Patent ID: 8042244

Claim:
A bearing adjuster comprising: a grip including an impact receiver disposed thereon to provide for receiving impact from external forces; a rotatable wheel mounted with the grip, the rotatable wheel having a through hole centrally defined therein, the rotatable wheel having multiple arc grooves spirally and concentrically defined in a bottom thereof, a top of the rotatable wheel having multiple scales disposed on an edge thereof, the bottom of the rotatable wheel having multiple notches defined in an edge thereof and respectively corresponding to the multiple scales, the adjusting member having an inserting slot laterally defined therein, a position member partially received in the inserting slot and disposed on a lateral side of the rotatable wheel, the position member having a protrusion extended therefrom for corresponding to the notches of the rotatable wheel, the position member having an indicator disposed on a top thereof for cooperatively corresponding to the scales of the rotatable wheel; and an adjusting member having a spindle extending from a top thereof, the spindle connected to the grip via the through hole in the rotatable wheel, the adjusting member having multiple grooves radially defined therein for corresponding to the multiple arc grooves, each of the multiple grooves having a movable member movably received therein, each movable member having a stub extended from a top thereof and received in a corresponding one of the multiple arc grooves in the rotatable wheel; wherein the rotatable wheel is rotatable relative to the grip and the adjusting member; when the rotatable wheel is rotated, the stub of each movable member is pressed by the corresponding arc groove to move along the corresponding groove in the adjusting member such that each movable member is moved along the corresponding groove in the adjusting member for adjusting a distance between each other for being adapted to assemble with bearings having different sizes.
