Wheel body and bearing of in-line skate

Abstract

A wheel body and a bearing of in-line skate capable of positioning rollers of a bearing so that stress thereof is dispersed evenly for preventing the loss of grease, intrusions of alien objects, and deformation and locking between the two bearing, thereby increasing the lifespan thereof, includes a spacing next an axletree having a sealed end and an open end further provided with a cover for sealing the axletree, and a bearing provided at recesses at the two sides thereof and consisted of an outer shell having a lengthened central axis, a containment ring having concaves and an outer cover for holding the rollers, thereby achieving a mechanism with enhanced practical values.

What is claimed is:  
     
         1 . A wheel body and a bearing of in-line skate for positioning rollers of a bearing thereof so that stress thereof is dispersed evenly for preventing loss of grease, intrusions of alien objects, and deformation and locking between the two bearing thereof, thereby increasing the lifespan thereof, comprising an axletree at the outer edge of a wheel body, a recess provided at the two sides of the wheel body for fitting the bearings, respectively, and a spacing having a partition provided for reducing production material and weight; and the characteristics thereof are that one side of the axletree is sealed and the other side thereof is in communication with open air with fitting holes provided at the partition of the spacing at the opening, and at the outer edge of the axletree is provided with an axletree cover having corresponding fitting axes for sealing the spacing; the bearing is further provided with an outer shell having a lengthened central axis, a containment ring having concaves and an outer cover for holding the rollers; the containment ring enclosing the rollers is sealed at the opening of the outer shell, and at the outer edge is of the outer shell is provided with an outer cover for covering the opening.  
     
     
         2 . The wheel body and a bearing of in-line skate in accordance with  claim 1 , wherein the lengthened central axis at the two sides from the bearing is free of gaps from joining, thus making intrusions of alien objects that further result in locking improbable.
