Abstract
Abstract This invention provides a roller bearing for linear sliding movement comprising a sliding block formed with a loading groove and a non-loading groove at the top end of the horizontal portion and at the lower end of the suspending portion, a pair of roller guides mounted at the top end of the horizontal portion and at the lower end of the suspending portion of the sliding block, a raceway block having upper and side rolling faces opposing to the respective loading grooves and a plurality of rollers circulating through each of the infinite roller tracks for receiving the load, in which the raceway block is perforated with attaching holes in perpendicular to the upper surface of the horizontal portion, a load acting line downwardly extended in perpendicular and slanted upwardly are applied relative to the mounting holes and a horizontal urging force is exerted to the side of the sliding block to apply a preloading.

Claim 1
Independent Claim
403 words
A roller bearing for linear sliding movement comprising a sliding block having a horizontal portion and a suspending portion suspended from the base end thereof and formed with a loading groove and a non-loading groove constituting a loading area and a non-loading area of an infinate roller track way respectively at the top end of the horizontal portion and at the lower end of the suspending portion, a pair of roller guides mounted at the top end of the horizontal portion and at the lower end of the suspending portion of said sliding block respectively and constitute the infinate roller track in combination with said loading groove and non-loading groove formed at the top end of the horizontal portion and at the lower end of the suspending portion, a raceway block having upper and side rolling faces opposing to the respective loading grooves formed at the top end of the horizontal portion and at the lower end of the suspending portion of said sliding block and a plurality of rollers circulating through each of the infinite roller track formed at the top end of the horizontal portion and at the lower end of the suspending portion of said sliding block in combination with said roller guides and receiving the load between each of the loading grooves on the side of the sliding block and each of the rolling faces on the side of the raceway block, in which said raceway block is perforated with mounting holes through which fixing bolts are passed and formed with said upper rolling face and the side rolling face relative to the mounting hole generally is perpendicular to the upper surface of the horizontal portion, a load acting line extended between the upper rolling face and the loading groove formed at the top end of the horizontal portion of the sliding block is directed in perpendicular to the upper surface of said horizontal portion, while another load acting line extended between the side rolling face and the loading groove formed at the lower end of the suspending portion of said sliding block opposing to the side roller face is slanted upwardly relative to the vertical line in perpendicualr to the upper surface of said horizontal portion and, upon fixing the sliding block to a movable body, preloading is applied by exerting an urging force from the side of the movable body to the side of the horizontal portion.

A roller bearing for linear sliding movement comprising a sliding block having a horizontal portion and a suspending portion suspended from the base end thereof and formed with a loading groove and a non-loading groove constituting a loading area and a non-loading area of an infinate roller track way respectively at the top end of the horizontal portion and at the lower end of the suspending portion, a pair of roller guides mounted at the top end of the horizontal portion and at the lower end of the suspending portion of said sliding block respectively and constitute the infinate roller track in combination with said loading groove and non-loading groove formed at the top end of the horizontal portion and at the lower end of the suspending portion, a raceway block having upper and side rolling faces opposing to the respective loading grooves formed at the top end of the horizontal portion and at the lower end of the suspending portion of said sliding block and a plurality of rollers circulating through each of the infinite roller track formed at the top end of the horizontal portion and at the lower end of the suspending portion of said sliding block in combination with said roller guides and receiving the load between each of the loading grooves on the side of the sliding block and each of the rolling faces on the side of the raceway block, in which said raceway block is perforated with mounting holes through which fixing bolts are passed and formed with said upper rolling face and the side rolling face relative to the mounting hole generally is perpendicular to the upper surface of the horizontal portion, a load acting line extended between the upper rolling face and the loading groove formed at the top end of the horizontal portion of the sliding block is directed in perpendicular to the upper surface of said horizontal portion, while another load acting line extended between the side rolling face and the loading groove formed at the lower end of the suspending portion of said sliding block opposing to the side roller face is slanted upwardly relative to the vertical line in perpendicualr to the upper surface of said horizontal portion and, upon fixing the sliding block to a movable body, preloading is applied by exerting an urging force from the side of the movable body to the side of the horizontal portion.
Claim 3
Dependent Claim
95 words
The roller bearing for linear sliding movement as defined in claim 1, wherein a mounting portion is protruded to the sliding block from the base end of the horizontal portion of said block on the side opposite to the horizontal portion, mounting holes capable of loosely engaging therethrough mounting bolts for mounting said sliding block to said movable body are perforated axially in two rows in said mounting portion and, upon fixing said sliding block to said movable body, said mounting bolts are mounted to the movable body passing through the mounting holes from below.
