Blade axis that possesses a reduced frictional area

Abstract

A blade axis that has reduced frictional area, one end of it is fixed at the back end center of the blade, and another end of it is inserted into the sliding bearing by using a clip to stop and fix it in the frame body, on the surface of the axis where it contacts the inner diameter surface of the sliding bearing is cut and processed with several dented slots to facilitate the insertion of the contact part of the axis to the sliding bearing to reduce frictional area, furthermore, the slot possesses a function of storing the lubricating oil, it creates a lubrication effect in the inner diameter surface of the sliding bearing, and the final goals of temperature reduction, noise reduction and life time enhancement can thus be achieved.

1 . A blade axis which can reduce the frictional area, one end of it is fixed to the back center of the blade, and another end of it is inserted into the sliding bearing and stopped and fixed inside the frame body by a clip, the axis has a contact part which contacts the inner diameter surface of sliding bearing cut and processed by several dented type slots to facilitate the reduction of frictional area when the contact part of the axis is inserted into the sliding bearing, meanwhile, the slot possesses the function of storing lubrication oil which in turn generates lubrication effect on the inner diameter surface of the sliding bearing, and the final goals of temperature reduction, noise reduction and lifetime enhancement can thus be achieved.  
   
   
       2 . The blade axis which can reduce the frictional area of  claim 1  wherein the several slots can be rectangular shape, V shape, semi circle arc shape, screw shape, saw-toothed shape . . . etc, they can be formed in staggered or continuous extension dented surface type.
