groove is provided at the outer surface of said bearing and extends from an end of said bearing to another end of said bearing. 
   
   
       6 . The anti-leakage device for an oily bearing as defined in  claim 1  wherein at least a spiral shaped groove is provided at the outer surface of said bearing. 
   
   
       7 . The anti-leakage device for an oily bearing as defined in  claim 5  wherein said groove has apertures communicating with an axial bore provided in said bearing spirally for guiding the lubrication oil into an oil storage recess provided at a surface surrounding said axial bore. 
   
   
       8 . The anti-leakage device for an oily bearing as defined in  claim 1 , wherein said bearing provides a plurality of radial groves at an upper end an a lower end of said bearing respectively for the lubrication oil flowing back to said oil storage part smoothly.
